What's so important about Ehrman's position on the historicity of Jesus to Christian apologists is that not only does Ehrman insist that Jesus did exist, but Ehrman is an atheist! Since he's an atheist, he cannot be biased toward a real Jesus or so apologists seem to believe. So here we have a distinguished professor of New Testament who believes in a historical Jesus and without a Christian bias, or so we are told.In a society in which people still claim the Holocaust did not happen, and in which there are resounding claims that the American president is, in fact, a Muslim born on foreign soil, is it any surprise to learn that the greatest figure in the history of Western civilization, the man on whom the most powerful and influential social, political, economic, cultural and religious institution in the world — the Christian church — was built, the man worshipped, literally, by billions of people today — is it any surprise to hear that Jesus never even existed?
Question for Debate: But how unbiased is Ehrman really?
Of course, we all have biases that can skew our thinking, but there are many different kinds of bias and different degrees of bias. Some biases can be overcome with sufficient evidence, and other kinds of bias will remain regardless of the evidence. I think it's safe to say that an atheist can indeed have a pro-historical-Jesus bias. After all, depending on your theology, a real Jesus doesn't necessitate a real God. So Ehrman might well have a real-Jesus bias, and his being an atheist does not preclude his having such a bias.
There's plenty more I can say about Ehrman's article, but I will save that for later in the discussion.
