These are tough questions, and Arends provides some helpful insight on how she’s handled them with her own kids.

So much for signs of Mind. Where are we to look for signs of Purpose? Before 1859, the answer would have been obvious: in the marvelous adaptation of life to its environment. Charles Darwin, by the publication of The Origin of Species, presented us with natural selection as a patient process by which such marvels of “design” could come about, without the intervening purpose of a Designer being at work to bring them into being. At a stroke, one of the most powerful and seemingly convincing arguments for belief in God had been found to be fatally flawed. Darwin had done what Hume and Kant with their philosophical arguments had failed to achieve, abolishing the time-honored form of the argument from design by exhibiting an apparently adequate alternative explanation.

Since then, two important developments have taken place. One is the realization in the late 1920s that the universe itself has had a history and that notions of evolving complexity apply not only to life on Earth, but to the whole physical cosmos. The other is the acknowledgement that when we take this cosmic history into our reckoning, evolution by itself is not sufficient to account for the fruitfulness of the world. Let me explain.

A convenient slogan-encapsulation of the idea of evolution is to speak of it as resulting from the interplay of chance and necessity. “Chance” stands for the particular contingencies of historical happening. This particular cosmic ripple led to the subsequent condensation of this particular group of galaxies; this particular genetic mutation turned the stream of life in this particular direction rather than another. “Necessity” stands for the lawfully regular environment in which evolution takes place. Without a law of gravity, galaxies would not condense; without reasonably reliable genetic transmission, species would not be established. What we have come to understand is that if this process is to be fruitful on a cosmic scale, then necessity has to take a very specific, carefully prescribed form. Any old world will not do. Most universes that we can imagine would prove boring and sterile in their development, however long their history were to be subjected to the interplay of chance with their specific form of lawful necessity. It is a particular kind of universe which alone is capable of producing systems of the complexity sufficient to sustain conscious life.

This insight, called the Anthropic Principle, has given rise to much discussion. [Polkinghorne cites John D. Barrow and Frank  J. Tipler, The Anthropic Cosmological Principle; John Leslie, Universes and his own Polkinghorne, Reason and Reality, chap. 6, and Beyond Science, chap. 6.] Is it no more than a simple tautology, saying that this universe which contains ourselves must be compatible with our having appeared within its history? For sure that must be so, but it is surprising—and many of us think significant—that this requirement places so tight a constraint on the physical fabric of our world. Although we know by direct experience this universe alone, there are many other possible worlds that we can visit with our scientific imaginations, and almost all of them, we believe, would be infertile.

Sometimes the Anthropic Principle is also called the Goldilocks Principle: if all of the physical conditions were not “just right,” there could be no life whatsoever in the universe (source: http://home.netcom.com/~swansont_2/goldilocks.jpg)

John Leslie, who has given a detailed account of the many processes that depend on the precise character of physical law for their ultimately life-generating effects, has also given a careful discussion of what conclusions we might draw from the Anthropic Principle. [Leslie summarizes his position at here.] We are in a realm of discourse where such conclusions depend on the judgment that we have attained a deeper and more comprehensive understanding, rather than that we have deduced a logically unassailable consequence. Leslie believes that it is no more rational to think that no explanation is required of fine anthropic coincidences than it would be to say that my fishing apparatus can accept a fish only exactly 23.2576 inches long and, on casting the rod into the lake, I find that immediately I have a catch, which is simply my good luck -- and that’s all there is to say about it. The end of the matter for Leslie is: “My argument has been that the fine tuning is evidence, genuine evidence, of the following fact: that God is real, and/or there are many and varied universes. And it could be tempting to call the fact an observed one. Observed indirectly, but observed none the less.” [Quoting Leslie, Universes, p. 198. The fishing example is on pp. 9-13 in the same book.] Either there is one world whose fruitful potential is the expression of divine purpose or there are many worlds, one of which just happens to be right for the evolution of life.

Those who wish to avoid any suggestion of a divine purpose manifested in the fruitful fine tuning of physical law will have to opt for the second of Leslie’s alternative explanations. [Here Polkinghorne has a note: “A theist could, of course, combine the two options, but personally I find that unappealing.”] There are a variety of ways in which one might conceive of the existence of such a portfolio of different universes, understood as domains in which different laws of nature are operating. The more plausible accounts will seek to make some appeal to scientific knowledge and will not just rely on the ad hoc assumption that there are a lot of separate worlds that just happen to exist.

Many-worlds quantum theory will not do the trick (even if one believed in it, which I do not), for its parallel worlds are simply ones in which quantum events have different specific outcomes and the basic laws of nature are common to them all. [Polkinghorne cites The Quantum World, pp. 67-68, and Alastair. Rae, Quantum Physics: Illusion or Reality?, chap. 6.] Modern ideas about symmetry breaking offer a little more scope. If there is a Grand Unified Theory of the fundamental forces of the universe, then the particular forces that we actually observe, and which are the concern of the Anthropic Principle, will have crystallized out from this highly symmetric ur-state very early in cosmic history, as expansion cooled the world below the relevant transition temperature. The precise details of this symmetry breaking, and the consequent precise force ratios resulting from it, are spontaneously generated through the amplification of tiny random fluctuations. This process need not be literally universal, and the cosmos may be split into vast domains in which different consequences have been realized. The universe observable by us might be a part of one such huge domain, and, of course, in our particular neck of the woods, the force ratios are “by chance” compatible with our evolution. This account is speculative, but motivated, and I am inclined to consider its possibility as far as it goes. That, however, is not very far. One still needs the right sort of Grand Unified Theory for all this to be feasible, and in that respect our universe is still very special compared to the totality of universes that we can imagine.

Moving up on the scale of bold speculation, one might evoke notions of quantum cosmology which suggest that universes of various kinds are continually appearing as a physical process called inflation blows up microworlds, which have bubbled up as quantum fluctuations in some universal substrate. [Here Polkinghorne has a note: “The quantum vacuum is an active medium owing to fluctuation effects.”] Proponents of this point of view are sometimes moved to describe our anthropic universe as being “a free lunch.” The phrase itself should trigger a cautious evaluation of the offer being made. The cost of this particular cosmic meal is the provision of quantum mechanics itself (a classical Newtonian world would be a perfectly coherent possibility, but a sterile one), and just the right quantum fields to fluctuate in order to produce first inflation and then all the necessary observed forces of nature. This idea is less well established scientifically than the domain option and, in any case, it does not really remove anthropic particularity, for the basic physical laws still have to take certain specific forms which are the necessary foundation of the proposed quantum cosmology.

Beyond this point, speculation becomes rapidly more rash and more desperate. Maybe, the laws of nature themselves fluctuate, so that a vast portfolio of conceivable, or (to us) inconceivable, worlds rise and fall in the relentless exploration of random possibility—occasional patches of transient and varied order in a sea of seething chaos. We have moved far beyond anything that could be called scientific in this exercise of prodigal conjecture. It is time to consider Leslie’s other alternative: that there is a divine purpose behind this fruitful universe, whose fifteen-billion-year history has turned a ball of energy into the home of saints and scientists, and that this purpose has been at work in just one world of consistent physical law (though maybe with domains of different expressions of that law).

Once again the theistic conclusion is not logically coercive, but it can claim serious consideration as an intellectually satisfying understanding of what would otherwise be unintelligible good fortune. It has certainly struck a number of authors in this way, including some who are innocent of any influence from a conventional religious agenda. [Polkinghorne cites two books by Paul Davies, God and the New Physics, and The Mind of God; Hugh Montefiore, The Probability of God; and his own Science and Creation, chaps. 1, 2; and 4.] Such a reading of the physical world as containing rumors of divine purpose, constitutes a new form of natural theology, to which the insight about intelligibility can also be added. This new natural theology differs from the old-style natural theology of Anselm and Aquinas by refraining from talking about “proofs” of God's existence and by being content with the more modest role of offering theistic belief as an insightful account of what is going on. It differs from the old-style natural theology of William Paley and others by basing its arguments not upon particular occurrences (the coming-to-be of the eye or of life itself), but on the character of the physical fabric of the world, which is the necessary ground for the possibility of any occurrence (it appeals to cosmic rationality and the anthropic form of the laws of nature). [For some historical comments on this approach to natural theology, see here.]

This shift of focus has two important consequences. The first is that the new-style natural theology in no way seeks to be a rival to scientific explanation but rather it aims to complement that explanation by setting it within a wider and more profound context of understanding. Science rejoices in the rational accessibility of the physical world and uses the laws of nature to explain particular occurrences in cosmic and terrestrial history, but it is unable of itself to offer any reason why these laws take the particular (anthropically fruitful) form that they do, or why we can discover them through mathematical insight. The second consequence of this shift from design through making to design built into the rational potentiality of the universe is that it answers a criticism of the old-style natural theology made so trenchantly by David Hume. He had asserted the unsatisfactoriness of treating God’s creative activity as the unseen analogue of visible human craft. The new natural theology is invulnerable to this charge of naive anthropomorphism, for the endowment of matter with anthropic potentiality has no human analogy. It is a creative act of a specially divine character.

“Création ex nihilo,” from Charles de Bouelles, Libellus de nihilo (1510). God “inspires” (breathes or blows into) the universe, creating it out of nothing (ex nihilo).

Looking Ahead

In the next excerpt, Polkinghorne turns his attention from physics and teleology to biology and theodicy. Look for it in a couple of weeks.

These were just a few of the questions that motivated us at BioLogos to commission a survey of pastors on origins.  In 2012, the Barna Group conducted 743 telephone interviews with pastors from across the US, from churches big and small, and from all Christian denominations.  This comprehensive, in-depth survey provides a fascinating analysis of views held by clergy today.   In the coming month, we’ll be digging deeper into the survey results, but for now, here are some key highlights:

#1: Pastors hold a diversity of views on origins.

Overall, while a slight majority of the pastors surveyed fall under the label of Young Earth Creationism (54%), sizeable portions of clergy accept Progressive Creation (15%) and Theistic Evolution (18%).

The numbers varied widely based on a number of factors, however. Pastors of mainline churches were most likely to accept Theistic Evolution, while non-Mainline, Charismatic, and Southern Baptist pastors were overwhelmingly Young Earth Creationists. Pastors of larger churches were also more likely to accept Theistic Evolution.

Regionally, the highest percentage of YEC pastors was found in South, while the highest percentage of pastors accepting TE was in the Midwest. Pastors from the western states were the least likely to accept TE.

#2: Most pastors think science and faith questions are important.

Regardless of their views, the majority of pastors surveyed feel that the Church needs to look at how it handles issues of science. 72% of pastors with YEC views and 73% of pastors with TE views agree with the statement that “the Christian community needs to take a serious look at its understanding of science and human origins in order to maintain its witness in the world.” (The numbers are slightly lower for pastors who hold to Progressive Creation and who are uncertain).

Similarly, 66% of YEC pastors and 61% of both TE and Progressive Creation pastors agree that “younger adults today are more concerned than ever about whether faith and science are compatible.”

#3: Clergy think disagreements on science and faith harm our witness (but for different reasons).

Clergy across all three viewpoints feel that disagreements are harming the Church’s outreach, but they differ in how they view that harm.

YEC pastors overwhelming agreed (85%) that “Christian disagreement on matters of creation and evolution is compromising our witness to the world.” However, a majority of TE pastors disagreed with the statement (63%).

Conversely, a majority of TE pastors (63%) agreed that “The church’s posture toward science prevents many non-Christians from accepting Christianity,” while a majority of YEC and Progressive Creation leaning pastors disagreed (59%).

#4: Pastors aren’t avoiding science.

The majority of pastors think that addressing issues of science for their congregations is an important part of their work. Of those surveyed, 72% felt that addressing science issues in the local community was somewhat (51%) or very (21%) urgent. When asked about science on a national and global level, even more pastors felt that addressing science issues is important (43% somewhat and 46% very). Furthermore, 79% of pastors included scientific themes in at least one sermon in the past year, and 40% had included them in at least ten sermons.

The majority of clergy across all four viewpoints also agreed with the statement “Just as scripture should influence human interpretation of science, science should also inform our understanding of scripture.” The numbers were highest for TE pastors and those who are uncertain (81% and 72%, respectively), though over half of YEC and PC pastors also agreed (52% and 65%, respectively).

Finally, although YEC’s are more reluctant than other pastors to say “science should inform understanding of scripture, they strongly agree (84%) that “The Christian community needs a greater commitment to showing how young earth creationism is consistent with science.”

#5: However, they are concerned about evolution for biblical reasons.

Over half of pastors said they had “major concerns” about the idea that God used evolution. The main reasons for that concern were that the idea “undermines the authority of Scripture” (64%), “views portions of the Bible as non-literal, like Genesis” (62%), “raises doubts about a historical Adam and Eve” (61%), and “raises questions about how and when death and sin entered the world” (59%). However, 26% of pastors saw no concern with the idea that God used evolution.

#6: The majority of clergy accept parts of scripture as symbolic.

60% of the pastors surveyed felt that “some portions of the Bible are symbolic, but all that it teaches is authoritative.” Clergy whose views fall under theistic evolution and progressive creation were more likely to accept this statement (79% and 73% respectively), but a sizeable number of YEC pastors (40% among the core followers and 49% among those leaning towards YEC) also agreed with the statement.

#7: Clergy are concerned that changing their views on origins might compromise their ministry.

Over half of pastors (58%) who fell under the YEC category agreed that “If you publicly admitted your own doubts about human origins, you feel you would have a lot to lose in your ministry.” 41% of pastors in the Progressive Creation group also agreed with the statement. Pastors who were uncertain or who fell under the Theistic Evolution group were less concerned, with only 26% and 17% respectively agreeing with the statement.

Evidence from the Size of the Universe

We’ve already discussed the vastness of the universe earlier in this chapter. We noted that the most distant galaxies are over 10 billion light years away, indicating that the light left these galaxies over 10 billion years ago in order to reach us today. The straightforward interpretation of these data is that the universe must be at least 10 billion years old.

While some people have argued that perhaps these galaxies aren’t really that far away, all of the methods used to measure distance agree that galaxies are billions, not thousands, of light years away. Others have argued that perhaps the light moved much faster when it first left these galaxies, so that it could reach us in much less time than 10 billion years. But this idea conflicts with other data that we have. As described in Chapter 3, ample evidence supports the idea that physical processes such as quantum mechanics and electromagnetism function the same way in distant galaxies as they do on earth. Those physical processes depend on the speed of light and would look very different if the speed of light had changed. Instead, they look the same in distant galaxies as they do on earth, indicating that the speed of light has been constant over the history of the universe.

Evidence from the Moon and Planets

Studies of the Moon and planets also give evidence for great age. Geologists can use some of the same methods to measure the age of rocks on the Moon, Venus, and Mars as they use on Earth. That’s because the asteroid collisions, volcanoes, and erosion they observe on Earth also occur on the Moon and planets. Photos taken by spacecraft while orbiting Mars show channels and gullies on the planet’s surface. Similar channels on Earth are usually made by flowing water. Yet there is no liquid water on the surface of Mars right now.

What does this have to do with age? It is evidence that Mars was much different in the past than it is today. The atmosphere used to be much thicker and warmer, similar to Earth’s, but now it is much colder and thinner. This dramatic change in planet-wide climate took millions or billions of years. Thus the rocks testify that the planet Mars must be at least this old.

Evidence from the Orbits of Asteroids

The orbits of asteroids also show evidence of a long history. When an asteroid is discovered, its path through the sky shows its orbit around the Sun. Once astronomers know the orbit of an asteroid they can calculate its orbit in the past and into the future to see whether it will hit the earth. By calculating the orbits backward, astronomers have found several asteroids that converged at the same location several million years ago. Apparently two larger asteroids collided at this spot and shattered into the smaller asteroids we see today. If God had created asteroids just a few thousand years ago, why would he have put them in orbits that suggest a collision several million years ago? The evidence clearly points to a long history for asteroids.

Evidence from Meteorites

Radiometric dating is used to study rocks on Earth as well as rocks from elsewhere in the solar system. Studies have been done on the rocks that astronauts brought back from the Moon and on asteroids that have fallen to Earth. As with Earth rocks, scientists use multiple radioactive isotopes to cross-check age measurements. At least three different isotopes have been used to measure the age of Moon rocks, and at least five different radioactive isotopes have been used to measure the age of meteorites. The results all agree: the oldest Moon rocks and asteroids are 4.6 billion years old. This is our best measure of the age of the solar system as a whole. The universe itself must be at least this old.

Evidence from Star Clusters

Another important measure of age in the universe comes from star clusters. Because all stars in a star cluster form in the same nebula at about the same time, they all have about the same “birthday.” But they don’t all have the same lifespan. High-mass stars burn bright and fast like a “flash in the pan,” while low-mass stars burn slowly and steadily. Consider how this will look in a star cluster. A cluster starts with many stars with the same birthday but of all different masses. Over time the high-mass stars die off first, leaving behind the low-mass stars. This means that if many high-mass stars are present, the cluster must be young because they haven’t burned out yet. If most of the stars are low-mass, the cluster must be old. Careful studies of star clusters show that some clusters are younger and some are older, with the oldest ones having an age of about 12 billion years.

Multiple Lines of Evidence

The most distant galaxies, the planets and asteroids of our own solar system, and the oldest star clusters all are several billion years old. Astronomers have many different methods for measuring the age of various objects, and they all support ages of billions of years, not thousands. Even if the assumptions of one or two methods were faulty, it is highly unlikely that all of the methods would be affected. Like the geologists in the 1700s, astronomers today have found multiple lines of evidence against a young earth and young universe.

It may seem as though we are once again describing a conflict between science and theology. Scientific results that indicate great age do conflict with the Young-Earth Interpretation of Genesis 1 discussed in chapter 5. But remember that in chapters 5 and 6 we presented many other interpretations of Genesis 1; several of these are not in conflict with the great age found in the book of nature. In chapter 6 we also explained why we believe that the best biblical scholarship, quite independent of modern science, indicates that Genesis 1 was never meant to convey scientific information to the original audience. Its intent for the first listeners, and for us, is to teach the who and why of creation, not the how and when. Taken in this context, there is no conflict between Genesis 1 and the astronomical evidence for great age.

As is the case in many fields, astronomers are trying to settle questions that the general public thinks little about, often because laypeople are still coming to grips with much more basic questions such as Did the universe appear—poof—all at once or did it evolve into its present state?

These are questions where science crosses into—and sometimes crosses swords with—religion. For many who take an anti-evolutionary stand as a matter of spiritual principle, the word evolution should not be applied to anything having to do with creation, cosmic or otherwise. Yet, if an evolving universe implies a beginning (and it does, for relativistic reasons), science has taken a tremendous leap toward rapprochement with Christian faith on the matter of creation. Traveling backward in time with their shrinking subject, cosmologists can only watch the cosmos disappear at the beginning, pointing to a universe that came out of nothing—a universe that wasn’t there.

No one need ask: “Were you there?” Chuck Steidel has tapped into nature’s own motion picture of past events, now showing in the present. Anyone who cares to view it can now see for himself what was and wasn’t there, at various stages of the deep past.

While other astronomers at first assumed that larger telescopes would be necessary before finding truly primeval galaxies, Steidel began finding dozens of them—and today, thousands of them. His method, called ultraviolet dropout, is based on the fact that intergalactic hydrogen gas absorbs the ultraviolet light of the most distant galaxies, causing them to disappear when seen through an ultraviolet filter. Steidel identified early galaxies that are present in pictures of the cosmos when viewed through red and green filters, but that aren’t there when viewed through an ultraviolet filter.

Visual evidence for a universe that isn’t there starts with the observation of galaxies that aren’t there.

“The way that people have looked for these in the past tended to be looking for particular, spectacular fireworks of stars going off all at once,” Steidel told me. He was only 32—a young-looking 32—and could have passed more easily as a student than as a professor as he talked with me in his Caltech office, surrounded by Hubble Deep Sky images. “So they were looking for relatively rare events, using narrow-band filters tuned to find an emission line that comes from hydrogen atoms. And you have to have the filter exactly tuned to that wavelength to see it.”

“And I’ve heard it’s like trying to find a needle in a haystack,” I offered.

“It’s much more difficult.”

“So rather than try to find something that stands out you’re trying to find something that drops out?”

“That’s correct. It’s a very simple technique, where we take pictures through different filters, very deep images of the sky with CCD detectors, and we take three filters, and we look for objects that are present through two of those filters, and they completely disappear in the third. And the reason they disappear is because they’re at a high redshift.”

The high redshift denotes greater distances—and earlier periods, because of the time required for light to reach us from those greater distances. These young galaxies contain young, hot stars, emitting strongly in the ultraviolet. However, ultraviolet radiation from the most distant galaxies is absorbed by a greater amount of intervening hydrogen gas along the way. Today, Steidel uses the 200-inch Hale Telescope at California’s Palomar Observatory to find these primeval galaxies with his ultraviolet dropout technique, then flies to the 10-meter Keck telescope in Hawaii to measure their redshift, which corresponds to their distance and time period.

And what do these galaxies look like?

“We actually think we’re seeing the central bulge regions of galaxies forming,” said Steidel, “that is, the round part in the middle of a spiral or an elliptical galaxy, where you expect all of the star formation to be happening in a relatively small region. And those parts of galaxies we see today are also the parts that we think are the oldest stars in those galaxies.”

“And you’re saying that modern galaxies have the oldest stars in the bulges, is that right?”

“That’s right …. It’s still somewhat controversial. But there isn’t any doubt that we’re finding a number of things that match fairly closely to the number that you would expect to find if you were looking at the progenitors of the present-day, bright galaxies.”

Steidel’s galaxy surveys have shown that galaxies were already arranged in clusters at that early time. But the individual, primeval galaxies lacked the characteristics of today’s spirals and ellipticals. More recently, Steidel has focused on a slightly later period, from about 10 to 12 billion years ago, when star formation appears to peak. If seeing is believing, then, as Steidel says, the universe “has absolutely changed with time.” His methods have helped astronomers identify populations of galaxies at various stages, where their differences from one to another are unmistakable.

In the years ahead, telescopes beyond our obfuscating atmosphere, like NASA’s James Webb Space Telescope (collecting six times as much light as the Hubble), may begin to give us glimpses of the “Dark Ages,” when the first galaxies began to form. As our improving technologies bring us closer to the beginning, they will lead people to ponder, once again, what happened before that. 

In my interviews with researchers, I usually bring up such crossover questions when the scientists or their studies naturally suggest them. But I worried that I’d crossed over too clumsily into this territory with Steidel when I asked him what he thought about a universe that appeared to come into being out of nothing.

He hesitated and said, “What happened before, you know, it’s …” and his voice trailed off. 

Finally I suggested: “Something must have happened before.”

“I think about that extremely rarely.”

Shoot, I’d gone too far, I thought.

But then he added: “On the other hand, I do have a very wide appreciation for whatever put things there—because it’s just the greatest thing to go out on the catwalk around the dome, in the middle of the night, and just look up there, or look at a picture of the Hubble Deep Field, and see all the things that are out there, and—you know— it’s a beautiful universe out there.”

Indeed, come to think of it, the way it all came together may be an even more impressive fact to ponder than the fact that at one time, that is, before time, the universe wasn’t there.

In this video Conversation, Denis Alexander addresses two prominent barriers for Christians to accept evolutionary creation. The first is Biblical interpretation. When contemporary Christians interpret the early chapters of Genesis literally, they do so out of a desire to take the text seriously. Yet the early church fathers saw these chapters as figurative—and that figurative interpretation did not lesson the important foundational truths taught in these passages. The contemporary literal reading is actually a modern approach to the text in that our scientific mindset inappropriately shapes the interpretation. Since science did not even exist at the time that Genesis was written, an overly literal interpretation can actually cause us to miss the inspired message that the Biblical authors were communicating.

The second barrier is the rhetoric of the New Atheists, who claim that it is impossible to accept evolution while still believing in God. Christians should challenge this. Traditional Christian views are not in conflict with modern science. Instead, they see nature as God's work, with St. Augustine writing that "nature is what God does." As humanity develops a scientific understanding of nature, we will only learn more about the handiwork of God. 

Grantees will benefit from in-person interaction through a series of summer workshops in 2013, 2014, and 2015. These meetings will not only foster a broader knowledge base, but will build a sustained network of scholars and church leaders, both young and seasoned, who are serious about addressing the concerns of the church about evolution. Also in 2015, in connection with the third summer workshop, BioLogos will host a large conference open to scientists, scholars, and church leaders from around the world.

ECF History

In January 2012, BioLogos was awarded a multi-million dollar grant from the John Templeton Foundation to fund the work of scholars and church leaders on evolution and Christian faith. In spring 2012 we worked hard to get the word out. You may have seen announcements on the BioLogos website, in our newsletters, on the Books & Culture, Leadership Journal, or First Things websites, on your professional society’s listserv, or perhaps on your friend’s blog.

The response was overwhelming: we received 225 letters of intent for a total request of $21 million—about seven times the amount we had to offer. We needed to invite the most promising applicants to submit a full proposal, but recognizing the projects with highest potential would require broad expertise. From the beginning, we envisioned that a panel of scientists, pastors, and scholars would oversee the application and review process as well as play key advisory roles throughout the project. A team of eight highly qualified individuals came on board in the early months of the project. They reviewed each proposal and together recommended that BioLogos invite 86 applicants to submit full applications.

The deadline for submissions was October 1, 2012. As in the previous round, the ECF panel evaluated each proposal. In addition, we asked 55 other experts to participate, so that each proposal received 3-4 scores. Criteria for the decision included significance of topic, project design, creativity and innovation, long-term impact potential, feasibility, and budget.

The panel then met together November 29-30, 2012, to make the final funding decisions. In the end, they recommended that BioLogos give 37 awards, ranging from $23,000 to $300,000. BioLogos staff notified applicants of their awards on December 14, 2013.

The Grantees

As part of our objective to create a network of scholars and leaders, we awarded grants to organizations across the U.S. and the world. Thirty of the 37 grantees are domestic; seven are international, hailing from Canada, France, Great Britain, Netherlands, and Spain.

Two-thirds of the accepted projects will be led by teams—some with three or more Project Leaders. We expect that the teamwork and time spent together at our summer workshops will be the start of a long-lasting network of people dedicated to helping the church think carefully about origins.

Applicants chose to apply under one of three program tracks: interdisciplinary scholarship (Track 1), intra-disciplinary scholarship (Track 2), and translational projects (Track 3). Track 1 projects focus on both the collaboration between individuals in different disciplines and the development of projects at the interface of different content areas. Track 2 projects focus on work done within a specific discipline. Track 3 focuses on projects that encourage Christians, especially those within more conservative traditions, to engage in meaningful and productive dialogue to reduce tensions between mainstream science and the Christian faith. The numbers of grantees in Tracks 1, 2, and 3 are 6, 8, and 23, respectively.

Many of the scholarly projects tackle questions about Adam and Eve, the Fall, human identity, and Original Sin—some of the most critical interpretive issues for evangelical theology.  Some examples: 

• Theologian Oliver Crisp of Fuller Seminary will take an analytic theology approach to ask to what extent a theological account of the origin of human sin depends upon the evolution of modern humans from one and only one ancestral pair—especially if that pair does not appear to correspond to what we would think of as modern human beings. 

• Pastor Michael Gulker and philosopher James Smith, leading a large team from The Colossian Forum, ask a related question: if humanity emerged from non-human primates—as genetic, biological, and archaeological evidence seems to suggest—then what are the implications for Christian theology’s traditional account of origins, including both the origin of humanity and the origin of sin? 

• Biologist Dennis Venema of Trinity Western University and New Testament scholar Scot McKnight of Northern Seminary will write a book on the evidence for evolution and population genetics, with informed theological reflection on how these issues interact with orthodox Christianity.

• Biologist David Wilcox of Eastern University will develop an updated model of human identity which reflects the complex recent scientific advances in genetics and paleoanthropology and yet is sensitive to theological concerns.  

These are just a few of the scholarly awards; check out the Grantees page for full descriptions of all Track 1 and Track 2 projects.

All projects have translational potential, but Track 3 projects are designed to meet the needs of a particular constituency within the evangelical church. These projects run the gamut from ethics to education to media production to ministry resources.  Some examples include:

• Theologian Lee Camp of Lipscomb University will produce “The Questions in Monkey Town,” an episode of Tokens, a live variety show that features musical performances, comedic sketches, brief interpretive monologues, and dialog with authors and scholars. The episode will be performed and filmed on the site of the famous Scopes Trial in Dayton, Tennessee.

• Chaplain Joshua Hayashi and Educator Diane Sweeney of the Punahou School in Hawaii will lead a team to produce multimedia curricula aimed at helping high school students connect with their biology curricula and, at the same time, deepen their Christian faith.

• Physics teacher and pastor Benoît Hébert of Science et Foi Chrétienne in France will lead an international, multi-denominational team of French speaking Evangelical scientists, pastors and church leaders to produce a large number of resources on evolutionary creation.

• Pastor Seung-Hwan Kim of Grace Truth Community Church, a Southern Baptist church in Cambridge, Massachusetts, will produce teaching and preaching materials about evolution for church leaders.

• President Gregory Wolfe and Director of Resource Development for IMAGE will gather artists and writers of faith whose work explores the dialogue between evolutionary science and faith practice, convening a conversation between them and scientists, theologians, and church leaders in private and public conferences.

Again, this is just a taste of the diversity of Track 3 projects. Read more about each project on the Grantees page. You can look forward to an incredible variety of resources coming out of the ECF program, many of which will be featured right here on the BioLogos Forum.

For many American evangelicals it will come as a surprise to realize just how little Lewis thought was at stake in the scientific question of our biological origins. As we have seen, Lewis had no objection to the notion that “man is physically descended from animals.” Four years after admitting to being shaken by some of the writings from Bernard Acworth’s Evolution Protest Movement, Lewis could still write in a private letter, “I don’t mind whether God made man out of earth or whether ‘earth’ merely means ‘previous millennia of ancestral organisms.’ If the fossils make it probable that man’s physical ancestor’s ‘evolved,’ no matter.”¹ So far as we can tell, Lewis never took the view that belief in mere Evolution, “Evolution in the strict sense,”² “the Evolution of real biologists,” which he took to be “a genuine scientific hypothesis” and “a purely biological theorem”³ was necessarily at odds with a belief in mere Christianity.

Indeed, the final chapter of his classic book Mere Christianity, “The New Men,” assumes an evolutionary picture of life’s origins and development throughout.⁴ He writes,

Perhaps a modern man can understand the Christian idea best if he takes it in connection with Evolution. Everyone knows about Evolution…: everyone has been told that man has evolved from lower types of life.⁵

While Lewis acknowledges that “some educated people disbelieve [the theory of Evolution],” he gives no hint throughout the rest of the chapter that he is one of their number.⁶ In fact, throughout the rest of the chapter he seems to simply assume a broadly evolutionary picture of natural history (as he does in The Problem of Pain and elsewhere). So, for instance, he writes:

Thousands of centuries ago huge, very heavily armoured creatures were evolved.⁷

At the earlier stages living organisms have had either no choice or very little choice about taking the new step [of development]. Progress was, in the main, something that happened to them, not something that they did.

Century by century God has guided nature up to the point of producing creatures (humans) which can (if they will) be taken right out of nature, turned into “gods.”⁹

And he says much more in that vein. While it may be possible to read Lewis as invoking Evolution for purely illustrative purposes without actually believing in it, such a reading seems less than likely given his statements in this chapter and elsewhere. In fact, Lewis offers no hint anywhere in his public writings that he regards evolutionary theory as either untrue or conflicting with mere Christianity.

What Lewis did believe to conflict with Christian faith was what he called the great “Myth” of “Evolutionism” or “Developmentalism.” But this is not the same as evolutionary theory per se. “[We] must sharply distinguish between Evolution as a biological theorem and popular Evolutionism or Developmentalism which is certainly a Myth,” he writes in his essay “The Funeral of a Great Myth.”¹¹ Lewis believed that the great myth of “Evolutionism” conflicted not only with the Christian faith, but with Reason itself, undercutting the grounds for believing in human rationality and, therefore, in any human rationale that could be offered for believing in Evolutionism in the first place. According to Lewis,Evolutionism’s chief premise, namely, Naturalism, invalidates human reasoning itself, amounting to “an argument which proved that no argument was sound—a proof that there are no such things as proofs—which is nonsense.”¹² “All possible knowledge…depends on reasoning,” he writes in chapter III of Miracles.¹³ “We infer Evolution from fossils: we infer the existence of our own brains from what we find inside the skulls of other creatures like ourselves in the dissecting room.” All sciences, including evolutionary science, depend upon the validity of human inference for their own validity. “Unless human reasoning is valid no science can be true.”¹⁴ Naturalism, however, with its grand Myth of Evolutionism explains all of reality, including human reason, in terms of non-rational natural causes and effects, reducing all human reasoning to being no more than the accidental byproducts of chance, matter and time, and thereby undercutting the validity of reasoning itself.

However, if one allows, as Lewis apparently did, that God guided the evolution of humanity so as to make us reasonable creatures, then humanity’s descent from the animals in no way undermines the validity of human reasoning. By maintaining the distinction between Evolution as a scientific theory and Evolutionism as a popular Myth it becomes possible for one to be a full-blooded theistic evolutionist with both a robust belief in God and a robust belief in evolution. The distinction frees Christians to accept evolutionary science without knuckling under to reductionistic Scientism. Thus, in the very essay where Lewis most acerbically attacks Evolutionism, “The Funeral of a Great Myth,” Lewis also clearly allows for a form of theistic evolution. Lewis writes:

I am not in the least denying that organisms on this planet may have ‘evolved.’ But if we are to be guided by the analogy of Nature as we know her, it would be reasonable to suppose that this evolutionary process was the second half of a long pattern—that the crude beginnings of life on this planet have themselves been ‘dropped’ there by a full and perfect life.¹⁵

As Lewis makes clear in another piece, “Two Lectures,” the “full and perfect life” by which “this evolutionary process” was “dropped” exists outside of Nature, which is to say, exists outside of the purview of the natural sciences. “Is it not…reasonable to look outside Nature for the real Originator of the natural order?” he asks.¹⁶

Lewis, however, was no Deist. He clearly did not believe that the “crude beginnings of life” were simply “dropped” by God so that the “evolutionary process” would do what it would. Lewis seems to have thought that God at least superintended the evolution of humankind, particularly humanity’s cognitive capacities, in a rather hands-on manner:

For long centuries God perfected the animal form which was to become the vehicle of humanity and the image of Himself. He gave it hands whose thumb could be applied to each of the fingers, and jaws and teeth and throat capable of articulation, and a brain sufficiently complex to execute all the material motions whereby rational thought is incarnated. The creature may have existed for ages in this state before it became man: it may even have been clever enough to make things which a modern archaeologist would accept as proof of its humanity. But it was only an animal because all its physical and psychical processes were directed to purely material and natural ends. Then, in the fullness of time, God caused to descend upon this organism, both on its psychology and physiology, a new kind of consciousness which could say “I” and “me,” which could look upon itself as an object, which knew God, which could make judgments of truth, beauty, and goodness, and which was so far above time that it could perceive time flowing past.¹⁷

Whether this picture of hands-on divine guidance is friendlier towards present day Intelligent Design theory or towards theistic evolution, a la BioLogos, will be a matter for debate. Lewis does not draw the distinctions that are customary in contemporary debates surrounding evolution—macro- versus micro-evolution, Evolution qua mere common descent versus Evolution qua wholly unguided, random process, and so on—making it difficult to say with certainty what he would say if he were here today. It seems likely, however, that Lewis would not have expected the natural sciences to be able to detect God’s supernatural guidance of man’s evolutionary path any more than he expected the modern archaeologist to be able detect the moment when our ancestors crossed the threshold from beast to man, and that likelihood might count as a strike against the ID movement’s claim on Lewis. In any case, Lewis plainly outlines a view that is quite compatible with the standard evolutionary picture of common descent and that hardly amounts to Scientistic reductionism. In short, Lewis made it quite clear in his writings that he believed that there is no real conflict between mere evolution and mere Christianity.

Surprised by Jack

Whatever Lewis may have believed in private, as a spokesperson for the faith, Lewis consistently allowed that mere Christianity was compatible with mere evolutionary science, and he even took the trouble to articulate his understanding of the Fall in such a way as to harmonize it with his belief in human evolution. While some recent writers have attempted to wield Lewis as weapon in intra-Evangelical debates around Evolution, to wield a thinker is, as Martin Buber says, to treat that thinker as an ‘It’ rather than as a ‘Thou,’ to treat him as an object to be used rather than as person with the right and capacity to defy our expectations.¹⁸ We evangelicals have become so accustomed to inserting quotable quotes from Lewis’s corpus into our sermons, books, power-point presentations, Facebook walls, and Twitter feeds that we drowsily pass over the surprising elements of his thought—the elements not easily reconciled with our clean-cut theological shibboleths—without even noticing. This is an intellectual habit ripe to be broken, and it is high time we allowed the real Jack to shatter the cultural icon—indeed, the mirror—we have made out of him. At this watershed moment in the history of the Church, when so much seems to threaten to upend the faith once delivered—whether scientific or archaeological discoveries, cultural trends, or newfangled philosophies—there is doubtless much that the greatest modern exponent of mere Christianity can teach us to help us navigate these troubled times. But it is only by opening ourselves to being surprised by Jack that we will be capable of actually learning something from him.

It’s true that physics sounds scary to many people, and it can indeed be a difficult topic to learn. Yet I’ve always loved physics (my degrees are in physics rather than astronomy), because of the way that mathematical equations can describe and predict so much of what we see in the world around us. One reason I got into astrophysics is because the universe contains so many bizarre situations that we can’t reproduce on earth, like ultracold, or extremely high density, or extremely high magnetic fields. It’s a fun challenge to figure out which physical process will be the most important when the situation is so dissimilar to everyday experience. But if the word “physics” makes you shrink in distaste or fear, don’t worry. For the rest of this article, we’ll focus on a more friendly topic: astronomy.

In the last decade or two, our knowledge of the universe has grown dramatically as many new telescopes and spacecraft have come online. In this essay, I’ve selected some of my favorite recent astronomy photographs to share with you. As a professional astronomer and a Christian, I feel God has called me to share these wonders with the Church. Many times, these new discoveries are presented without any mention of God, and sometimes in a context of overt atheism. I want to share these things with you in a Christian context, with God as their creator.

The Milky Way

Have you ever seen the Milky Way? If you live in a rural area, you may have seen it many times. If not, it may have been a dramatic surprise when you first saw it while camping or traveling. On a clear night out in the country, the sky is strewn with brilliant stars—many more stars than you can see under city lights.The faintest stars form a creamy, smoky band from horizon to horizon. Our galaxy contains billions of stars, and thousands of those stars are visible to the naked eye. The stars appear in a band across the sky because we are viewing our galaxy edge-on, like looking at the edge of a dinner plate.

When David looked up at the night sky over Israel thousands of years ago, he may have seen the Milky Way, or a comet, or simply the brilliance of the full moon. Whatever the sky looked like that night, it inspired him to sing:

The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they reveal knowledge. They have no speech, they use no words; no sound is heard from them. Yet their voice goes out into all the earth, their words to the ends of the world. (Ps. 19:1-4a)

The heavens are displaying the glory of God for all people to hear, proclaiming their message to people of every language, tribe, and nation. Just about anyone who looks up at the night sky feels a sense of wonder. Yet as Christians, we feel more than a vague sense of awe; we know the Creator of the heavens personally, as our own loving Father.

The heavens declare more than God’s glory. The universe is God’s revelation of himself to us, and teaches us about his character. As the Belgic Confession says about “The Means by Which We Know God,”

We know him by two means: First, by the creation, preservation, and government of the universe, since that universe is before our eyes like a beautiful book in which all creatures, great and small, are as letters to make us ponder the invisible things of God: his eternal power and his divinity, as the apostle Paul says in Romans 1:20. Second, he makes himself known to us more openly by his holy and divine Word, as much as we need in this life, for his glory and for the salvation of his own. (Article 2)

The natural world teaches us about God’s glory, power, divinity, faithfulness, extravagance, immensity, love, and other attributes. God’s special revelation in scripture is our primary place to learn of God’s character (Ps. 19 goes on to talk about special revelation in vs. 7), but the natural world can bring the message to our senses in a powerful way beyond mere words on a page. The Holy Spirit can use the natural world to get the message past our hardened or weary hearts. Nature illustrates these attributes in ways that enlarge our imaginations to appreciate afresh the glory of God.

The Sun

The Solar Dynamics Observatory was launched into space in 2010, the latest of several spacecraft to photograph the sun in detail. In Figure 2, the upper photo shows the face of the sun with a sprinkling of sunspots. The sun is powered by nuclear fusion reactions deep in its core which heat the hydrogen and helium gas till it glows. A sunspot is a place on the sun’s surface where the gasses are a bit cooler than the surrounding area, so that it glows less brightly and appears dark.

The lower photo in Figure 2 was taken the same day, but in X-ray light. X-rays are invisible to our eyes, but you have experienced them at the dentist’s office. There, the X-rays are produced by a machine, travel through the mouth, and are detected by film to reveal an image of your teeth. In this image, X-rays are produced by the sun, travel to the Solar Dynamics Observatory, and are detected by a camera to show an image of the sun. In X-rays, the sunspots are the brightest part of the image, not the faintest. If you look at the sunspot on the left edge, you can see bands of particles rising out of the sunspot in a looping path above the sun’s surface and falling back down on it. As the particles follow lines of magnetic field, they emit X-rays. The loops you see are not small—they are about the size of planet Earth! Because of modern spacecraft, telescopes, and cameras, we can see so much more in the heavens than what is visible to the naked eye. Thus, we are seeing more of what the heavens have to declare about God. In Psalm 19, David goes on to describe the sun:

In the heavens God has pitched a tent for the sun. It is like a bridegroom coming out of his chamber, like a champion rejoicing to run his course. It rises at one end of the heavens and makes its circuit to the other; nothing is deprived of its warmth. (vs. 4b-6)

If David had lived today, maybe he would have written about other properties of the sun, like the power of God as seen in nuclear reactions and looping magnetic fields. As it is, he makes two important points. One is the universal warmth of the sun, by which God provides for all life on earth. The other is the faithful path of the sun, day after day, unchanging year after year. In the book of Jeremiah, God promises his people that he will not break his covenant with them, any more than he would break his covenant with day and night and the fixed laws of heaven and earth (33:19-26). The sun is a persistent reminder, woven into our lives, of God’s faithfulness to his promises.

As Christians and geologists, we frequently encounter people with stories of storm tossed and shipwrecked faith that started when they began to wrestle with apparent conflicts between science and the Bible. The stories have a common thread. The Bible, they were told, clearly teaches the earth was created a few thousand years ago with life forms fashioned more or less as we find them today. Because the earth is very young, the incredibly complex sequence of rock, sediment, and fossils found on our planet must have been deposited in a very short period of time. Noah’s Flood, as the only plausible causal agent, was obviously a global and violent event. Theories of an ancient earth and adaptation of life forms, they were further informed, have been constructed on flimsy evidence created by atheistic scientists searching for ways to expunge God from modern culture. But as these sojourners began to explore and understand the actual evidence for an ancient earth, they found themselves increasingly convinced of its legitimacy, and thereby increasingly questioning the veracity of their faith – many to the point of relegating Christ to just another wishful myth.

It is our conviction that these stories of strained or lost faith derive not from an inherent unwillingness to trust the Bible, but rather from misguided teaching on the message of Scripture. Those insisting the earth is young are not simply putting their faith in God’s Word, they are putting their faith in their own particular interpretation of that Word. As such, an entirely unnecessary stumbling block to faith is created, where faith in Christ first requires rejection of sound science.

As we have prayed and studied this subject, we have felt God’s call to speak out against this misplaced stumbling block. We are sensitive, however, to the fact that when scientists speak on issues of faith, there is a natural suspicion that science will be regarded as the ultimate arbiter of truth, and Scripture will have to yield whenever conflict arises. It is thus important for us to state here that both of us ascribe to the authority and inspiration of Scripture, the reality and necessity of Christ’s death and resurrection, the existence of genuine miraculous events, and the truthfulness of the Biblical historical narratives. In our understanding, science will never trump Scripture, but by virtue of science being a study of God’s natural creation, it may occasionally assist in our understanding of God’s written Word. Where this has occurred historically and has been accepted by the Church, the invariable result has been the abandonment of an interpretation of some secondary importance, without any change in our understanding of the intended central message.

This phenomenon is illustrated well by the 17th century clash between Galileo’s claims that the earth revolves around the sun, and the multiple passages in Scripture that appear to clearly present a static earth as the physical center of God’s natural creation. The Bible tells us repeatedly that the earth is fixed upon its foundations (Ps 93:1, 104:5) and the sun rises and sets (Eccl 1:5, Ps 19:6). Within the context of the historical narratives (which we are not accustomed to interpreting in any figurative manner) we read statements about “the sun rising over the land” (Gen 19:23), and a miraculous event during a famous battle where “the sun stopped in the middle of the sky and delayed going down a full day” (Josh 10:13). Likewise in the Levitical law, we find commands to complete the Passover sacrifice “when the sun goes down” (Deut 16:6).

God’s people had interpreted these verses for thousands of years to be authoritative statements about both spiritual and physical realms, and 17th century believers understandably struggled with allowing science to alter traditional interpretations. If God says the sun rises and the sun sets, how could it be otherwise?

Fast forward a few centuries, and we are now somehow quite content to have allowed science to alter our thinking on these verses, without abandoning notions of inerrancy or inspiration. The reason is simply because it was eventually recognized that the primary message of these verses was never on the nature of nature, but on the nature of man and his experience with his environment and his God. Solomon and Joshua accurately recorded their experience from an earthly perspective (sun rising and setting), and David praised God for holding the earth fixedly in His hand (Ps 93:1, 104:5), without requiring a meaning of fixity in space. The central message of these verses was apparent to readers before and after Galileo. Only a secondary interpretation, likely never intended by the writers, was cast off after scientific advances.

So what is the issue regarding Noah’s Flood? The modern debate centers around two questions. Was it truly global in extent, and can the Flood account for the earth’s complex geologic record? To address the first, it is worth being reminded of the Apostle Paul’s letter to the church in Rome where he makes a statement that “your faith is being proclaimed throughout the whole world” (Rom 1:8). Entire people groups existed at this time in China, Australia, and North and South America who knew nothing of the church in Rome. Though using wording that literally means the entire world population, Paul is clearly referring to the world known to him and his readers at the time.¹ Paul speaks truthfully from his experience. Allowing for the possibility that Noah’s Flood encompassed all of known humanity without necessarily covering the entire planet is thus consistent with how other passages in Scripture are interpreted by Christians who believe the Bible is authoritative and trustworthy.

Our primary interest in this blog series is the second question, the widely promulgated notion that the Flood can account for the earth’s complex geology, and that all genuine Christians should accept this viewpoint.

Notes

1. Many Biblical scholars define a literal interpretation as one that takes into account the literary genre, figures of speech, context, and author/audience perspective in deriving the intended meaning. By this definition, poetry and allegory are literally interpreted as figurative. In this blog and in our article, our use of literal conforms to its more common definition where a literal interpretation is one that adheres to the precise definition of words without figurative meaning and without requiring additional context to understand.

“Theistic evolution” has been discussed by that name since at least 1877, and one of the first to do so was the great Canadian geologist John W. Dawson, in his book, The Origin of the World, According to Revelation and Science (1877). In the midst of a lengthy discussion of the animals created on the fifth day of creation, he says:

The long time employed in the introduction of the lower animals, the use of the terms “make,” and “form,” instead of “create,” and the expression “let the waters bring forth,” may well be understood as countenancing some form of mediate creation, or of “creation by law,” or “theistic evolution,” as it has been termed; but they give no countenance to the idea either of the spontaneous evolution of living beings under the influence of merely physical causes and without creative intervention, or of the transmutation [evolution] of one kind of animal into another. (p. 225)

As the final part of this sentence implies, Dawson was (ironically) a staunch opponent of both human evolution and the common ancestry of other animals; in short, by no reasonable definition was he a theistic evolutionist, even though he thought that a great deal of change had taken place naturally, “within certain limits” that he associated with the created “kinds” spoken of in Genesis. Indeed, references to “theistic evolution” are probably no less common among opponents of the view (including William Jennings Bryan in the 1920s) than among proponents, but I won’t attempt to enumerate further examples.

In recent years, however, some proponents of TE have endorsed alternative labels for their position(s). The most prominent example is Francis Collins, the geneticist who started BioLogos. Collins uses the term “BioLogos” itself as the label for his overall position, which fits well within my TE category. The evangelical theologian Denis Lamoureux, one of the most qualified of all writers on this topic (he has earned doctorates in both theology and biology), strongly prefers the term, “Evolutionary Creation” (EC), precisely because he thinks the noun “creation” ought to have more emphasis than the adjective “evolutionary,” something that the term “theistic evolution” does not accomplish. I recommend his book of that title to anyone who wants an authoritative analysis of both biblical and scientific aspects of the origins controversy. The main ideas are clearly presented in his web lectures. Another highly qualified proponent of TE, George Murphy, also has reservations about the term, but he recognizes its wide recognition and agrees with the idea itself, that “Evolution is God’s way of creating”. I will have more to say about Murphy, a very important voice, in a subsequent post.

Despite these quite reasonable objections to the term, I continue to use the “TE” term, partly because it has historical continuity and I’m an historian, and partly because it’s easily recognized. If anyone wants to object, however, they won’t get objections from me, unless their own reasons aren’t reasonable. My only request: define your terms as clearly as I’ve defined mine.

Because the term is broad and a bit hazy, more should be said about it. When we talk about “Intelligent Design” next month, I’ll tell you that it’s a “big tent” (something proponents of that view also say), insofar as it glosses over the biblical and theological issues that have usually separated Christians into various “camps” (such as the various positions we are now studying) when it comes to origins. TE is also a “big tent,” in that adherents differ strongly amongst themselves on theological and biblical issues. Unlike ID, however, theology is openly discussed—and competing theologies of God, nature, and humanity are openly advocated, not left implicit. We’ll say more about this next time. This column presents one type of TE, a type favored by many evangelical scientists and scholars. For example, the people I will discuss all accept (as far as I can tell) the Incarnation and Resurrection—that is, they are Trinitarian Christians who believe that Jesus was fully divine (and fully human) and that the disciples went to the right tomb, only to find it empty, before encountering the risen Christ in diverse places. They also believe in creation ex nihilo, the classical view (illustrated at the start of this column) that God brought the universe into existence out of nothing. There are other types of TE, some of which are not (in my opinion) sufficiently biblical, or even sufficiently Christian, to be part of this series. Please keep that in mind as we proceed: don’t tar all TEs with the same brush—something that happens all too often elsewhere. Let knowledge, not ignorance, be our guide.

Core Tenets or Assumptions of Theistic Evolution

(1) The Bible is NOT a reliable source of scientific knowledge about the origin of the earth and the universe, including living things—because it was never intended to teach us about science.

This reflects not only modern scientific knowledge, but also (more importantly) modern biblical scholarship. Peter Enns and some other evangelical scholars have recently stressed this point, initiating a firestorm in the evangelical academic community that, so far, has confirmed my view that evangelicals in general are just not ready to deal with this, even though it is consistent with the classical notion of accommodation. My own comments about the magnitude of the problem, written before the firestorm started, can be found here.

(2) The Bible IS a reliable source of knowledge about God and spiritual things.

Remember the quip that Galileo attributed to Cesare, Cardinal Baronio, “The intention of the Holy Ghost is to teach us how one goes to heaven, not how heaven goes.” (We discussed this earlier in the series). Evolution was not an issue in Galileo’s day, but this platitude is frequently quoted by advocates of TE—and often without proper attribution to Baronio. Commonality obviously lies in the attitude, not the topic. Many critics of TE are willing to adopt Galileo’s approach when it comes to the Solar System, but not when it comes to evolution: they are anxious to keep Galileo out of the garden of Eden.

Portrait of Cesare, Cardinal Baronio,
attributed to Caravaggio (1602-3) (Source)

(3) Scientific evidence is irrelevant to the Bible—it is simply not a science book.

See above. This needs to be stated separately, since some believers look to science for “proof” of the Bible, just as some unbelievers look to science for “disproof.” Proponents of TE stress that science and the Bible aren’t like apples and oranges; rather, they are more like apples and rocks: you can hold one in each hand without tension, but they have very little in common. We wouldn’t look for God in the phone book, or in an automobile repair manual. Don’t look for science in the Bible. In principle, scientific theories neither support nor threaten the Bible.

(4) The creation story in Genesis 1 is a confession of faith in the true creator, intended to refute pantheism and polytheism, not to tell us how God actually created the world.

This is meant to echo what we said about the Framework View. It is not necessarily true that all TEs accept the Framework View or something like it, but many do. Most would probably say that the Bible is not contradicted by any specific scientific theory of biological diversity—unless that theory oversteps its philosophical boundaries and functions as a kind of religion, what Conrad Hyers called “dinosaur religion.”

(5) The Bible tells us THAT God created, not how God created

Again, this sounds like the Framework View—or, at least, it should. Belief in God the creator is consistent with science, and even supported by some aspects of science; but, it is not a substitute for scientific explanations.

An Assignment: It’s Your Turn to Read and Write

Astronomer Owen Gingerich has written an eloquent little TE book, God’s Universe. A number of quotations have been compiled here. My review for First Things identifies some of the key theological and philosophical issues related to TE. Please follow these links, study what you find, and offer comments below. If anyone has actually read the book itself, your views would be particularly valuable to include.

Looking Ahead

In our next column in two weeks, we continue our discussion of Theistic Evolution, focusing on some crucial theological aspects of TE. In the meantime, please do the “assignment” and get back to us.

No Football Coaches

When I explain this position to students, I like to start with a little puzzle. Many years ago, after attending an academic conference in a major city, I was driving through the rural countryside some distance away, en route to an historic house that wasn’t well marked. As I got closer to where I thought I might start seeing some signs directing me to the house, I noticed a fair-sized hotel, restaurant, and bar off to one side of the road. What really caught my attention was a sign, prominently displayed at the start of the driveway, warning off a certain clientele: NO FOOTBALL COACHES, it said. Unfortunately I’d forgotten my camera, but this is pretty much what I saw.

When I show it in class, I ask the students to guess what this was all about: why such a sign outside of such a place? The stories they come up with are pretty good. My favorite involves two neighboring high schools, arch rivals, with the football coach at one having an affair with the wife of his opposite number, resulting in fist-fights in that bar every fall, when friends of one man or the other would go at each other in the bar, which was on the highway connecting the two school districts. After a few students have tried their luck to no avail, someone asks, where did this take place? Was it maybe in England, where football means soccer and coach means bus? Give that student an A, I say. It was England, on a highway running between York and Manchester. Now, who can fill in the blanks? Almost right away, a student will explain that soccer fans in England can be pretty rambunctious, and that a busload of them might not make the best impression on the rest of the clientele at a respectable country inn and pub. Thus, the manager would rather not have their business.

The take-away message, of course, is that there is always a context in which the meaning of a text is embedded. Unless you know something about the time and place in which a text is composed, you aren’t going understand what it actually says. The same is true for any part of the Bible, including the opening verses of Genesis. That’s the bottom line for the Framework View: if you don’t know anything about literature and culture in the Ancient Near East, you won’t understand what Genesis is really saying.

Core Tenets or Assumptions of the Framework View

(1) The “days” in Genesis have nothing to do with historical time; they are literary devices, employed by God in order to communicate the story of the creation in terms that we can understand.

This sounds like an example of the principle of accommodation, and it should. The activities of the six days of creation are arranged into a “framework” of two triads (days 1-3 and days 4-6), with parallel types of activities in each triad.

Thus, light is created on the first “day,” and on the fourth “day” God makes the Sun and Moon, the two great lights in the firmament that produce light and “rule over” the day and the night. The air and sea appear on the second “day,” and on the fifth “day” God fills them with birds and fish, etc. In other words, the order of events seems to be more logical than chronological. The key element is the fourth day: as we noted in our discussion of Concordism, the Sun was not made until the fourth day, yet it was expressly given the task of producing the day and the night and we’ve had “evening and morning” since the first day. What’s going on here? How can this be taken “literally”? Advocates of the Framework view see a solution in the parallel triads.

Another way to see this focuses on the second verse in the Bible, which reads (in the American Standard Version, a translation that follows the Hebrew closely), “And the earth was waste and void; and darkness was upon the face of the deep: and the Spirit of God moved upon the face of the waters.” God is confronted by darkness, a watery abyss, and a formless earth—each of these features posing a problem for God, who deals with them in the subsequent six “days.” First, on “days” 1 to 3, God prepares the heavens and the Earth to be a home for the great creatures to come, by separating light from darkness, separating waters above the firmament from waters below the firmament, and causing the dry land to “appear” and to “put forth” vegetation. Then, on “days” 4 to 6, God makes the creatures and puts them in the places God has prepared—the Sun and Moon in the “firmament of heaven (day 4), birds in the air and fish in the seas (day 5), and finally “the beasts of the earth” and “man” on the land (day 6).

We emphasize that the Framework View is simply about the Bible, not about science. The Earth and the universe can be as “young” or “old” as anyone wishes to claim, because the literary form of early Genesis leaves this an open question. The “days” were probably meant to be understood “literally” as ordinary days, but only in the context of a literary form that was not meant to be understood literally, when taken as a whole.

What about the seventh “day”? Because it lacks a “morning” and an “evening” in the text (have you ever noticed this?), some authors interpret the seventh “day” as a prophetic reference to God’s own eternal rest, which has not yet begun and which we will share with God in the eschatological future. An OEC book I discussed in my column on Concordism, Robert Newman’s Genesis One and the Origin of the Earth (1977), advocates this interpretation (see pp. 65-66), and so do some advocates of the Framework View.

(2) When seen against the cultural and literary context of the Ancient Near East (ANE), it is clear that Genesis was written to combat the polytheism and pantheism of other creation stories. It was not written to provide a scientifically accurate account of the creation.

This is why the Sun and Moon are not even named on the fourth day: they were worshipped as divine beings by many people in the ANE, and the Hebrew author(s) of Genesis intentionally omit their names as an act of defiance against worshippers of those two false gods. (Remember: for the ancient Egyptians, the Sun was the chief god.) Furthermore, the stars are mentioned simply as an afterthought, at the end of verse 16: “And God made the two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.” This was done deliberately, as a way of belittling the Babylonians and others who worshipped them. Indeed, the whole creation account stands in the face of polytheism, by affirming that the one true, invisible God has actually created all visible things, including the heavenly bodies. Nothing we see is divine: this is the essence of monotheism, stated bluntly and boldly.

(3) It is not possible to find a close match between what is proclaimed in Genesis—that God is the creator—and the details of natural history. We should not approach this text with inappropriate expectations.

For many readers, the crucial question awaits: according to the Framework View, is Genesis 1-3 historical in any meaningful sense? Here there is a division of the house, with authors falling into either of these two camps:

(1) Genesis 1-3 is an historical narrative (though not strictly chronological), not a creation myth. As Lee Irons and Meredith Kline emphasize in The G3N3S1S Debate, “The framework interpretation does not teach that creation was a nonhistorical event” (p. 220). The universe was actually created, Adam and Eve were the first humans, and the Fall was a real historical event. Some OECs like this approach, which can be seen as a looser type of Concordism than the day-age theory; Bernard Ramm’s “moderate concordism” might be understood as fitting into this category, even though he did not discuss the Framework View per se.

(2) Genesis 1-3 is not an historical narrative; it resembles some other, older ANE creation stories. Conrad Hyers advances this view in his book, The Meaning of Creation: Genesis and Modern Science ; see below. Some aspects of the story reflect this: the days, the progression from chaos to order, and the creation of humans from mud or clay. These are common to other ANE stories, and they are present in Genesis because that’s what hearers in the ANE expected such stories to include. Other aspects of Genesis, however, are profoundly unlike other ANE stories: the transcendence of God and the de-deification of nature. These constitute the crucial, timeless, substantive message that God has revealed to us. Theistic evolutionists tend to like this non-historical approach, which is not usually seen as a kind of Concordism.

Historical Comments

The Framework View is modern, but its attitude toward the Genesis “days” is similar to that held by Augustine. As I explained in an earlier column, he taught that God created all things at once and told us about it in the pattern of six days, in order that we could understand it. The days themselves, however, were “unknowable” and not meant as a “literal” description of the passage of time.

In the 19th century, the German scholar J. H. Kurtz put forth an interpretation that Ramm called the “pictorial day” view, which he considered to be a type of “Moderate Concordism,” the overall position that Ramm himself favored. Kurtz described the creation story as “prophetico-historical tableaux, [in] which are represented before the eye of the mind, scenes from the creative activity of God, each one of which represents some grand division of the great drama, some prominent phase of the development” (The Bible and Astronomy, 1861 Philadelphia edition, p. 110). His Scottish contemporary Hugh Miller, one of the most prolific and influential evangelical writers of his day, endorsed Kurtz’ interpretation, holding that “the form and nature of the revelation” in Genesis was “conveyed by a succession of sublime visions” (The Testimony of the Rocks, 1857 Boston edition, p. 180).

The Framework View itself, with the “days” arranged in parallel triads, was first proposed in 1924 by the Dutch scholar Arie Noordzij and made more widely known by another Dutch scholar, N. H. Ridderbos. His book—Is There a Conflict Between Genesis 1 and Natural Science?—was translated into English in 1957. Subsequently, Kline and the French theologian Henri Blocher have been its most prominent supporters.

An Assignment: It’s Your Turn to Read and Write

I’ve done most of the heavy lifting in this series, but now it’s your turn. As a way of getting into all three of the views we’ve studied thus far (not simply the Framework View), I’d like everyone to read an article by Conrad Hyers, “Dinosaur Religion: On Interpreting and Misinterpreting the Creation Texts,” Journal of the American Scientific Affiliation 36 (September 1984): 142-48. The questions below are intended as helpful suggestions; feel free to discuss other matters as well!

1. What does Hyers mean by “dinosaur religion”?

2. What is Hyers’ most basic objection to “creation science,” the YEC view?

3. What does Hyers believe to be the true message of Genesis One?

4. Overall, do you agree with what Hyers says? Why or why not? Whether or not you agree, do you have any critical comments?

NOTE: Hyers wrote a sequel, “The Narrative Form of Genesis 1: Cosmogonic, Yes; Scientific, No,” Journal of the American Scientific Affiliation 36 (December 1984): 208-15, in which he employs an interpretive scheme highly similar to the Framework View, although that term is not used. I encourage you to read this also, but our discussion will focus on the first article.

Looking Ahead

In our next column on August 14, we begin a lengthy discussion of Theistic Evolution. Although that is the view advocated (under an alternative name) by BioLogos, I will approach it no differently. After explaining its central tenets, we’ll examine them critically and outline its history. Between now and then, I’m keen to see your responses to the assigned reading. If you gotten this far, you’re more than just a casual reader. Tell us what you think of Hyers’ ideas.

In his book The Greatest Show on Earth (2009) on the first page of the second chapter, Dawkins raises the interesting question: “Why did it take so long for a Darwin to arrive on the scene?” After suggesting possible answers he approvingly quotes the late Ernest Mayr's suspicion as the most insightful answer to this question. According to Dawkins, Mayr’s suspicion is: “The culprit was the ancient philosophical doctrine of---to give it its modern name—essentialism. The discovery of evolution was held back by the dead hand of Plato [Dawkins' language].” Later in his book, Dawkins states boldly that evolution is anti-essentialist, a point Mayr made in other places. One can find the same argument, if not the same language, in the writings of Edward O. Wilson where the idea of nature trumps any idea of something existing above experience. Clearly, I am not the first one to consider this argument. I think, however, that further discussion regarding the implications of essentialism for evolutionary models remains important especially for theists in particular and humanity in general. At the heart of this discussion is the matter of ontology, the nature of being. While evolution speaks to the development of what is, it necessarily carries with it very strong ontological implications, implications that affect views on the nature of being. If the idea of essence has no currency in the discussion of reality, then the thing itself is all there is and, hence, quickly becomes the object complete in itself.

It seems that essentialism (I use this term with Christian emphasis), if true, would seriously challenge any form of evolution where different species evolve through common descent. The point that Mayr and others have made turns on the idea that essentialism provided the philosophical foundation for the idea of fixity of species from at least the time of Plato. If right, that would make evolution, in the sense of producing new species, suspicious if not impossible. Furthermore, it seems that essentialism cannot be easily dismissed simply because it is associated with Plato. One must consider the philosophical/theological legitimacy of essentialism based on the merits of its own claims within the discussion of the nature of reality. With that said, if Mayr and others are right about essentialism, then the question to be taken up is whether essentialism has any ground upon which to stand, especially within Christian theology.

Generally speaking, essentialism teaches there is more to reality of the thing than what is presented to the senses which, is to say there is more to reality than the biological dimension (we might say DNA). It is the material that provides a means of expression of the essence. A member belonging to a natural kind is so because of its essence and all members belonging to this natural kind must have this essence or it does not belong. In this way, natural kinds are distinct from others by virtue of their essence. While essence determines what natural kind to which a thing belongs, there are also non-essential or accidental properties. These help to distinguish one member from another within a natural kind, but these are not determinative for the natural kind itself as they are subject to change while essential properties are not. That is, what makes a cow a cow is the essence belonging to being a cow. Without that, the cow could not be a cow. In other words the idea of essence is what gives stability to natural kinds. If essentialism is true this would, as Dawkins points out, seriously challenge the idea of common ancestry.

Applied to human beings, the essential attributes of humanness are predicated of beings called human beings which distinguishes them from non-human beings –this is not an arbitrary naming. While human beings (a natural kind) share universally the same essence of humanness, they do differ in non-essential properties (short, tall, thin, fat, and so forth). So while the members differ in many non-essential ways, they belong to the same natural kind by their shared essential attributes of humanness.

If what has been called an essence (Plato referred to these as Forms and Augustine as Ideas in the mind of God or eternal reason) explains natural kinds, it is easy to see how this would logically lead to the idea of fixity of species (which may be very broad allowing for a wide range of adaptations and variations within natural kinds which allows for a very rich biological diversity). The suggestion here is that it is time to rethink the matter of essentialism in this discussion. Of course there must be some reason to think that essentialism has merit on its own terms.

The fact that a being is determined by its essence finds support in understanding who Jesus is. Consider what makes Jesus the God-Man. As argued by the early Church Councils, it was His nature (in Greek, OUISA). He had the nature of both---the essence of God and the essence of man. It was not that He had all the outward appearance and DNA function of a man that made him a man---it was more than that. He was a man, precisely because He possessed the nature (essence of a man) and He was God as He had the nature (essence of God). This at least supports the idea that a being is what it is, not by virtue of developmental issues, but because of its essence.

In thinking about essence, one might consider the matter of transubstantiation. One may discount transubstantiation on theological grounds, but it does say something interesting to the discussion of essentialism. It assumes that the bread is of one essence and the body is of another essence. In order for the wine to become blood (a different essence) it would take a miracle as one essence does not give way to a different essence in the process of nature. The idea of transubstantiation is discussed in Aristotelian categories; in this case substantive cause is what Aristotle meant by the whatness of a thing–that is, what makes it what it is. Additionally, Genesis 1:20 notes that living creatures were created according to their own kind (the whatness of the thing) supporting the idea of natural kinds, which is consistent with the idea of fixity of species.

Tomorrow in part 2, Dr. Little makes the case that modern science has unjustifiably marginalized essentialism because it does not fit within a purely physical understanding of reality.

Introduction

Astronomers and geologists have determined that the universe and Earth are billions of years old. This conclusion is not based on just one measurement or one calculation, but on many types of evidence. Here we will describe just two types of evidence for an old Earth and two types of evidence for an old universe; more types can be found under Further Reading. These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years. As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.

Age of the Earth from seasonal rings and layers

If you’ve ever seen a horizontal slice of a tree trunk, you’ve seen how a tree forms a new growth ring each year. In years of drought, the tree grows less quickly so the ring is narrower; in good growing seasons the ring is thicker. A tree’s age can be found by simply counting its rings. By comparing the pattern of thick and thin rings to weather records, scientists can verify that the method is accurate. This method can even be used on dead trees that fell in a forest long ago. For example, the last 200 rings in the dead tree might match up with 200 rings early in the life of the living tree, so the two trees together can count back many years. In this way, multiple trees can be used to build a master chronology for a forested region. European oak trees have been used to build a 12,000-year chronology.¹

The annual ice layers in glaciers provide a similar method that goes back much further in history. Each year, snowfall varies throughout the seasons and an annual layer is formed. Like the tree rings, this method can be verified by comparison to historical records for weather, as well as to records of volcanic eruptions around the globe that left thin dust layers on the glaciers. Scientists have drilled ice cores deep into glaciers and found ice that is 123,000 years old in Greenland² and 740,000 years old in Antarctica.³ These annual layers go back much farther than the 10,000 years advocated by the young earth creationists. The Earth must be at least 740,000 years old.

Age of the Earth and solar system from radiometric dating

In your high school science classroom, you may have seen a large poster of the periodic table hanging on the wall. The periodic table shows the types of atoms that make up the world around us. An element in the periodic table can come in different flavors called isotopes. Some isotopes are unstable, and over time these isotopes “decay” into isotopes of other elements. For example, Potassium-40 is unstable and decays into Argon-40. As time passes, a rock will have more and more Argon-40 and less and less Potassium-40. Radiometric dating is possible because this decay occurs at a known rate, called the “half-life” of the radioactive element. The half-life is the time that it takes for half the radioactive sample to change from one element into the other.

Some isotopes have short half-lives of minutes or years, but Potassium-40 has a half-life of 1.3 billion years. Radiometric dating requires that one understand the initial ratio of the two elements in a given sample by some means. In this case, Argon-40 is a gas that easily bubbles out and escapes when it is produced in molten rock. Once the rock hardens, however, all the Argon-40 is trapped in the sample, giving us an accurate record of how much Potassium-40 has decayed since that time. So, if we find a rock with equal parts Potassium-40 and Argon-40, we know that half the Potassium-40 has decayed into Argon-40, and that the rock hardened 1.3 billion years ago.⁴

It’s hard to find rocks on the surface of the Earth that have not been altered over time. Most old rocks have been eroded by wind and water or submerged by continental plates. The oldest reliably dated rock formation is in Greenland, where several different isotopes were used to find an age of 3.6 billion years.⁵ Scientists also recently dated zircon grains (which resist erosion) in Western Australia to 4.4 billion years old.⁶ To find older rocks that haven’t been eroded, we need to look beyond Earth. Meteorites are rocks from the solar system that have fallen to Earth recently and haven’t suffered much erosion. Their pristine interiors give an age that dates back to their formation at the beginning of the solar system. Nearly all meteorites have the same radiometric age, 4.56 billion years old.⁷ Thus, the solar system, including the Earth, is about 4,560,000,000 years old.

This is very exciting for elementary particle physicists. But what is the Higgs particle, and what is its meaning? At a press conference on July 4, 2012, and with 99.99994% confidence (5 sigma), CERN announced the discovery of a particle consistent with that of a Higgs boson (a.k.a. “the God particle”). This is very exciting for elementary particle physicists. It is also getting the attention of press and general public. But what is the Higgs particle, and what is its meaning?

It has been widely reported that the moniker “God particle” was not its originator’s first choice. Still, Leon Lederman, director emeritus of Fermilab and Nobel laureate for neutrino research, did accept the nickname “God particle” because the particle is “so central to the state of physics today, so crucial to our final understanding of the structure of matter, yet so elusive.” “God particle” was quickly accepted by the press and general public because it seemed an appropriate title for a particle theorized to give mass to all elementary matter particles and the force carrying W and Z bosons. Serving this mass-giving function since near the beginning of the universe, a Higgs field (more fundamental than the actual Higgs boson ) must necessarily exist everywhere in the universe and be unchanging. With an omnipresent and immutable field, analogies between the Higgs boson and God naturally developed within the press and the public—“God particle” became deeply rooted. Relatedly, the Higgs boson become an excellent source for theological analogies. (See for example this article.)

Nevertheless, as physicists seek to emphasize, neither the Higgs boson particle nor its field have religious properties. Thus, elementary particle physicists are not fond of the “God particle” appellation. In the opinion of Oliver Buchmueller, of CERN’s CMS group, calling the Higgs boson the “God particle is completely inappropriate. It’s not doing justice to the Higgs and what we think its role in the universe is. It has nothing to do with God“. As Pippa Wells, another CERN scientist expressed, “Calling [it] the God particle … confuses people about what we are trying to do at CERN”. (Source: Reuters)

One alternate name for the Higgs particle that is used within the physics community is the “BEH” particle. “BEH” stands for Brout–Englert–Higgs, three of the six authors of 1964 papers that first proposed a mechanism for giving mass to elementary particles. In addition to Peter Higgs, the five other authors are Robert Brout and Francois Englert, and Tom Kibble, C.R. Hagen, and Gerald Guralnik. The process for giving mass to particles is thus sometimes referred to not just as the Higgs mechanism, but as the Brout–Englert–Higgs–Hagen–Guralnik–Kibble (BEHHGK) mechanism. (Saying all six names a couple of times makes it obvious why we most often only call it the Higgs.)



But issues of naming aside, what is the Higgs and why is it so elusive? According to the Standard Model, the particles that compose matter (the quarks and leptons) are in a category called spin-1/2 particles. The force carrying particles (the photon, the W's, the Z, and the gluons) are spin-1 particles. What the physicists above proposed was the existence of a type of spinless, or spin-0 particle. Not only does the Higgs boson form its own class of particles, it also gives mass to itself and to all the other particles that have mass: to all of the leptons and quarks, and to the W's and Z bosons, but not photons or gluons. This set of relationships is shown in the image below, indicated by the lines connecting the Higgs to these other particles. There are no lines directly connecting the Higgs boson to photons and gluons because the Higgs boson does not interact with these force carrying particles and, thus, photons and gluons remain massless.



But the story of the Higgs particle actually begins with the associated Higgs field, an invisible field (something like a generalization of an electric field) that has a non-zero, constant value everywhere throughout the universe. This Higgs field continuously interacts with all matter particles and the W and Z force carrying particles. Matter and massive force particles are slowed down as they move through the Higgs field, just as are balls rolling through thick mud. The Higgs field is sometimes described as a “cosmic molasses”. Different particles interact with the Higgs field to varying degrees—those interacting more, are slowed down more, those interacting less are slowed down less. Slowing down more equates to acquiring more mass. If not for the Higgs field, all particles would be massless, zipping through the universe at the speed of light. The universe would be without structure—no galaxies, no plants, no life. Without the Higgs field, not even atoms could have formed.

It should be noted, however, that the majority of the mass of protons and neutrons (and thus of atomic mass) does not come from interaction with the Higgs field. Each proton and neutron is composed of three quarks, which do receive their mass from their interaction with the Higgs field. However, the masses of protons and neutrons are much greater than the sum of their constituent quarks and are a result of the additional mass contribution from the binding energies of the “trapped” quarks.

It was theoretically possible for elementary particles to have mass without needing to acquire it through interaction with a Higgs-like field. However, as the standard model of elementary particles developed in the 1950’s and 1960’s, elementary particle theorists realized that if particles had their own innate mass, rather than acquiring it, many beautiful symmetries of particle interaction equations would be broken. To keep the beauty and symmetry in the theory was the essential reason the BEHHGK mechanism was developed, which immediately led to the prediction of Higgs bosons.

When there is enough external energy in a given volume, the Higgs field also produces Higgs bosons. But the Higgs bosons are very unstable and quickly decay. This is the process that enabled the discovery of the Higgs boson at CERN. At CERN, protons are accelerated to high energies via electric fields and directed in circular paths via magnetic fields. The protons then collide and release large amounts of energy. When sufficient energy is released in a collision, the Higgs field can use this energy to produce Higgs bosons. The Higgs bosons quickly decay leaving evidence of their existence through particular combinations of leftover particles that they have decayed into. Among those predicted by the mathematics of the Standard model are the muons and electrons identified by the CERN experimenters. The image at the top shows the identities and paths of particles produced in one of the CERN proton-proton collisions whose results fit with what would be expected from the decay of a Higgs boson.



For a proton-proton collision at the CERN LHC, the above diagrams show both the dominant modes for creation of a Higgs with a mass around 125 GeV, and the two dominant decay channels (modes). The creation mechanism (shown schematically in the left half of each diagram above) involves virtual gluons, the carriers of the strong nuclear force (represented by squiggly purple lines) from the protons. The gluons fuse into a virtual top quark loop (medium blue triangle), which then emits a Higgs boson (squiggly yellow line). The top quark couples more strongly to the Higgs than any of the five other quarks, so the top quark contributes the dominant loop.

The Higgs boson then dominantly decays into either (i) 2 gamma ray photons (the squiggly green lines) via another intermediate virtual top quark loop or a virtual W gauge particle loop (dark blue triangle), or (ii) two Z0 gauge particles (squiggly dark blue lines), which each then decay into a lepton (specifically an electron or a muon)/anti-lepton pair (light blue lines).

The likely discovery of the Higgs boson, and its implied existence of the associated Higgs field, is an amazing success for CERN. Past research and experience at Fermilab and by elementary particle physicists throughout the world also contributed to the discovery. The Higgs boson was the remaining particle in the Standard Model of Particle Physics to be found. With it, the Standard Model is in some sense complete. (Nevertheless, many questions about the Standard Model still remain—many inspired once again by beauty and symmetry. In particular, several numeric values associated with particle masses and interactions could only be experimentally measured, as with the Higgs, and not predicted from the Standard Model.)

With the apparent success of these experiments and seeming confirmation that the physical universe is, indeed, reflected by the complex and beautiful mathematics of the Standard Model, the international physics community is eager to keep delving deeper into the structure of creation. In addition to trying to verify that the 125 GeV particle is, indeed, the Higgs spinless particle and not some more exotic, new particle, CERN physicists are simultaneously seeking to discover an entire new class of particles, resulting from a theorized symmetry called supersymmetry. Discovery of the associated particles, if they exist, will likely take a few more years. For these discoveries we can only wait in anticipation.

Is there actually any theological or religious significance in Higgs physics at all? The image above describes an "event" (proton-proton collision) recorded in 2012 with the CMS detector at CERN's Large Hadron Collider. According to CERN, "the event shows characteristics expected from the decay of the SM Higgs boson to a pair of Z bosons, one of which subsequently decays to a pair of electrons (green lines and green towers) and the other Z decays to a pair of muons (red lines). The event could also be due to known standard model background processes. ATLAS Experiment © 2012 CERN

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?"

Today we have a chance to witness a special moment in history as Venus transits across the disk of the Sun for people across the world to see. This rare astronomical occurrence may have been witnessed by Montezuma in 1520, was first predicted by Johannes Kepler in 1631, launched Captain James Cook’s expedition around the world in 1768, helped us determine the Earth's distance from the Sun in the 1882, and will not occur again until 2117.

The astronomy community is particularly interested in this event because exoplanets throughout the Milky Way galaxy regularly transit their parent stars in just the same way. This local example will allow astronomers to test and refine techniques used to determine the composition of these exoplanets' atmospheres, providing insight into whether these distant planets could possibly harbor life.

As Venus begins to cross in front of the disk of the Sun, Venus's atmosphere will refract the Sun's light, illuminating the backlit portion of the planet's atmosphere. Telescopes on the ground and in orbit will be trained on this thin arc of atmosphere lit up by the Sun. Astronomers will use spectrometers to break the light up into its constituent colors, from which they can determine the chemical composition of our over-heated sister planet's atmosphere. Once perfected, this same technique can be used to examine the atmospheres of planets far beyond our own solar system, offering us one of our best clues as to the habitability of these distant worlds.

Not only is this process of discovery exciting for natural science, but it has profound theological ramifications as well. Surely a God capable of orchestrating both the majestic swirls of a spiral galaxy and the intricate language of DNA could bring forth life where and when He chooses, but only now are we on the verge of being able to answer the age-old question: “Did God confine His creative life-giving actions to our own planet, or does His abundant fertility extent far beyond our limited experience?”

In 1882, William Harkness, the Director of the U.S. Naval Observatory, was one of two astronomers to determine from the transit of Venus the distance from Earth to the Sun. Just as previous viewers could never have imagined calibrating the scale of the solar system from such an event, Harkness could not predict its importance in 2004 and 2012 (the most recent Venus transits). As we look to the future, we can hardly imagine what new frontiers the next Venus transit of 2117 will find us exploring.

"We are now on the eve of the second transit of a pair, after which there will be no other till the twenty-first century of our era has dawned upon the earth, and the June flowers are blooming in 2004. . . . What will be the state of science when the next transit season arrives God only knows. Not even our children's children will live to take part in the astronomy of that day. As for ourselves, we have to do with the present ..." ~William Harkness, the Director of the U.S. Naval Observatory, quoted in 1882 (source: NASA.gov)




The image above shows Venus on the eastern limb of the Sun during the 2004 transit. As described in Tucker's essay, the faint ring around the planet comes from the scattering of light through its atmosphere, which allows some sunlight to show around the edge of the otherwise dark planetary disk. The faint glow on the disk is an effect of the TRACE telescope through which the image was captured. For more on the historical significance of the transits of Venus (including the voyage of Captain James Cook), see this article from NASA, which also includes links to several live webcasts of today's transit.
