i) Many apostates make a common mistake. And it's an elementary mistake.
Typically, they were raised in a Bible-believing church. Then they took high school biology, or college Biology 101, or read a book by Richard Dawkins or Jerry Coyne. That sort of thing. And they lose their faith.
The rudimentary mistake is to compare two things that operate at different levels. They are comparing the Bible to science, or comparing theology to science. But these aren't directly comparable. There's an obvious sense in which a few pages of Scripture are no match for hundreds of pages of textbook evolutionary biology. Scripture wasn't designed to engage the issue at that level. Same thing with systematic theology.
The proper comparison would be to read two or more science books from opposing viewpoints. Those operate on the same plane. They address the same issues, at the same level of detail or technicality. They adduce prima facie scientific evidence for their respective positions. That's the relevant level of direct comparison and contrast.
ii) It's also striking that apostates like this are often so lop-sided. Having dipped into the evolutionary literature, they refuse to read the opposing literature. They have no intellectual patience for the other side of the argument.
iii) In addition, they cut evolutionary theory lots of slack while they cut creationism no slack. They make many allowances for evolutionary theory. They don't let the difficulties in evolutionary theory faze them. They have faith that if we're just patient, if we wait it out, these challenges will be resolved. Or, if not, that in principle, they must be consistent with evolution. But they don't show the same deference to creationism.
iv) They ask questions until they arrive at evolution. They come to rest with evolution. At that point they stop asking questions. Evolution is unquestionable. They no longer feel the need to keep posing pesky questions and demanding answers. At best, all questions and answers must now take place within the evolutionary paradigm. Ironically, that's the mirror image of many creationists, whom they disdain.
