On a related note, after our convo last week I'm half way through
this book on the historical basis of whether Jesus existed, which is pretty interesting stuff.
This is a book that claims from the start that Jesus exists, so that's its viewpoint quite clearly. The author is typically considered as an anti-Christian (for want of a better term) character since he's so outspoken against Christian fundamentalist views, but certainly believes in Jesus himself. Of course being a New Testament scholar means he could have a vested interest in Jesus existing, at least as a historical character.
So far the evidence is pretty compelling. But you know how it is, when you're in the middle of one side's argument it can seem that way, but less so when you hear the other side. I'll read something by Robert Price next who seems to be the most high profile & credible figure on the side of arguing against Jesus' existence.
