A few months ago, I provided an overview of Polkinghorne’s views on natural theology. However, perhaps the best place to get acquainted with his position is to read the title chapter from his book, Belief in God in an Age of Science. First delivered as the Terry Lectures at Yale University in October 1996, this eloquent little book contains five chapters and a short epilogue. Readers are invited to explore the rest of the book on their own. I especially recommend the highly original second chapter (“Finding Truth: Science and Religion Compared”), in which he compares the ways in which physicists struggled to understand the dual nature of light (as a wave or a particle) in the early twentieth century with the ways in which early Christian thinkers struggled to understand the dual nature of Jesus (as divine and human). Unfortunately we won’t be presenting additional chapters here, but neither the print nor the electronic version of the book is very expensive!

In the fourth sentence below, Polkinghorne defines “belief in God” in terms of the proposition “that there is a Mind and a Purpose behind the history of the universe.”  This excerpt presents some evidence for a divine mind behind the visible world revealed to us by science, while the next (coming in about two weeks) discusses some evidence for divine purpose.

My editorial policy for these excerpts is explained at the bottom of this post.

Belief in God in an Age of Science (part 1)

What does it mean to believe in God today? Different religious communities propose different answers to that fundamental question. I speak from within the Christian tradition, though much of what I say in this chapter would, I believe, find endorsement from my Jewish and Islamic friends. For me, the fundamental content of belief in God is that there is a Mind and a Purpose behind the history of the universe and that the One whose veiled presence is intimated in this way is worthy of worship and the ground of hope. In this chapter, I sketch some of the considerations that persuade me that this is the case.

The world is not full of items stamped “made by God”—the Creator is more subtle than that—but there are two locations where general hints of the divine presence might be expected to be seen most clearly. One is the vast cosmos itself, with its fifteen-billion-year history of evolving development following the big bang. The other is the “thinking reed” of humanity, so insignificant in physical scale but, as Pascal said, superior to all the stars because it alone knows them and itself. The universe and the means by which that universe has become marvelously self-aware—these are the centers of our enquiry.

Those who work in fundamental physics encounter a world whose large-scale structure (as described by cosmology) and small-scale process (as described by quantum theory) are alike characterized by a wonderful order that is expressible in concise and elegant mathematical terms. The distinguished theoretical physicist Paul Dirac, who was not a conventionally religious man, was once asked what was his fundamental belief. He strode to a blackboard and wrote that the laws of nature should be expressed in beautiful equations. [Remember that Polkinghorne was a student in Dirac’s lectures on quantum physics; see here.] It was a fitting affirmation by one whose fundamental discoveries had all come from his dedicated pursuit of mathematical beauty. This use of abstract mathematics as a technique of physical discovery points to a very deep fact about the nature of the universe that we inhabit, and to the remarkable conformity of our human minds to its patterning. We live in a world whose physical fabric is endowed with transparent rational beauty.

Attempts have been made to explain away this fact. No one would deny, of course, that evolutionary necessity will have molded our ability for thinking in ways that will ensure its adequacy for understanding the world around us, at least to the extent that is demanded by pressures for survival. Yet our surplus intellectual capacity, enabling us to comprehend the microworld of quarks and gluons and the macroworld of big bang cosmology, is on such a scale that it beggars belief that this is simply a fortunate by-product of the struggle for life. Remember that Sherlock Holmes told a shocked Dr. Watson that he didn't care whether the Earth went round the Sun or vice versa, for it had no relevance to the pursuits of his daily life!

Even less plausible, in my view, is the claim sometimes advanced that human beings happen to like mathematical reasoning and so they manipulate their account of physical process into pleasing mathematical shapes. [Polkinghorne cites Andrew Pickering, Constructing Quarks, p. 413] Nature is not so plastic as to be subject to our whim in this way. In 1907, Einstein had what he called “the happiest thought of my life,” when he recognized the principle of equivalence, which implied that all entities would move in the same way in a gravitational field. This universality of effect meant that gravity could be expressed as a property of space-time itself; physics could be turned into geometry. Einstein then embarked on a search for a beautiful equation that would determine the relevant geometrical structure. It took him eight years to find it, culminating in the discovery of the theory of general relativity in November 1915. It was a truly beautiful theory but now came the moment of truth. On 18th November, Einstein calculated the prediction made by his theory for the motion of the planet Mercury. He found that it precisely explained a discrepancy in relation to Newton’s theory that had baffled astronomers for more than sixty years. Einstein’s biographer, Abram Pais, says “This discovery was, I believe, by far the strongest emotional experience in Einstein’s scientific life, perhaps in all his life. Nature had spoken to him.” Whilst the great man himself said, “For a few days, I was beside myself with joyous excitement.” [Abraham Pais, Subtle is the Lord: The Science and the Life of Albert Einstein, p. 253]. It was a great triumph but, if the answer had not come out right, the aesthetic power of the equations of general relativity would have been quite unable in itself to save them from abandonment. It was indeed nature that had spoken.

There is no a priori reason why beautiful equations should prove to be the clue to understanding nature; why fundamental physics should be possible; why our minds should have such ready access to the deep structure of the universe. It is a contingent fact that this is true of us and of our world, but it does not seem sufficient simply to regard it as a happy accident. Surely it is a significant insight into the nature of reality. I believe that Dirac and Einstein, in making their great discoveries, were participating in an encounter with the divine.

It has become common coinage with contemporary writers about science to invoke, in addressing the general public, the idea of a reading of the Mind of God. [Polkinghorne cites Paul Davies, The Mind of God and Stephen Hawking, A Brief History of Time.] It is a small, but significant, sign of the human longing for God that apparently this language helps to sell books. There is much more to the Mind of God than physics will ever disclose, but this usage is not misleading, for I believe that the rational beauty of the cosmos indeed reflects the Mind that holds it in being. The “unreasonable effectiveness of mathematics” in uncovering the structure of the physical world (to use Eugene Wigner’s pregnant phrase) is a hint of the presence of the Creator, given to us creatures who are made in the divine image. I do not present this conclusion as a logical demonstration—we are in a realm of metaphysical discourse where such certainty is not available either to believer or to unbeliever—but I do present it as a coherent and intellectually satisfying understanding.

Looking Ahead

We continue with the excerpt on purpose in about two weeks.

Editorial Policy

Most of the editing for these excerpts involves breaking longer paragraphs into multiple parts, altering the spelling and punctuation from British to American, removing the odd sentence or two—which I indicate by putting [SNIP] at the appropriate point(s)—and sometimes inserting annotations where warranted [also enclosed in square brackets] to provide background information. Polkinghorne uses footnotes a bit sparingly, and I usually find another way to include that information if it’s important for our readers.

Despite this usage, most of us know that randomness has something to do with probability, and that it often implies a lack of conscious intentionality. But what do mathematicians and scientists mean when they say something is random? Can a random process lead to an ordered, even predictable outcome? Is there evidence that God makes use of random processes to fulfill his creative purposes?

These are big questions, and we won’t address them all today. But I think randomness is an important topic to cover for two reasons: 1) it is integral to many processes in biology (and math, physics, chemistry, etc.), and 2) it is commonly misunderstood to be incompatible with Christianity.

As I said above, most of us know that randomness has something to do with probability. If you pick a card “at random” from a shuffled deck, you have a small probability of drawing an ace (4 out of 52, or a 7.7% chance). If you flip a coin, you have an equal probability of getting heads or tails.

Randomness also seems to imply a lack of intentionality or purposefulness. After all, you might hope for an ace when you draw a card, but you can’t choose one on purpose. You might call heads when you flip a coin, but you can’t know beforehand what the outcome will be. Thus the outcome is indeterminate, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.

It should be noted that indeterminacy does not imply that God does not have foreknowledge of future events. Christians ought not to be uncomfortable with the idea of God interacting with his creation through chance. We often describe a seemingly-random (i.e. unplanned by us) sequence of events as being “providential,” or planned by God.

In biology, it is very hard or impossible to calculate precise probabilities for most processes, so when we say a process is random, we typically mean it is extremely unpredictable. Eventually we will discuss randomness within biological evolution, but first we must consider some simpler processes, like the self-assembly of a virus.

Viruses are remarkably efficient entities. Coiled tightly within a protein-based shell is a small amount of DNA needed for self-replication. The shell, called a capsid, is made of many repeating protein subunits and is therefore highly symmetrical (see figure). Important biomedical insights have certainly been gleaned from structural studies of viruses, but viruses also teach us about the emergence of order from non-order.

The virus life cycle has four main steps: 1) enter a host cell, 2) hijack the cell’s replication and translation machinery to make many copies of itself, 3) assemble into many virus particles, and 4) exit the cell to invade another host.

When I first learned about this process, I found it very hard to believe it just “happens.” The idea that a bunch of molecules bumping into each other inside a crowded cell could spontaneously assembly into a fully-functional virus seemed a bit far-fetched. Many viral capsids have over 100 protein subunits that must interact with each other in just the right way, or it won’t work. Surely there must be something driving this process, right?

There is! Random motion. I had to see it to believe it. I distinctly remember sitting in class during my first year of graduate school when the professor demonstrated self-assembly of a virus using a 3D model as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.

As the narrator explains, sub-assemblies form and break apart en route to the most stable structure, the full capsid. As the sub-assemblies begin to form, further associations with free subunits become more favorable and as a result occur rapidly, while the final steps may take considerably longer. While the subunits in the model are rigid, in reality the proteins take on multiple conformations, allowing the capsid to “breathe.”

Amazing as it is, the system we just considered—one virus capsid in a jar—is pretty simple. One wonders how self-assembly can happen in a crowded cell, where there are countless other molecules diffusing around, potentially getting in the way. We can’t directly see how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.

Consider two viruses, where each protein subunit in one virus is the mirror image of the corresponding subunit in the other. Putting the two viruses together by hand would be pretty tricky, because the constituent parts look so similar. But random motion can do the job in short order:

From this model, we can see clearly, in real-time, how distinct complex structures can arise from their parts randomly interacting with one another. Many large viruses also use special scaffolding proteins to assist in the assembly process, and some even use their own genomes as a scaffold. In addition, two closely-related viruses that happen to infect the same cell can exchange parts to create a new virus. This is one way viruses can evolve quickly to evade the host’s immune system.

Here we have seen how viruses demonstrate a principle inherent in God’s world—that order can emerge out of chaos from random processes. In my next post, we will look at some other biological processes that make use of—rather, depend on—randomness. This will set the stage for us to see that such processes can not only assemble a structure within seconds or minutes, but also generate complex, information-bearing molecules over billions of years. Even though the freedom inherent in nature sometimes produces unintelligently-designed structures (like viruses, which can kill us), we see that God has made, and continues to oversee by his providence, a good creation that, at least in part, is capable of creating itself.

Next weekend, we’ll continue this series about randomness and God’s divine will. Up next: how God created the body to heal itself, and how can random mutations can be both harmful and benign.

The tenth anniversary of the human genome has been marked by some striking new genetic insights into human evolution and diversity. Do these new discoveries have any significance for the dialogue between science and religion in general, or for our sense of human uniqueness in particular?

The publication of the Neanderthal genome sequence in May 2010 set the pace. Not surprisingly -- given that our last common ancestor with the chimpanzee was around 5 to 6 million years ago, compared to a mere half a million years for our last common ancestor with the Neanderthal -- it turns out that we are genetically far closer to the Neanderthals than to the apes. In all, only seventy-eight changes in the genetic letters ('nucleotides') that would change the amino acid sequence of particular proteins were found in the Neanderthal DNA that were the same as the chimpanzee sequence but different in the human. Amongst other differences, 111 duplications of small DNA segments were found in the Neanderthal but not human sequence. Genetically we are closely related twigs on the great evolutionary bush of life.

But we knew that already. More surprising for many was the provocative finding that non-African humans are genetically closer to Neanderthals than African humans. In fact, the European and Asian genomes that were sequenced appear to contain one to four percent DNA of Neanderthal origin, and the gene flow that occurred appears to have been almost entirely from Neanderthal to human, rather than vice versa. How come? The most likely scenario is that there were a few instances of sexual reproduction between Neanderthals and human individuals belonging to the population that is thought to have emigrated out of Africa to populate the world sometime after seventy thousand years ago, explaining why the Neanderthal DNA sequences are not found in African genomes. The contribution of the Neanderthal genome has remained in European and Asian populations ever since.

To put this in perspective, most of our genes are very similar anyway to those found in Neanderthals and chimpanzees, and to other mammals like mice. We all share a "how-to-build-a-mammal" instruction manual, and the relatively minor genetic differences between us (minor relative to those we share in common) are the icing on the cake, as it were, that make us a human rather than a mouse, a chimp or a Neanderthal.

The year 2010 saw yet another twig appear on the hominin branch of the evolutionary bush, this time one even closer to the Neanderthals than our own. This story begins with the discovery by a Russian team of a sliver of finger bone from a remote Siberian cave in the Altai Mountains, known as the Denisova Cave. The team stored it away, thinking it was from one of the Neanderthals that frequented the cave between thirty thousand and forty-eight thousand years ago. But when DNA extracted from the bone was eventually sequenced, the results -- published just before Christmas -- revealed a population distinct from both humans and Neanderthals.

The finger appears to belong to a novel hominin population that shared a last common ancestor with Neanderthals more recently than humans, and overall is genetically closer to Neanderthals than to humans. It is too early to say whether the so-called 'Denisovans' represent a separate species and fossil data will be required to clarify that question. But what the results do suggest is that Melanesians -- the inhabitants of Papua New Guinea and islands northeast of Australia -- have inherited as much as one-twentieth of their DNA from the 'Denisovans', indicating that some limited inter-breeding took place between these ancient populations. Most fascinating of all is the idea that multiple hominin lineages were coexisting in Europe and Asia, along with modern humans, as recently as twenty-thousand to forty-thousand years ago.

Do these findings have any particular theological significance? It is difficult to know why this should be the case. In the Judeo-Christian tradition humankind uniquely is made "in the image of God". The suite of capabilities that emerged during human evolution is necessary but not sufficient to do justice to this much discussed theological insight. Our particular genetic instruction manual generates large frontal lobes, advanced cognitive abilities, rationality, language, consciousness and the ability to choose between right and wrong. It is this suite that gives us the ability to pray, worship and engage in communal religious practices.

But the idea of being made "in the image of God" is not encompassed simply within a static list of such human qualities. Theologians have drawn attention to the dynamic, relational aspects of the concept. It is humanity-in-relation-to-God, together with God-given responsibilities to humans in relationship with each other, that are thought to be more central to the idea. When did such spiritual capabilities and responsibilities first come into being? It is really difficult to know, but the answer certainly seems more rooted in God's intentions and purposes for humankind than in genetic change per se. Students can spend a long time being trained in the finer points of drama, but the play only gets off the ground when the actors are finally given their lines.

It seems quite likely that more twigs will continue to appear on the hominin branch of the bush of life as genomics continues to extend its reach. Such discoveries as such do not appear to raise any new theological questions. But other 2010 discoveries did highlight two genomic insights that do have relevance for religious views of human identity. The first insight comes from further Genome Wide Association studies that continue to subvert any lingering commitments to genetic determinism, for example the idea that there are genes "for" a particular human trait. The second insight comes from the finding that we are all more genetically different from each other than we realized even a few years ago. Genetics is underlining the uniqueness of each human individual. By the end of 2011 it is estimated that more than 30,000 human genomes will have been sequenced. Watch this space. Theological reflections on these findings will be the topic for Part 2.

Suppose a man falls among thieves, or wild beasts; is shipwrecked at sea by a sudden gale; is killed by a falling house or tree. Suppose another man wandering through the desert finds help in his straits; having been tossed by the waves, reaches harbor; miraculously escapes death by a finger’s breadth. Carnal reason ascribes all such happenings, whether prosperous or adverse, to fortune. But anyone who has been taught by Christ’s lips that all the hairs if his head are numbered [Matt. 10:30] will look further afield for a cause, and will consider that all events are governed by God’s secret plan.

In this passage, Calvin presents belief in “fortune” as evidence of carnal reasoning, and statements like this one have contributed to a widely-held notion that modern scientific understandings of the role that randomness plays in nature is inconsistent with belief in divine providence. In other words, if “randomness” equals blind and capricious “fortune,” then how can God be said to be working all things to his ends?

But Calvin could not have known of the very different understanding of randomness held by today’s scholars. Physical scientists, mathematicians, and statisticians have not yet agreed on a single unambiguous definition of the term “randomness,” but among these scientists, the term consistently refers to a family of related concepts focusing on unpredictability of the outcomes of single events and the absence of pattern in sequences of outcomes. I like this statement by John Polkinghorne, “Chance doesn't mean meaningless randomness, but historical contingency. This happens rather than that, and that's the way that novelty, new things, come about.” In Polkinghorne’s view, chance is an agent of creativity and can be perceived as being purposeful.

In fact, there are abundant examples of phenomena in nature in which randomness plays a role one could understand as being purposeful. For example, osmosis is a marvelous mechanism that enables all 10 trillion cells in our bodies to be nourished – it depends on the random motion of molecules. The human immune system is able to defend the body against attacks from millions of different microorganisms using a relatively small number of building blocks and random combinations of these to fashion defenses specific to each adversary. We never take a breath and find it to be all nitrogen or carbon dioxide – random motion of molecules keeps oxygen close to uniformly distributed throughout the atmosphere.

In 2007, a British statistician, David Bartholomew published God, Chance, and Purpose in which he argues that God “can have it both ways”—that he can use low level randomness to accomplish divine purposes while simultaneously maintaining order at a higher level. Of course, we cannot prove that God ordained these random processes to achieve divine purposes in the world. But to a person of faith, such an interpretation in both consistent with the observations we make in science and with the Scriptural notion of God’s providential care for the world.

Considerations like these led the John Templeton Foundation to provide a generous grant of $1.69 million to support a new research initiative on the theme of Randomness and Divine providence. Beginning this past summer, the program has the purpose of providing support for solid theoretical exploration of the kinds of ideas and possibilities expressed above—involving theology, philosophy, natural science, mathematics, and statistics. The grant will support individual scholars and teams of scholars who are willing to devote a significant amount of time between March of 2013 and June of 2015 to such work, and the project’s request for proposals suggests the following as questions researchers might pursue:

• How might God work providentially through indeterminate processes? Can recent advances in understanding the nature of randomness offered by algorithmic information theory, physics, biology, and other sciences provide insight into this question?
• Can we bring clarity to the concept of "randomness"? Philosophers and scientists have tried on occasion to give precise definitions of when a process is random, but more work needs to be done on the question. How do (or should) conceptions of randomness vary across academic disciplines?
• What are some possible implications of randomness for hiding or unfolding divine creativity and purpose in the world? Could God use randomness to (1) generate creativity, (2) hide divine actions, or (3) unfold information? Why might God do so?
• How might we identify and come to understand a significant collection of nondeterministic processes in which agents could intentionally employ randomness to bring about purposeful results?
• How might we mathematically and physically model random processes in ways that help us understand how divine providence could be exercised in a "chance-governed" world?
• How do "laws and orders" in nature interplay with "chance and randomness" in bringing about results that can be interpreted as aspects of divine providence?
• Might randomness be evidence of limitations in human knowledge but nothing more? Or might it be evidence of ontological indeterminism? Might this be tested?
• What implications does randomness have for aspects of God’s relationship with the physical world such as God’s relationship to time and God’s role in causation? How might randomness be reconciled with God’s foreknowledge?
• How might an understanding of providence based on an extended Molinism and/or open theology incorporate randomness? For example, could an extended Molinism provide a plausible account of the relationship between quantum mechanics and divine providence?
• What are some theodical implications of randomness, particularly for the issue of natural evil?
• How have the theological traditions of Augustine, Maimonides, Aquinas, Luther, and Calvin addressed chance and fortune? In what ways might they incorporate ontological randomness?
• How do or could religions other than the Judeo/Christian tradition understand and incorporate randomness?
• How is the concept of randomness understood by advocates of secularism, naturalism, and new atheism? What are the strengths and weaknesses of these usages?
• How might an understanding of randomness in the world alter our conceptions of divinity, especially our understanding of divine providence?

Despite the range of issues mentioned above, research is by no means restricted only to these topics. In fact, the structure of the program is designed to foster collaboration and build community between scholars, with the end of expanding the range and integration of their work: two conferences will be held to bring scholars together with each other and then with members of the public—one at Calvin College in 2013 and the other at Fuller Theological Seminary in 2015. To get more information and to learn how to submit a proposal, see the project website; then join us in exploring the truth that all creation glorifies God—even randomness!

In my previous essay, I discussed “Darwin’s finches” and how surprisingly little Charles Darwin himself had to say about them. In fact, it was actually the British ornithologist David Lack (1910-1973) who conducted the critical research that immortalized the finches in biology textbooks and popular lore. In 1973, the eminent German zoologist Ernst Mayr wrote:

Already well known among professional ornithologists, his work on the Galapagos finches gave David Lack world fame… There is no modern textbook of zoology, evolution or ecology which does not include an account of his work.¹

Ernst W. Mayr

Decades have passed since Mayr wrote these words, and David Lack’s name has largely faded from public discourse. On the other hand, the Galapagos finches have become one of the most recognized symbols of evolution in the world today. Does it really matter whether Lack or Darwin gets credit for describing the evolution of these remarkable birds?

Insofar as evolutionary theory contrasted with religious belief, it makes a big difference. In a culture that is eager to equate evolution with atheism, it should come as no surprise that these birds are only known as “Darwin’s finches”. Darwin’s personal struggles and ultimate rejection of Christianity are well documented, and people are eager to link his loss of faith to his evolutionary theory. David Lack, on the other hand, began his scientific career as an agnostic, but shortly after publishing his famous book on the evolution of Galápagos finches, he converted to Christianity! ²

A Christian at the forefront of evolutionary biology

Lack’s Christian conversion did not mark the end of his scientific achievements, either. In fact, he continued as a prolific researcher until just weeks before he died. Among his many achievements, he was Director of the Edward Grey Institute of Field Ornithology (1945-1973), Fellow of the Royal Society, and President of both the International Ornithological Congress (1962-66) and the British Ecological Society (1964-65). His fellow scientists held him in great esteem:

He was described as one of the most outstanding among world ornithologists; he was certainly this, but he was also one of the world’s leading evolutionists. All the time one saw developing his use of birds as material for the study of wider, deeper, biological problems.³

David Lack at the International Ornithological Congress, 1962.

Clearly David Lack was an outstanding scientist, and his commitment to Christianity did not tarnish, hinder, or undermine his research on evolution. But we might also ask, what was Lack like as a Christian? Did he keep his faith hidden from view, afraid that it might compromise his reputation as a scientist? Ernst Mayr, who interacted with David Lack professionally and personally for nearly 40 years, had this to say:

I have known only few people with such deep moral convictions as David Lack. He applied very high standards to his own work and was not inclined to condone shoddiness, superficiality and lack of sincerity in others. This did not always go well with those who preferred to compromise in favour of temporary expediency. David had been raised in an environment in which great stress was layed on moral principles and this attitude was later reinforced by his Christian faith. This explains his extraordinary unselfishness and modesty, and his great devotion to his family, to his students, to his friends, and to all the things that he lived for. The equanimity, indeed serenity, with which he faced death after his terminal cancer had been diagnosed is further evidence of the strength which his faith gave him.⁴

Like Asa Gray⁵ before him, and Francis Collins⁶ after, David Lack was an sincere, devout Christian, as well as a leading scientist who employed evolutionary theory to make brilliant discoveries about the natural world. Though Lack did not see any conflict between his scientific and Christian beliefs, he was sympathetic to the concerns of his fellow Christians. Therefore, ten years after publishing his masterpiece on Darwin’s Finches, Lack wrote another book entitled Evolutionary Theory and Christian Belief: The Unresolved Conflict.

Originally published in 1957, this book deals with the very same science and faith questions that Christians struggle with today— topics like randomness and chance, death in nature, miracles, and evolutionary ethics. While it would be unreasonable to expect anyone to completely resolve these matters, Lack offered numerous insights both as a devout Christian and one of the world’s leading biologists.

Let’s take a brief look at how Lack addressed some of these questions.

Blind Chance or Divine Plan?

Evolutionary theory does not invoke supernatural forces in explaining the history of life on Earth; instead, it relies on naturally-occurring processes to account for the vast diversity of life. Additionally, it explains animal behavior largely in terms of survival and reproduction, without appealing to any higher purpose of life. Taken together, does this imply that God is absent, and that our lives are ultimately meaningless?

David Lack responded,

Behind the criticism that Darwinism means that evolution is either random or rigidly determined lies the fear that evolution proceeds blindly, and not in accordance with a divine plan. This is another problem that really lies outside the terms of reference of biology. It is true that biologists have inferred that, because evolution occurs by natural selection, there is no divine plan; but they are being as illogical as those theologians whom they rightly criticize for inferring that, because there is a divine plan, evolution cannot be the result of natural selection.⁷

When rendering judgment on the ultimate meaning of life, biologists are speaking from their person beliefs, not from scientific authority. Moreover, Lack pointed out that many science enthusiasts have employed the concept of “randomness” in ambiguous and misleading ways:

Mutations are random in relation to the needs of the animal, but natural selection is not. Selection, as the word implies, is the reverse of chance.⁸

In support of his view, Lack pointed out that convergent evolution has produced uncanny resemblances between distantly-related species across the world, notably among marsupials in Australia. Different evolutionary trajectories can lead to very similar results.⁹

Death in Nature

After addressing concerns about the seeming “randomness” of evolution, Lack turned to another great concern, the role of death in natural selection:

Various writers–some Christian and others agnostic–have been troubled about natural selection not only because it seems too random, but also because it is so unpleasant.¹⁰

Genetic mutations are generally harmful, and for evolution by natural selection to produce new forms of life, an awful lot of organisms must die. For many Christians, it is inconceivable that a loving and merciful God would allow death on such a vast scale.

But Lack also pointed out that rejecting evolutionary theory doesn’t actually get rid of the problem of death. Regardless of what we think about evolution, the brute fact of mass extinction remains. Fossils of innumerable animals, plants, and microorganisms clearly demonstrate that the vast majority of species that have ever lived are now dead. It may be quite troubling for us to observe that our planet is a giant graveyard of natural history, but rejecting evolution will not change this fact.

Some Christians conclude that death could not have been part of the divine plan; instead, it must be the work of the devil, or the result of human sin. But this interpretation contains an implicit assumption that death is always evil. Is this really true? David Lack offered two intriguing insights:

1. For a population to maintain a stable size, all births must be balanced by a corresponding number of deaths. A world in which no animals die is a world in which no animals are born. That means no reproduction, no courtship, and by implication, no singing birds—much to the dismay of ornithologists and people in love!

2. Some people, taking cues from Isaiah 11:6-7, suppose that in a perfect world, animals only eat plants. But in fact, plants themselves depend on the bacterial decay of dead organisms. If animals didn't die, then essential nutrients would disappear from the ground, and plants could not continue to grow. Eventually, there would be nothing left for animals to eat, and all life would cease.¹¹

Miracles

Many Christians are uncomfortable with evolutionary theory because it denies a miraculous, supernatural origin of life. They fear that if those miracles are denied, it might lead people to reject the possibility of miracles altogether, including the central feature of the Christian faith—the resurrection of Jesus from the dead.

As a devout Christian, David Lack certainly affirmed the fundamental tenets of the gospel. But at the same time, he explained to his readers that invoking miracles to account for unusual features of the natural world is not particularly helpful when trying to deepen our understanding of God’s great multitude of creatures:

[The biologist's] research depends on repeated observations. It need not, as popularly supposed, consist solely, or even mainly of measurements and experiments, but unless events are repeated, they cannot be assessed by science. Hence truly unique events come outside the domain of science, though biologists are not usually convinced when told they must, therefore, leave such problems as miracles to others. For one of the chief ways in which research has advanced is through the discovery of apparent exceptions to the known rules, and if further study shows the exceptions to be replicable, new regularities are revealed from which modified rules can be propounded. This method has been so successful that the biologist tends to doubt whether there are any types of irregularity, or seeming irregularity, that will not yield to it.¹²

But just because a scientist cannot repeat a particular event doesn’t mean it didn’t happen. Both natural history and human history contain unique events that only happened once. As we peer into the past, the difficulty of discerning fact from fiction inspires us to further investigate the mysteries that surround us.

Conclusion

David Lack’s book Evolutionary Theory and Christian Belief was quite insightful, but his enduring achievements took place in evolutionary biology, a place where many Christians are afraid to tread. While it is significant that he himself found no contradiction between his faith and his science, perhaps the greatest testament to the compatibility between Christian faith and evolution is the life he led as a believer in both. As we saw in Ernst Mayr’s candid praise, Lack reflected the light of Christ through both his personal and his professional relationships.

Today, many voices in our culture still insist that evolution is incompatible with a sincere faith in Jesus, but a careful look at history demonstrates otherwise. In the future, perhaps more people of faith will have confidence to study biology knowing that one of the most iconic symbols of evolution—the Galapagos finches—owe their fame in large part to a devout Christian named David Lack.

In Part 1 of this essay I pointed out that metaphysical naturalism is not necessary nor inextricably tied to the practice of science, and that essentialism is only one of the historically-Christian ways to think about being human. As a case in point, we can identify the Patristic Fathers and Medieval Christian thinkers who discussed a relational alternative for understanding the nature or being of persons.¹ Roughly, the idea is that the three persons of the Trinity are what they are and who they are in virtue of their relationship with each other, not based on some intrinsic properties that ground their uniqueness as persons in the Godhead. That is to say that Father, Son and Spirit co-constitute each other, or are bound up together with enabling each other to be distinctly the persons that they are. Far from a static form of being and relationship, there is a dynamic interrelatedness in the Trinity. Father, Son and Spirit mutually constitute each other while enabling each other to be particularly who they are and engage creation and salvation in particular ways suited to who they are as persons. Father, Son and Spirit are being in community.

By analogy of relationship, humans are what we distinctly are in our being and personality in virtue of our relationship to God, creation and each other. Our involvements with others necessarily shape who we are as particular persons. The personal realm, then, is characterized by a dynamic relationality, as persons have ongoing mutually constituting influence on each other. This is part of the “dynamic order” of creation “that is summoned into being and directed towards its perfection by the free creativity of Father, Son and Holy Spirit. That orientation of being is, of course, distorted and delayed by sin and evil, and returns to its directedness only through the incarnation and the redeeming agency of the Spirit. But evil distorts the dynamic of being, does not take it away.”² Like the relationality of the persons of the Trinity, we are being in community.

We can also pursue the doctrine of creation as an alternative to essentialism, to see if it sheds any light on possibilities for what it means to be human in a non-reductionist sense.³ As other writers have been exploring in the Forum over the past few weeks, the biblical claim that humans are created in the image of God is important to the Christian of view of humankind. This may sound like jumping out of the frying pan into the fire, for there are both Christians and non-Christians who claim that if humans arose through evolutionary processes, then we cannot be made in God’s image. Nevertheless, it is worth exploring as a way of showing that there are strong alternatives to a strictly essentialist understanding of being human.

The Image of God

Over the centuries, the dominant view of humans as the imago Dei has been grounded in the idea that there is something distinctive about the creation of humans that both sets us apart from the rest of the animals and that marks us as unique kinds of creatures. Though we are clearly both distinctive and unique, does affirming the imago Dei require this kind of essentialism? On the one hand, Genesis 1:27 has often been interpreted as grounding humanity’s being in the divine image of God on Earth. On the other hand, recent discussions in human evolution have focused on several independent lines of evidence supporting the hypothesis of common ancestry among primates and humans: fossil evidence over the last 6 million years; homologies or anatomical similarities between humans and the primates; biogeographical distribution of supposed human ancestors; similarities in developmental biology between humans and primates; and several lines of genetic evidence favoring common ancestry. In addition, our current best understanding of the genetic diversity of humans is inconsistent with models that assume all humans descended from a single original pair of individuals. Instead, the current best data and models indicate the human ancestral population was never smaller than several thousand individuals.⁴

On the surface, then, what contemporary evolutionary science currently says on human origins appears to challenge cherished beliefs and understandings of many Christians. However, to understand what implications, if any, an evolutionary development of humans might have on the image of God, we first need to get clear on what it means to be the imago Dei, and that has to be settled theologically, not scientifically.

Historically, some of the most popular proposals for the imago Dei were rooted in human rationality, human freedom or human creativity because it was thought that humans alone among the animals possessed one or more of these qualities. There are two problems with this traditional line of thought. First, investigations since the early 18th century have progressively led to the conclusion that such qualities of humans mark a difference in degree rather than a difference in kind (e.g., brains of mammals and humans are anatomically homologous, dolphins, primates, and some species of birds exhibit degrees of rationality and creativity). The degree of difference may be significant, but a difference in kind is necessary for the traditional line of essentialist thought.

Second, if we look to the Incarnation for clues to the imago Dei we find that Jesus’s humanity is never depicted as exercising extraordinary powers of rationality, freedom, creativity, and so forth. Primarily, Jesus lived as an embodied person in relationship with the Father, other humans and creation as enabled by the work of the Holy Spirit. In other words, Jesus’ human life in Scripture indicates that the divine image is a special relationship, or form of relationality: to be in relationship with the Father as a created, embodied person; to be sustained or upheld in this relationship with the Father through the perfecting Spirit; and to be in relationship with other persons and all of creation.⁵ Moreover, this special relationship is also a vocation to mirror or reflect the glory, life and worship of God.⁶

If to be the image of God is to be sustained in a special relationship with the Father, each other and creation through the Spirit, then the imago Dei is not grounded in intrinsic qualities that particularly mark humans as distinct from the rest of the animals, as essentialism would have it. Christians can understand Genesis 1: 24-31 and 2: 4-5, as many of the Patristic Fathers did, as an account of our unity and connection with the rest of creation as well as of our special relationship with God and role in God’s kingdom. So if Father, Son and Spirit created human beings through evolutionary processes, we would have continuity and connection with all of creation while still being the imago Dei. Evolution does not threaten human specialness before God unless it is viewed as a replacement for divine creative activity (which, of course, is what Richard Dawkins, Jerry Coyne and Answers in Genesis all do repeatedly).

If evolution is broadly right as an account of the creation of all living things (an empirical matter), and if some form of essentialism is found to be consistent with such an account (a philosophical and biological matter), Christians would then have two options for how to understand what it means to be human. We can look for some stable, unique intrinsic features in virtue of which we are human; or we can look to the special Spirit-sustained relationship we have with God, creation and each other. Both are biblically consistent, though I judge understanding the imago Dei as special relationship to make better sense of the whole of the Bible, as well as our experience in the world.

In a Nutshell

The meaning of the “image of God” has been debated for centuries in the church. A common view is that the image of God refers to the human abilities that separate us from the animals. However, scientists have found that abilities like communication and rationality are also present in animals on a basic level. Plus, theologians do not see the image of God as human abilities. Some theologians see the image of God as our capacity for a relationship with God. Other theologians see it as our commission to represent God’s kingdom on earth. Both of these theological positions are consistent with scientific evidence. Whether God created humanity through a miracle or through evolution, God gave us our spiritual capacities and calls us to bear his image.

In Detail

The “image of God” is a key concept in Christian theology, foundational to Christian thinking about human identity, human significance, bioethics, and other topics. Many Christians see evolution as incompatible with the image of God. How could God’s image bearers have evolved from simpler life forms? Doesn’t image-bearing require miraculous creation of humans rather than shared ancestry with chimpanzees? And when in the evolutionary process did humans attain this image? These questions are tied to many other issues concerning human origins, including the soul, the Fall, and the historicity of Adam and Eve (see sidebars), but in this article we will focus specifically on the image of God.

See “How does the Fall fit with evolutionary history?” and “Were Adam and Eve historical figures?”

The phrase “image of God” does not appear many times in the Bible, but the importance of the concept is emphasized by its repetition in the creation account:

Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground.” So God created mankind in his own image, in the image of God he created them; male and female he created them. -- Genesis 1:26-27

From this text, it is clear that part of bearing God’s image is ruling over the animals. Genesis 9:5-6 reveals another aspect of image bearing: all human lifeblood is sacred because all humans are made in the image of God. The emphasis on Judeo-Christian thought on the sanctity of human life is derived in part from this passage. In the New Testament, the idea is expanded further as Christ is revealed as the true image of the invisible God (2 Corinthians 4:4, Colossians 1:15).

For centuries, theologians have discussed these and other passages, debating the meaning of the image of God (“imago Dei” in Latin). Being made in God’s likeness is not a matter of our physical appearance, because humans don’t all look the same. But to what does the image of God actually refer? Many ideas have been suggested over the centuries, producing a huge body of theological writing. While hard to summarize, we give a brief overview below of three common themes for the image of God. After developing this theological context, we’ll consider how these ideas intersect with evolution.

Image of God as our abilities

A common view is that the image of God refers to human abilities. When people talk of the things “that make us human,” they refer to abilities like reason and rationality, mathematics and language, laughter and emotions, caring and empathy, and cultural products like music and art. Often the motive is to distinguish humans from animals by showing that humans have unique abilities that make us special and superior to animals. Saint Augustine (354-430 A.D.) wrote something like this when he said “Man's excellence consists in the fact that God made him to His own image by giving him an intellectual soul, which raises him above the beasts of the field.”¹ Saint Thomas Aquinas (1225-1274 AD) also emphasized intellect and rationality in his discussion of image bearing.² But Augustine and Aquinas were not speaking of intellect as an aptitude for math or music; Aquinas instead writes of an “aptitude for understanding and loving God.” In fact, the modern emphasis on reason comes more from secular Enlightenment ideas than from Christian theology. During the Enlightenment, the image of God was connected to ideas like the natural dignity and majesty of humankind that separates us from the brute beasts of the animal world.

Scientific evidence is piling up that humans have more in common with animals than was once thought. Genetic evidence shows that humans and chimpanzees share much of their DNA. Studies of animal behavior (particularly of chimps and other apes) show that animals not only laugh and cry and care for each other, but can learn sign language and even have basic reasoning ability. In fact, Christian neuroscientist Malcolm Jeeves writes that “any attempt to set down a clear demarcation between the reasoning abilities of nonhuman primates and humans is found to have become blurred.”³ Obviously, humans have a much larger capacity to reason than animals, but reasoning is not a uniquely human ability. As neuroscientists and animal behaviorists learn more about animals, they see how traits appear in a rudimentary form at a level similar to human children.⁴ Whether or not one accepts evolution, evidence from living humans and animals does not show a distinct difference in kinds of abilities (only degree).

See “Made in the Image of God: The Theological Implications of Genomics” a 2-part blog by Denis Alexander.

Another challenge for this picture of the image of God is the place of people with mental disabilities. If a person is impaired in reasoning or language, are they bearing less of God’s image? Are they not showing his true likeness? The Christian answer to these questions is No! The Bible repeatedly teaches that God values all people, particularly those who are rejected by society or unable to care for themselves.⁵ In fact, Genesis 9:5-6 points to image bearing as the reason that all human life is valuable. This is a major motivator for Christians who seek to protect the unborn, the poor, and the aged. Surely bearing God’s image must mean something other than using our abilities.

As we’ve seen in recent essays (and comments) touching on Biblical scholarship, philosophy, theology, and anthropology, the imago Dei is a complicated idea, linked to the question of whether what makes humans unique among the creatures on earth is physical, cultural, spiritual, or some combination of all three. As Christians who seek to frame what the natural sciences tell us about our physical humanity with what the Bible suggests are our defining human qualities, we tend to focus on what Genesis means when it says Adam was “made in the likeness of God”; but it is helpful to remember that the first mention of God’s image in human form looked forward to the full revelation that would come in Christ. Thus, we ought also seek to understand Jesus as the model towards which Adam always pointed, and by which we should understand both Adam and ourselves.

Going one step further, we should also look forward from Jesus to the life of the Church. For if Jesus was the true image of God, then at Pentecost, the new community of believers took on the role of imaging the continuing presence of God in and for the world. The Church was constituted as the very Body of Christ, charged with making him known in their lives as well as their words. Thus in the structure and life of the Church we also see something important about the imago Dei.

Perhaps one way to hold in tension the various interpretations of the image—that is, to affirm the incomplete truths available through the relational, functional, substantial, and elective models—is to look at a literal image of the way the social aspect of imaging God via the Church interacts with the intensely individual and personal aspect of imaging God in individuals. Picking up on Kathy McReyolds’ sketch of personal transformation through encounters with those with disabilities (More than Skin Deep), I’d like to turn our attention towards the work of Chicago artist Tim Lowly, whose monumental portrait of his disabled daughter (Temma on Earth, 1999), is pictured above. Lowly’s work compels us to recognize the image of God even in one who lacks markers of those other roles, capacities, and relationships, and highlights two linked characteristics common to Jesus and Church: brokenness that does not merely equate with imperfection, and a social picture of our essential identity in Christ. By allowing Lowly to place Temma’s identity and humanity at the center of our attention, we can reframe our sense of what it means to bear the image of God and reflect the crucified Christ as his Body.

Profoundly Other

Born in North Carolina but spending his youth in South Korea (where his parents were Presbyterian missionaries), Tim Lowly attended Calvin College and began work as an artist in Michigan. But his life and work took an unexpected turn in 1985, when Tim and his wife Sherrie’s daughter was born and suffered a medical emergency during her first two days home from the hospital. In 2002, journalist Fred Camper’s incredibly sensitive article treated the Lowlys’ physical, emotional and spiritual journey with Temma at length, and I encourage readers to turn to that essay for the full narrative background to Tim’s approach to his daughter and his art. But the central facts are that for all of her now 27 years, Temma’s host of physical and mental disabilities have made her completely dependent on others, and have meant that the relationship she has with her parents (and they with her) is a radical departure from ‘normal.’ Temma’s “profound otherness” challenges most of our expectations about the human capacity to image God. Speaking to Camper, Lowly describes Temma:

It's unlikely that she thinks in a way that we would call thinking," he says, "because our ways of thinking are based so much on learning, experience, sight, socialization, and history, and I doubt any of those things have any bearing on Temma. I don't even think comparing her to animals makes sense. There's a certain wholeness to the way animals think that I don't think Temma is capable of. I'm pretty sure she does have an inner life, but I don't think she has the mental mechanisms that would make it correspond in an understandable way to the way we think.

And yet Lowly has produced hundreds of paintings and other works that feature Temma, some of them monumental in scale, none of them shying away from questions of the purpose, value, and meaning of her life for their family, and for ever-widening circles of community. Certainly there is a political component to Lowly’s work that addresses inequity in culture and church. Generally, he says, the church has been compassionate, but “nearly always from perspective of the able-bodied and the ‘whole’ vs. the disabled, never mind that none of us measure up to complete wholeness.” Yet his work also reflects the way Temma, in her “otherness,” creates community. Artist-in-residence and gallery director at Northpark University since the mid-1990s, Lowly has often made Temma a physical presence in the studio and classroom. Carry Me, 2002 (drawing on panel, 108" x 48," at left) depicts students from an advanced class holding Temma, but they were also involved completing the project. Another large work, Culture of Adoration, 2008, shows Temma as the model in a drawing class, with Lowly drawing the parallel between that scene and the adoration of the Magi at Jesus’ birth. That comparison pictures the way a community forms around loving attention and worship, but subverts artistic and cultural expectations that only what is beautiful should be valued. Lowly notes that while Temma is often alone, in some ways she’s never alone: “She’s cared for by her parents, but that relationship extends out to a much broader church outside her family.” Both paintings, then, are images of Christ’s corporate body as much as they are of Temma or the painting students who carry and draw her.

What bearing, then, does Lowly’s particular way of seeing and depicting his daughter have on us, on our sense of the imago Dei? Part of his ongoing artistic project is to understand and interrogate the way the traditions of perspective in Western art and culture presuppose and privilege the individual, solitary and unified point of view as the most important, the most true. In the wake of modernist emphases on self-expression in art, Lowly also sees value in pursuing ways of working that bring out the meditative (and even prayerful) craft aspect of painting, and that at least partially de-emphasize his and other artists’ subjective positions. He increasingly works from photographs (and collages of many individual pictures), and has more and more sought to bring collaboration into the making of his work. When Lowly takes Temma as his subject, these features of his practice emphasize the way that, in the Church, our individual identity is experienced as a tension between brokenness and wholeness in the Body.

Broken Together

There is a sense in which we look at Temma and we want to affirm that she is made in the image of God by denying that the image of God has anything to do with her physical, material body. Indeed, one way to approach the problem made visible through Lowly’s painting is to imagine the soul as imparted to (or trapped in) the physical frame. This certainly fits with saying that the image-bearing role of humanity in general is an act of the grace of God, not something dependent on our abilities. But in the election model, we are reminded that God didn’t call Abraham just to a “spiritual” identity, but also to physically constitute a people sent into the very concrete physical world.

Likewise, if we recognize Jesus as our model for the image of God, we will not deny the physicality of the human experience, nor the incarnation, nor even Christ's suffering on our account. Indeed, we must affirm the goodness of creation and our physicality, even—especially—in its brokenness because Jesus, himself, was broken. Even after the resurrection, his wounds were not abolished or erased, but remained tangible marks by which the Lord revealed himself every bit as much as he did in his creative and healing power. And in the Revelation image of the victorious Christ, we have another picture of that essential and persistent sacrificial brokenness in the Lamb who appeared “as if slain.”

What of the Church? Similarly, the Church remains a fragmented whole when it is at its best—broken open to be dispersed into the world. And though it is also all-too-often broken by own individual and corporate sin, even that finds its meaning and redemption in the image of bread broken in the Lord’s Supper—the way that sharing brokenness together unites the individuals in a congregation with each other and with Christ. As a reminder of Jesus’ own individual body, communion addresses both of those senses; it is the means of both healing and sending.

Christ’s commission to the Church, then, presents a profoundly social model of being the continuing revelation of God for the world. We bear the image of God together, and the image of God is only fully realized when we are members of a community, in relation to other human beings (even if that relationship is one of complete dependence), as opposed to seeking independence. This does not and ought not compromise the absolute worth of each individual, but should remind us that part of our worth is tied up in our integration with the whole body of Christ.

One last example of Lowly’s work gives iconic form to this inter-relation between image-bearing, self, identity, and the community of the Church. Made to commemorate Temma’s 25th birthday in 2010, At 25(right, and below), is a collaborative piece constructed of 25 individual, two-sided panel blocks that fit together something like a puzzle. On one side is a black and white portrait of Temma, while on the reverse, the individual blocks have been painted and gilded in different patterns and techniques. Lowly constructed the piece, but sent each block out to be completed by 30 different artists, either working alone or in pairs. In requesting them to do their sections of the composite portrait in an “artistically neutral” style, he was asking them to subjugate their artistic personae and self-expression to the depiction of Temma. Not every artist was able to do that to the same extent, so the final object is an image of the imperfection of our self-giving—or our inability to see others without looking through our own particular lenses of self—even while being a testament to the compassion and care of Lowly’s dispersed community.

Most importantly for this discussion, At 25 suggests that our image-bearing of God does not rest on our individual “fitness,” much less how well we “fit in.” Rather, it is carried by the whole human community, most fully in the broken Body of Christ. In this respect, brokenness is not something to be corrected; it is something that makes the particular community of the Church possible. Individuals may not be able to fulfill or even recognize the functional aspects of the imago Dei, they may not even be capable of the relational aspects—or of returning expressions of love or kindness or thanks, or even awareness. But the whole body, the beloved community, the nation God set apart for himself and the world, is called to be the image of God for each of us—precisely when we can’t.

Tim Lowly is Assistant Professor of Art at Northpark University. An inter-disciplinary artist, he works with painting, drawing, installation, digital media, photography and music: both individually and collaboratively. His work has a lyrical realism and quiet spirituality that have contributed over the last thirty years to the development of a international reputation. While Tim’s art and music address a variety of subjects, the central pillar of his work has been his daughter Temma who is, in his words, “profoundly other”. The clinical diagnoses of “multiple impairment” or “spastic quadriplegia” do little to address the compelling presence of this young woman and the way her being and essence have shaped her father’s work.

Lowly was born in Hendersonville, North Carolina in 1958. The son of medical missionaries, he spent most of his youth in South Korea. He attended Calvin College and received a BFA degree in 1981. His wife Sherrie Lowly is a United Methodist Pastor. They reside in Chicago, Illinois. Since 1994 Tim has been affiliated with North Park University in Chicago as professor, gallery director, and artist-in-residence. Tim is represented by Koplin Del Rio Gallery in Los Angeles.

For the past twelve years, I have had the privilege to teach in the Bible Department at a prestigious Christian university. Most of my students have been raised in Christian homes and have attended conservative, Bible-believing churches all of their lives. These students believe that they have a pretty solid understanding of what the image of God entails; at least they think they do until they encounter the world of disability. Disability creates a dissonance in their worldview that they are not expecting. All of a sudden, what they thought they understood about the image of God comes crashing down like a house of cards. The image of God and disability just do not seem to go together.

The following quotes from some of my student’s papers are representative of many and their experience with the disabled “strange other.” What is communicated loud and clear is the challenges disabilities raise for their conception of the image of God:¹

I believe that those with disabilities are equal to us … but I discovered a hidden evil in my heart. Deep in my heart, hidden from the world, I believed that children born with disabilities that would normally not survive its first few days should be allowed to die.

I think I could have intellectually acknowledged that all men and women are created in the image of God … In this class I was challenged to see the realities of disability and ask if I really did believe that God created these individuals in his image and salvation was for them too.

Though I have always known that these individuals are created in His own image, I often found myself secretly thinking that they were miserable and often a burden on others.

Sometimes I feel pity for disabled individuals because they are not “normal”. I feel that their disability is hindering them from experiencing the best life possible. I think disabled people experience a lesser quality of life because they cannot physically and/or mentally do as many things as a “normal” person could.

Now, these young people are not more spiritually or morally bankrupt than others in contemporary society. In fact, to the contrary, these Christian students are considerably more spiritually and morally sensitive in general because of their commitment as Christ- followers. Still, these views have been nurtured and influenced by two factors, one that is cultural and one that is religious: 1) the pervasiveness of a reductionist view of human being fostered by scientism; 2) a wooden, literal interpretation of Genesis 2:7 which says that “the Lord God formed the man from the dust of the ground and breathed into his nostrils the breath of life and the man became a living being.”

Taken together, these two factors present a skewed view of human being, one that focuses on the physical and material rather than on the spiritual and essential. This is one of the reasons why my students twinge and recoil a bit at the thought that persons with disabilities can be made in God’s image. “They just don’t look like it,” they say, zeroing in on what is physically seen. This view has had enormous consequences for people with disabilities. In fact, Adolf Hitler, as part of developing his approach to the weaker members of society in his book Mein Kampf, identifies the stronger (better looking and functioning) members of society as “images of the Lord” in contrast to the weaker members who are mere “deformities” of that image, and who ought to be cleansed from society. Many have argued that Hitler’s ideas concerning those with disabilities were inspired solely by Darwinian evolution. However, these quotes from Mein Kampf reveal a horrific misuse of Scripture, not evolutionary ideas.

Furthermore, with regard to evolution, a face value exegesis of Genesis 1 & 2 does not dictate that the physical stuff God used to create human beings was special or unique or that the image itself resides in it. It shows, rather, that all matter was formless and void until God, who acted and willed out of his good pleasure and sovereign choice, brought order and harmony to it. This applies as well to the creation of human beings who are uniquely created in God’s image. If this image is not merely physical stuff, what is it? What does the literary and historical context of Genesis 1 & 2 reveal?

There are three views on the image of God: 1) Substantial; 2) Relational; and 3) Functional. The functional view sees the imago Dei as a function or role that humans fulfill--such as being priests or having dominion. The relational view has to do with humans imaging God in their ability to have spiritual relationships—primarily with God, but also expressed in terms of our male and femaleness and other nuances. The substantial view essentially says that God’s image is imprinted on the person’s soul as an image is impressed on a coin, and has much to do with human capacities like our free will and ability to reason. It has been predominant in Christian theology in the West since about 600 AD.

But though we do have specific capacities that bear on our responses to God, as the substantial view says, the human being is an embodied soul who has both relational and functional capacities, as well. The relational implications include the biblical truth that among all God’s creatures, only human beings can know Him and be consciously aware of Him. Most importantly, he knows us and can be in relationship with us even when we do not acknowledge him out of rebellion, or cannot respond to him because of disability. If we consider the Substantial view’s emphasis on conscious awareness, ability to exercise freedom, and decision-making capacities alone, however, some human beings may not qualify as persons, whereas some non-human animals might.

Against this, a more holistic view affirms that all human beings bear God’s image, regardless of capacities. The image of God cannot be lost or compromised in anyway. Even the poorest functioning human being profoundly reflects God’s image.

In an unexpected and peculiar way, my students discovered this truth about the image of God when they began to interact with people with disabilities in my classroom. This truth about the image utterly transformed and they began to see people with disabilities quite differently. The following quotes come from the same students quoted at the beginning:

What I came to realize is that since the disabled are people, they deserve life. As humans made in the image of God, we are to try to preserve our fellow disabled brothers and sisters who are also made in the image of God.

When I went to the day group home, it was an amazing experience. I really enjoyed interacting with everyone there. I was able to paint with them, and one of them sang to me and taught me to dance; it was so much fun. It was great to see how each and every one of them was so unique and made in the image of God.

In this class I was challenged to see the realities of disability and ask if I really did believe that God created these individuals in his image and salvation was for them, too. As a result of what I have learned from this class my answer to these two questions is a resounding yes! God loves individuals with disabilities and knows the depths of their hearts and minds on a level I could never comprehend. Who am I to doubt who God knows, who He loves, and to whom He offers the gift of His Son.

At the beginning of the semester, disability was a foreign world for me. That world was new and uncomfortable. I had no idea how to interact with anyone with a profound disability and had little desire to learn how. Throughout this course, the walls of misconceptions, fears, and insecurities that I have built up to distance myself from disability have slowly been chipped away. As I learned more about disability, my fears and discomfort were replaced with compassion and joy. Exposure to individuals and families with disabilities was the most effective way to break down those walls. Having the opportunity to observe and interact with individuals with disabilities was invaluable. Participating in disability ministry is not burdensome, as I had initially worried, but freeing. I left the night feeling uplifted, loved, and so aware of God’s mysterious presence within broken humanity.

During Jesus’ ministry on earth, often the best way to find him was to seek out those society considered strange, unclean, or undesirable; Jesus often sought them out, himself, in order to show that God’s love for us does not depend on our merits or abilities, much less our outward appearance. Similarly, my students today meet the Lord anew—and discover that same message of God’s unmerited grace and love—when they seek out relationships with those our society finds strange and broken, with those who they could easily avoid seeing at all. Rather than judging with the eyes alone, my students learn to recognize their cultural and theological blind-spots, and see both the disabled and themselves in the light of Christ’s love. Relationships are transforming; and relationships with people with disabilities can transform not only our image of them, but of the God who made in His image, and dwells with us in places deeper than the skin.

The people of your culture cling with fanatical tenacity to the specialness of man. They want desperately to perceive a vast gulf between man and the rest of creation. - Ishmael ¹

For the destiny of humans and the destiny of animals is the same: As one dies, so dies the other; Both have the same breath of life. And humans have no preeminence over the animals…All go to the same place; All come from dust, And to dust all shall return. - Ecclesiastes 3:19-20

What is humankind’s place among the animals? Should we even count human beings among the animals at all? Perhaps we—as men and women—are something else entirely? Such questions are not new. Indeed, they are as old as writing itself and similar ponderings about human identity occupy the most ancient of texts. While many of these primeval writings have crumbled in the winds of time and have come to us only in fragments, the Genesis account of human and animal origins remains a living document that occupies a vital place in the life of Christian practice and thought. In the first chapter of the Genesis narrative we read that humans—male and female—were created in the image (tselem) and likeness (demuth) of God. But what does this mean? There is certainly no shortage of proposed answers, and over two thousand years of theological tradition bears witness to this fact. Here, however, we are not primarily interested in tradition—as valuable and insightful as it may be—but we are concerned with what the Bible itself has to say.

Taking the authority of Scripture seriously demands that we engage with Scripture in light of both its original languages and its original cultural context. If we are to avoid—as much as it is possible—projecting our own personal, modern and post-modern cultural presuppositions onto Scripture, then we must be willing to do some of the hermeneutical (or interpretive) hard work. In other words, if we want to allow Scripture to speak for itself, we must be hyper-aware of the cultural lenses we are wearing when we read it. Interpreting the Bible through five hundred years of Protestant tradition, fifteen hundred years of Roman Catholic tradition, or one hundred years of Seventh-Day Adventist tradition won’t do.² Rather we must venture to take off the thick hermeneutical lenses of tradition and boldly attempt to go into the world of the sacred text itself so that we can allow the ancient inspired words to shape the lenses or our reading.

With this approach to Scripture in mind, I believe it is useful to address the matter of the image and likeness of God (or imago Dei) by first asking what the imago Dei is not. Throughout the centuries, theologians, philosophers, and others have posed a number of answers to the question of what the imago Dei is. The vast majority of these answers have focused on one or a few characteristics that humans alone have and that non-human animals lack. For example, Evangelical Christian author Kay Warren explains: “Animals and people are two different classes of created beings and they will never be equal in their worth. As precious as animals are to our daily existence, they operate from instinct, not volition. Only people have a spiritual dimension. We are the ones created in the image of the Creator, the only ones with a soul.”³ In a similar manner, political commentator Ann Coulter, citing “the story of Genesis”, maintains: “It’s not merely opposable thumbs and a bipedal gait that make us distinct from the other beasts. It is consciousness of our mortality, a moral sense, language, mathematics, art, beauty, music, love, longings for immortality, a sense of symmetry, the soul’s ascent, the ability to accessorize, and our fascination with Branson, Missouri…We are in God’s image, and we’re the only ones in God’s image, which is why we eat escargot rather than worship them.”⁴ While these are two popular contemporary voices, similar views are espoused by numerous academics as well. In this way the imago Dei has, for many, become synonymous with one central characteristic or several key traits that make humans unique among and/or superior to animals.⁵

As intriguing as such perceived indicators of human uniqueness are, and regardless of the scientific status of claims for such distinguishing human traits, the idea that there are particular physical features and/or behavioral characteristics that make men—and not beasts—in the image and likeness of God is not one that is found anywhere in the pages of Holy Scripture. With regard to humans as “the image and likeness of God,” a literal and consistent reading of the Genesis narratives discloses that the imago Dei designation does not refer to unique characteristics or capacities which humans posses in a way that excludes other non-human animals.

Hebrew scholar Phyllis Bird informs us that the scriptural context of the phrase “image and likeness of God” makes it plain that “its theological significance is in the place it gives to humans within the created order, not in any physical or moral attribute of the species, in either its present or ‘original’ state.”⁶ In the Bible the imago Dei is not about exceptional human capacities or characteristics that automatically qualify humans as being included in the imago Dei category. There is no reason, explains Bible scholar James Barr, to believe that the author of Genesis chapter one “had in his mind any definite idea about the content or location of the image of God.”⁷ The terms “‘image’ and ‘likeness’…make no statements about the nature of human beings.”⁸ When we read of “the creation of human beings in God’s image (Gen 1:26)…the biblical narrative remains silent…about any qualities of human nature that might account for their special standing.”⁹

If we are to properly understand the meaning of the texts, then, says Old Testament scholar Claus Westermann, we must confidently resist “the tendency to see the image and likeness of God as a something, a quality.”¹⁰ Consequently, a literal reading of the early Genesis accounts demands that no specific anthropological content or characteristics may be directly equated with the imago Dei. If one is to take the findings of biblical exegesis seriously, then—apart from theological tradition—the image of God cannot be defined on the basis of particular physical traits or behavioral characteristics. This means that—according to a straightforward reading of Genesis and the rest of Scripture—humans are not said to be biologically or behaviorally unique in a way that is related to their being named the “image of God.”

In addition to the broad consensus among biblical scholars that the image of God in humans, when understood within its original Hebrew linguistic and Ancient Near Eastern context, has nothing whatsoever to do with an appeal to the human possession of particular characteristics which non-human animals lack, research in biblical exegesis has similarly revealed that there is no essential or substantial super-natural divide between humans and other animals. Scripture, when read in the original languages, clearly describes both “man and beast” as possessing “the breath of life” and refers to both equally as “souls.” In this way Scripture makes no ontological or metaphysical distinctions between humans and non-human animals. Instead, the scriptural “emphasis lies on the commonality that exists between the humans and the rest of the animal creation.”¹¹

While the use of the Hebrew word nephesh, often translated as “soul”, to describe humans has been taken by some as an indication that humans are substantially set apart from the animals, the nephesh is not an exclusive possession of humans. Indeed, the Hebrew text describes both humans (Gen 2:7) and animals (Gen 1:21, 24) equally as nephesh hayyah or “living souls.”¹² Thus, Bible Scholar Gordon Wenham explains that in Genesis 2:7, which describes the human being as a nephesh, “it is not man’s possession of the ‘breath of life’ or his status as a ‘living creature’ that differentiates him from the animals—animals are described in exactly the same terms.”¹³ In Genesis, “human beings…are only one subset of God’s ‘living beings,’ into whom God has breathed the breath of life” and established as “living souls.”¹⁴

According to the biblical understanding, then, “what is distinctive about human beings is not that they have a ‘soul’ which animals do not possess, nor that they have a ‘spirit’ which other creatures do not possess.”¹⁵ It is clear, then, that “the possession of nepheš is not a unique characteristic of the human person.” Indeed, “unless one is ready to grant that animals have ‘souls’ in the same way that humans are alleged to have, then we might better conclude that the Genesis account is referring to the divine gift of life: ‘the human being became a living person.’”¹⁶ Consequently, “claims for a ‘special creation’ of humanity in comparison with animals and the material world conflict with the strong assertion in Genesis 2 that, physically (organically), Adam does not differ from the ‘beasts of the field.’”¹⁷ The theological language of anthropology in Genesis 1 and 2 “underscores Adam’s linkage with the animal creation, not his difference from it.”¹⁸

Whatever else the imago Dei might be, then, a clear and consistent reading of Scripture does not permit us to equate it with either a non-material soul which animals lack or some unique physical characteristic or behavior which animals lack. These conclusions regarding what the image and likeness of God in humans IS NOT lead us directly to our discussion of what the imago Dei IS.

In Part 2 of this series, Dr. Moritz examines how the phrase "image and likeness of God" is used within Scripture itself.

I want to express my gratitude to those associated with BioLogos for the chance to dialogue with them. I have found their material to be challenging and thought provoking, and look forward to continuing the conversation. In the area of science, to call me a novice would be a kindness, and so to question their evaluation of the scientific evidence for the evolutionary process would be inappropriate for me. However, I do want to raise some questions about their evaluation of theological issues, especially concerning the image of God in humanity. I refer especially to their response to the question, “At what point in the evolutionary process did humans attain the ‘Image of God?’”¹

The BioLogos response begins by correctly noting that the precise meaning of the image of God has been the subject of debate throughout Christian history, but they believe the majority view sees the image of God as “characteristics of the mind and soul,” such as “the ability to love selflessly; engage in meaningful relationships; exercise rationality; maintain dominion over the Earth; and embrace moral responsibility.” They see these characteristics as being acquired through the evolutionary process, though they also state, “We do not know if humanity received the image of God by the immediate onset of a relationship with God or by a slower evolutionary process.” Further, since they identify the image with characteristics of the soul, they add in a discussion of the soul, “We also cannot know whether God directly intervened in the evolutionary process at this point [referencing Gen. 2:7], or whether the unfolding evolutionary process produced the human soul.” It is at this point I wish to question whether or not it is possible for the image of God to be produced through the evolutionary process apart from the special intervention of God. BioLogos seems to lean toward the image being produced through evolution, but is ultimately non-committal on the possibility of divine intervention. I want to argue that there is good reason to argue for the necessity of divine intervention in giving to humans the image of God.

I have no strong objection to the list of characteristics given in the BioLogos response, though I would see most of them as underlying the capacity for relationship with God, which I see as central to the image. Nor do I have any necessary objection to the idea that God used the evolutionary process in developing the brain and other physical abilities of human beings necessary for exercising some of the characteristics involved in the image. Nor do I think that Gen. 2:7 requires the direct intervention of God in implanting the soul (though it certainly allows it). The problem, rather, is in not recognizing that the image of God in Scripture seems rather clearly linked with something immaterial in the human constitution (whether it is called soul or spirit) that could not have come into being by evolutionary processes. My argument for affirming the necessity of direct intervention of God in the creation of humanity in the image of God rests on three assertions. Let me try to state and defend them.

First is the assertion that central to the image of God is the capacity for relationship with God. I do not think this would be rejected by those in the BioLogos community. Within the BioLogos response the phrase “relationship with God” is found numerous times in association with the image of God. They may not like the part about such a capacity being central to the image of God, but the fact that the image of God is what distinguishes humans from other animals in Genesis 1, coupled with the fact that it is humans, and not other animals, who engage in personal relationship with God throughout Scripture, makes a fairly strong case for linking “image of God” to “capacity for relationship with God.”

The second assertion is that this capacity for relationship with God is something that continues after the death of the body, and is associated with something in human beings that continues to exist after the death of the body. Here I recognize that there has been a growing chorus of voices advocating monistic views of the human constitution,² but they all seem to fail to account for the strong biblical evidence for human existence in the intermediate state.³ That which survives death is called the soul in some places (Gen. 35:18; Rev. 6:9-10) and the spirit in others (Eccles. 12:7; Heb. 12:23), but it is identified with the person himself in II Cor. 5:8 and Phil. 1:23. Jesus says to the thief on the cross, “Today, you will be with me in paradise” (Luke 23:43). Both of their bodies would soon be in graves, but the words “you” and “me” seem to affirm an existence apart from their bodies.

The third assertion is that whatever it is in human nature that survives the death of the body (soul or spirit) must be non-material, and could not be produced by the evolutionary process.⁴ Alvin Plantinga, in an argument against materialism, asks, “How could an immaterial soul have come to be by way of evolutionary processes?”⁵ He quotes Richard Dawkins,

Catholic morality demands the presence of a great gulf between Homo Sapiens and the rest of the animal kingdom. Such a gulf is fundamentally anti-evolutionary [and hence wholly heretical?]. The sudden injection of an immortal soul in the timeline is an anti-evolutionary intrusion into the domain of science.⁶

I would change Dawkins’ wording from “Catholic morality” to “The image of God in humans” but the conclusion is the same. I cannot imagine how an immaterial reality, which survives the death of the body, could be produced by natural processes, such as evolution, even God-guided evolution. I do not think this is a God-of-the-gaps argument that could eventually fall to advances in science, but a logical argument, based on the intrinsic difficulty of seeing how the natural and mortal could produce something immaterial and capable of surviving the death of the body. Even if someone were to question my association of the image of God with the spirit or soul (assertion 1), I would argue that the mere existence of an immaterial spirit/soul that survives death (assertion 2) yields the same necessity of divine involvement in the creation of the immaterial aspect of human nature (assertion 3), which is my chief contention.

Author's Note

I am so thankful that I grew up in a Christian environment, which both kindled and nurtured my relationship with Jesus Christ. The Biblical instruction I received from my parents, pastors, and teachers has been invaluable as I walk out my love for the Lord from day to day. However, there was one specific topic growing up which was not fully addressed, namely evolutionary theory.

Coming from a conservative Christian background, evolution was given little or no thought because of its seeming contradiction to the creation story in Genesis. To me, evolution meant a monkey became a human, and as far as I knew, I had never seen that happen! So, of course, it appeared too improbable to hold any truth. When it was discussed, an inadequate picture of its ideas was often painted, which caused immediate suspicion and rejection of the theory. I don’t think this was intentional, but most Christians have never learned an unbiased, in-depth theory of evolution that is completely detached from societal agendas and philosophical conclusions. Therefore, their explanations of the theory are often misinformed.

My senior year of high school, I took AP Biology, and finally learned the scientific reasoning supporting this theory. I was surprised by how logical and obvious the mechanisms of change (such as mutations, natural selection, genetic drift, and so on) were that gave rise to new species. My subsequent response was, “No wonder people believe evolution occurred.” At that point, I was convinced that microevolution (evolution within a species) existed, but I was still questioning macroevolution.

Now, being at Point Loma Nazarene University as an undergrad in the Biology-Chemistry major and a year-round, student intern at BioLogos, my understanding of evolution has expanded enormously. I have enjoyed critically thinking through the evidence for evolution and reading articles that tackle difficult issues at the interface of science and Christian faith. Ultimately, I know that God has created all things, but the processes he used surpass my small understanding.

My personal wrestling with evolution and quest for truth has led to times of prayer and studying God’s Word, which has deepened my love for him in ways I cannot express. The first chapters of Genesis, in particular, have come alive. My whole life, the creation story was a straightforward list of facts about the creation of the world; I never searched further. I didn’t even perceive the truths Genesis declared over my very identity and God’s character. The more I study his Word and handiwork, I glimpse the awesomeness and majesty of the Creator, who loves me much more than I know. There is still so much to learn, but I am confident that he will lead me into all truth as I seek him out.

I desire to give others the opportunity to see evolution accurately and to distinguish it from the traditional, philosophical, and personal conclusions that too often cloud the scientific theory. I believe these conclusions alienate Christians from evolution more than the scientific theory itself. Ultimately, I do not mean to convince someone about evolution, but simply to give them the freedom to understand it.

Therefore, my goal for this podcast is two-fold:

• First, to offer a new perspective on randomness within natural processes that removes its negative connotations (especially as it relates to evolution).
• Second, to expose why evolution is powerless to support conclusions beyond the physical realm.

This will hopefully encourage others to study evolutionary theory and draw their own conclusions about its meaning in the framework of their faith.

Many of the games I enjoyed playing involve a combination of strategy and randomness: card games of various sorts, backgammon, and board games like Monopoly and Parcheesi. Some games that rely exclusively on chance (like War and Candy Land) or too heavily on chance (like Sorry) quickly became uninteresting to me. In fact, for Sorry, War, and several other games, I introduced additional rules to change the balance of strategy and luck—for example, by allowing each player to hold a hand of cards rather than merely flip a card and follow its bidding.

When my children were young, I played many games with them, especially those involving some amount of chance. I always play to win, so games of pure strategy like chess gave me too great an advantage—at least when they were still young. I still remember the first time I played the German game Mitternachtspartie with my children and some of their cousins. The game uses a die on which the number 5 has been replaced with the image of Hugo the ghost. Each player rolls the die and moves one of his figures the specified number of squares, unless Hugo is rolled, in which case Hugo moves instead.

I quickly worked out the expected distance Hugo would move for each of my turns and the expected number of squares I would get to move my own figures each turn. Using that information, I could strategically place my figures in the opening portion of the game. I fully expected to win this first game, since my young children were going to have to learn from experience what I already knew by the mathematics of probability. I lost—badly. As it turned out, the die had two Hugos on it. So compared to my expectations, Hugo moved twice as often, and my figures moved slightly less far. That combination turned the carefully calculated positioning of my figures into a disaster.

From Fun and Games to Science

I still enjoy playing games, including games that involve chance. But these days I encounter randomness even more often in my profession. I was trained as a mathematician and now work at the intersection of mathematics, statistics, and computer science. Like many scientists, I use randomness on a daily basis as part of our toolkit for modeling and investigating all sorts of phenomena. Models known as stochastic models, which explicitly incorporate random components, often via simulation in computer software, are used to model everything from diffusion to genetics to quantum mechanics. Insurance companies and financial institutions use stochastic models to manage risk. If we include all the applications of statistics, then almost no area of science is untouched by the use of randomness.

Most of the time, scientists and game players alike don’t devote much thought to just what makes randomness tick. But they both know that the better they understand the probabilities, the more successful they are. Nevertheless, if you ask many of them what it means for something to be random, they may struggle to put it into words. I won’t try to give a precise definition either, but it is important that we have some idea what we are talking about, so let’s consider one of the prototypical examples of randomness: the tossing of a fair coin.

If I flip a coin, the result could be heads or tails. Until I flip the coin, I don’t know which it will be. In this sense, the coin toss is unpredictable. If the coin is fair, each result is equally likely, so while I cannot say in advance whether a particular result will be heads or tails, I can say something about a large number of flips: approximately half should be heads and the other half tails.

A little mathematics even allows me to determine a range around 50% in which the percentage will almost surely lie. For example, if I flip a fair coin 1,000 times, the percentage of heads will most likely be between 45% and 55% (where “most likely” means a 99% chance). If the percentage of heads lies outside this range—especially if it is quite far outside this range—I am going to be suspicious that the coin flipping process is not fair. That’s one of the key ideas in statistics: not only can we calculate the frequency with which an event occurs, but we can compare data to a stochastic model to see if they are compatible or incompatible.

There are several interesting things we can learn by considering a coin toss. First, probability calculations rely on assumptions. If the assumptions are incorrect, then the probability calculations will also be incorrect. For example, if the coin is biased (such as one that is heads 60% of the time), but we assume it is fair, then the probability calculations given above will be wrong. Of course, if the assumptions are not too far from correct, the results may still be sufficiently accurate for scientific conclusions. If we have an appropriate way to collect data, then we can test our assumptions by comparing data to projections made based on the assumptions.

Second, “random” does not imply “equally likely.” A fair coin should have equal probabilities of heads or tails, but a biased coin is no less random. It’s just different. It is not as simple to handle arithmetically as a situation in which all outcomes are equally likely, but it is not otherwise special. It is a common mistake to assume random events are equally likely when they are not (or when that assumption is not justified).

Third, randomness is about the process. It is a fun experiment to flip a penny 100 times, then spin a penny 100 times and record the side that is showing when it finally tips over, then to stand the penny on end (this takes a steady hand and a little practice) and record which side is showing after pounding the table. These are three different processes, and they do not yield the same results.

Fourth, random processes produce patterns. I sometimes ask my students to mentally flip a coin and record the results as a sequence of letters (e.g., “HTTHHTHT”). Then I have them actually flip a coin and record the results. If the sequences are long enough, I can almost always tell them which is which. The sequences imagined by the students tend to have too few runs of consecutive heads or tails. The sequences based on real coin flips usually include several heads in a row. People not familiar with randomness are often surprised at the patterns that result and assume that the process must not have been random when they perceive a pattern. Our eyes and minds are drawn to similarities and patterns—even those that are produced purely randomly. This can lead us to draw false conclusions from coincidences of all sorts.

Consider the image in Figure 1. It was constructed using a computer to randomly throw 300 darts at a square board. Every position on the board was equally likely to be hit by a dart. This does not, however, mean that the dots are evenly spaced. There are 100 smaller squares. The average is three dots per square. But your eye is likely drawn to some clusters and voids. My eye also catches a graceful downward swoop in the lower part of the upper left quarter. All of this is exactly what we should expect from this random process. If we repeated this experiment, we should expect similar results. Several of the smaller squares would be empty and some others would have two or three times the average number of dots, but these clusters and voids would appear in different places.

Finally, randomness can be used to produce patterns intentionally. Consider the two pictures in Figure 2. You may think the two pictures are identical, but they are not. However, they were each constructed using the same random process:

1. Start at the lower left corner of the big triangle.
2. Randomly choose one of the three corners of the big triangle.
3. Move half way to that corner, placing a dot at the new location.
4. Repeat steps 2 and 3, 50,000 times.

The first few steps of this process for each image are illustrated in Figure 3. Although the final images look very similar, the route taken to get there is very different. In fact, the only point the two images have in common is the starting point. As the creator of the program that generated these images, I knew full well that the result would resemble a fractal image known to mathematicians as Sierpinski’s Triangle, even though I did not know or exercise any control over how the individual points would be selected.

Despite our familiarity with children’s games and the importance of stochastic models throughout the sciences, many Christians have a reaction to randomness that falls somewhere between uneasy and antagonistic. And yet, those same Christians may well watch the evening news to learn about public opinion polls forecasting upcoming elections, take prescription drugs approved by the FDA based on statistics found in clinical trials, obtain electrical power from a nuclear power plant that uses random fission reactions, and insure their cars with companies that rely on stochastic models to set the rates. The foundation of each of these activities is a thorough understanding of randomness that begins with the simple description above.

So where does the uneasiness come from? Likely it comes from the feeling that taking randomness seriously means not taking God seriously. Or put more strongly, it comes from a fear that believing in randomness means not believing in God. Next week we’ll address that problem by asking the question, “Could God use randomness to achieve his purposes?”

In the 1950s, Cage began using various methods of “casting lots” to determine how elements of his music would be chosen and arranged—principally the Chinese system of I Ching. His controversial program was to distance himself from his own creative process, and he explored many additional strategies to transform the role of “creator” into one of “observer.” Most famous of these was his musical composition, “4.33,” which consisted of a pianist sitting at the instrument doing nothing at all for four minutes and thirty-three seconds, while musician and audience listened to the ambient sounds of the concert hall. Yet contrary to that main thrust of Cage’s work, a description of the activities during the week-long residency at the Mountain Lake Workshop where the New River Watercolor Series were made suggests that choice, constraint, and intention were integral and inescapable tools in putting randomness to work for creative ends.

Here’s art historian and theorist Howard Risatti’s description of Cage’s plan of action for the New River Watercolors, from the website of artist Ray Kass, who runs the Mountain Lake program and was Cage’s collaborator for his work there:

Following upon [a previous (1983) Mountain Lake workshop] “painting experiment,” stones collected from the New River were sorted into three groups according to size, which were separately numbered; numerous and varied brushes were divided into two separately numbered groups; likewise, feathers to paint with, colors and washes, and papers were also divided and numbered. In this way, chance procedures using pages of random numbers that were now generated by a computer program could be used to determine the specific materials utilized for each painting (e.g., which painting instruments, what type of paper and which colors, how many washes, which stones to paint around, where to locate the stones on the paper).

While this list enumerates all the specific variables that Cage and his team submitted to chance, there was an incredible level of personal engagement with the materials: Cage didn’t just show us drawings of where the I Ching said the rocks ought to be, he (or his assistants) placed them on the paper and used them as guides to paint around. Large custom brushes were constructed to lay on washes of color, and even the paints were hand mixed, combined, and diluted according to his desires.

Cage’s use of chance, then, was not a “hands off” process, but neither was it a matter of total control: Cage selected processes to create a space of play between himself and the materials he used: the feather between himself and the paper, for instance, introduced variability of resistance and spring, its ability to hold paint, the width of the line. All of these things were elements of material ‘freedom,’ areas in which Cage asked the stuff he used to make the paintings to take part in the process—to contribute its own identity to the intentional, purposeful, and determined work of creating “based on chance.” This should not be surprising, as all art, all creation that we can observe, happens as a dialectic between materials and the creator, and such engagement and interaction in no way lessons the purpose of making, the end in sight.

Kass’ book The Sight of Silence: John Cage’s Complete Watercolors, gives a much more complete account of the tools, processes, and interpersonal reactions between Cage, Kass, and the team of student assistants who helped at almost every stage of the creation of the works. The book goes to great length to honor Cage’s ideal of being present in but not controlling the outcomes (not least by nearly always putting words like “choice” in quotation marks), but the description of his process makes the centrality of Cage’s personal aesthetic and artistic motives inescapable, even more than his physical engagement. What comes through perhaps even more than the way Cage intended to allow chance to ‘guide the creative process’ is that way Cage, himself, not only set the parameters of the chance he allowed into the system, not only engaged directly with the materials during the process, but also exercised judgment over the results, both in process and at the end:

“Cage decided he didn’t want the images of the stones to overlap or go off the sides of the paper. To guarantee this restriction, he created conditions and rules to limit their possible placements.” (p. 51)

“For this single painting [Series IV, #1, pictured above] Cage chose to confine the images of the rocks to a lower area of the paper that represented the proportion of the “golden rectangle. . .” (p. 57)

“While “choice” established much of the work’s nature, “chance” highlighted the intrinsic nature of the materials to reveal a refreshing presence.” (p. 59)

“[H]e initially decided to remove [the first painting of Series III] from the group, and then, liking it more, changed his mind and returned it to the group that would be signed.” (p. 56)

This last note is particularly interesting in that it highlights the fact that Cage was claiming these paintings, naming himself as their author, and was attentive to which ones he approved of enough to call his own. There is no way around the fact that Cage was subjectively as well as objectively the maker of these works: the author of the procedures by which they came to be, but well as the judge (and sometimes redeemer) of the results. For Cage, randomness was a tool, no different than the brushes or rocks or paints is that its specific parameters were chosen at the outset, and always used within the context of his over-arching vision. Perhaps we may likewise think of God’s use of chance—constrained by and tuned to the material conditions he established at the birth of the cosmos—as a way to both engage with and allow freedom for the creation itself.

With any work of art it is reasonable to ask, “Is it beautiful?” or more tellingly, “Would I hang this on my wall?” Seeing Cage’s watercolors for first time without any knowledge of the process or the relative fame of Cage himself, some might be intrigued by the structure of the work (the proportions of the golden rectangle, the overlapping stone shapes, the colors of the paint) while others would be completely uninterested, perhaps even after hearing about how they were made and seeing them in the context of the rest of the New River Watercolor series. But if you had been there in the shop as an assistant, or even observer, if you had been party to the relationships that developed even over the few days Cage spent at the Mountain Lake Workshop, your sense of the beauty of these paintings (and perhaps even scraps of paper Cage used to try out brushes or washes), would take on a different meaning, in much the way we treasure the crayon drawings of our children not because they are spectacular art, but because they are tokens of our relationship.

I make that observation to emphasize one other aspect of Cage’s creative process: that Cage was the instigator first and foremost of relationships of creation. His process created not only paintings but the fellowship that developed as the work was being done. That social, interpersonal dimension is what gives the objects a depth of meaning beyond their material composition, and suggests the particular roles humanity has been given by God. One role is to join into the creative process as lesser, but not unimportant co-creators with him; the other is to observe, recognize and celebrate his activity in the world. Where some will see randomness as evidence of an absent God, our knowledge of this most personal and participatory aspect of creation points us to the God who is with us.

With God’s creation as with human art, we may (or may not) marvel at any one particular “work,” or even think the specifics of how it was made are interesting or attractive; but knowledge of and fellowship with the artist transforms our appreciation of the process as well as its results. When we know the maker, we come to recognize and treasure even the most “random” bits of his handiwork, and name them as his, nonetheless.

]]> Sun, 13 May 12 12:53:04 -0700 Mark Sprinkle http://biologos.org/blog/fearful-symmetries?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication http://biologos.org/blog/fearful-symmetries?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication Perusing the writings of atheistic scientists and philosophers like Daniel Dennett, one could easily get the impression that arriving at a simpler explanation for something equates to a revelation that things are “lower, cruder, and more trivial.” In his essay Fearful Symmetries, published in the October 2010 issue of the journal First Things, physicist Stephen Barr offered a critique of the modern tendency to make the investigative strategy of reductionism into a “metaphysical prejudice.” It is a mistake, he says, to take the extraordinary success of the scientific practice of looking at things in smaller and simpler parts as proof that “the further we push toward a more basic understanding of things, the more we are immersed in meaningless, brutish bits of matter.”

Perusing the writings of atheistic scientists and philosophers like Daniel Dennett, one could easily get the impression that arriving at a simpler explanation for something equates to a revelation that things are “lower, cruder, and more trivial.” But at the heart of Barr’s critique is the observation that in fundamental physics and advanced mathematics, “simpler” does not mean more chaotic and inchoate, but rather more elegant and beautiful. Those who hold to a philosophical reductionism “overlook the hidden forces and principles” that govern the processes of cosmic evolution.

Barr’s article lays out the way that the work of scientists and mathematicians exploring the fundamental principles of physics (from Kepler to Einstein to those currently running the Large Hadron Collider in Switzerland) actually suggests “that order does not really emerge from chaos, as we might naively assume; it always emerges from greater and more impressive order already present at a deeper level.” This excerpt gives his first example, the starting point from which he guides us into strangely beautiful world of particle physics, and towards the discovery that “matter, although mindless itself, is the product of a Mind of infinite profundity and infinite simplicity.”

Fearful Symmetries

“Let’s start with a simple but instructive example of how order can appear to emerge spontaneously from mere chaos through the operation of natural forces. Imagine a large number of identical marbles rolling around randomly in a shoe box. If the box is tilted, all the marbles will roll down into a corner and arrange themselves into what is called the “hexagonal closest packing” pattern. (This is the same pattern one sees in oranges stacked on a fruit stand or in cells in a beehive.) This orderly structure emerges as the result of blind physical forces and mathematical laws. There is no hand arranging it. Physics requires the marbles to lower their gravitational potential energy as much as possible by squeezing down into the corner, which leads to the geometry of hexagonal packing.

At this point it seems as though order has indeed sprung from mere chaos. To see why this is wrong, however, consider a genuinely chaotic situation: a typical teenager’s bedroom. Imagine a huge jack tilting the bedroom so that everything in it slides into a corner. The result would not be an orderly pattern but instead a jumbled heap of lamps, furniture, books, clothing, and what have you.

Why the difference? Part of the answer is that, unlike the objects in the bedroom, the marbles in the box all have the same size and shape. But there’s more to it. Put a number of spoons of the same size and shape into a box and tilt it, and the result will be a jumbled heap. Marbles differ from spoons because their shape is spherical. When spoons tumble into a corner, they end up pointing every which way, but marbles don’t point every which way, because no matter which way a sphere is turned it looks exactly the same.

These two crucial features of the marbles—having the same shape and having a spherical shape—should be understood as principles of order that are already present in the supposedly chaotic situation before the box was tilted. In fact, the more we reduce to deeper explanations, the higher we go. This is because, in a sense that can be made mathematically precise, the preexisting order inherent in the marbles is greater than the order that emerges after the marbles arrange themselves. This requires some explanation.

Both the preexisting order and the order that emerges involve symmetry, a concept of central importance in modern physics, as we’ll see. Mathematicians and physicists have a peculiar way of thinking about symmetry: A symmetry is something that is done. For example, if one rotates a square by 90 degrees, it looks the same, so rotating by 90 degrees is said to be a symmetry of the square. So is rotating by 180 degrees, 270 degrees, or a full 360 degrees. A square thus has exactly four symmetries.

Not surprisingly, the hexagonal pattern the marbles form has six symmetries (rotating by any multiple of 60 degrees: 60, 120, 180, 240, 300, and 360 degrees). A sphere, on the other hand, has an infinite number of symmetries—doubly infinite, in fact, since rotating a sphere by any angle about any axis leaves it looking the same. And, what’s more, the symmetries of a sphere include all the symmetries of a hexagon.

If we think this way about symmetry, careful analysis shows that, when marbles arrange themselves into the hexagonal pattern, just six of the infinite number of symmetries in the shape of the marbles are ex-pressed or manifested in their final arrangement. The rest of the symmetries are said, in the jargon of physics, to be spontaneously broken. So, in the simple example of marbles in a tilted box, we can see that symmetry isn’t popping out of nowhere. It is being distilled out of a greater symmetry already present within the spherical shape of the marbles.”

In the full essay, Barr gives a richer description of how this most basic kind of symmetry is just one sort of order, and how even this form points to other much more complex kinds of symmetry whose properties may be described only through the tools of complex mathematics. As he says, “the symmetries that characterize the deepest laws of physics are mathematically richer and stranger than the ones we encounter in everyday life.” But even more important than the fact that such mathematical concepts exist and are beautiful, more important even than the way such esoteric mathematical symmetries have suggested imminently practical experimental projects, is the way they point to a universe that is anything but brutish and trivial, though its elegance may be hard to see:

“It is true that the cosmos was at one point a swirling mass of gas and dust out of which has come the extraordinary complexity of life as we experience it. Yet, at every moment in this process of development, a greater and more impressive order operates within—an order that did not develop but was there from the beginning. In the upper world, mind, thought, and ideas make their appearance as fruit on the topmost branches of an evolutionary tree. Below the surface, we see the taproots of reality, the fundamental laws of physics that shimmer with ideas of profound simplicity.”

In today's video, Kerry Fulcher discusses the idea of viewing creation as a constant, evolving process in which God is intricately involved, rather than a single explosion of creation a long time ago. When we get stuck on the idea of having biological ancestors, Fulcher says, we can miss the point that being made in the image of God is a relational quality, not a biological trait. It means that we can communicate and have a special relationship with God, and we can reflect his character and represent him to the rest of creation.

In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris. Gould believed (and wrote in his book Wonderful Life) that if the "tape" of evolution were rerun, the chance that anything like human intelligence would emerge is essentially zero. In other words, humanity is here through random accident. Gould pointed to the work of Morris and fellow scientists in their research of the Burgess Shale as evidence for this view.

However, Morris himself disagrees, pointing to what is called evolutionary convergence. As Morris notes, there are numerous examples of identical features evolving multiple times throughout the history of life independently. Morris believes that if the tape of life were replayed, we would see something like humans emerge. A Christian might say, it looks like we were planned.

Some Christians might find Simon Conway Morris' viewpoint, with its implicit teleology, more attractive. Others, perhaps motivated by a high view of providence, may find Gould's emphasis on contingency equally congenial to their faith. What do you think?

"Reply the tape a million times ... and I doubt that anything like Homo sapiens would ever evolve again" (Stephen Jay Gould from "Wonderful Life", 1989 p. 289, Harvard University Press.).

With his standard panache, the late Harvard paleontologist Stephen J. Gould argued strenuously that evolution had no inherent directionality. It was a cosmic crapshoot - in no way destined to produce anything complex, self-conscious or human. We are mere accidents; a "tiny twig on an improbable branch of a contingent limb on a fortunate tree" ("Wonderful Life" p. 291). Highly fortunate indeed! Eons ago, a dinosaur-dominated earth held little promise for mammalian ascendancy (let alone primates or humans). Our distant ancestors might have remained little more than scurrying nuisances nipping at the feet of giants if not for a most unlikely calamity - a massive meteor strike which swept away the dinos and forever altered the earth's bio-saga. Who would have guessed?

Evolution's capricious nature seemed to represent a severe stumbling block for the Abrahamaic religious traditions. In their narrative, humans represented the culmination of God's creative work - the very purpose for creation itself. But evolution is an awfully shoddy way of enacting a divine plan. Gould delighted in annoying the faithful by emphasizing this very point:

"Odd arrangements and funny solutions are the proof of evolution - paths that a sensible God would never tread but that a natural process, constrained by history, follows perforce" ("The Panda's Thumb", 1980, pp. 20-1).

Theologians, however, were quick to point out that the chance element in evolution was neither new nor necessarily contrary to the Judeo-Christian view of God. Human history was replete with chance; evolution only extended the theme. Moreover, chance allowed for freedom - a virtue high on God's agenda. However theologically sound these retorts may have been, their force was often lost on the average believer. The accidental nature of human existence provided just another reason to reject evolution altogether in order to preserve God's special concern for humanity.

Gould was a talented science writer, but he overplayed evolution's whimsy. Increasingly, science is showing that the evolutionary process has many built in constraints which limit its possibilities and bias its pathways. Take, for example, the ubiquitous phenomenon of convergence - the tendency for highly diverse species to independently evolve similar adaptive (analogous, not homologous) traits. Most of us are familiar with the saber-toothed tiger, the scourge of our hominin ancestors. Less familiar are a group of South American marsupials called the thylacosmilids who independently evolved similar protruding saber-teeth. Convergence can also be seen in a number of specifically human traits. For example, we share a mode of locomotion, bipedalism, with birds, kangaroos, and some dinos. The lateralized and convoluted structure of our brains can also be found in octopi, this despite the fact that vertebrates and cephalopods diverged from one another over 450 million years ago.

In his book "Life's Solution" (2003, Cambridge Press) Cambridge Palaeobiologist Simon Conway Morris documents scores of examples of convergent evolution from insect body designs to the social systems of dolphins and chimpanzees (both fission-fusion). The important lesson is that there are only a limited number of ways that evolution can solve the adaptive problems posed by the earth's ecosystems. Time and again, evolution stumbles upon the same general design features from which to fashion adaptive traits.

Now add to this the Baldwin effect - an idea originally proposed in 1896 wherein organisms are posited to actively shape their own selective forces. For example, suppose some fairly intelligent primates begin fashioning tools, giving them access to new resources and a competitive advantage over non-tool users. Any genetic predisposition facilitating tool use would also be positively selected.

A severe limitation on Baldwin effects has always been the unpredictability of genetic mutation. For any heritable genetic changes to occur (so the thinking has always been) our tool wielding primate would just have to wait around and hope for a lucky "tool use" mutation to pop up. But maybe not. Two recent books, Jablonka and Lamb's "Evolution in Four Dimensions" (2005 MIT press) and Kirschner and Gerhart's "The Plausibility of Life" (2005, Yale University Press) discuss connections between recent work in genetics and Baldwinian processes. What if the primate's tool use actually raised the probability that a tool-relevant genetic change would take place which could then be passed along to offspring?

Recent genetic research (in a field called epigenetics) shows that experiences occurring over one's lifetime can produce heritable genetic changes. For example, mice exposed to two weeks of environmental enrichment (more social interaction, activity, novel objects to explore) show evidence of enhanced memory function (not surprising). More surprising is that their offspring also show evidence of enhanced memory even though they were never exposed to environmental enrichment (Journal of Neuroscience, 29, p. 1496). Thus, the increased environmental stimulation created a genetic change in the parents that was then transmitted to offspring. This change appears to involved altered patterns of gene regulation (how genes are turned on and off during development). Similar effects have been noted in humans (see European Journal of Human Genetics, 14, p. 159).

Convergence, epigenetic inheritance, and Baldwin effects are only a few of the mechanisms serving as directional constraints on evolution's pathways. In his review of the various factors affecting the evolutionary process, anthropologist Melvin Konner concludes:

"There are no intrinsic driving factors in evolution, but there are intrinsic constraints and canalized paths along which either evolution or development may more easily proceed" ("The Evolution of Childhood," Harvard Press, 2010, p. 59, emphasis in original).

Of course, none of these constraining factors guarantee our arrival on the evolutionary stage. They do, however, raise the odds that in time a complex, rational, self-aware creature capable of entertaining both scientific and religious ideas might emerge.

The more we understand evolution, the less it seems like neither the bogeyman that creationists fear nor the universal God-dissolving acid some atheists crave.

Though some may believe that moving the science/faith dialogue forward is best left to scientists, scholars, and theologians, we at BioLogos recognize that our pastors play an invaluable role in the conversation. Across the globe, pastors are helping their congregations work through difficult issues of science and faith with honesty, insight, and a gentle spirit. To this end we present an ongoing series recognizing sermons (and the pastors who give them) that are helping to promote the harmony of science and faith. Today's sermon comes from Rev. John Piper, author and Pastor for Preaching at Bethlehem Baptist Church in Minneapolis, Minnesota. Click above to hear an excerpt. Below, is a brief summary written by BioLogos editorial staff. The full sermon, which we highly recommend can be downloaded here. Finally, if you know a sermon or podcast related to science and faith that has especially spoken to you, please let us know.

Genesis 1:26-28 states that God created human beings and placed his image within them, both male and female. Although these Biblical statements are not exclusive to Christian belief, Dr. John Piper argues that they point to Christianity. In this eloquent sermon, he examines these related, but distinct truths in Scripture (creation, creation-in-the-image-of God, and creation-as-male-and-female) and demonstrates how they obtain completion and significance in the revelation of Jesus Christ.

Piper begins with a discussion about God’s purpose in the creation of humankind. The assertion that God designed people pleads the question: for what purpose or end have all human beings been formed? The Old Testament indicates that humanity was made to steward the things of the earth and to reflect the glory of God in the world. It speaks of being created to show forth the glory of God (Isaiah 43:7). It also speaks of how the earth will be filled with the knowledge of the glory of the Lord. (Habakkuk 2:14). However, the Hebrew Scriptures end with creation utterly unfinished and the hope of glory still to come. Stopping the story there, begs for the rest to be told, and it is, but only in Christ:

For it is the God who said, “Let light shine out of darkness,” who has shone this light in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ. (II Corinthians 4:6 NRSV.)

Then, Piper speaks about how God has created us in his image, and this, he says, must have something to do with why we are here. His purpose in making us must have something wonderful to do with our uniqueness. We, alone out of all his created beings, are made in the image of God. The current state of the world, however, shows what a mess we have made of this dignity. We have marred God’s image “almost beyond recognition.” This causes one to wonder: can a person truly be in the image God when evil abounds? Piper answers this by referring to the words of God to Noah in Genesis 9:6: "Whoever sheds the blood of man, by man shall his blood be shed; for God made man in his own image." This verse fully affirms God’s likeness in humanity. Even in a world where sin abounds, humankind is still created in God’s image—badly distorted, true, but still the image of God. Piper expounds:

Do you feel that you are like God in the way you should be? So here again the belief that we were created in God's image begs for a completion—in this case a redemption, a transformation, a kind of re-creation. And that is exactly what Christianity brings. "By grace are you saved through faith; and this is not your own doing, it is the gift of God—not of works, lest any man should boast. For we are his workmanship, created in Christ Jesus for good works . . . Put on the new nature created after the likeness of God in true righteousness and holiness" (Ephesians 2:8–10; 4:24 RSV).

So knowing that we were created in the image of God, our dilemma begs for an answer. And Jesus, he says, is that answer; he begins the reclamation project called sanctification that will end in the glory that God intended for humankind in the first place.

Next, Piper focuses on how God created us male and female. And this too, given the alienation depicted as the story of Adam and Eve comes to a close, begs for completion and points to Christ. How? It does so in at least two ways. The first comes from the “mystery” of marriage. The other comes from the historical ugliness of male-female relationships when sin abounds.

First is the mystery. While Genesis 2: 24 sets forth the institution of marriage saying, “…a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh,” it does not fully explain the significance of it. For this reason, the Apostle Paul describes marriage in Ephesians 5: 31 as a great mystery. Paul then describes how marriage is symbolic of Jesus Christ’s covenantal relationship to the Church. The story of man and woman in marriage begs for completion, and it is only fulfilled in Christ’s covenant with his people, his commitment to the church. So that’s the mystery, and it is only fully realized with the coming of Jesus.

Second is the ugliness that too often characterizes male/female relationships in sin. Piper goes all the way back to the beginning where in Genesis 2:24 Adam disgustingly blames woman, not himself, for his sin. There, Piper says, is the beginning of all domestic violence—man blames woman for his own failures. One consequence of Adam and Eve’s sin is a curse upon man and woman’s relationship in Genesis 3: 16(NASB): “…In pain you will bring forth children; yet your desire will be for your husband, and he will rule over you.” Piper makes it clear that the model of a domineering man and a devious woman is the result in marriage when sin has its way. However, Jesus came to reverse the curse and heal the twisted relationship between men and women that has created inequality and oppression. In 1 Peter 3:7, Peter describes man and woman as fellow heirs of the grace of life that is found in Jesus. Therefore, it is in Christ that equality, complementarity, harmony, mutual respect, and love exist between man and woman.

So the fact of being created in God’s image in Genesis, cries out for completion as the Old Testament ends.

1. Humankind is created to manifest the glory of God, but the work is clearly unfinished.
2. The image of God has been deeply marred by self-centered rebellion against God (sin). The work of God cries out for completion
3. The male/female relationship is damaged by the desire to dominate, but it points to completion in the mystery of Christ and the bride for which he gave his life—the Church.

In all cases, creation only moves to completion, as we are “utterly and radically and uniquely devoted to the Lord.”

Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual service of worship. And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect. (Romans 12:1, 2, NASB)

Full Sermon

While these are indeed complex questions, some of the problems do stem from misunderstandings about what randomness means in a scientific sense and what role it plays in evolution. To help clarify some of these details, we offer these resources.

The “Randomness” installment of our Distinctions series (first posted earlier this year) looks at some of the basic misconceptions about the role of randomness in evolution. While it is understood by many simply to mean blind, undirected and purposeless, in truth, randomness is far more complex and awe-inspiring than this overly-simplified definition. Whether through genetic mutations or the combinations that occur between sperm and eggs, these processes can be seen as the continual unfolding of something that is decidedly not random--creation itself. Randomness, in essence, generates certainty. This is further illustrated in the second video.

In the clip “Randomness” from the upcoming film A Leap of Truth by Ryan Pettey, Richard Colling, Ard Louis, and John Polkinghorne offer several examples of random processes leading to order rather than disorder. As Dr. Louis points out, the scientific definition of “randomness” is quite different from our everyday understanding of the word. In fact, random generation is the most efficient way to generate complexity. Polkinghorne further notes that we live in a world where the balance of random mutations is almost perfectly tuned for fruitful life on Earth. This, we learn, is God's process: Randomness given time, can lead to that which is nearly certain.

This is beautifully illustrated in the following re-post from last year. Here, in a blog called "That's Random," Kathryn Applegate offers two examples of random motion leading to certainty in the process of assembling a virus. Because random processes can lead to that which is almost certain, it is not at all surprising that this has frequently been used by God over billions of years to create order out of chaos--God's creation, by God's way, in God's time.

That's Random

You hear it all the time: “That’s so random!” When used by people of my generation, the word “random” can simply mean “cool” or “surprising.” Or it can mean something like “disconnected,” as in the phrase, “I had a random thought” (which returns 189,000 hits on Google, by the way—random!).

Despite this usage, most of us know that randomness has something to do with probability, and that it often implies a lack of conscious intentionality. But what do mathematicians and scientists mean when they say something is random? Can a random process lead to an ordered, even predictable outcome? Is there evidence that God makes use of random processes to fulfill his creative purposes?

These are big questions, and we won’t address them all today. But I think randomness is an important topic to cover for two reasons: 1) it is integral to many processes in biology (and math, physics, chemistry, etc.), and 2) it is commonly misunderstood to be incompatible with Christianity.

As I said above, most of us know that randomness has something to do with probability. If you pick a card “at random” from a shuffled deck, you have a small probability of drawing an ace (4 out of 52, or a 7.7% chance). If you flip a coin, you have an equal probability of getting heads or tails.

Randomness also seems to imply a lack of intentionality or purposefulness. After all, you might hope for an ace when you draw a card, but you can’t choose one on purpose. You might call heads when you flip a coin, but you can’t know beforehand what the outcome will be. Thus the outcome is indeterminate, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.

It should be noted that indeterminacy does not imply that God does not have foreknowledge of future events. Christians ought not to be uncomfortable with the idea of God interacting with his creation through chance. We often describe a seemingly-random (i.e. unplanned by us) sequence of events as being “providential,” or planned by God. A good introduction to the way divine action could drive physical processes can be found in this Question.

In biology, it is very hard or impossible to calculate precise probabilities for most processes, so when we say a process is random, we typically mean it is extremely unpredictable. Eventually we will discuss randomness within biological evolution, but first we must consider some simpler processes, like the self-assembly of a virus.

Viruses are remarkably efficient entities. Coiled tightly within a protein-based shell is a small amount of DNA needed for self-replication. The shell, called a capsid, is made of many repeating protein subunits and is therefore highly symmetrical (see figure). Important biomedical insights have certainly been gleaned from structural studies of viruses, but viruses also teach us about the emergence of order from non-order.

The virus life cycle has four main steps: 1) enter a host cell, 2) hijack the cell’s replication and translation machinery to make many copies of itself, 3) assemble into many virus particles, and 4) exit the cell to invade another host.

When I first learned about this process, I found it very hard to believe it just “happens.” The idea that a bunch of molecules bumping into each other inside a crowded cell could spontaneously assembly into a fully-functional virus seemed a bit far-fetched. Many viral capsids have over 100 protein subunits that must interact with each other in just the right way, or it won’t work. Surely there must be something driving this process, right?

There is! Random motion. I had to see it to believe it. I distinctly remember sitting in class during my first year of graduate school when the professor demonstrated self-assembly of a virus using a 3D model as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.

As the narrator explains, sub-assemblies form and break apart en route to the most stable structure, the full capsid. As the sub-assemblies begin to form, further associations with free subunits become more favorable and as a result occur rapidly, while the final steps may take considerably longer. While the subunits in the model are rigid, in reality the proteins take on multiple conformations, allowing the capsid to “breathe.”

Amazing as it is, the system we just considered—one virus capsid in a jar—is pretty simple. One wonders how self-assembly can happen in a crowded cell, where there are countless other molecules diffusing around, potentially getting in the way. We can’t directly see how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.

Consider two viruses, where each protein subunit in one virus is the mirror image of the corresponding subunit in the other. Putting the two viruses together by hand would be pretty tricky, because the constituent parts look so similar. But random motion can do the job in short order:

From this model, we can see clearly, in real-time, how distinct complex structures can arise from their parts randomly interacting with one another. Many large viruses also use special scaffolding proteins to assist in the assembly process, and some even use their own genomes as a scaffold. In addition, two closely-related viruses that happen to infect the same cell can exchange parts to create a new virus. This is one way viruses can evolve quickly to evade the host’s immune system.

Here we have seen how viruses demonstrate a principle inherent in God’s world—that order can emerge out of chaos from random processes.
