The following was written by Jonathan Dudley and originally appeared on Huffington Post, here.

In the evangelical community, the year 2011 has brought a resurgence of debate over evolution. The current issue of Christianity Today asks if genetic discoveries preclude an historical Adam. While BioLogos, the brainchild of NIH director Francis Collins, is seeking to promote theistic evolution among evangelicals, the president of the Southern Baptist Theological Seminary recently argued that true Christians should believe the Earth is only a few thousand years old.

As someone raised evangelical, I realize anti-evolutionists believe they are defending the Christian tradition. But as a seminary graduate now training to be a medical scientist, I can say that, in reality, they’ve abandoned it.

In theory, if not always in practice, past Christian theologians valued science out of the belief that God created the world scientists study. Augustine castigated those who made the Bible teach bad science, John Calvin argued that Genesis reflects a commoner’s view of the physical world, and the Belgic confession likened scripture and nature to two books written by the same author.

These beliefs encouraged past Christians to accept the best science of their day, and these beliefs persisted even into the evangelical tradition. As Princeton Seminary’s Charles Hodge, widely considered the father of modern evangelical theology, put it in 1859: “Nature is as truly a revelation of God as the Bible; and we only interpret the Word of God by the Word of God when we interpret the Bible by science.”

In this analysis, Christians must accept sound science, not because they don’t believe God created the world, but precisely because they do.

Of course, anti-evolutionists claim their rejection of evolution is not a rejection of science. Phillip Johnson, widely considered the leader of the Intelligent Design movement, states that all he’s rejecting is the atheistic lens through which evolutionary scientists view the world. Evolution, he argues, is “based not upon any incontrovertible empirical evidence, but upon a highly philosophical presupposition.”

And to a certain extent, this line of argument makes sense. Science is not a neutral enterprise. Prior beliefs undoubtedly influence interpretation. If one believes God created vertebrates with a similar design plan, one can acknowledge their structural similarities without believing in common descent. No amount of radiocarbon dating evidence will convince someone the Earth is 4.5 billion years old if that person believes God created the world to look old, with the appearance of age.

But beyond a certain point, this reasoning breaks down. Because no amount of talk about “worldviews” and “presuppositions” can change a simple fact: creationism has failed to provide an alternative explanation for the vast majority of evidence explained by evolution.

• It has failed to explain why birds still carry genes to make teeth, whales to make legs, and humans to make tails.

• It has failed to explain why the fossil record proposed by modern scientists can be used to make precise and accurate predictions about the location of transition fossils.

• It has failed to explain why the fossil record demonstrates a precise order, with simple organisms in the deepest rocks and more complex ones toward the surface.

• It has failed to explain why today’s animals live in the same geographical area as fossils of similar species.

• It has failed to explain why, if carnivorous dinosaurs lived at the same time as modern animals, we don’t find the fossils of modern animals in the stomachs of fossilized dinosaurs.

• It has failed to explain the broken genes that litter the DNA of humans and apes but are functional in lower vertebrates.

• It has failed to explain how the genetic diversity we observe among humans could have arisen in a few thousand years from two biological ancestors.

Those who believe God created the world scientists study, even while ignoring most of the data compiled by those who study it, might as well rip dozens of pages out of their Bibles. Because if “nature is as truly a revelation of God as the Bible,” it’s basically the same thing.

Many think the widespread rejection of evolution doesn’t really matter. Evolution is about what happened in the past, the argument goes, so rejecting it doesn’t have an impact on policies we make today. And aside from school curricula, they may be right.

But the belief that scientists can discover truth, and that, once sufficiently debated, challenged and modified, it should be accepted even if it creates tensions for familiar belief systems, has an obvious impact on decisions that are made everyday. And it is that belief Christians reject when they reject evolution.

In doing so, they’ve not only led America astray on questions ranging from the value of stem cell research to the etiology of homosexuality to the causes of global warming. They’ve also abandoned a central commitment of orthodox Christianity.
