iceage,
I don't think a fractured church is a sign of inconsistencies in the Bible. It's a matter of interpretation. Let's keep in mind that the Bible wasn't even written in the language most read it in and deals in Philosophical areas that can be hard to grasp. I chalk-up the fracture more to the limited knowledge of the religious than any shortcomings of the religion.
Not even athiests are in agreement on all philosophical points other than there is no God. Similarly, some Christians have a hard time finding common ground other than there is a God. The fact that some athiests are New Agers and some believe in evolution doesn't automatically discount athiesm. I think most people would plainly agree with this until the issue of religion is brought into play.
