Many assume, and some triumphantly boast, that the scholarship of the past 150 years has gutted the New Testament gospels and their story of Jesus. And no wonder: Popular articles and documentaries appear every year — often at Christmas and Easter — suggesting that Christian belief rests more on mythology, even on flat-out historical fabrication, than on genuine history. Moreover, a small but noisy movement, mostly among atheists and agnostics on the Internet and mostly disdained by scholars in relevant disciplines, now confidently declares that Jesus himself never existed at all — not even as a merely mortal Jewish teacher or peasant reformer. (See my previous column titled "The evidence for Jesus is early and powerful.")
