I would think it's in the spirit of ToK, at least, even if a lot of what else they teach revolves around evolution in some way. Imo the christian faith is not blind - as blind as believing in the theory of Evolution is. In the spirit of ToK I'll say that the Bible is the most historically accurate document we have, even if not 100%. But I think there's ample evidence that the Bible was actually written around the time that Jesus is claimed to have lived (based on our dating system), and there's good evidence also that there were christians around then, and that it's about when the belief originated. (Looking at conversations between Pliny Sr and Jr. on the persecution of christians in early rome) Moreover, for people to rather die than give up their faith even in the early days - there has to be something to it. So that's where I stand.
