There is an interesting discussion shaping up on the atheosphere, among other places. It started with the publication of Did Jesus Exist? by Bart Ehrman. Actually, it was just a bit prior to that. There was an article in the Huffington Post written by Ehrman that provoked a shocked response from Richard Carrier. He then followed up with a full scale review of the book.
Ehrman’s book (which I have not read yet) apparently concludes that Jesus was not a myth, but actually existed. Carrier is a mythicist, concluding that there is little evidence for an historical Jesus. So it’s not surprising that he might disagree with Ehrman. His conclusion, though, is not very dispassionate. In fact it’s downright harsh, to say the least, at times devolving into the personal.
