I was wondering when someone would make a move like this. It's an argument that evolution points towards towards the truth of Christianity - not merely theism, but Christianity specifically.
I've only glanced at the argument, and at the moment I think it's very interesting but not strongly persuasive as written. Part of the problem for me is that the author's making a very bold move, which in the process elevates evolution to something that smells like necessity for God. I could be misreading it.
That said, I've actually been waiting for these sorts of arguments to surface for a while - you'd think theistic evolutionists would be making them! Some ID proponents make arguments along these lines, but of course most of them are committed to saying their arguments are scientific rather than philosophical, which means most of the commentary is about the appropriateness of the label rather than the merits of their arguments.
My impression is that most TEs avoid making arguments in that direction largely because so many of them are motivated first and foremost by avoiding conflict, particularly with agnostic to atheist colleagues. The received wisdom on 'avoiding conflict' on that front seems to be to just talk about how awesome science is, how compatible it is with religious belief, and to avoid all greater details about this when possible. (Be sure to wring your hands and talk about how complicated and mysterious everything is!) But make a move to argue how evolution comports with design or theism - or worse, points towards it - and you're pretty much saying "Hello, secularists! I'm here to take your favorite toy away from you and use it in the service of something you dislike and are frankly somewhat afraid of!"
Anyway, it's an interesting move so I thought I'd toss it up here.
