Ehrman will debate this issue to raise funds for his pet charities. It looks like $13,000 is required for the debate to take place. You can donate to make it happen right here, where you'll see a video from the two participants describing their views, along with an itemized list of the money required. Although agreeing to this debate, Ehrman says:
The question is not really a matter of dispute among experts, even though mythicists as a rule would like it to be and sometimes even insist it is. But the reality is this: if you were to look at the program of the annual meeting of (the many thousands of English-speaking) professors of Biblical Studies, the Society of Biblical Literature meeting (this year in Atlanta), you will not find a session (out of thousands) devoted to arguing both sides of this issue. That’s because there is no debate. LINK.There are some signs this is not as rock solid of a consensus as Ehrman makes it out to be. For Richard Carrier has defended Jesus mythicism in a book published by Sheffield Phoenix Press, the most prestigious Christian scholarly publisher around, On the Historicity of Jesus: Why We Might Have Reason for Doubt. His massive book is a magisterial treasure trove of research and information. There is a minor difficulty in using Bayesian math to establish something in the past, which seems quite fashionable right now in some circles. For my part I don't have a stake in who wins this debate, so long as both sides agree that the Jesus depicted in the Gospels never existed.
