And since we never seem to stop talking about religion around here, I've been plowing through the more popular books by Prof Bart Ehlman.
He is a professor and religious scholar who was raised as a fundamentalist Christian, got a Ph.D. in theology, and taught in fundamentalist Christian schools for awhile.
But the deeper he started examining the Old and New Testaments, the more he began to doubt his own beliefs. Today, he considers himself an agnostic, no longer considers himself to be a 'religious' person, and specializes in books that examine the various textual and thematic problems he identifies in the Bible. He doesn't do it in a nasty, Hitchins/Dawkins type way; he wishes he could believe in the Jesus and God of the Bible but simply finds their history and construction incompatible with his beliefs. If you like this story of thing, I recommend:
1. Misquoting Jesus: A very interesting history of New Testament authorship, that makes a compelling case that no one really knows what the original "texts" of the gospels were, since the earliest extant copies are dated no earlier than the 3rd century CE. He also provides compelling examples of how later scribes edited and added on to gospels throughout the years, so that what you read today may bear absolutely no resemblance to the original version of Mark, Luke, Matthew or John.
2. Jesus Interrupted: Here he does a "parallel" study of the four gospels to clearly demonstrate the many contradictions and discrepancies between the four narratives of the Jesus story, making a strong case that each gospel author (none of whom were probably alive when Jesus died) had his or her own agenda in creating their particular version, and that these four are only the ones "chosen" out of hundreds of other stories that never made the biblical "cut."
3. God's Problem: Perhaps his weakest book. Here, he makes the argument that he cannot reconcile the Bible's portrayal of a caring and loving god (if you do everything he says, that is) with a god who allows suffering, genocide, disease, war and evil to exist in the world, especially when so many who died were devout Christians and Jews.
