Michael Grant doesn’t know that extraordinary claims require extraordinary evidence. Saying that we know that there was some king in a certain place and time isn’t a big claim. Most places had kings. Saying that if even a quarter of the claims of the Gospels were true is a massive claim. Also whataboutism is kinda boring. I really don’t feel giving “historians” slack because they cut themselves slack.
In modern scholarship, the Christ myth theory is a fringe theory and finds virtually no support from scholars
Not going to have a job selling book and teaching the story of some old con. You sell books by advancing dozens of different contradictory models of the events all of them equally impossible to test.
