Thank you very much for your insightful post.
I was born (or made by my parents to become) a Christian too (Catholic), I don't practice it anymore though, in fact I don't practice any religion at this time. But I still think spirituality has it's part to play in the human psyche :)
That said, I would never use any of the teachings of my religion as a point of view to do science. I would keep these two as completely separate thought processes.
I did not know there were some observations that had been predicted by a religion. Even in this case, it would only take one prediction for which we have evidence that it did not happen in the way described, for us to disprove this "prophet". Would it not?
