"Anyone approaching the Resurrection accounts in the belief that he knows what rising from the dead means will inevitably misunderstand those accounts and will then dismiss them as meaningless" (p. 243).

In fact, if Jesus' Resurrection were "merely" coming back to life in any way that we might comprehend, then it would be of little significance.

"Now it must be acknowledged that if in Jesus' Resurrection we were dealing simply with the miracle of a resuscitated corpse, it would ultimately be of no concern to us" (p. 243).

So what then does Resurrection mean? For Benedict it represents a new dimension of reality breaking through into human experience. It is not a violation of the old; it is the manifestation of something new.

"Jesus had not returned to a normal human life in this world like Lazarus and the others whom Jesus raised from the dead. He has entered upon a different life, a new life -- he has entered the vast breadth of God himself..." (p. 244).

Because it is something entirely new, it cannot represent a violation of natural law as understood by science.

"Naturally there can be no contradiction of clear scientific data. The Resurrection accounts certainly speak of something outside our world of experience. They speak of something new, something unprecedented -- a new dimension of reality that is revealed. What already exists is not called into question. Rather we are told that there is a further dimension, beyond what was previously known. Does that contradict science? Can there really only ever be what there has always been? Can there not be something unexpected, something unimaginable, something new? If there really is a God, is he not able to create a new dimension of human existence, a new dimension of reality altogether?" (p. 246-7)

Thus, in this view, Resurrection (as with all true miracles) is not contrary to science, but an indicator that science does not (yet?) describe the full expanse of reality. Indeed, some may argue that science itself contains similar "indicators." The 11 (or so) dimensional universe required by some versions of string theory, the multiverse theory of the universe where ours is but one of an infinite array of universes with variable physical laws, quantum entanglements, "spooky" action at a distance, the mysterious emergence of consciousness from inorganic matter -- all push the limits of human reason and imagination, suggesting to some that reality may be far more complex than the human mind can grasp.

For a moment, let us entertain the possibility that Resurrection is as Benedict interprets it: not a violation of natural law but an indicator of something beyond our scientific understanding of the universe. This has interesting implications for understanding how believers and skeptics approach the issue. If Resurrection does not violate science, then science does not necessarily constitute an impediment to accepting the reality of Resurrection. If the difference between the skeptic and believer is not science, then is it just a matter of imagination? The believer imagines greater possibilities for the universe than the non-believer. While this is possible, it seems questionable. To my knowledge, no research has found differences in imaginative abilities between religious and non-religious people. Moreover, contrarian examples easily come to mind: Isaac Asimov was an atheist but hardly lacking in imagination when it came to science fiction. I tend to think that both believers and non-believers can imagine (with varying degrees of effort, I'm sure) the new possibilities implied by Resurrection.

Thus, if it is neither imagination nor science that prompts skepticism about Resurrection, then what is left? I suggest that it comes down to a question of authority: At what point does one allow imaginative possibilities to have authority over how one lives? To the believer, Resurrection has an authority that science fiction does not. Resurrection is not thought-provoking entertainment. It requires far more than just imagining greater possibilities for the universe. It requires a change of life, here and now. Unlike the microscopic hidden dimensions of string theory, the new dimension implied by Resurrection has "broken though" into everyday reality and demands a response -- even if that response is to actively ignore it.

Now, what convinces the believer that Resurrection merits such authority when other imaginative possibilities such as extraterrestrial life or time-travel do not? The answer here appears to be historical commitment. There's no record of people committing themselves to the point of martyrdom to other imaginative possibilities as they have to Resurrection. The earliest example of such commitment being found, of course, in the dramatic post-crucifixion turn-around of the Apostles. Such an astounding change of heart, followed by an unwavering commitment capable of altering human history demands a categorically unique explanation: Resurrection.

The believer's argument, however, remains unconvincing to the skeptic. However impressive they might be, a change of heart and steadfast commitment do not necessarily add up to a new dimension of reality. Extraordinary claims require extraordinary evidence. Fair enough. So a key question regarding the interpretation of Resurrection is this: Is the post-crucifixion history of Christianity extraordinary? Does it compel the dispassionate observer to concede that a categorically unique event could plausibly be its best explanation?

It ought to be upon questions such as those above that skeptics and believers respectfully engage one another, rather than the simplistic and often acrimonious sloganeering that has increasingly become the norm.

What does it mean for humanity to be created “from the dust of the ground?”

In many ancient Mesopotamian creation stories, human beings were depicted as deriving from some physical part of the gods. Often this was the result of conflict: humans arose from the blood, flesh or tears of gods slain by other gods. Humans created in this fashion were supposed to serve the gods by performing menial work that the gods had tired of doing themselves. The lot of humanity, then, was one of violence and servitude.

In the Israelite creation stories reflected in Genesis 1 and 2, however, humans are made from the ordinary material of creation: “dust.” Humans are made of earth-stuff, not god-stuff.

At first glance, it may seem that this lowers the status of the human creature. We might ask the question raised by Eliphaz in the book of Job:

Can a mortal be more righteous than God?
Can even a strong man be more pure than his Maker?
If God places no trust in his servants,
if he charges his angels with error,
how much more those who live in houses of clay,
whose foundations are in the dust, who are crushed more readily than a moth! (Job 4:17-19)

Indeed, our humble origins ought to remind us of the fragility of our lives. As the Psalmist says,

You turn people back to dust, saying, “Return to dust, you mortals.”
A thousand years in your sight
are like a day that has just gone by,
or like a watch in the night.
Yet you sweep people away in the sleep of death—
they are like the new grass of the morning:
In the morning it springs up new,
but by evening it is dry and withered.

The elements of which our bodies are made are ordinary and abundant. Science tells us that approximately ninety-three per cent of the mass in a living human body is comprised of elements first formed through nuclear fusion in the hearts of stars. Through almost unimaginably vast and ancient cycles of stellar formation and supernova explosions, this “stardust” of elements has been spread throughout the universe. It is as though God scattered the stars across space and time to seed the universe for life, including your life and mine. And we are thereby inseparably connected to each other, to the air we breathe, to the ground we tread, to all the creatures that fill the skies and crawl upon the earth and teem in the seas, to the depths of all the heavens. We are not transcendent of creation. We are creatures.

Yet we are creatures into which God breathed the “breath of life.” We are stardust and more than stardust. We are not reducible to our constituent chemicals. A “man” or a “woman” is not just a gooey sack of water, carbon and trace elements. Hydrogen, oxygen and carbon are not aware of their own existence. These elements cannot reason or pray or love or write poems. Conjunctions of these elements cannot carry any persistent identity across time. They do not exercise will or intentionality or agency. They are not “selves.”

Most of the cells in a human body are in constant flux: aging, dividing, dying, being replaced. The surface layer of human skin is renewed completely about every two weeks. An adult’s skeleton is entirely remade over approximately ten year periods. It may be that only the neurons of the cerebral cortex and a few other types of cells persist throughout the lifetime of a human body. And eventually, it all does return to “dust.”

Yet we think of ourselves as persisting over time, as comprising an “identity,” a “self.” Perhaps the cerebral cortex provides the stable biological platform for identity and selfhood, but something new emerges from the chemical-electrical soup, new patterns of organization, a different level of causation. We can even make choices that reshape ourselves, both physically and psychologically. The very wiring of our brains changes when we make conscious choices. Mind is both shaped by matter and supervenes on matter.

Materialists who wish to collapse all of human identity into brain chemistry overstep the bounds of “science.” A fundamental principle of scientific practice is testability: is it possible to demonstrate empirically whether a proposition is false ? As Saint Augustine observed many centuries ago, the fact that I acknowledge I could be “wrong” about something means that I am a “self” who is capable of making real choices about things that are in fact true or false. “Si fallor, sum” Augustine said – if I can doubt, if I can be wrong, then I must exist. One who is a true materialist “all the way down” cannot test his or her materialism. There is no possibility of “being” right or wrong, indeed no possibility of “being” – there is nothing but chemistry.

Spiritualists who wish to degrade matter in favor of the soul or spirit likewise are not expressing a Christian anthropology. Indeed, one of the first heresies that encountered the early Christian church was Gnosticism. A core belief of Gnosticism was that matter, including the human body, was essentially evil. Salvation for the Gnostics involved the soul’s escape from the prison of embodiment and materiality. The Gnostics treated the body either with disdain – engaging in extreme ascetic practices – or with antinomian abandon – engaging in extreme sexual license. Either way, their practices were rooted in the belief that matter and the body were unimportant. It’s easy to see how this view continually creeps into both our popular culture and our Church cultures.

Christian theology asserts that humans are spiritual creatures, a unity of body and spirit or “soul,” integrated, not reducible downwards to mere matter or upwards to mere spirit. Perhaps there is no better way to bring these themes together than with a Psalm — here is Eugene Peterson’s paraphrase of Psalm 139 in The Message:

God, investigate my life; get all the facts firsthand.
I’m an open book to you;
even from a distance, you know what I’m thinking.
You know when I leave and when I get back;
I’m never out of your sight.
You know everything I’m going to say
before I start the first sentence.
I look behind me and you’re there,
then up ahead and you’re there, too—
your reassuring presence, coming and going.
This is too much, too wonderful—
I can’t take it all in!

Is there any place I can go to avoid your Spirit?
to be out of your sight?
If I climb to the sky, you’re there!
If I go underground, you’re there!
If I flew on morning’s wings
to the far western horizon,
You’d find me in a minute—
you’re already there waiting!
Then I said to myself, “Oh, he even sees me in the dark!
At night I’m immersed in the light!”
It’s a fact: darkness isn’t dark to you;
night and day, darkness and light, they’re all the same to you.

Oh yes, you shaped me first inside, then out;
you formed me in my mother’s womb.
I thank you, High God—you’re breathtaking!
Body and soul, I am marvelously made!
I worship in adoration—what a creation!
You know me inside and out,
you know every bone in my body;
You know exactly how I was made, bit by bit,
how I was sculpted from nothing into something.
Like an open book, you watched me grow from conception to birth;
all the stages of my life were spread out before you,
The days of my life all prepared
before I’d even lived one day.

Transitional Fossils

Some time ago, the Discovery Institute’s Casey Luskin commented on the human origins exhibit at the Smithsonian Institution, suggesting that palaeoanthropologists use evolutionary theory to describe the progression of the human lineage even when they don’t have transitional fossils with which to work. He writes:

What's ironic, however, is that if you ask the question How Do We Know Humans Evolved? the answer you’re given is, “Fossils like the ones shown in our Human Fossils Gallery provide evidence that modern humans evolved from earlier humans.” So whether you find fossils or you don’t, that’s evidence for evolution.

Indeed, it has become an article of faith for those espousing both the young earth creation (hereafter YEC) model and many who hold to the intelligent design model that transitional fossils do not exist and therefore evolution has not taken place. Support for this position usually entails attacking the weak areas of the fossil record, where burial processes have left us little with which to work, or the creation of straw men arguments in which transitional fossils are defined in such a way that none could ever be found. Often this centers on the concept of “missing link,” a term that is habitually used in the popular press and young earth creation and intelligent design literature when referring to fossil remains but which has little to no meaning for biologists or palaeontologists. As Ahlberg and Clack (Ahlberg and Clack 2006) write:

But the concept has become freighted with unfounded notions of evolutionary ‘progress’ and with a mistaken emphasis on the single intermediate fossil as the key to understanding evolutionary transitions. Much of the importance of transitional fossils actually lies in how they resemble and differ from their nearest neighbours in the phylogenetic tree, and in the picture of change that emerges from this pattern.

Contrary to common misconceptions, the fossil record does not record one single lineage for any family of organisms but rather a series of branches, with many related species coexisting synchronously. Darwin hypothesized that the evolutionary record reflected this bushiness and drew such a diagram in his journal. At the time, though, he had little in the way of fossil evidence to back up this position. Much has changed since his day.

An analogy for understanding this “bushiness” was best described by Prothero and Buell (Prothero and Buell 2007). They suggest that the reader consider his or her own genealogy. You and your siblings are the direct descendents of your parents and, while you are similar to them, each of you has different characteristics not shared with them as well as characteristics that you do share. Your parents have siblings as well (your aunts and uncles), and your grandparents are their last common ancestors. These siblings have their own children (your cousins), who have different and similar traits relative to their parents. They are broadly recognizable as being related to you (“oh, I see you have Aunt Edna’s nose”) but three or four generations out, they will become less and less so. These are the “nearest neighbours” that Ahlberg and Clack describe. In this analogy, each of these cousins represents a transitional form from what was (your grandparents) to what will be down the road.

For example, no one would confuse a frog with a salamander but if you trace the fossil record of each back in time, eventually you encounter a fossil, Gerobatrachus hottoni which was recently discovered (Anderson et al. 2008) that is best described as a “frogamander,” having the basal characteristics of both frogs and salamanders. Had we seen such an animal at the time, it is likely we would not have found it remarkable because it would have resembled the species around it. One lineage eventually diverged into frogs, salamanders and other amphibians. Most (just like Darwin proposed in his tree diagram with the little hatch marks at the tip of many branches) went extinct.

Taxonomy and the Beginnings of Human Origins

All life is classified based on a system devised by Carolus Linneaus in 1735 in his remarkable work Systema Naturae. This system gives all recognized species an individual place based on a system of hierarchy. The study of classification is known as taxonomy. A taxonomic ranking for humans would be this:

When a fossil is excavated, the first thing that the palaeontologist does is make a taxonomic assessment of where it fits in a sequence of known fossils. Traits that are shared with other like species or genera are referred to as primitive traits. Examples of this in humans are five fingers and the presence of three arm bones. We share this with all mammals. Traits that are new or are not shared with other like species are referred to as derived traits. Examples of this in humans are the skeletal changes in the pelvis and the foot to allow for walking upright. We do not share these with any other primates.

Transitional fossils in the human fossil record are distinguished at both the genus and species level. This group includes the extinct genera Ardipithecus and Australopithecus and the current genus Homo. All species except Homo sapiens are extinct. Much of the recent study of early humans focuses on the transition from Ardipithecus (‘Ardi’) to Australopithecus (‘Lucy’ and similar fossils) and from Australopithecus to Homo, the genus that led eventually to us. While each of the australopithecine species identified in the fossil record has derived characteristics that separate them from their ancestors and from each other, only one led to the genus Homo.

In future posts, I will describe the evidence for human evolution and why this evidence is compelling. It suggests that we have had a long, varied history filled with great leaps of change, crushing defeat, and eventual expansion into all areas of the globe.

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.

Today, as I write, I am no longer in the desert of southern California, nor in the beech-maple forest of New Hampshire, but on a glacial drumlin in Waubesa Wetlands—a large marsh four miles south of Madison, Wisconsin. Here Ruth and I have our home, and here I study creatures whose watery habitats my neighbors and I have worked to save from eventual destruction. While my desert study site now is covered by a city where people live alone in the land—absent the desert creatures—my wetland study site remains occupied by all kinds of native plants and animals. Embracing it is the Town of Dunn, whose land stewardship plan helps people understand, serve, and maintain this and the other ecosystems. Our town stewardship plan encourages restoration of the landscape, protects agricultural lands, and strives to transmit an intergenerational heritage of secure and wholesome homes, livelihoods, and habitats for the animals, plants, and people that live here. We live largely in harmony and accord.

House-building on slabs poured onto desert sands first alerted me to the question of praxis, the third point on the napkin. But it was later, in my work as organizer of the Waubesa Wetlands Scientific and Agricultural Preserve, and as supervisor and later as chair of the Town of Dunn, that I came to realize that science and ethics do no earthly good unless put into practice. In serving my town, I came to apply what I had learned in the desert: praxis uninformed by science and ethics usually creates more problems than are solved.

“How do you put it all together?” those students in New Hampshire wanted to know. For me, it was building a framework for stewardship that simultaneously considered the questions “How does the world work?” “What is right?” and “What then must we do?” This science-ethics-praxis triad is a framework for living, for learning, for teaching, and most importantly for acting. It is a framework for stewardship.

In order to live and act rightly in the world, we need to know how the world works. We need to know how the systems that sustain us work, and how we interact with them. Without such knowledge we could drown in a flash flood, have our homes undercut by desert winds, cross the street in the path of an oncoming car, or get sick from consuming foods with toxic ingredients. As human beings develop more and more of the world, and as the reach of human actions extends regionally and globally, our knowledge must increase accordingly. This knowledge is not limited to what we acquire from a formal education; it also includes the knowledge we gain from family and friends, and from experience and experiment. In order to live and act rightly in the world, we need to know how the world works.

In order to live and act rightly in the world, we need to know what we ought to do. A century ago, this question was addressed in many colleges across America in a course for graduating seniors on moral philosophy. The purpose of this course was to convict students that they should apply their knowledge for the pursuit of good instead of pursuing self at others’ expense. At my university, this aspect of college education is expressed in a quotation from Abraham Lincoln carved in stone on a bench behind Lincoln’s statue at the top of Bascom Hill: “Let us have faith that right makes might, and in that faith, dare to do our duty.” The question “What is right?” is represented by the ethics corner of our triad. Moving directly from the Science corner to the praxis corner, or from the ethics corner to the praxis corner, proves problematic, even disastrous. Consider the result of going from knowledge of nuclear fission (science) directly to producing and dropping an atomic bomb (praxis), or moving from the belief that death is bad (ethics) to removing dead wood from forests (praxis); both are examples of these disastrous shortcuts.

But knowing the science and observing the ethics of this stewardship framework does absolutely no good if it is not put into practice—placed into service. By themselves, the very best science and the most substantial ethics are no substitutes for action. We need to act appropriately and deliberately in the light of scientific and ethical knowledge. Praxis by itself, without being grounded in science and ethics, results in mere activism—activism that is unlikely to do good and that may produce harm. All three corners of the triad are essential—but not by themselves. Taken together and working interactively, they provide a framework for stewardship.

But will these three operate in dynamic interaction? Will they interact in ways that preserve and achieve the integrity of human life and the environment? The answer depends on what we know and understand about ourselves and the world (science), what we believe we should do (ethics), and what we in fact do, and how we respond to our successes and failures (praxis). It depends on our will, our motivation, our determination, and our dedication to strive for a harmonious world of creatures before their Creator. What might make us strive for such a world?

Part 3 explores the challenge of translating ideals into concrete actions.

Part of the BioLogos mission, then, is to show how all things hold together in Christ—to show how a Christian worldview integrates the knowledge we have of God through the Scriptures with the knowledge we have of God through the other areas in which he reveals himself as Creator and Redeemer. Our website contains a wealth of Christian scholarship in a wide range of fields—from biology, to cosmology, to mathematics, to Biblical studies, to history, to theology—all demonstrating that the best contemporary science is compatible with Biblical Christian faith. But today we introduce a new tool—the BioLogos Navigator—to make these posts more accessible, and to show how they inter-relate (see sidebar on the right).

Modeled on the astrolabes that early astronomers and sailors used to orient themselves under the heavens, our Navigator makes the cross of Christ the starting point by which we understand the cosmos. Each of the four arms of the cross represents one of the domains of knowledge and experience through which God reveals himself to the world: Scripture, the Church, Nature and Culture. These domains are not in opposition to each other, but are complementary and inter-related areas through which we can recognize God at work in the world. Linking these four domains is a network of specific topics relevant to the science and faith conversation. Their arrangement suggests how each relates to the four domains but also to teach other. Clicking on an individual topic tag highlights not only that topic, but other topics that are linked to it—sometimes in unexpected ways.

Clicking a topic tag a second time takes you to the Topic Landing page: a curated selection of the best resources on that subject from the BioLogos archives. (The image above shows the Christianity & Science—Then and Now Landing page, complete with Navigator and highlighted tags.) At the bottom of each page is a link to our Resource Finder, where you can investigate additional materials on that topic, as well. By exploring the relationships between the topics on the Navigator itself, and by delving deep into each topic via the resources presented on the landing pages, readers can focus on specific aspects of the harmony between science and Christian faith while also getting the wide view of God’s providential work in all things in the heavens and on the earth.

In the coming days and weeks, the BioLogos Navigator will be more fully integrated into the rest of the site, accessible directly from the Forum homepage and from the Resources dropdown list at the top of every page. We’ll also be including features that help place each blog post on the “knowledge map” defined by the domains and topic tags. Finally, the Topic Pages will also be periodically updated with the latest and best new materials in each topic. In the meantime, you can access the Navigator by clicking anywhere on the small image in the sidebar, above, and find a link to this post at the upper right corner of our homepage. So take some time to explore our site with this new tool, which we think will to help orient our readers in the science and faith conversation, while always pointing to Jesus, the Christ, through whom all things were made.

The first video, “10 Questions with Katherine Hayhoe”, introduces the scientist in a brief and lighthearted interview. Hayhoe is presented with 10 questions concerning her personal life and beliefs. When asked, she explains that one thing people should know about Christianity is that having a relationship with the God of the universe is one of the most incredible experiences that a person can have. As the video unfolds, the viewer quickly begins to realize that, despite her unique profession of two seemingly incompatible beliefs, Hayhoe is a remarkably sane and “normal” individual. Her role model, she explains, is her father-- the person who first introduced her to science and showed her that it could be “really cool”. On a more serious note, the scientist admits that being both a scientist and a Christian can be difficult. The most frustrating thing about her position, she says, is the amount of disinformation which is targeted at her very own Christian community.

In the second video, “Climate Change Evangelist”, Katharine Hayhoe delves into deeper discussion of the perceived conflict between climate change and Christian faith. She explains that admitting her identity as a Christian scientist can be uncomfortable. Since evangelicals are the targets of much disinformation concerning science in general -- and specifically the science surrounding climate change -- many people in the church have a misguided view of the subject and do not look kindly at her career choice. One woman encountered by Hayhoe at a church in Texas, for example, believed that global warming was a lie taught in schools to mislead her children. In an effort to realign misguided views like these, Katharine Hayhoe and her husband wrote a book addressing the deep-rooted emotions often associated with climate change. People fear that addressing the climate issue will bring forth changes in the economy and uproot their way of life. However, Hayhoe encourages her viewers to act out of love, as the Bible calls us to do, rather than out of fear. Acting out of love inspires us to consider the poor and disadvantaged people around the globe when we respond to the reality of a changing climate.

In the final segment of this three part video montage, Hayhoe addresses the question of what climate change means. Specifically, she is concerned about how global warming affects people on a personal level. While global warming generally brings to mind melting ice caps and polar bears, its implications are far more widespread, affecting the lives of everyone around the world- from cotton farmers in Texas to public health workers in Chicago. If nothing is done to change current emission levels, the number of days per year which exceed 100 degrees Fahrenheit, for example, will begin to increase dramatically, and if emissions are increased, many areas will even develop extreme conditions like those seen currently in Death Valley. Hayhoe’s goal is to demonstrate clearly that the only way to preserve the world for future generations is to significantly reduce dependence on inefficient means of getting energy and instead transition to cleaner renewable energy sources.

Editor's Note: These videos first appeared on the Nova program "The Secret Life of Scientists & Engineers".

The Denisovans, an extinct hominid group that interbred with modern humans, made the news again lately with the publication of a more detailed study of their genome. One of the many interesting findings was that the Denisovans share the same chromosome 2 fusion that modern humans have. In this post, I review what we know about the origins of human chromosome 2, and then discuss the new Denisovan findings and their implications.

The origins of human chromosome 2: a brief review

Though I have discussed the evidence for a fusion event leading to human chromosome 2 before, perhaps a brief review of the evidence is in order. The human genome is made up of 23 pairs of chromosomes (for a total of 46 chromosomes). This makes us something of an oddity among living great apes, all the rest of whom have 24 pairs of chromosomes (for a total of 48). Given that there are many independent lines of evidence that support the conclusion that we share a common ancestor with other great apes, this poses something of a conundrum: how is it that our species arrived at this specific chromosome number? If we were to represent this “problem” on a phylogeny, or tree of relatedness, it would look something like this (not to scale):

Our closest living relatives, chimpanzees and bonobos, both have 48 chromosomes, as do all other great apes such as gorillas and orangutans. This pattern has one of two explanations, one of which is much more likely than the other. Either the common ancestor to these species had 48 chromosomes, and there was an event that reduced that number to 46 specifically on the lineage leading to humans (option A), or the common ancestor species had 46 chromosomes, and there were independent, repeated events that increased chromosome number in all other great ape species (option B). We can compare these options by placing the required event(s) on the phylogeny (again, not to scale):

It should be obvious that the option that requires the fewest events is the more likely one – in this case option A with an event that reduces chromosome number in the lineage leading to humans. The other option, that of repeated, independent events to increase chromosome number, remains a formal, but unlikely, possibility. Events that reduce chromosome number are not frequent occurrences, so Option A is more likely than Option B.

We can also find further support for Option A, because it predicts a specific type of event, namely one that reduces chromosome number. Since loss of a large amount of chromosomal material is almost always detrimental, we need an event that reduces chromosome number without losing information. One way for this to happen is for two chromosomes to fuse together and become one. Initially, this event would produce an individual with 47 chromosomes, where two different chromosomes get stuck together. Contrary to what is often assumed, this individual would be fertile and able to interbreed with the others in his or her population (who continue to have 48 chromosomes). In a small population, over time, two relatives who both have one copy of the fusion chromosome may mate and produce some progeny with two copies of the fused chromosome, or the first individuals with 46 chromosomes. Since either a 48-pair set or a 46-pair set is preferable for ease of cell division, this population will either eventually get rid of the fusion variant (the most likely outcome), or by chance will switch over completely to the “new” form, with everyone bearing 46 chromosome pairs. While not overly likely, this type of event is not especially rare in mammals, and we have observed this sort of thing happening within recorded human history in other species. Some mammalian species even maintain distinct populations in the wild with differing chromosome numbers due to fusions, and these populations retain the ability to interbreed.

Further evidence for a fusion event in the lineage leading to modern humans comes from comparing synteny, or gene locations and orders on chromosomes within modern great apes – an issue we have discussed here before. In brief, what we see in human chromosome 2 is exactly what we would predict for a fusion event. When compared to other great apes, we see the genes on human chromosome 2 match up, in order, with two smaller ape chromosomes. We also see that sequences used at the tips of chromosomes are present at the proposed fusion site, and that human chromosome 2 has not one but two sites for the cell cytoskeleton to attach to for cell division – but that one of the sites is mutated and not functional, though it lines up precisely with the location of this site on the appropriate ape chromosome. Together, this evidence consistently supports both common ancestry for humans and great apes, and specifically that the difference we see in our chromosome numbers arose due to a single fusion event. I briefly discussed this evidence in my last post where I describe how I teach some of this material and the compelling impact it has on students exploring the evolution question for the first time.

Enter the Denisovans

With that as background, we are now prepared to appreciate a new finding that comes from genomics work done on the Denisovan hominids, an archaic species that is more closely related to Neanderthals than to us, but that nonetheless interbred with some anatomically modern humans as they migrated out of Africa and populated the globe. (For those not familiar with the Denisovans, or the evidence for our interbreeding with them, both Darrel Falk and I have written on this previously, here and here). Recently, a more detailed understanding of the Denisovan genome was published, and nested in the new information is the discovery that the Denisovans share the 46 chromosome set with the same fusion that we have. This strongly supports the hypothesis that the fusion event predates the separation of our species. If we were to represent this on a phylogeny, we can now place this event with more accuracy than before (as before, the phylogeny is not to scale):

Despite this new information, one obvious question remains. Did the Neanderthals also have the 46-pair set? From looking at the phylogeny above, we can see that the most likely answer is that they did, since the fact that the Denisovans had it strongly implies that the last common ancestor of humans and Neanderthals / Denisovans had it as well, and the Neanderthal-Denisovan split comes later. While the Denisovan DNA samples are of high enough quality to make this assessment, we do not yet have Neanderthal DNA of high enough quality to do the same analysis with current methods (though one additional feature of the new work on the Denisovan genome is developing more sensitive DNA sequencing techniques that may resolve this question in the future).

In other words, this fusion seems to be an ancient one, predating our species by several hundred thousand years. Present estimates of the last common ancestor between humans and Neanderthals / Denisovans range at about 800,000 years ago.

Implications for understanding our “becoming human”

The main implication from this work is that it places the fusion event well before the advent of our species. I’ve often chatted informally with Christians about evolution, and at times some have thought that this fusion event was what “started” our species, or made our species unable to interbreed with other groups. Some have even suggested that perhaps the fusion event was what produced the first human (i.e. Adam).

Note that thinking this way suggests a misunderstanding of how chromosome fusions occur and what effect they have on their hosts. A fusion does not precipitate a speciation event, but rather the individual with the fusion remains a part of his or her population, and able to interbreed, even if with reduced fertility. Also, there is no necessary biological effect or change that the fusion produces on the appearance of the organism. These misunderstandings aside, however,what this new evidence shows is that this fusion event took place long before modern humans arose at around 200,000 years ago. Indeed, the 800,000 years ago date for the last human - Denisovan common ancestor means that this is the most recent date possible for the fusion. While it is an interesting piece of our evolutionary history, it doesn’t seem to have much to do with how we came to acquire the traits that set us apart from, and ultimately outcompete, other similar species.

Asa Gray

If Thomas Huxley earned the title of "Darwin's bulldog," then Asa Gray should be remembered as "Darwin's dove." Whereas Huxley enjoyed a good fight in his defense of Darwin's theory, Gray sought to mediate and bring sides together around a common understanding of "good science." As Darwin's strongest and most vocal scientific ally in the United States, Gray recognized the scientific importance of Darwin's efforts for the growing professionalism of biological researchers.

But as an orthodox Christian, a Presbyterian firmly devoted to the faith expressed in the Nicene Creed, Gray saw in Darwin's theory both evidence for his philosophical commitment to natural theology and support for his opposition to the idealism advocated by Louis Agassiz and the Naturphilosophen in both Europe and America. Indeed, Agassiz's advocacy of Platonic forms as a basis of biological understanding (e.g., "A species is a thought of the creator")¹ would be a major source of American opposition to Darwin's theory.

Professor of botany at Harvard during most of the middle half of the nineteenth century, Gray was one of the few members of the scientific community to whom Darwin revealed his theory before the publication of On the Origin of Species, and, from what I can tell, the only American. Gray and Darwin met briefly in January 1839 during one of Gray's visits to England. Later, during the 1850s, Darwin wrote Gray on several occasions requesting information--a practice that Darwin frequently employed. In 1854, Darwin's friend and confidant, Joseph Hooker, showed Darwin Gray's review of Hooker's Flora of New Zealand, in which Gray had argued strongly against Louis Agassiz's idealism and had raised questions from his own work on the stability of species. Gray was not yet ready to deny their permanence, but hybrids and other observations were beginning to trouble him.

The next year Gray wrote a lucid and penetrating positive evaluation of Alphonse De Candolle's two-volume Géographie botanique raisonnée, a pioneering work dealing with plant geography and distribution from a statistical perspective. Hooker had sneeringly dismissed the work. In A. Hunter Dupree's authoritative biography of Gray, he describes Gray's puzzlement at Hooker's response in these terms:

Although in the long view Gray's evaluation of the epoch-making nature of De Candolle's book was more justified than Hooker's sneers, [Gray was confused by his response, for] Hooker seemed to be talking with a more comprehensive theory definitely in mind, some reason for taking his position, which he did not divulge and which his friend [Gray] did not possess.²

Darwin, however, saw in both Gray's review of Hooker's book and in his comments on De Candolle's tome that Gray was troubled by some of the same empirical data that had been bothering him. In April 1855, Darwin wrote Gray to urge that Gray update his Manual of the Botany of the Northern United States first published in 1848, and especially to address the issue of the range of Alpine plants in the United States. Specifically, he said: "Now I would say it is your duty to generalise as far as you safely can from your as yet completed work."³

Behind this request was Darwin's desire to test his impression that Gray could make a good ally. Gray passed the test, and finally, in July 1857, Darwin let Gray in on his theory of the transmutation of species. Gray was never an uncritical supporter, and there are many evidences in the correspondence between these two scientists that Gray was willing to challenge Darwin and disagree with some of his conclusions. Nevertheless, Gray saw the importance of Darwin's work and the ways in which it provided answers to the troublesome issues that he had confronted in his own botanical efforts.

Gray responds to Darwin's theory

After considerable interchange--one might even say debate--among Gray, Darwin, and Hooker, Gray wrote to Hooker in October 1859 (one month before the publication of On the Origin of Species) saying that he had absolutely no problem with cognate species arising by variation. He did, however, raise a concern that would be the source of much future discussion. He wondered about Darwin's "carry[ing] out this view to its ultimate and legitimate results,--how [do] you connect the philosophy of religion with the philosophy of your science." He added: "I should feel uneasy if I could not connect them into a consistent whole--i.e., fundamental principles of science should not be in conflict."⁴

When Origins was published, Gray wrote a clear, positive, yet critical review in The American Journal of Science. Aware of mounting religious opposition, he ended his review by arguing that whereas one could use Darwin's theory in support of an atheistic view of Nature, one could use any scientific theory in that way. He wrote: "The theory of gravitation and ... the nebular hypothesis assume a universal and ultimate physical cause, from which the effects in nature must necessarily have resulted."⁵ He did not see the physicists and astronomers who adopted Newton's theories as atheists or pantheists, though Leibniz earlier had raised such reservations. And a similar situation existed with the origin of species by natural selection. Darwin, Gray continued: "merely takes up a particular, proximate cause, or set of such causes, from which, it is argued, the present diversity of species has or may have contingently resulted. The author does not say necessarily resulted."⁶

This far Gray could go with Darwin. But there was a point at which he parted company, and that was the fortuitous randomness of the process that Darwin's theory seemed to imply.

In part 2, Dr. Miles describes Darwin's struggle with the problem of natural evil and design in nature.

Darwin’s finches are some of the most visible and recognizable symbols of evolution in the world today. Biology textbooks feature them prominently, and the National Academy of Sciences has enshrined them in the entrance of their headquarters in Washington, DC. Surely the finches that Darwin collected on the Galápagos islands were a central feature of his evolutionary theory, right?

Actually, the Galápagos finches are never even mentioned in Darwin’s famous work On the Origin of Species. Nor do they appear in Darwin’s famous notebooks on “Transmutation of Species”, in which he formulated the idea of evolution by natural selection.¹ Even Darwin’s private diary of his voyage on the HMS Beagle only mentions the Galápagos finches briefly in passing.²

It was only in 1845, in the second edition of The Voyage of the Beagle, that Darwin included a tantalizing sentence about the Galápagos finches:

Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends.³

However insightful this statement may have been, Darwin never published anything else about the Galápagos finches for the rest of his life. Nor did he publically present these birds as direct evidence for this theory of evolution.⁴

If these finches were so important to Darwin’s evolutionary theory, why did he remain silent about them? One of his comments in The Voyage of the Beagle provides us with a clue:

Unfortunately most of the specimens of the finch tribe were mingled together; but I have strong reasons to suspect that some of the species of the subgroup Geospiza are confined to separate islands.⁵

When Darwin was exploring the Galápagos himself in 1835, he had not formulated his theory of evolution yet, and thus he did know what data would be necessary to make definitive conclusions about finch evolution. In particular, he did not keep careful track of which of his specimens came from which islands. Moreover, as was customary among naturalists at that time, Darwin only collected a small number specimens—he brought home only 31 finches and 64 total birds from the Galápagos.⁶

Though Darwin sensed that these birds were truly special, he lacked sufficient evidence to reach any specific conclusions about their evolutionary origins. It would be up to the rest of the scientific community to carry out the necessary empirical research. Subsequent expeditions in 1868, 1891, 1897, and 1905 brought back thousands of Galápagos finch specimens, but instead of unlocking the mysteries of evolutionary theory, the Galápagos finches became a great enigma.⁷

A century after Darwin's voyage, scientists still struggled to explain the staggering variety of finches on this tiny, remote archipelago. By the mid-1930’s, British Museum ornithologist Percy Lowe argued that the finches presented a "biological problem of first class importance", and he told the British Association for the Advancement of Science that the finches displayed a "bewildering diversity, intergradation, and distribution".⁸ Who would be up to the challenge of making sense of such tremendous biological complexity? It was David Lack.

David Lack

Ornithologist David Lack

David Lack had an exceptionally keen eye for bird-watching, and he possessed a passion to match it. By age 15, he had already observed 100 distinct species of birds, and before entering college, authored his first scientific paper. At Cambridge University in the early 1930’s, Lack was disappointed to find that his zoology professors taught “nothing about evolution, ecology, behavior or genetics, and of course nothing about birds.”⁹ In fact, at that time, there were only two professional ornithologists in all of Britain!

Thus David Lack took it upon himself to create his own learning opportunities. As an undergraduate, he became the president of the Cambridge Ornithological Club, traveled to Greenland for a bird-watching expedition, and cultivated a relationship with the prominent biologist Julian Huxley (grandson of Thomas Henry Huxley). Huxley was an inspiring mentor and encouraged Lack to expand his research further by studying tropical birds.¹⁰ Following this advice, Lack embarked on a research trip to Tanzania in the summer of 1934, but his greatest adventure was yet to come.

In 1937, Lack became fascinated by the scientific mysteries surrounding the Galápagos finches. But in order to study their behavior, Lack would need to travel to remote islands halfway around the world. How could he possibly get there? Once again, Julian Huxley was tremendously supportive and raised funds from two prominent scientific societies to pay for his expedition. After a long delay, David Lack and five companions finally set off on their journey.

Instead of residing in comfortable quarters aboard a royal naval ship, Lack’s group subsisted on a shoestring budget, traveled on commercial steamers, and stayed with local settlers. Their experience was definitely not a romantic tale of imperial expedition:

The Galápagos are interesting, but scarcely a residential paradise. The biological peculiarities are offset by an enervating climate, monotonous scenery, dense thorn scrub, cactus spines, loose sharp lava, food deficiencies, water shortage, black rats, fleas, jiggers, ants, mosquitoes, scorpions, Ecuadorian Indians of doubtful honesty, and dejected, disillusioned European settlers.¹¹

Whereas Charles Darwin spent only nineteen days on the shores of the Galápagos, Lack and his crew conducted more than five months of meticulous and exhausting study in the harsh climate. At that time, even the finches themselves provided little solace. Lack wrote,

Darwin’s finches are dull to look at, not only in their orderly ranks in museum trays, but also when they hop about the ground or perch in the trees of the Galápagos, making dull unmusical noises. Only the variety of their beaks and the number of their species excite attention.¹²

The repetitive tedium requisite for important scientific discoveries is rarely discussed in public, and even today many bright-eyed science students become disillusioned by the painstaking work demanded by their Ph.D. programs. But one of the things that distinguishes great scientists is their unwavering commitment and tenacity in completing major projects. David Lack's efforts were not in vain:

"Despite his personal discomforts (or perhaps because of them), Lack did see something on the Galápagos that no one had ever seen before—natural selection at work among its finches through interspecies competition." ¹³

When the birds’ breeding season ended in 1939, Lack was ready to return to his home in England. But the captive finches that he had brought with him fared so badly on the voyage home that he detoured to San Francisco and put them in the care of the California Academy of Sciences. Turning this mishap into an opportunity, Lack stayed there for five additional months to study the Academy’s enormous collection of Galápagos finch specimens.¹⁴

To complete his systematic research, Lack then travelled across the United States to study the Galápagos finch collection housed at the American Museum in New York.¹⁵ Altogether, Lack examined more than 8000 specimens and specifically measured the length, width, and depth of all their beaks.¹⁶

Lack’s final obstacle was in getting his research published. Though he completed his academic manuscript “The Galápagos Finches—A Study in Variation” in 1940, paper shortages during World War II delayed its publication by the California Academy of Sciences until 1945. Were he only interested in making an original contribution to science, Lack could have stopped here and congratulated himself on a job well-done. However, his motivation sprung from a deeper source:

David Lack's drawing of 14 species of Galápagos finches, p. 19 of Darwin’s Finches

"I did not watch birds primarily for scientific reasons but for sheer enjoyment, and from the age of 15 onward returned day after day in a glow of excitement after seeing a new bird or a new habit." ¹⁷

Lack’s joyful fascination with the Galápagos finches inspired him to continue developing his conclusions long after returning from his expedition. While waiting for his academic paper to be published, he began writing a book that would enable students and the general public to share his excitement about these remarkable birds and the evolutionary processes that shaped them.

First published in 1947, Lack’s book became tremendously influential. Before this time, biology textbooks had never even mentioned the Galápagos finches. But after David Lack’s study, the finches became a primary example of evolution by natural selection, specifically adaptive radiation. Not only did textbooks fully rely on Lack’s findings, they also followed his lead in calling them “Darwin’s finches”, the title of Lack’s famous book.¹⁸

Iconic Finches

What was it about these birds that made them such a prominent symbol of evolution? As Darwin himself pointed out, the numerous Galápagos finch populations each have distinctive beaks, and he speculated that they could have evolved from an ancestral species that came to the islands. But a complete picture of finch evolution would have to wait another hundred years, when David Lack arrived.

During his five months on the Galápagos, including both the rainy and dry seasons, Lack observed that these beak differences enable the finches to subsist on different kinds of food:

The beak differences between most of the genera and subgenera of Darwin's finches are clearly correlated with differences in feeding methods. This is well borne out by the heavy, finch-like beak of the seed-eating Geospiza, the long beak of the flower-probing Cactornis, the somewhat parrot-like beak of the leaf, bud, and fruit-eating Platyspiza, the woodpecker-like beak of the woodboring Catcospiza, and the warbler-like beaks of the insect-eating certhidea and Pinaroloxias.¹⁹

Lack's image of beak adaptations from Darwin’s Finches

Specializing in such different sources of food enables these finches to live in close proximity without directly competing with each other or driving populations to extinction. The fact that so many of these closely related finches are able to co-exist is a remarkable fact in itself. As Lack himself put it, “It is not only the origin, but also the persistence, of new species which require explanation.”²⁰

But it is also fascinating to consider how these birds got to be so different in the first place. How did a finch come to have a beak like a “parrot”, “woodpecker”, or “warbler”? The answer lies in the distinct characteristics of the Galápagos. Because the islands are so remote, no actual parrots, woodpeckers, or warblers ever settled on it. In the absence of these species, the Galápagos finches were able to adopt feeding habits and forms that they would never have taken on a large continent full of other birds competing for food. The isolation of these islands offered just the right conditions for us to see living examples of adaptive radiation.²¹

Conclusion

Considering the immense popularity of the Galápagos finches, it is quite surprising to learn that Charles Darwin himself had so little to say about them. In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore. By naming his landmark book Darwin’s Finches,²² Lack paid homage to the man whose voyage on the HMS Beagle helped transform the study of natural history. But at the same time, Lack also obscured the fact that evolutionary biology is an enterprise conducted by a large community of brilliant scholars, not just the product of one man’s efforts.

This tendency to immortalize “great men of science” has also led many people to refer to modern evolutionary theory as Darwinism, despite the fact that it has substantially changed and developed over the past 150 years. It is important to give credit where credit is due, and if that’s the case, we should seriously reconsider how we refer to the Galapagos finches. Evolutionary biologist Dolph Schluter, who studied the finches several decades after David Lack, had this to say:

I find Lack's intuition really stunning given how little information he had. He's my hero actually… They should be called Lack's finches.²³

In the second part of this series, we’ll explore the fact that David Lack, in addition to being a world-renowned evolutionary biologist, was also a devout Christian. His study of evolutionary theory did not cause him to lose his faith; in fact, he actually converted to Christianity after completing his Galápagos finch research.

Author's Note from Joy Walters

As I mentioned in my first post, I grew up skeptical of the whole idea of evolution. One contributor to my disbelief was the lengthy timescale for the “tree of life” that was presented with the theory. I would hear, for example, that dinosaurs lived hundreds of millions of years ago, but there was no explanation of why this was true; it was just given as a fact. No one explained the methods of dating, and so I thought biologists simply estimated the ages of species to fit their preconceived notions of how long it would take for one species to emerge from another. It also seemed like the ages were periodically revised and extended farther back in time, and I figured scientists needed to manipulate numbers to make evolution plausible. This, in my mind, made the theory both unbelievable and dismissible.

Once I learned about the techniques used to date fossils, I realized that my first impressions were wrong; the ancient ages of species are scientific determinations rather than scholarly conjectures. However, I have found in recent conversations that Christians remain skeptical of old ages and the evolutionary time scale. For this reason, I wanted the videocast to address the process of fossil dating (what the methods are and why they are accurate) while focusing on cases where hominid fossils were discovered and dated using these very methods. My hope is that Believers would be informed about the evidence for human evolution and its scientific grounding.

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.

Judging from the flurry of headlines over the past week, one might be tempted to think that proof positive of God’s existence (or lack thereof) had just appeared out of a 27-km-tunnel buried beneath the Swiss-French border. This frenzy of news headlines and blog titles hailed the recent news that CERN’s Large Hadron Collider has discovered a brand new particle of a mass of 125-126 GeV, which is assumed to be the Higgs boson, or the so-called “God particle.” The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity? Is there actually any theological or religious significance in Higgs physics at all?

The short answer is “no,” which becomes apparent when one considers the widely-reported story of how it got named. In 1993, Nobel Laureate physicist Leon Lederman, along with science writer Dick Teresi, wrote a book detailing the history of particle physics starting with Pre-Socratic Greek philosophy Democritus and culminating with the hunt for the Higgs boson. Until this latest discovery, the Higgs boson was the elusive final missing piece of the puzzle known as the Standard Model—a collection of the fundamental particles that constitute our universe and the complex and mathematically-sophisticated relationships between them. Considering how incredibly difficult finding the Higgs boson was proving to be, Lederman wanted to name the book after that “goddamn particle,” according to some of his collaborators. His editor, however, would not allow it and so the name was shortened to “The God Particle: If the Universe Is the Answer, What is the Question?” And thus ‘the God particle’ was born, carrying with it more than enough social baggage for such a miniscule particle.

Particle physicist Dr. Zosia Krusberg (at right) is visiting assistant professor of physics and astronomy at Vassar College and thinks “the term ‘god particle’ is unfortunate. The Higgs boson is no more (or less) divine or spiritually significant than any other elementary particle within the standard model of particle physics.” It may be fundamental to explaining one of the most basic characteristics of the universe—namely the existence of matter and mass in addition to energy—but “it is no more (or less) important than any other physics principle underlying the Standard Model.”

Last week’s discovery was monumental in that it may have finally provided experimental evidence for the Higgs Mechanism and defined the specific energy of the resulting Higgs boson, but even this “breakthrough” for particle physics leaves many scientific questions unresolved. Finding the Higgs boson completes the Standard Model, but it does not do away with many other questions and shortcomings of the current state of particle physics, such as the constituent particles of dark matter, a quantum theory of gravity, and other “mathematically subtle problems.” Not to mention that there is still significant work to be done to determine the exact nature of this newly-found particle. According to Dr. Krusberg, this particle might behave just as the Standard Model predicts or it could instead be “a Higgs-like particle that will serve as a gateway into explorations of physics beyond the Standard Model." Krusberg continued, “And I guarantee that it is this latter scenario that most of us are hoping for: physicists love nothing more than discovering the shortcomings of their theories, since this is the first step toward more fundamental theories with even more predictive power!”

No, finding the Higgs boson does not answer all the questions of particle physics, much less lend insight into the existence (or not) of God. For that reason, Dr. Krusberg (like most physicists) bemoans the term ‘God particle’ and insists, “There really is nothing either literally or metaphorically god-like about the Higgs boson.” Indeed, one writer for the British journal The Guardian reached such a point of frustration about the name that he ran a competition for alternatives. The winner was “the champagne flute boson,” ostensibly because the bottom of a champagne bottle is an excellent and oft-used demonstration of the energy potential of the Higgs Mechanism. Or then again, perhaps it is simply because physicists thought that finally finding this shy particle would call for some of the bubbly.

On the other hand, some science writers and scientists can appreciate the ‘educational benefits’ of such a mysterious and controversial name because it attracts the attention of the general public and puts a relatable face on an extremely esoteric physics concept. Krusberg herself admits that “People are naturally drawn to the mysterious and the controversial, providing educators with great teaching opportunities.” But she worries about the larger social implications involved in “mixing the vernacular of physics and spirituality,” not least because such uncritical mixing can lead the non-scientific community to draw conclusions about the authority and reach of science that are not justified.

Understanding that the Higgs boson is not the literal stuff of God and that it does not prove or disprove God’s existence (as the name seems to suggest) extinguishes the fire under any sort of religious outcry. But this does not mean that its discovery is irrelevant to the discussion of science and faith, nor to the Christian community as a whole. As Dr. Krusberg remarks, “The recent discovery of [this] new boson at the LHC perfectly embodies the scientific process at its best (and thereby illustrates to the public why and how science works).” Scientific exploration of nature is not a fool-proof endeavor; healthy skepticism and accountability to a wide community of other researchers are absolutely critical to its success. But such evidence of the power and finesse of well-executed science as we saw last week is a testament to our ability to explore and understand the ‘how’ of the universe. God has equipped humanity with the desire, the intellectual abilities, and the collective will to recognize and explore the cosmic order and beauty of his creation. God has made our home knowable, and has given us the tools and capacities by which to know it.

It is valuable, then, for the Christian community to understand and appreciate how science works, in part to recognize that there are many instances in which science and the church work in tandem in order to better understand and better serve the world. But I think there is something else we can draw from the story of the Higgs boson, too. The nickname ‘the God particle’ has touched nerves in religious communities because it implies that science has the ability to prove or disprove divine existence by physical means. Even though the physics community is by no means claiming insight into the divine, it is sometimes assumed by the religious community that scientists view their work as chipping away at God’s existence when they begin to understand something that was previously unknown, or known only “by faith” in esoteric theories and models.

And yet, regardless of motives or metaphysical interpretations, perhaps physicists' search for the Higgs boson is in fact an apt picture of our own search for God. How many times have we stared up at the starry ceiling in times of crisis and prayed fervently for some kind of sign from God to assure us of his presence? And how many times has that much-desired evidence appeared only in retrospect, when we look back to see God’s hand faithfully and elegantly working in ways inscrutable at the time? It took a community of physicists to discern the presence of the Higgs boson. But even so, they could only do so after the fact from the cascade of particle decays it sparked; they could not observe the particle itself directly. In a similar way, though we often do not see the working of God directly, “in the moment,” we still trust in his presence and providence, often depending on friends, family and the community of the church to help us see his hand in hindsight.

So while the discovery of the Higgs boson does not itself explain God, we rejoice at the subtle yet striking new insight we have into God’s creative genius via the Higgs boson and at the way God gives evidence of his faithfulness in the ordered creation itself. Perhaps, however, the greatest insight we can glean from this breakthrough is an analogy for the way God calls us to seek him and find him together, in the community of those who follow his son.

Tomorrow, Baylor University physicist Gerald Cleaver answers the question, "What is the Higgs boson?"

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.

I recognize the objection here of William Hasker and the idea of emergentism, or emergent dualism, in which a distinct soul or self emerges from the complex configurations of the biological organism, similar to magnetic fields generated by physical objects but distinct from them. See Hasker, The Emergent Self (Ithaca, NY: Cornell University Press, 1999), for the fullest presentation of his view. The difficulty of his view lies in attributing to material stuff the power to generate a non-material reality. This difficulty is raised by Alvin Plantinga (see n. 5 below) and others and emergent dualism is as of today still a minority view in philosophical circles.
