I recently finished two books, one after the other, about the historical (as opposed to theological) existence of the man we call Jesus. Jesus of Nazareth is the historical man. Jesus Christ in the theological man. The two books, in chronological order (but in my reverse reading order), are Bart Ehrman’s “Did Jesus Exist?: The Historical Argument for Jesus of Nazareth“, and Reza Aslan’s more recent “Zealot: The Life and Times of Jesus of Nazareth“. As you can surmise, both of these books explore the question of who the actual man named Jesus was, as opposed to the myths and religions we’ve created around him. In short, they attempt to analyze the latest historical scholarship about him, while regurgitating it for the layman. In the process they give their own considered opinion about exactly who Jesus was.
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.
