So, I’ve decided to try a slightly different approach for the next while—one that has these sorts of folks in mind. From time to time, you can still expect those more in-depth, technical articles, or perhaps a discussion of some new research that makes the popular press, or even an analysis of some new argument from the IDM or RTB. These will be breaks from the new routine, however. For the most part, we’re going to stick to the basics, much like you would if you took an introductory evolution course at a university. Don’t worry, though: this course doesn’t have any prerequisites! All that’s needed is a willingness to learn.

What you can expect

The goal of this course is straightforward: to provide evangelical Christians with a step-by-step introduction to the science of evolutionary biology.  This will provide benefits beyond just the joy of learning more about God’s wonderful creation. An understanding of the basic science of evolution is of great benefit for reflecting on its theological implications, since this reflection can then be done from a scientifically-informed perspective. From time to time we might comment briefly on some issues of theological interest (and suggest resources for those looking to explore those issues further), but for the most part, we’re going to focus on the science. For folks interested in the interaction between science and Christianity, I heartily recommend Ted Davis’ recent series as a fabulous introduction to the topic.

You can also expect a slow, patient pace. Since this course is intended for folks with little or no background in biology, we’re going to take our time to make sure no one gets left behind. This might be frustrating to folks who already know a fair bit about evolution. Hopefully even more knowledgeable readers will learn some new and interesting details along the way—but the goal will primarily be to help folks who are less well versed in evolution increase their understanding.

You can also expect a survey of many different areas that have some bearing on evolution. We’ll examine geology, paleontology, biogeography, genetics, and a host of other topics in order to provide a “big picture” overview. This broad-brush approach means that any given individual post will not necessarily be “convincing” to folks who have doubts about evolution. Think about assembling a large jigsaw puzzle: placing any individual piece, on its own, doesn’t convincingly demonstrate what the overall picture will show. This course will be like that. Each topic we cover will put a few pieces in place here and there, slowly building towards the final overall picture.

Since evolution is an active science, this process will also highlight where there are “missing pieces” that are still being sought by scientists. All of this is well and good, since the purpose of this course is not so much to convince anyone of the validity of evolutionary theory, but rather to inform readers about the nature and scope of evolution as a scientific theory in the present day. My goal is to provide readers with a basic understanding of what evolution is and how it works. Given that as the primary goal, if one finds the scope of the evidence ultimately convincing (or not) is somewhat beside the point. The intent here is to provide readers with information they can use to make their own, informed decision.

How you can help

First and foremost, you can help by spreading the word about this series to folks you think would be interested in learning more about evolution in a non-threatening environment. Secondly, you can help me by asking questions in the comments. One of the challenges of being a specialist is having the ability to put oneself in the shoes of someone just starting out. What might seem obvious to me may not seem obvious to you, and I hope you’ll feel that no question is too basic or too simplistic. If you’re wondering about something, it’s almost guaranteed that other folks are, too! So, please don’t be shy. I’ll do my best to answer questions in the comments, though I hope that some of our more skilled commenters will (respectfully!) help out here, as well. Finally, you can help by letting me know what broader areas of evolution you find confusing. I have my own ideas about what areas of evolution are commonly misunderstood, but I’d love to hear from readers about what areas they find difficult to understand. I’ll use this input to shape the topics I will cover as we go forward.

Getting started

In the next post in this course, we’ll dive into the course content by introducing two key areas: how scientific theories work in general, and how evolution in particular works as the current organizing theory of modern biology. 

Antibody fine-tuning

At this moment, millions of B cells are patrolling my spleen and lymph nodes, each sporting a different antibody on its surface. If a foreign molecule from the cold virus happens to stick to an antibody on a particular B cell, the cell can get “activated.”

Pathogens are like cockroaches. If you see one roach, you can bet there are many more lurking under cupboards and between walls. Just as one shoe won’t kill them all, one B cell can’t make enough antibodies to deal with an infection. Activation causes the B cell to reproduce, creating more and more B cells that can produce the same kind of antibody.

As is typical during cell division, most of the DNA in dividing B cells is copied with extremely high accuracy. But in the gene segments coding for the variable region of the antibody, mutations accumulate about a million times more often than normal. Why would this be? Isn’t the point of B cell replication to make more identical antibodies?

Almost. It turns out that these frequent random mutations contribute to optimize the antibody. A shopping story helps to illustrate. I was recently at the mall and found a fabulous pair of shoes on sale. Sadly they were out of my size, but it was such a good sale that I decided to buy the half-size down, figuring the shoes might stretch out a little and grow more comfortable with time. Bad idea! That great bargain turned out to be pretty expensive when I got blisters and never wore the shoes again. Clearly this was not an optimized choice.

Just because you can get your foot into a shoe does not mean it fits. Likewise, just because an antibody binds to an antigen does not mean the two are perfectly complementary. Descendents of the activated B cell have a mechanism to induce mutations so each one can make a slightly different version of the antibody. If one of the resulting B cells makes a better-fitting antibody than its kin, it will have a selective advantage and proliferate. The other cells will not become activated as often and will end up dying by apoptosis, a kind of cellular suicide. This mechanism of mutation and selection, called affinity maturation, produces a highly specific, strong interaction between the antigen and the antibody.

Antibody production and evolution both involve mutation and selection

I believe God is sovereign over all of creation, but I don’t imagine he is presently curing my cold by directly controlling the specific gene rearrangements and optimizing mutations in each of the millions of B cells in my body. Could he do so? Of course! But if that were the case, why bother making billions of antibodies in the first place? The evidence suggests that God has chosen to work through a random process, one which involves the routine creation and destruction of millions of cells that never get used. This is the ordinary means by which God maintains our health. The miracles of healing recorded in the Bible are miraculous precisely because they don’t occur by this normal, natural process.

In my last post, I stated that the generation of antibody diversity is an example in which God uses a “blind” system to sustain and preserve life. I then suggested a link to evolution by asking, “If God uses natural mechanisms that work over short time scales (less than a week) to evolve life-giving solutions to disease, could he also use a similarly elegant approach to create life over long periods of time?”

Some may argue that a small-scale process like antibody production isn’t comparable to the processes of mutation and natural selection that are supposed to have caused macro-evolution. Intelligent Design proponent Michael Behe, for example, accepts that all creatures (including humans) have a common ancestor, but he believes random mutations are not powerful enough to have brought about the diversity of life we see today. He argues that there is an “edge” of evolution: mutation can bring about drug resistance and other small-scale adaptations, but beyond a certain point it can’t really produce anything new.

Clearly, antibody production creates something new: the random recombining of whole gene segments generates highly specific, never-before-seen protein functionality within just a few days. The body can respond to any foreign entity, simply by sorting through billions of ready-made possibilities. Furthermore, a pretty-good solution can be made even better by generating many variations on a theme and sorting through these for the optimal antibody.

Evolution works by the same kinds of mechanisms, except the mutations occur in germ cells (which give rise to egg and sperm) rather than in B cells, and the sorting (selection) process occurs at the population level rather than the cellular level.

Though often neutral or destructive, mutations sometimes create new functionality

Most people are familiar with point mutations, in which a single DNA “letter,” or base, gets changed. However, mutations come in several other varieties. Short sequences of DNA can be inserted or deleted at random. Chunks of DNA can get cut out and inserted in the opposite direction. Individual genes or even whole chromosomes can get lost or duplicated. In rare cases, the entire genome can get duplicated!

The effect of a mutation principally depends on where it occurs, not on the size of the DNA segment affected. A large deletion occurring within a long stretch between two genes may do nothing at all. On the other hand, a single point mutation within a critical gene may cause a devastating disease. There is also a third possibility though: new functionality may emerge as a result of a mutation.

Let’s consider the protein hemoglobin, for example, which binds oxygen and transports it throughout the body in the blood. Hemoglobin is made from two pairs each of two amino acid chains, called α and β (blue and red in the figure at right). The corresponding genes that code for α and β have similar sequences to each other, and are believed to have arisen when an ancestral globin gene (still present in marine worms, insects, and some fish) duplicated and slowly changed over time. While the ancestral form can bind oxygen just fine, the four chains of hemoglobin cooperate to do so even better.

Both the α and β genes have undergone further duplications followed by smaller mutations. As expected, many of the resulting genes have become irreparably damaged by mutations, but they continue to exist in the genome as inert DNA “fossils.” Others, however, remain active and now perform specialized functions. For instance, one set of β genes binds more tightly to oxygen than the others; it becomes active only during development to ensure that the fetus gets enough oxygen from the mother’s bloodstream. A few months after birth, fetal hemoglobin turns off and the adult form turns on.

To summarize, mutations come in many forms (e.g. rearrangements, insertions, deletions, duplications) and can lead to good, bad, or neutral effects within an individual. B cells depend on random mutations to produce novel antibodies. A few are productive, but the vast majority of B cells die unused. Yet the entire process works for our good! In the same way, mutations in germ cells can lead to no effect, disease, or new and better solutions, as we saw in the hemoglobin example. These are the ordinary (but masterful!) means by which God creates and sustains life.

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.

Conversations about science and faith can be like that. People hold clearly discordant points of view, and it would be dishonest to ignore the conflict. Yet some voices emphasize the dissonance without any note of harmony to put it in context. Too often, science and faith becomes a hostile battle of worldviews, sounding angry, dissonant chords even among fellow Christians. But civil, gracious dialogue is possible. On the BioLogos Forum, we invite authors from a range of positions, including some that don't agree with all our beliefs, but we strive to set these dialogues in a context of respect and civility. When authors are fellow Christians, we don’t shy away from disagreements, but remember the broader context of our unity as fellow believers, the harmony that binds us together.

My own story is more harmonious than dissonant. My interest in music was paralleled by my interest in math and science and my involvement in church. My family and teachers encouraged my interests in science, and I remember how fun it was to play math games with my dad and brother. And every week we were in church: twice on Sunday, plus Wednesday night club, youth group activities, and Bible quizzing. While my church accepted the young earth position, they didn’t emphasize it, and I was never told that a particular science view was essential to being a Christian. When I encountered the evidence for the age of the universe and the evolution of life, I also found Christian authors who showed me how this scientific evidence could fit with Christian beliefs.

But others have experienced more dissonance. Nearly four years ago, Dr. Francis Collins launched this website with the story of a young university student in the midst of a profound personal crisis, what Dr. Collins called “a wrenching crisis of worldviews shaking her deepest foundations.” Without a context of harmony, too many people – young and old – feel they have to choose between two incompatible positions, either Christian faith or the findings of science. BioLogos exists to show another way. We hold fast to the authority of the Bible and the core beliefs of Christianity, and at the same time, accept the rigorous conclusions of mainstream science.

It is with these chords of dissonance and resolution in mind that I come to this opportunity to lead BioLogos. I have long sensed God’s calling to serve the church as part of this dialogue. Some of you know of me from a book I wrote in 2007 with my husband Loren, called Origins. I’ve been speaking and writing on science and faith for many years, but I did this around the edges of my primary career of teaching and research in astronomy. While I thoroughly enjoy teaching students and doing research, over the last year I have recognized God’s hand in leading me to shift my fulltime work to the science and faith dialogue. Now I’m looking forward to using and developing my gifts in service of BioLogos.

Joining me as a new member of the leadership team is Dr. Jeff Schloss, who will serve as our Senior Scholar. Many of you are already familiar with his work, and know he brings not only a strong track record of scholarship in evolution and philosophy, but tremendous skill in communicating to lay audiences. Jeff and I share a deep commitment to the unity of the body of Christ and a desire to remove barriers for people to come to Christ. I am delighted to have him on board.

Jeff and I inherit a strong and vibrant organization from our outgoing President, Dr. Darrel Falk. Darrel brought his deep love and concern for the church, along with his considerable creativity and hard work, to this effort. We plan to continue and build on the excellent programs he established.

One of the pleasures of my first few weeks on the job has been getting to know the BioLogos staff. Kathryn, Lisa, Stephen, Mike, Laura J, and LeAnne each bring key skills to the organization, as well as energy and a passion for the mission of BioLogos. The team keeps BioLogos functioning behind the scenes, from finances to computer programming to event planning. Two team members, Mark Sprinkle and Tom Burnett, have decided to move on to other opportunities after a year of dedicated service to BioLogos. As web editors, Mark and Tom revamped the blog, making it a forum for rich scholarly dialogue and vibrant testimonies, and drawing in new authors to write on a great mix of topics. They also organized the archived material, so that the best of BioLogos is readily accessible. We wish them well in their new endeavors. Joining the BioLogos team is Emily Ruppel as Interim Web Editor. You may know Emily from her work to develop and edit the e-zine God & Nature for the American Scientific Affiliation; she will join us part time at BioLogos while she continues to work with ASA.

We believe God has great things in store for BioLogos. We will continue to focus on connecting with scholars, pastors, teachers, and lay people, but in the months ahead, we will also be sharpening our vision and engaging afresh in strategic planning. We’ll be considering new audiences, new programs, and new priorities. I invite your comments below on directions you’d like to see BioLogos take.

In just a few years, this organization has impacted the lives of thousands of Christians and brought an important voice to discussions taking place within the church. Thanks to the strong support from The John Templeton Foundation and many other generous donors, the vision of Francis Collins is thriving. BioLogos is on the cusp of enormous opportunities and huge potential. While transitions are times of risk and vulnerability, they are also times of great opportunity. My prayer is that God will give us wisdom and guidance to be good stewards of this opportunity. May God continue to use BioLogos to bring harmony to a conversation that has emphasized dissonance for far too long.

As a Board, our transition process has focused on selecting leaders who embrace Christ as Savior and science as the pursuit of understanding God’s work in His creation. Both Haarsma and Schloss have demonstrated their commitment to these two fundamental principals in their scholarship as well as in their lives.

President Deborah Haarsma, Ph.D.

Dr. Deborah Haarsma is Professor of Physics & Astronomy at Calvin College in Grand Rapids, Michigan. In recent years she has become well known to the BioLogos community as a regular contributor and consultant to our blog and Questions section, as well as an active member of the Board of Advisors. Dr. Haarsma’s deep commitment to her faith and enthusiasm for science have made her a popular public speaker in churches as well as private Christian schools and universities.

A graduate of Bethel University in St. Paul, Minnesota, Dr. Haarsma earned her Ph.D. in astrophysics from the Massachusetts Institute of Technology. An experienced research scientist, her work on galaxy clusters and gravitational lenses has been published in The Astrophysical Journal and The Astronomical Journal.

Dr. Haarsma grew up in a Christian home and an evangelical church. Since her college days, she has felt God’s call to be an ambassador: to share Christ’s love in the academic world of science, and to share the wonders of God’s creation with the church. Her first book, Origins: Christian Perspectives on Creation, Evolution, and Intelligent Design, was coauthored with husband, Dr. Loren Haarsma, a biophysicist. Origins respectfully explores the range of views held by Christians on creation, evolution, and human origins and is used in many Christian schools and colleges to navigate these complex issues. Haarsma’s latest book, Delight in Creation: Scientists Share Their Work with the Church, co-edited with Rev. Scott Hoezee, invites Christians to explore the discoveries of science through essays by Christian biologists, astronomers, mathematicians, and other scientists.

A gifted musician, Dr. Haarsma is active in her local church, playing piano for the choir and worship services. In a recent article, Dr. Haarsma shared how her own worship of God as creator has been intensified by her scholarship in science, saying “I have learned to praise God for the glory of the systems he has put in place. Rather than picturing God making each mountain individually, I praise him for carefully designing a whole system of continental plates that slowly but powerfully raised up the snowy heights of the Himalayas. Rather than picturing God creating each individual flower, I praise him for designing the system of evolution to create an extravagant variety of flowers of all shapes, colors, and scents. A scientific explanation does not replace God; rather, it is our best human description of the natural mechanisms God uses. This understanding can actually increase our awe and worship, giving us a glimpse into how God works.”

Dr. Haarsma is grateful for this opportunity to lead BioLogos in its work to draw pastors, teachers, scholars, and students into the expanding conversation about evolution and its compatibility with biblical faith.

Deb Haarsma is not only a scientist but an active participant in the church and a devoted follower of Christ. I could not be more excited about her leadership from my perspective as a pastor. She deeply cares for the faith community that she is trying to equip with the knowledge of God's creation, so that we will all be able to glorify Him more completely.

Senior Scholar Jeffrey Schloss Ph.D.

Dr. Jeffrey Schloss is Distinguished Professor and T.B. Walker Chair of Biology at Westmont College in Santa Barbara, California where he directs the Center for Faith, Ethics and Life Sciences. He is well known to the BioLogos community through his writings on evolution and faith for our blog, as well as his informative presentations at numerous BioLogos events.

Dr. Schloss is well respected in the academic community for his extensive work on evolutionary theory, ethics, and the Christian faith. He is a frequently invited speaker at scholarly conferences, has co-edited several academic volumes, and publishes in venues such as Religion, Brain & Behavior, Behavioral & Brain Sciences, and Journal of Theology & Science. His many awards and honors include Oxford University’s Plumer Fellowship, the Crosson Fellowship in Philosophy of Religion at Notre Dame, and the Witherspoon Fellowship in Theology and Natural Sciences at Princeton’s Center of Theological Inquiry.

After a life-changing encounter with the gospel as a college drop-out, Schloss returned to school and graduated from Wheaton College. He went on to do post-baccalaureate fieldwork at the University of Virginia and the University of Michigan biological stations, completing his Ph.D. in Ecology & Evolutionary Biology at Washington University in St. Louis, Missouri.

Since meeting Christ, Dr. Schloss’s life passion has been seeking to understand – and engaging others in their quest to understand – life through the revelation of scripture, the counsel of the Spirit, and the wisdom of science. Dr. Schloss has worked with Young Life and local high school ministries for many years. He speaks widely on Christian college campuses and at secular universities at Veritas, Intervarsity, and CRU (Campus Crusade) events. And he is grateful for the opportunity to teach and preach at his own and other churches. A mainstay of his life in Christ is a small group of long term friends in the faith, who hold him accountable and with whom he prayerfully considered the call to work with BioLogos.

Dr. Schloss is excited by the opportunity to build bridges of dialogue on the relationship between science and faith, in light of the invitation to “worship the Father in Spirit and in Truth.”

Dr. Schloss will hold a joint appointment with BioLogos and Westmont College.

The future of a great organization depends on the quality of its leaders, and the quality of its leaders is shaped by the courage to form a succession of leaders. BioLogos began with splendid leaders and it is time now to move to the next generation of leaders. I could not support more the appointment of Deborah Haarsma and Jeff Schloss, both able scientists, intelligent teachers, and exceptional communicators of the importance of science for the faith of ordinary Christians.”

The Evolution of BioLogos

It’s been a little more than four years since this project was launched by Dr. Francis Collins and a group of energetic graduate students. At the time, Dr. Collins’ book, The Language of God had resulted in a deluge of emails and letters from Christian students across the globe, inspired by Dr. Collins’ ability to combine his award-winning science with his deeply-experienced Christian faith. Those thought provoking questions combined with Dr. Collins’ desire to offer meaningful answers, provided the inspiration for our website.

Since that time, BioLogos has experienced tremendous growth in the numbers of fully committed followers of Christ who resonate with our efforts and have joined the conversation. Our website now includes over 1200 blog entries and receives nearly 2 thousand “hits” a day. Nearly a million people have visited our website since it’s launch and many of them have returned, for a total of over 2 million visits.

Our annual pastors conference continues to attract some of the most noted authors and leaders of our time. Our summer workshop for Christian teachers is considered a professional high point in the lives of many participants, and we recently awarded 37 grants to scholars and church leaders to advance the dialogue between evolution and Christian faith. We are humbled and grateful as we’ve seen God’s hand at work in all of these blessings.

Throughout this growth, we remain committed to exploring and celebrating the compatibility of evolutionary creation and biblical faith. As always, we are guided by the knowledge that all things are held together in Christ our Savior.

Many have called the 21st century the 'Century of Biology'. A key challenge for the Church in this century is not merely to integrate, but to celebrate, the intricacies and beauty of nature as part of robust Christian faith. The work of the BioLogos Foundation is and will continue to be crucially important in helping the Church to meet this challenge. The addition of Deb Haarsma and Jeff Schloss to an already impressive team is an exciting next step in BioLogos' continuing mission."

During the past year the first results were published from the "Encyclopedia of DNA elements" project ('ENCODE'), revealing that at least 20 percent of the genome, perhaps more, is involved in regulating the expression of its 21,000 protein-encoding genes. The "selfish gene" had its day in the sun, but has now been replaced by the image of a finely tuned genomic system in which each type of gene product cooperates via an intricate networking complex to generate the music of life. The vast array of epigenetic signals whereby genes are switched on or off ensures a steady flow of two-way communication between the genome and its wider environments.

The human as a complex, interactive and highly integrated system might not on the face of it seem a fruitful hunting ground for those who see the genes as pulling the strings of life. Nevertheless, the past year has continued to see a growing love affair between the social sciences and genomics. This is well illustrated by a recent article in Nature entitled: "The anatomy of politics -- from genes to hormone levels, biology may help to shape political behavior." The author writes that "An increasing number of studies suggest that biology can exert a significant influence on political beliefs and behaviors," reporting that "genes could exert a pull on attitudes concerning topics such as abortion, immigration, the death penalty and pacifism." The political scientist John Hibbing is quoted as saying that "...it is difficult to change someone's mind about political issues because their reactions are rooted in their physiology."

Geneticists have highlighted the suspect nature of such claims from a purely scientific perspective. But in our present context it is the way that the genetic results are reported that is most striking. Note the dualist language involved and its assumption of genetic determinism. Genes and physiology are seen as something different from "us" and "our mind," and they seem to be controlling us, so we can't even change our mind. Humans are presented as pawns of their biology, puppets dancing to the tune of their genetic masters.

What has all this to do with the "big idea" concerning human identity that the Imago Dei provides? More, it turns out, than initially meets the eye. The clash of ideas here between theology and science comes not at the level of the science itself, which, in this case, remains ambiguous and disputed, but at the level of the ideological packaging of scientific ideas. To see where the clash comes from, we first need to understand the revolutionary nature of the Imago Dei idea in its original context in the texts of Genesis.

For millennia it was uniquely the pharaoh or the king who was seen as being in the "image of a god" in the polytheistic political systems of ancient Egypt and Mesopotamia. Adad-shum-ussur, a court astrologer and cultic official in the seventh century B.C. royal court of Nineveh, made clear that the Assyrian king Esarhaddon is the very image of Bel (Marduk), the top god of that era:

A (free) man is as the shadow of god, the slave is as the shadow of a (free) man; but the king, he is like unto the (very) image of god.

Richard Middleton provides further examples in his book, The Liberating Image, which describes how the stratified urban society of great cities such as Babylon was structured politically, socially and economically round the king's court and the cultic practices of temple worship of the various polytheistic deities of the city. Social destinies were unchanging because rooted in powerful creation myths. Power was in the hands of the privileged few and true freedom belonged only to the king, for only he was in the image of a powerful god.

Would Hebrew thinkers and writers have been familiar with this idea? Almost certainly, yes, since Israel had significant cultural and economic contact with both Egypt and Mesopotamia over prolonged periods, not least during their periods of exile. So how would the original readers of that wonderful theological essay, Genesis chapter 1, have understood these words?:

Then God said, "Let us make adam [humankind] in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground." So God created adam in his own image, in the image of God he created him; male and female he created them. [Genesis 1:26-27].

In its historical context, the implications were revolutionary: the kingly and priestly male roles previously allocated to the privileged few by a pantheon of gods were now being delegated instead by the one creator God to the whole of humanity, male and female. In a stroke the entire ruling and priestly structure of Mesopotamian society was delegitimized. The Imago Dei was being democratized and it was now humankind who were to be the significant players in the arena of earthly life, the mandate to rule underlying their new responsibilities. Above all, humanity was set free by the one true God to determine their own destiny, no longer under the yoke of all-powerful dictators, nor under the baleful astrological control of the moon and stars.

Yet, ever since, humans have become experts at re-enslaving themselves, refusing the responsibilities that come with free-choice and submitting instead to narratives of fate and destiny. It seems ironic that today it is not the creation myths of ancient Babylon but the ideological interpretations of biology that provide the narratives of fate, in which genes "pull" humans toward certain political views and people cannot change their minds because their convictions are "rooted in their physiology."

"It's in his or her DNA" is a new phrase becoming increasingly embedded in our language, referring to something that cannot apparently be changed. On Sept. 8, 2012, Brad Pitt was quoted by the Daily Mail as saying that "America is a country founded on guns. It's in our DNA. It's very strange but I feel better having a gun." No it's not in our DNA, Mr. Pitt, either literally or metaphorically. People have choices -- they are the prisoners neither of their genetics, nor of their physiology, nor indeed of their environments. Human beings made in the image of God are free to chart their own destiny in a way that preserves human value and dignity. On that we can leave the last word to Abraham Lincoln: "...nothing stamped with the Divine image and likeness was sent into the world to be trodden on, and degraded, and imbruted by its fellows" (Aug. 17, 1858).

Morality, or more strictly our belief in morality, is merely an adaptation put in place to further our reproductive end.

Important scientific theories invite philosophical and theological reflection. Dawkins, Ruse, and Wilson, have described their conclusions. But scientific theories are often compatible with multiple philosophical and religious interpretations. For example, Newton's laws of motion and gravity allow several competing theistic and atheistic interpretations.

To avoid Ruse and Wilson's philosophical conclusion, we need not dispute their scientific hypothesis about how morality evolved. We need only dispute their philosophical extrapolation as to why morality exists. Even if we restrict ourselves to an atheistic worldview, this extrapolation is questionable. Donald MacKay (1965) would call this an example of "the fallacy of nothing but-tery". This is the assertion that a description of something at one level renders other levels of description meaningless. From our everyday experience, we know that a successful description on one level does not invalidate other levels of description. For example. one might assert that a Shakespeare sonnet is "nothing but" ink blots on a page (MacKay 1965). True, one way to describe a sonnet is to precisely specify the page coordinates of every ink blot. This description is valid and complete on its own level; however, one could also analyze the sonnet linguistically, emotionally, socially, historically, and on other levels. If one is programming an inkjet printer, the most important description is in terms of ink blot coordinates. For almost every other purpose in life, however, that is an unimportant level of description. In the same way, a complete evolutionary description of the existence of morality does not necessarily invalidate the truth, utility, or significance of other levels of description of morality.

If we do not restrict ourselves to atheism and instead allow for the existence of a creator, the extrapolation from how morality evolved to why morality exists fails further. Consider an analogy. Suppose an inventor builds a robot which could do a variety of useful things-- mow the lawn, clean the house, grade homework, write book chapters, and so on. One thing this robot can do, given a complete set of spare parts, is build a replica of itself. Whenever the inventor needs another robot, she gives one robot a set of spare parts and has it build a replica of itself. Amongst all the software subroutines within this robot, there is a set of subroutines that govern the robot's self-replication, including the replication of those self-replication subroutines. Would it be correct to say that the purpose of the robot's existence is merely to reproduce those particular self-replication subroutines? Do all of the other software and hardware of the robot--which allow it to mow the lawn, and so on-- merely further the reproductive ends of those self-replication subroutines? At one level, the robot's hardware and software do serve to reproduce those self-replication software routines. At another level of analysis, however, those self-replication software routines serve the robot to produce more copies of itself. At still another level, those self-replication software routines serve the robot's creator. The creator of the robot should get the last world as to which of those levels of description is most important.

In humans, does morality exist to further the reproduction of certain genes, or do those genes exist in order to allow for the production of new human beings who can behave morally? If human beings have a creator, the creator gets the final word on the question of purpose. The mechanism which the creator used to make those genes-- whether de novo or via evolution-- is secondary. The creator's purpose in creating those genes decides the issue.

Kenneth Keathley and I first met in June, 2011, when I was leading BioLogos and he was responsible for academic programs at Southeastern Baptist Theological Seminary. Many Southern Baptist scholars believe the universe is less than ten thousand years old and virtually all are opposed to evolution—the notion of God having created all life forms, including humans, through a process that includes common descent from microbial life. BioLogos, on the other hand, is an organization specifically dedicated to showing that mainstream science—including evolutionary biology—and a conservative biblically-grounded Christian faith are fully compatible. With our respective institutional affiliations, one would have expected Dr. Keathley and I to be at opposite poles in the science and faith dialogue, and on some issues we were. Yet in the brief time we had together that day, we came to see that on the matters that were most fundamental to our Christian faith, we weren’t poles apart at all. Because we were both followers of Jesus who fully respected the Bible as the divinely inspired Word of God, the ties that bound us together were stronger than the forces which seemed to push us apart.

Still, we could not ignore those forces that were pushing us apart: Dr. Keathley had legitimate concerns about theistic evolution¹ and we both believed it important to reflect on those concerns. In response to our conversation, I wrote the following note to him a few days after our initial meeting:

I am very concerned that we (those who are less skeptical about mainstream science) be thinking along with leaders like yourself about the theological issues in a respectful, indeed earnestly prayerful manner. I think we very much need the help of conservative theologians. We cannot rerun the slide towards a watered-down liberal Christianity! I also sensed that you would be willing to listen and explore with us how best to engage mainstream science in a manner different than most evangelicals have done so far.

With those aims of true dialogue in mind, I proposed that Dr. Keathley request a set of articles from his colleagues which would outline their concerns about the evolutionary creation view. The series, which included a set of BioLogos responses to the essays from the Southern Baptist theologians, began in March on 2012 and has continued intermittently throughout the year.

I am grateful to Dr. Keathley for arranging the submission of these papers, and to the authors for taking the time to articulate their concerns. As we have developed our responses, our own thinking has been clarified and this has given us an opportunity to outline our commonalities as well as our differences. I think each of us—Southern Baptist scholars and evolutionary creation scholars alike—would agree that we are nowhere near as far apart as we had thought. Indeed, I think a significant portion of what was perceived as a gulf separating us was due to the fact that we at BioLogos had not yet laid out our positions clearly enough, not least because BioLogos itself has been growing, adapting, and finding our place in the public square. Indeed, we have changed some of our focus as we have carefully weighed the concerns raised by our Southern Baptist colleagues and others to whom we want to be accountable as brothers and sisters in Christ.

Today, along with this overview of the project, we post the last paper of this series. Written in the Fall of 2011 by Dr. Steve Lemke, provost at New Orleans Baptist Theological Seminary, it shows just how far we’ve come in clarifying our positions and addressing key issues other believers have about evolutionary creation. Virtually all of the issues that Dr. Lemke raised at that point have now been addressed in our responses to previous posts in the series. As you read his article, you’ll be able mouse over highlighted phrases to bring up sidebar text showing how we have responded to each given point through the other articles in the series. Indeed, I think Dr. Lemke’s article is a great ending for the series; it re-states clearly both the major concerns and the misconceptions that many evangelical Christians have about evolutionary creation.

This final post in the Southern Baptist Voices Series is also a fitting ending to my term as the as President of The BioLogos Foundation. My goal in leading the organization for these past three and a half years has been to lay the groundwork to help my fellow evangelicals see that the conflict between our faith and mainstream science is not as great as many perceive it to be. In the process, my thinking has been significantly shaped by listening to people who think differently than I do. Some of the people I came to respect and admire the most still believe the universe is less than ten thousand years old. Others believe it is old, but they do not believe that God created life’s diversity through the evolutionary process, and they don’t believe in common descent. Though I think they are wrong about those important facts (even as they think I am wrong about the findings of mainstream science), I have appreciated my interaction with them. After all, laying the groundwork for a more fruitful interaction between science and evangelical Christianity begins with gathering together at the Table to worship, to pray, to study, to think, and to be a manifestation of God’s love together, especially in and through our differences.

We believe that the Southern Baptist Voices project should and will continue, and we’re currently in conversation about the best steps to take to ensure that it does. Moreover there are several other important projects of this sort that have not been quite so visible—at least on the website—and I remain very enthusiastic about them as well. One of my favorite projects has been carried out in conjunction with my colleagues at Point Loma Nazarene University: our annual week-long workshop for fifty Christian school science teachers. Another is our work alongside of our brothers and sisters in Christ at Reasons to Believe. This kind of cooperation—between BioLogos and those who think quite differently about creation than we do—is important for the Church’s witness to our Creator and Savior; the foundation is now in place and we’ll be able to build upon it going forward—laying out our similarities and differences together, rather than building walls between us.

Looking back, leading BioLogos at this very critical junction in the history of the Church has been the greatest privilege of my career. A couple of weeks ago I was with my 96 year old father and we were going through some of his old files. We found a reference to a dream he had in September, 1977, while I was a brand-new Assistant Professor at Syracuse University. At the time, my career as a molecular geneticist was focused on trying to understand how genes worked in engineering the process of development from a fertilized egg. My father dream was that I had made an all-important discovery about the nature of life. Like most dreams, it never came true in the way he expected it might. But a few weeks later in mid-October 1977, I decided to visit a small evangelical church—a move I thought might be my last desperate attempt to find a church for my family and me that would equip me to function as both a scientist and an evangelical Christian: before that day I had all but given up my search for such a community. Yet it was finding that church, not something that happened (or ever could happen) in my lab, that constituted my single most important discovery about the nature of life. Much better than my father’s dream about genes, I discovered there was room for people like me in a Bible-focused church after all.

The Church must not lose its scientists and its many university-educated young people who go on to accept the findings at the core of biology, geology, physical anthropology and astronomy. But we who accept the foundations of these disciplines need the Church to affirm and hold fast to the centrality of Scripture and the truths of the faith, even as the Church, in turn, needs to listen closely to what science has to say about the creation we scientists study so intricately.

I continue to be in regular dialog with people who are somewhat leery about those science textbooks, and I have come to understand the basis of that leeriness. It is not that the science books are wrong, it’s that we scientists have done a somewhat lousy job of sitting down with those who are not scientists and talking about the contents of those books; moreover, it is that we scientists have done too much talking to each other and not enough listening to the legitimate concerns that others raise. We now need to move towards a new reality—a reality which begins with conversation.

That’s what this Southern Baptist series has been about. I know of no better way to end my leadership role in BioLogos than with the final posting of this series. However, even this ending is just the beginning. For all of us, the real work lies up ahead—just around the next bend.

Dr. Lemke’s essay may be found here. Please keep in mind that it was written about fourteen months ago, before the series began. Together with the work of all of the Southern Baptist scholars, this essay shows how important it has been to clarify our positions. Again, as you read the essay, each highlighted section is linked to a “pop-out comment” which will appear in the sidebar as you click or mouse over it. In each case, the comment will show where one of the previous BioLogos responses in this series has addressed the point Dr. Lemke has made. This does not mean that the matter is settled—not by any stretch. It simply means that we’re thinking about the issues he raises and it shows some of our thoughts so far.

Notes

1. Indeed, it is likely the term, “theistic evolution” was part of the problem: evolution is the noun and God’s role in it only an adjective. “Evolutionary creation” is a better term, and the one we prefer.

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

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

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

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

If a cadre of outspoken, strong atheists wrote a litmus test for scientists, that might very well be question #1.

"Scientists, if you're not an atheist, you're not doing science right," PZ Myers -- a well-known blogger, biology professor and atheist -- regularly preaches.

But if this is true, then as many as half of scientists are doing science wrong. A 2009 study from the Pew Research Center polled members of the American Association for the Advancement of Science (AAAS). Fifty-one percent of respondents reported a belief in a higher power. Does this mean that it's too late for science? Has religion already pillaged the minds of researchers worldwide? No, of course it hasn't.

"It seems to me that we as a society have lately been caught in this false dichotomy where it's either God as the guy with the beard on the cloud or nothing at all," neuroscientist David Eagleman told Discovery News.

Staunch atheists often falsely characterize followers of religion as being "all-in" with their beliefs, opining that they ascribe to the whole creationist, woo-y shebang. "Where's your evidence?" atheists mockingly question. "You can't prove that God exists!" they accuse (correctly). Yet, hypocritically, strict atheists are guilty of the exact same crime: belief without evidence.

"We know too little to commit to a position of strict atheism. [But] we know way too much to commit to any particular religious story," Eagleman said.

Just as it's a leap of faith for a religious person to assert that God incontrovertibly exists, it's an equally large leap for a strict atheist to declare, without question, that God does not exist. As Carl Sagan eloquently explained:

An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do now to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.

Absence of evidence is not evidence of absence. As this statement applies to science, so does it apply to religion. History is replete with signs that an all-powerful deity may not exist, but such substantiation is nowhere near tantamount to proof -- especially, as Albert Einstein said, in a universe as incomprehensibly vast as our own:

The human mind, no matter how highly trained, cannot grasp the universe. We are in the position of a little child, entering a huge library whose walls are covered to the ceiling with books in many different tongues. The child knows that someone must have written those books. It does not know who or how. It does not understand the languages in which they are written. The child notes a definite plan in the arrangement of the books, a mysterious order, which it does not comprehend, but only dimly suspects. That, it seems to me, is the attitude of the human mind, even the greatest and most cultured, toward God. We see a universe marvelously arranged, obeying certain laws, but we understand the laws only dimly.

Ultimately, the key is not to be swayed to one extreme or the other -- fundamentalist religion or strict atheism -- but to walk a reasoned middle path. Eagleman believes that path is "possibilianism," the concept of holding multiple beliefs or hypotheses whilst exploring new ideas.

"The goal is to avoid committing to any particular story," Eagleman told Discovery News, "whether that's religious fundamentalism or strict atheism. The goal of possibilianism is to retain the wonder that drives us all into science in the first place and to avoid acting as though we know the answers to things we can't possibly know at the moment."

Strict atheists do the world an incredible service by promoting the scientific method, skepticism, and critical thinking. But they do a disservice by campaigning against religion or touting -- as pure truth -- the non-existence of God, for those actions (especially the latter) are just as unscientific as a blind belief in all aspects of religion.

This summer, a worldwide poll showed that atheism is on the rise and religiosity is on the decline. It is my hope that these "New Atheists" and agnostics won't narrowly focus on denigrating religion, but will instead focus on encouraging open-mindedness and discouraging fundamentalism.

That would surely make the world a more enlightened place.

My valiant helper, a small-sized tiger
Sleeps sweetly on my desk, by the computer,
Unaware that you insult his tribe.

Cats play with a mouse or
with a half-dead mole.
You are wrong, though: it’s not out of cruelty.
They simply like a thing that moves.

For, after all, we know that only consciousness
Can for a moment move into the Other,
Empathize with the pain and panic of a mouse.

And such as cats are, all of Nature is.
Indifferent, alas, to the good and the evil.
Quite a problem for us, I am afraid.

Natural history has its museums,
But why should our children learn about monsters,
An earth of snakes and reptiles for millions of years?

Nature devouring, nature devoured,
Butchery day and night smoking with blood.

And who created it? Was it the good Lord?

Yes, undoubtedly, they are innocent,
Spiders, mantises, sharks, pythons.

We are the only ones who say: cruelty.

Our consciousness and our conscience
Alone in the pale anthill of galaxies
Put their hope in a humane God.

Who cannot but feel and think,

Who is kindred to us by his warmth and movement,

For we are, as he told us, similar to Him.

Yet if it is so, then He takes pity
On every mauled mouse, every wounded bird.
Then the universe for him is like a Crucifixion.

Such is the outcome of your attack on the cat:
A theological, Augustinian grimace,
Which makes difficult our walking on this earth.

–Czeslaw Milosz,¹

The Problem

The poem above communicates in a very poignant and profound way the essence of the theological problem of death, pain, and suffering in the natural world—what has been referred to as “natural evil.” As we will see, it may also point to at least one aspect of a Christian response.

I have become convinced that one of the fundamental issues underlying much of the resistance of many Christians to an ancient, evolving creation is that of the problem of “natural evil.” “Natural evil” is also very often a primary focus of those who reject a personal and compassionate God, as it was for Darwin himself. The issue of theodicy thus seems not only to drive many people of Christian faith away from an acceptance of the conclusions of modern science, but also to drive members of the scientific community away from a serious consideration of the claims of the Christian faith. The topic is important, then not because its solution is central to the validity of the Christian faith, but because it often serves as an unnecessary stumbling block to a productive engagement of both science and faith.

The tension generated by our understanding of God’s character, as revealed in the Bible, and by the reality of the natural world around us has been the focus of much theological and philosophical debate within the Christian church since the first century. This article sets out to examine critically several of the proposed solutions to this problem, viewing them from the perspective of a geologist, paleontologist, and orthodox evangelical Christian.

The theological problem of death and pain emerges from the following propositional statements:

1. Scripture consistently declares the absolute goodness of God and the very goodness of his creation. Furthermore, Scripture declares God’s love and care for creation, and the glory and praise it returns to him.
2. Scripture also confesses a transcendent God who is omnipotent in power, yet immanent in creation as well. God’s creative activity is not described as being confined to some past event at the beginning of time, but as a present and continuing reality. God upholds creation in its being from moment to moment, and is creatively active in its history. This understanding of God’s relationship to creation has been well articulated by Jürgen Moltmann.²
3. In seeming conflict with these confessions of God’s character, we observe death, pain, and suffering as ubiquitous, even integral, aspects of the creation around us.

The apparent conflict between God’s goodness and the presence of pain and suffering is made especially acute when we consider the nonhuman creation.³ How can we accommodate the death and suffering of animals within a theology that declares both God’s omnipotence and goodness? C. S. Lewis forcefully puts the issue before us in his book The Problem of Pain:

The problem of animal suffering is appalling; not because the animals are so numerous ... but because the Christian explanation of human pain cannot be extended to animal pain. So far as we know beasts are incapable either of sin or virtue: therefore they can neither deserve pain nor be improved by it.⁴

Because the issue of animal pain so directly impacts our understanding of the goodness of creation, I will focus particularly on solutions to the problem as posed by Lewis.

How do we then reconcile the goodness of God who is immanent and active in his creation with the death, pain, and suffering we see embedded within it? There seem to be two basic alternative approaches to this dilemma.⁵

1. Natural evil can be attributed to something independent of God and acting against his will. This position threatens to limit God’s power and freedom.
2. Natural evil can be considered a part of God’s good purpose for creation, and either directly willed or permitted by him. Such a view would seem to bring into question God’s goodness and love for his creatures.

The tension between these alternatives—and efforts to avoid their negative theological consequences—surface in many of the proposed solutions to this problem.

In part 2, we start to look at some of the proposed solutions, beginning with the idea that a perfect creation was corrupted by a fall.

This issue is considered by Robert Wennberg in “Animal Suffering and the Problem of Evil,” Christian Scholar’s Review 21 (1991): 120–40. It is obvious to me that, for many animals at least, pain and suffering are a very real conscious experience.

5. As stated by John Hick, in Evil and the God of Love, rev. ed. (New York: HarperCollins Publishers, 1977): “For every position that maintains the perfect goodness of God is bound either to let go the absolute divine power and freedom, or else to hold that evil exists ultimately within God’s good purpose” (pp. 149–50).

Throughout my various conversations with fellow believers, the most-mentioned anxiety over accepting an evolutionary creationist paradigm is the fear of losing the Bible as one’s spiritual anchor and source of authority—the texts that give the global Christian community its doctrinal and philosophical distinctiveness. Growing up in the Baptist tradition and later becoming a member of the Southern Baptist Convention, the inerrancy of “God-breathed”¹ Scripture and its identity as the fount of all truth was paramount in defining my life as a Christian believer. Of course, while some would debate the veracity of such a doctrine as it pertains to this discussion, I believe that neither inerrancy nor authority is at issue when it comes to Genesis’ opening chapter. The real issue is hermeneutics—how we read the authoritative texts.

John Wesley (1703-1791), the eighteenth-century Anglican cleric and theologian who founded the Methodist movement in partnership with his brother Charles, held to a “literal” method of interpretation:

The general rule of interpreting Scripture is this: the literal sense of every text is to be taken, if it be not contrary to some other texts. But in that case, the obscure text is to be interpreted by those which speak more plainly.²

A modern adaptation of Wesley’s hermeneutic states, “If the literal sense makes good sense, seek no other sense lest you come up with nonsense.” But though this is a commonly-used interpretative method in evangelical Christian churches today, I have found that it unnecessarily lends itself to the fear of losing biblical authority. This tendency toward fear is especially acute when the individual doing the interpreting does not have at his or her fingertips the full scope of knowledge required to allow the biblical text to speak for itself—or rather, to allow God to speak through ancient genres with which the interpreter isn’t naturally familiar.

I readily admit that the “literal sense” of Genesis 1—as dictated by our own culture that focuses on material origins and unwittingly holds Genesis 1 hostage to the scientific method—does in fact rule out cosmological and biological evolution as God’s creative methods. But I would also ask the question of whether a “literary sense” of Genesis 1 allows for evolution. To read evolution into Scripture (eisegesis) or out of Scripture (exegesis) would be dishonest, especially considering that the author (or final redactor) of Genesis was not privy to modern scientific discoveries. I would also argue that a “literal” reading of Genesis 1, framed by our own modern paradigm, is unfaithful to the original intent of the author, and that we should take special care to read Genesis 1 “literarily” through the eyes of the ancient Hebrews, understanding what was (and wasn’t) important to them. Dr. Conrad Hyers writes:

This is the interpretive issue, and it cannot be settled by dogmatic assertions, threats about creeping secularism, or attempts to associate views with skepticism . . . . Nor can the issue be settled by marshaling scientific evidence for or against either evolution or six-day creation, since it would first need to be demonstrated that the Genesis accounts intended to offer scientific and historical statements. Otherwise the whole discussion is based on the wrong premises. As such it is scientific creationism itself which compromises the religious meaning of Genesis and is an accommodation to scientific language and method.³

Since Genesis was written in the Hebrew language and most of us can’t read Hebrew, we take for granted the necessity of translating from an ancient language into another in which we are fluent. Yet, we often forget that, because we are separated by at least 2,500 years from the culture that produced Genesis, we also need the culture “translated” for us as well.⁴

Returning to the text

Adopting Wesley’s hermeneutic strongly lends itself to ruling out both old-earth creationism and theistic evolution, but as a firm believer that “all truth is God’s truth,” I felt that I was missing something. Because I believed (and still do) that the six days of creation were six, successive, 24-hour periods (“there was evening and there was morning—the n^th day”), I struggled mightily to understand Genesis 1 in light of what I had been learning about the vast age of the cosmos as determined by the best scientific minds, both secular and Christian.⁵ If the age of the cosmos truly was as old as the scientific establishment has led us to believe, I thought that digging deeper into the culture of the ancient Near East could help me reconcile the two opposing forces of scientific observation and biblical testimony.

It was at this time that I discovered the works of John Walton, Professor of Old Testament at Wheaton College. His commentary on Genesis⁶ and his book on the conceptual world of the Hebrew Scriptures⁷ propelled me toward a realization that the focus of Genesis 1 was much less on the material origin of the cosmos and much more on the cosmos’ purpose as a functional and purposeful dwelling place for God—a cosmic temple, if you will. Furthermore, his reading actually accentuated mankind’s role as representative “image-bearers” of God, as wielders of his authority on Earth. I learned that the symbolism and literary structure of Genesis 1, including the 7-day structure of the creation week, had its roots in an ancient Near Eastern (ANE) cognitive environment that held the concepts of function and purpose to be more important than (but not entirely exclusive of) material origins, the latter of which currently guides our modern, scientific way of thinking. It even reconciled the seemingly contradictory accounts of a weeklong series of creative acts and a 14.6-billion-year-old universe.

With these interpretive tools in hand, I was able to successfully assuage my fear of losing biblical authority insofar as Genesis 1 was concerned, and my openness to evolutionary theory came quite naturally. If the preponderance of scientific evidence adequately explained the existence of all biological organisms, past and present, by evolutionary means, I could accept mainstream evolutionary theory⁸ while maintaining the theological authority of the Bible’s opening chapter. As long as I took pains to bridge the vast cultural gap when attempting to determine the theological message of the text—which God accommodated for the Hebrew culture and chose to express in a culturally bound literary form—I wouldn’t need to fear abandoning the Bible as a source of theological truth and spiritual authority. As long as I aimed to let the Bible to speak for itself, using the best biblical scholarship available to determine who wrote the various books of the Bible, to whom they were written, and when they were written, I could have confidence that the end result would be a more faithful pronouncement of what the Bible is actually telling us, millennia later, through ancient voices.

Of course, things are never that easy when it comes to biblical authority. The functional ontology and temple imagery of Genesis 1, as well as its parallels with other ANE creation myths and temple dedication texts, carry over into the next two chapters of Genesis, which feature the creation of Adam and Eve and the entrance of sin and death into the world of mankind. What was I to do with the historicity of Adam and Eve?

If the Hebrew Scriptures stood alone as a source of spiritual authority in my life as a Christian, it wouldn’t be much of an issue. I could accept a mythological Adam and Eve within the framework of an etiological account⁹ of human origins, but there is this second corpus of literature held sacred by Christians commonly known as the New Testament. As a Christian, I now had an issue with Paul and his clear treatment of Adam as a real person rooted in human history. If that wasn’t enough, I was also confronted by the salvific role of Jesus himself. How could an historical, literal Jesus solve the very real problem of sin that resulted from the rebellious act of a mythical, literary Adam? I’ll address those issues next time, when we look at the second fear many evangelical Christians have about considering evolutionary creation: the fear of losing our Savior.

However, with so much content on the site, older posts—even the best ones—often became lost in the shuffle. So we asked ourselves two questions: How do we give our visitors access to our vast archive of resources, and how do we make sure they are finding the resources that address their most pressing questions?

The answer is our new Resource Finder.

The Resource Finder rests on a foundation of 41 topic tags, covering everything from Genesis to genetics to worship. By selecting any topic, users can find the posts addressing the issues that interest them. Looking for more detail? Users can also narrow their results by choosing an intended audience and format, or by adding more topics to the search.

Here’s an example: Say you’re looking for resources about creation and origins. Just click the “Creation & Origins” tag, and the matching results appear below almost instantly.

You can refine the results by adding a second tag to the search. Let’s add “Genesis”. The results will list all the entries that match both tags first, followed by posts that match either. You can change the list to include only results that match all selected tags by choosing “All” rather than “Any” at the top of the tag list.

Lastly, let’s pick a format and intended audience. How about videos for pastors?

And there you have it! From over 1,300 resources, we’ve found five specific videos, geared towards pastors, that address both Genesis and origins. Want to share the results? Just copy and paste the link from your browser! Even better, by click the orange RSS button in the top left corner of the page, you can create a custom feed for Google Reader (or any other RSS reader) that will let you know whenever a new resource matching those categories goes live on our website!

We’re excited to see what the BioLogos community thinks about the Resource Finder, and even more excited to see how it will impact the ongoing dialogue about science and Christian faith. So have a look and share your thoughts in the comment section below!

There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.

—Hamlet Act 1, Scene 5

We live in a world driven by the gods of economics, technology and science. Particularly in a time of economic austerity, it is tempting to see the arts or humanities as an optional “extra”—a happy by-product of those true engines of society when they are running smoothly. But in this article we will look at how a biblically informed worldview might turn this perspective on its head, and what the humanities might have to tell us about the present contours of the science and faith conversation.

In his iconic 1959 Rede lecture, “The Two Cultures,” CP Snow noted the dysfunctional relationship between science and the humanities, arguing that the situation is principally the result of our educational system in the West. Ken Arnold, from the medicine and arts focused Wellcome Collection in London, believes that the split continues today, but with the further extension that

In emerging countries . . . amongst the middle classes there is a strong pressure to join the ranks of doctors and scientists and engineers because they see that as the place where future economies are growing. . . . In some ways you could almost begin to feel sorry for the arts and the humanities because they seem to be worth less than the sciences.¹

Is Protestant Christianity also peculiarly prone to such thinking? A skepticism of art in religious spaces as a result of iconoclasm and the reformation, combined with a proud history of the protestant work ethic, economic success, and a profound influence on the history of science, might lead Protestants to be more inclined towards the sciences and technology than to the arts. However, there are more corrosive reasons that science has usurped the humanities in our culture than merely educational or theological bias.

In the early 20th century, logical positivists regarded the humanities as expressions merely of our inner states and desires, but having nothing to do with objective reality. Such imperialistic claims to knowledge denied that other knowledge claims referred to any true reality, and were therefore not really forms of knowledge at all. Bertrand Russell writes,

But if there is a world which is not physical, or not in space-time, it may have a structure which we can never hope to express or to know … Perhaps that is why we know so much physics and so little of anything else.²

Christian scientists are of course very sensitive to this, and work hard to explain that science cannot answer questions of ultimate meaning or the existence of God, which are beyond the scope of science. Often, this line of thinking can be narrow in focus, delineating the limits of the science, and naming those assumptions made by science that cannot be justified empirically. Such arguments can be very fruitful within this narrow context, but we should not be led into thinking that our true perception of reality is limited to such analytic and evidential approaches. There are fields of inquiry that science isn’t able to explain (such as metaphysical judgments, ethics, and beauty), and even our confidence in mathematics— upon which so much of science itself is based—rests upon assumptions that cannot be experimentally demonstrated.

The human condition

Mathematics and the sciences do seem to provide tools by which we are able to perceive the external world and its regularities. However, the arts and humanities, too, are a way of understanding reality, and they tell us less about external reality than the internal human condition. The problem is that the ‘human condition’ seems to have been relegated by many to the realm of mere desire and subjective feeling and, therefore, not reality.

The modernist account of science is that, through our reason, we are somehow able to get outside of nature and describe it objectively. The biblical account, though, has human beings as part of the created order, and so embedded in nature—made from the dust of the earth. Given that, human thought life is also part of the natural world, even despite the fact that it is not best described by the sciences.

The works of Shakespeare, for instance, are part of the created order, as are the poems of Wordsworth, the sculptures of Michaelangelo, and the music of Bach, not to mention children’s nursery rhymes, home decoration, and humming tunes whilst waiting for the bus. As C. S. Lewis wrote, "This is not panache, it is our nature." ³

A little reflection on life reveals something very strange going on here. Somehow, the mythic ‘war’ between science and religion has become the dominant battleground for defending the Christian faith, and competing explanations of the material world are used as apologetic weapons. But the reality is that science plays a peripheral role in our experience of life, not least our life as Christians. Of course that is not to deny the enormous impact of science on the material conditions of our lives, or the prevalence of the products of science. Instead, it is to observe that science plays a facilitatatory role, enabling us to carry out the real core business of our lives, which does not revolve around science. Cars, trains and airplanes are modes of transport to take us to work, or to see family, or go on holiday. Social media provide another way of being in relationship with people. Health services are not an end in themselves, but aim to make people well, so that they can get on with their lives. Why then, when life is not about science, does science dominate our way of thinking about life?

In focusing so much energy on opposing positivism are we not being inadvertently drawn into a positivist way of thinking, that science and material explanations of things are, indeed, our basic reality, what is ultimately true?

A biblical model

“We feel,” wrote the philosopher Ludwig Wittgenstein, “that even when all possible scientific questions have been answered, the problems of life remain completely untouched.” ⁴ Likewise, philosopher Susanne Langer questions any philosophy which claims to be able to explain everything:

Philosophers in every age have attempted to give an account of as much experience as they could. Some have indeed pretended that what they could not explain did not exist; but all the great philosophers have allowed for more than they could explain, and have, therefore, signed beforehand, if not dated, the death-warrant of their philosophies.⁵

Fortunately, the Bible preserves us from total positivist oblivion. There are a great many types of literature represented in the Bible, with the notable exception of scientific writing. If we long to be able to express our deepest emotions, we have the psalms; if we are looking for wise advice, we have the proverbs; if philosophical reflection, Ecclesiastes. There is poetry, song, history, biography, but there is no science. In addition, the Bible refers to the use of the visual arts in, for example, the designs of the tabernacle and temple. The Bible does seem to think the arts and humanities are fundamental for human life, but it doesn’t seem to think that what we think the physical world is constructed of matters much at all.

Do we sometimes read the Bible more like a science textbook than a novel or a poem? Most will agree that each type of literature needs to be read in its own way, but lip-service to that idea notwithstanding, recent arguments prove that it is still possible to read a poem with a scientific mentality—looking out for the ‘facts.’ Is that because we have too high a view of science, or because we have too low a view of the humanities? To say something is poetic is not to declare it ultimately untrue, futile and meaningless—it is to say it is more profound and meaningful and true than many other modes of expression.

According to Langer, part of the problem is the priority that has been accorded to discursive language as the only valid way we have of representing reality to each other. She observes that a study of symbolism shows us that this is actually only one way humans use to abstract from reality, and in fact, the situation even with discursive language isn’t as simple as has been made out. She notes that our sensory organs mediate our perceptions of the world and are already on the job— formulating, framing the world to us—before our cognitive apparatus gets to work. It must be so, or we would not be able to evaluate the importance of the vast array of sensory data we receive and reality would appear as a blur.

A linguistic symbol carries a concept we associate with it, which in turn denotes a reality. In language there is a commonly agreed definition for each word we use, thus enabling communication. But each person also has associations unique to him or her which color any particular concept. Though such personal associations with words are present all at once, they can only be expressed and communicated one at a time, because language is also sequential.

A picture also acts symbolically, though in a different way. Even something as ‘realistic’ as a photograph is likewise a representation of reality and not the reality itself. It also carries with it layers of meaning which reflect the subjective intentions of the person who took the photograph, and opens up for interpretations and associations of the person ‘reading’ the picture. A picture, though, is not sequential. All the information comes at once, and individual blotches of color carry no significance on their own, but only as part of the whole.

No amount of words could ever describe a picture in full. The number of blotches of color and their relations to each other are vast in their complexity, and one could never read words quickly enough to carry the meaning a picture brings in an instant, even if it warrants a far longer period of contemplation. Indeed, though we are only speaking here of visual perception, the same is true of our other sensory inputs, too: they all carry knowledge in quite distinct and profound ways, whilst we, in line with the Greeks, have tended to give sight a special place as the most ‘objective’ of our senses.

As we dig down into empirical science and explore the mechanisms by which sights and sounds and textures are transmitted and processed by the brain, we discover that the meaning of the sense-data which we perceive and which we attempt to describe is likewise profoundly limited by the use of words—much less mathematics—and that our science, as such, represents a tiny fraction of reality.

To suggest, then, that science is the only true way of representing reality—as positivism has done—or to exclude the humanities from our world, leaves us without a proper or even adequate means of expressing the significance we attach to even the most mundane day-to-day activities. Science is very good at describing the regularities of the physical world, but the experience of being human is no less part of the real natural world than are the structure of proteins or the movement of planets, and science does not have the appropriate tools to explore our inner worlds.

Nowadays it seems that Christian cultural life has also too-often failed to fully acknowledge other ways of representing reality than materialist science—ironic because this state of affairs is so at odds with the Bible’s model of using the arts and humanities to profoundly explore the human condition. Perhaps it is time to recover that side of the biblical witness, and remind ourselves that there are more ways of representing the world to each other than positivism has ever dreamt.

As we discussed yesterday, the most dramatic innovation yet observed in the E. coli Long Term Evolution Experiment (LTEE) was the ability, acquired by one of the twelve cultures, to use citrate as a carbon source under aerobic conditions. When we last discussed the LTEE in 2011, we noted what was known then about the mutations that eventually combined to produce the Cit+ trait:

Tracking down the nature of this dramatic change led to some interesting findings. The ability to use citrate as a food source did not arise in a single step, but rather as a series of steps, some of which are separated by thousands of generations:

1. The first step is a mutation that arose at around generation 20,000. This mutation on its own does not allow the bacteria to use citrate, but without this mutation in place, later generations cannot evolve the ability to use citrate. Lenski and colleagues were careful to determine that this mutation is not simply a mutation that increases the background mutation rate. In other words, a portion of what later becomes “specified information for using citrate” arises thousands of generations before citrate is ever used.
2. The earliest mutants that can use citrate as a food source do so very, very poorly – once they use up the available glucose, they take a long time to switch over to using citrate. These “early adopters” are a tiny fraction of the overall population. The “specified information for using citrate” at this stage is pretty poor.
3. Once the (poor) ability to use citrate shows up, other mutations arise that greatly improve this new ability. Soon, bacteria that use citrate dominate the population. The “specified information for using citrate” has now been honed by further mutation and natural selection.
4. Despite the “takeover”, a fraction of the population unable to use citrate persists as a minority. These cells eke out a living by being “glucose specialists” – they are better at using up glucose rapidly and then going into stasis before the slightly slower citrate-eaters catch up. So, new “specified information to get the glucose quickly before those pesky citrate-eaters do” allows these bacteria to survive. As such, the two lineages in this population have partitioned the available resources and now occupy two different ecological niches in the same environment. As such, they are well on their way to becoming different bacterial species.

As such, we noted three distinct steps observed by the Lenski group: steps they call potentiation, actualization, and refinement. Potentiation mutations do not themselves result in the ability to use citrate under aerobic conditions, but they are necessary for it to appear later. Actualization is the mutation that first brings about the Cit+ trait, though, as we noted, this step produced only a very weak Cit+ effect. This nascent ability, however, then undergoes refinement through additional mutations and selection to give the final, robust Cit+ trait observed in the culture.

While some things were known about these steps when the Lenski group last published on this topic (in 2008), the precise details remained unclear. What was needed was a complete characterization of the Cit+ bacteria through whole-genome sequencing to help indentify the changes. These long-awaited results are now available in a new paper published last month by the Lenski group, and they shed light on all three stages of the process.

Lights, camera, actualization

The key step - and the one of greatest interest - is of course actualization: the mutation that converted a Cit- cell to a Cit+ one. This is also one of the easiest steps to study, since the mutation provides the cell with a new feature that can be detected experimentally. Though E. coli cannot use citrate as a carbon source in the presence of oxygen, they are capable of using citrate in anoxic conditions (i.e. when oxygen is absent). To do so, they employ a protein that imports citrate in to the cell while at the same time exporting a compound called succinate. Since this protein is already present in the E. coli genome, it was long suspected that a genetic regulatory change that turned on its production in the presence of oxygen could be the key innovation that produced the first Cit+ bacterium in the culture. As we discussed yesterday, Behe notes that this change could result from a loss-of-FCT or a gain-of-FCT mutation:

“If the phenotype of the Lenski Cit+ strain is caused by the loss of the activity of a normal genetic regulatory element, such as a repressor binding site or other FCT, it will, of course, be a loss-of-FCT mutation, despite its highly adaptive effects in the presence of citrate. If the phenotype is due to one or more mutations that result in, for example, the addition of a novel genetic regulatory element, gene duplication with sequence divergence, or the gain of a new binding site, then it will be a noteworthy gain-of-FCT mutation.”

Interestingly, the actualization mutation was indeed a change of regulation of the anoxic citrate / succinate transporter, and it arose through a gain-of-FCT mutation. The mutation turned out to be a side-by-side duplication of the citrate / succinate transporter gene, as well as portions of two genes on either side of it. This imprecise duplication placed a partial fusion of these flanking genes next door to one of the copies of the citrate / succinate transporter gene. This brought the copy under the control of promoter sequences derived from of one of its neighbors, a gene that is active when oxygen is present. The resulting product was a copy of the citrate / succinate transporter gene that was now very weakly expressed in aerobic conditions. Since this is an example of a mutation that duplicates a gene and simultaneously creates a new regulatory element for it (causing significant sequence divergence), this is a clear-cut example of a gain-of-FCT mutation.

Responding to the data

While Behe has not yet, to my knowledge commented on this particular development within the LTEE, one of his colleagues in the Intelligent Design Movement (IDM), microbiologist Ann Gauger, has offered her thoughts. Two themes emerge in her commentary: that the Cit+ trait is “not new”, and that the number of mutations it required were within the bounds set out by Behe and another member of the IDM, structural biologist Douglas Axe:

When is an innovation not an innovation? If by innovation you mean the evolution of something new, a feature not present before, then it would be stretching it to call the trait described by Blount et al. in "Genomic analysis of a key innovation in an experimental Escherichia coli population" an innovation [...]

The total number of mutations postulated for this adaptation is two or three, within the limits proposed for complex adaptations by Axe (2010) and Behe in Edge of Evolution. Because the enabling pre-adaptive mutations could not be identified, though, we don't know whether this was one mutation, a simple step-wise series of adaptive mutations, or a complex adaptation requiring one or two pre-adaptations before the big event.

But does this adaptation constitute a genuine innovation? That depends on the definition of innovation you use. It certainly is an example of reusing existing information in a new context, thus producing a new niche for E. coli in lab cultures. But if the definition of innovation is something genuinely new, such as a new transport molecule or a new enzyme, then no, this adaptation falls short as an innovation. And no one should be surprised.

While Gauger does not speak to the tension between her description of the Cit+ mutation as “not genuinely new” and Behe’s criteria that this should be classified as a gain-of-FCT mutation, it is clear that she views this event as within Behe’s “edge” – i.e. within the bounds of “what Darwinism can do.” Additionally, she sees it as falling within the scope of what is evolutionarily possible as proposed by Axe’s work. In the next installment of this series, we’ll revisit how Behe defines his (claimed) limit of what evolutionary processes can accomplish, with this new evidence in hand. In doing so, a careful examination of the potentiation and refinement phases of the Cit+ transition will be informative.

La visione di BioLogos asserisce che sia le Sacre Scritture, sia la scienza moderna rivelano la Verità, e che queste due verità non sono in contraddizione l’una con l’altra. Mentre da un lato ci sono differenti visioni all’interno della comunità di BioLogos su come riconciliare le verità della scienza con le verità delle Sacre Scritture per quanto riguarda alcuni argomenti specifici (ad esempio in relazione alla storicità della figura di Adamo¹), crediamo concordemente che la Bibbia sia la Parola di Dio, autorevole e divinamente inspirata. BioLogos accetta il moderno consenso scientifico sull’età della Terra e la teoria del progenitore comune, incluso il progenitore comune degli esseri umani.

Evoluzionismo

Mentre da un lato BioLogos accetta l’evoluzione, dall’altro rifiuta totalmente l’Evoluzionismo, ovvero la visione atea del mondo che così spesso accompagna l’accettazione dell’evoluzione biologica nei discorsi pubblici. Coloro che propongono l’Evoluzionismo credono che ogni aspetto della vita sarà un giorno spiegato tramite la teoria dell’evoluzione. In questo modo L’Evoluzionismo è un sottocaso dello scientismo, una più ampia visione secondo la quale l’unica reale verità è quella che può essere scoperta dalla scienza. Sono queste le posizioni tenute comunemente dai materialisti (anche chiamati naturalisti filosofici) che negano l’esistenza del sovrannaturale.

La visione di BioLogos celebra Dio come il Creatore. Qualche volta viene chiamata Evoluzione Teistica o Creazione Evolutiva. Il Teismo è il credere in un Dio a cui sta a cuore il creato e che interagisce con esso. Il Teismo è diverso dal deismo, che indica la convinzione dell’esistenza di un creatore distante e non direttamente coinvolto con l’universo, che spesso è poco più della somma totale delle leggi della fisica. L’Evoluzione Teistica, perciò, è la convinzione che l’evoluzione sia il mezzo con cui Dio ha creato la vita.

Poiché il termine evoluzione è talvolta associato all’ateismo, un termine che meglio descrive il credere in un Dio che ha scelto di creare il mondo per mezzo dell’evoluzione è BioLogos. BioLogos deriva dalle parole greche bios (vita) e logos (parola), riferendosi a Giovanni 1:1: “Nel principio c’era la Parola, e la Parola era presso Dio, e la Parola era Dio”.

Disegno Intelligente

Al contrario di alcune interpretazioni, il Disegno Intelligente (o ID, dall’inglese Intelligent Design) non fa nessuna specifica affermazione teologica. Al contrario, coloro che propongono l’ID argomentano che “determinate caratteristiche dell’universo e degli esseri viventi sono meglio spiegate da una causa intelligente, piuttosto che da un processo indiretto come la selezione naturale”², e che l’esistenza di questa causa intelligente è una ipotesi scientificamente testabile. Inoltre, i teorici del Disegno Intelligente tentano di dimostrare che una causa intelligente è la migliore spiegazione di certi fenomeni come i sistemi irriducibilmente complessi (ad esempio i “flagelli” batterici) le specifiche e complesse informazioni contenute nel DNA.

Anche coloro che supportano la visione di BioLogos credono in una causa intelligente. L’universo e tutto ciò che contiene è stato creato ed è sostenuto e governato da Dio:

…in [Cristo] tutte le cose del Cielo e della Terra sono state create, visibili e invisibili …tutte le cose sono state create tramite Lui e da Lui. Egli stesso è prima di tutte le cose e in Lui tutte le cose sono tenute insieme. (Col 1:16,17 NRSV).

BioLogos si differenzia dal movimento del Disegno Intelligente nel senso che noi non abbiamo problemi nel riconoscere la scienza moderna tradizionale. La selezione naturale come descritta da Charles Darwin non è contraria al teismo. Similmente, siamo più che soddisfatti di come la biologia evoluzionista ci informa riguardo al meccanismo di creazione, con la piena consapevolezza che tutto ciò che succede ed è successo capita ed è capitato attraverso l’azione di Dio. Celebriamo la creazione come completamente generata da Dio. Ci meravigliamo della sua bellezza e siamo grati di avere il privilegio di sperimentare la creazione stessa.

BioLogos celebra la realtà dei miracoli, inclusi i miracoli delle Sacre Scritture, ma anche quelli che sperimentiamo nel mondo dei giorni nostri attraverso le preghiere a cui Dio dà ascolto e attraverso l’azione dello Spirito Santo nelle nostre vite. D’altra parte, la dimostrazione di tali azioni sovrannaturali nella storia del mondo è, noi pensiamo, improbabile da provare scientificamente. Ricapitolando, BioLogos differisce dal movimento del Disegno Intelligente in tre aspetti:

1. Siamo scettici riguardo alla possibilità della scienza biologica di provare l’esistenza di un “Disegnatore” intelligente (che noi riteniamo essere il Dio della Bibbia), mentre i sostenitori dell’ID ne sono confidenti
2. Troviamo non convincenti quei tentativi dei teorici del Disegno Intelligente di dimostrare scientificamente le azioni sovrannaturali operate da Dio nella storia naturale, mentre i sostenitori dell’ID credono di averlo già sufficientemente dimostrato
3. Non troviamo nessun motivo biblico per vedere i processi naturali (inclusa la selezione naturale) come qualcosa che ha rimosso Dio dal processo della creazione. E’ tutta una Sua opera ed è tutta stata intelligentemente predefinita. Coloro che credono nel movimento ID per la maggior parte rigettano tutte o alcune delle più importanti conclusioni della teoria dell’evoluzione.

Creazionismo

BioLogos afferma che la Terra e l’universo sono stati creati.

Il Creazionismo, generalmente, si riferisce al credere che la vita sulla Terra è il risultato di un intervento sovrannaturale diretto, concordemente con una interpretazione altamente letterale della Genesi 1-3. Ci sono due correnti principali di Creazionisti, coloro che credono che la Terra sia giovane e coloro che credono che sia antica.

I Creazionisti della Terra Giovane (anche denominati YECs, dall’inglese Young Earth Creationists) ritengono che la Terra abbia dai 6.000 ai 10.000 anni, un quadro derivato dalle genealogie presenti nella Bibbia. Gli YECs credono che il modo più fedele di leggere le Sacre Scritture sia sotto la prospettiva di una creazione durata letteralmente 6 giorni, come descritta nel primo capitolo della Genesi, e inoltre credono letteralmente che una alluvione mondiale, come descritta nella Genesi 6-9, sia stata responsabile dell’aspetto geologico della Terra e della presenza di testimonianze fossili. I sostenitori del Creazionismo della Terra Giovane respingono inoltre l’esistenza di un progenitore comune di tutte le specie e credono che la vita sia stata creata, come essa appare ora, da una azione sovrannaturale. Considerano la “macro-evoluzione” (distinta dalla “micro-evoluzione” intraspecifica) come incompatibile con le Sacre Scritture e alcuni addirittura argomentano che si tratta di una minaccia diretta alla Cristianità.

BioLogos non è d’accordo con il punto di vista dei Creazionisti della Terra Giovane. Questa visione infatti rifiuta le scoperte di quasi tutte le discipline della scienza moderna per arrivare alle sue conclusioni e trascura la rivelazione del magnifico lavoro di creazione da parte di Dio, rivelazione che ci viene donata dalla scienza. Noi riteniamo inoltre che il punto di vista degli YECs nasce da una particolare interpretazione della Genesi, che non tiene conto del complesso contesto culturale e teologico nel quale è stata scritta.

I Creazionisti della Terra Vecchia (anche denominati OECs, dall’inglese Old Earth Creationists) accettano che la Terra e l’universo abbiano miliardi di anni di vita, ma ritengono che questa scoperta sia concorde con una interpretazione alla lettera del primo capitolo della Genesi (spesso interpretando i giorni di creazione come lunghi periodi di tempo oppure immaginando lunghi momenti di pausa tra un giorno della creazione e l’altro). Gli OECs ritengono che la scienza moderna corrisponda strettamente alla narrazione biblica e difendono l’idea che Dio abbia incluso le moderne idee scientifiche nella Bibbia, talvolta attraverso un linguaggio segreto che sarebbe andato perso a causa della audience delle origini. I sostenitori del Creazionismo della Terra Vecchia non accettano la macro-evoluzione ed un comune progenitore per tutte le forme viventi.

BioLogos è in disaccordo con il punto di vista dei Creazionisti della Terra Vecchia. Mentre tale visione da un lato accetta il consenso scientifico riguardo all’idea di una Terra molto antica, dall’altro rigetta i ritrovamenti della genetica moderna, della paleontologia, della biologia dello sviluppo, della biologia dell’evoluzione e di molte altre sotto-discipline biologiche che hanno poco senso se considerate in modo separato dalla macro-evoluzione e dalla teoria del progenitore comune. Inoltre noi crediamo che Dio ha scelto di rivelare se stesso nel contesto della visione del mondo, della cultura e del linguaggio degli autori della Bibbia.

In che cosa i Cristiani sono d’accordo

Nonostante queste differenze, tutti i Cristiani sono d’accordo che il Dio della Bibbia è il Creatore del cielo e della Terra. Siamo d’accordo nell’autorità della Bibbia, anche se siamo in disaccordo su quale sia la migliore interpretazione di alcuni passaggi particolari. Siamo d’accordo nel credere che Dio sia continuamente attivo nel suo sovrano governo dell’universo, anche se siamo in disaccordo su quanto Dio agisca attraverso le leggi naturali piuttosto che tramite miracoli. Siamo uniti nel rifiutare l’Evoluzionismo, anche se abbiamo diverse argomentazioni alla base di tale rifiuto (alcuni rigettano la scienza dell’evoluzione, mentre BioLogos rifiuta il velo di ateismo posto sulla scienza). Siamo concordi sui fondamenti della nostra fede: che tutte le persone hanno peccato e che la salvezza viene solo attraverso la morte e resurrezione di Gesù Cristo. Siamo d’accordo nel ritenere che il Dio della nostra salvezza sia lo stesso Dio che vediamo nelle meraviglie della sua creazione. Quando contempliamo la complessità insita nel DNA, la bellezza di un delfino o la vastità della Via Lattea, possiamo unire i nostri cuori in una accorata lode per il divino Artista che tutto ha creato.

Growing up, David believed that Young Earth Creationism was the Christian position on origins and how God created. As he endeavored to learn more, he was intrigued by Francis Collins book The Language of God because Francis did not present evolution as a rival theory to Christian faith, but as something that described God's method of creation. David studied biblical interpretation and found John Walton's scholarship to be tremendously helpful in understanding the original purpose and intent of the Genesis narrative.

Reflecting on his personal journey, David thinks that it is important that we don't oversimplify questions related to science and faith, but that we explore them deeply in order to understand science in a robust, Christian way.

“The subtitle of From the Dust is “conversations in creation” and this subtitle reflects the primary purpose of the film. The aim is to start a conversation and to open minds to the issues involved in the questions of evolution and creation, but to do so in a fair fashion. I don’t mean that the film takes no position on the issue – the film clearly intends to make a case for evolutionary creation as consistent with the Christian faith, and in fact as the preferred option. But it does so without misrepresenting or vilifying those holding alternative views. […]

I think the film will work best when followed by open discussion over several sessions, preferably led by Christians with expertise in science and theology. This is something I hope to be able to do as opportunities present themselves, but there are many scholars and teachers around the country capable of leading the discussion.”

From Test of Faith:

“This beautifully produced documentary navigates the difficult ground of the creation-evolution debate graciously, honestly and with rigour. […]

The message of From the Dust is that it is possible to be a sincere Bible-believing Christian and accept what we know through science, particularly evolutionary biology. The approach used is to show both sides of the argument, interviewing representatives of different points of view, before coming down firmly on the part of theologians and scientists who see no clash between faith and evolution. In this feature-length documentary, Pettey and his collaborators have combined authoritative interviews with scholars, pastors and teachers with creative visuals and music to produce something that is eminently watchable and should promote helpful discussion among many, both in and outside of the church.”

From the Dust is available now from Highway Media. DVD copies are $20 and Blu Ray copies are $25. Beginning in October, From the Dust will also be a free gift for tax-deductible donations of $50 or more to The BioLogos Foundation.
