Coyne is a an excellent evolutionary biologist, frankly much better than Dawkins. He does not know much about the Christian faith. I’d trust him on evolution. No reason to trust him on theology. I honestly see no conflict between my faith and science.
What ever is going on in his book, he is a well respected scientist doing good work.
And that is my point to. He does not really seem to understand Christianity, and why should he any ways? And likewise, how could he know if Christianit and science are compatible?
