… bodily resurrection was a Palestinian Jewish idea. It is difficult to conceive of a rapidly hellenizing Gentile church preaching a dying-and-rising mystery deity triggering Palestinian Jewish Jesus people to adopt a pagan idea and then modify it in a Palestinian Jewish direction (including the specifically Jewish language of “resurrection”). It is far more likely that later Gentiles attracted to a growing Jewish cult would have adopted and transformed a Palestinian Jewish understanding of the resurrection.

I might add, “like many do today”.
