Sometime in the mid 70s AD, Atwill suggests, Greco-Roman intellectuals wrote the now-well-known stories—in Greek, not the popular Aramaic of the Judaic populace—about the Jewish messiah who defied the Judaic traditions of militancy to preach a sweet, accommodationist message.
Explained in better detail better here, but the fake historical Jesus theories arrive and depart in Internet-rhythm cycles with varying degrees of marketing stickiness and profitability, due to the abbreviated long-term memory of consumers and a circadian need for world-scale scandal. The last really profitable one was the The da Vinci Code installment—other ones haven’t fared as well, I think. I don’t prefer to keep close track of rehashed material.
But if the evidence is “overwhelming” (evidence that scholars for centuries have somehow missed), the amount of ‘splainin’ to do is of equal magnitude. Immense, undeniable revisionism doesn’t sprout in a vacuum—there’s a despot’s harem-sized ton of things that need to be explained via logic at the first level, then historically at the next level, before they can be taken seriously.
