> The only really significant question is the account of James.

One passage. One. In a text, where the other passage is accepted to be forgery, and which comes to us as a copy by Christian scribes. And if it is specifically Carrier that you dismiss, take a look at Nicholas Allen's recent book that I referenced in my previous comment. Allen uses arguments that are independent from Carrier's and comes to a conclusion that is even more radical than his — while Carrier accepts the James passage on the whole and only suggests that the "who was called Christ" line started as a marginal note by a Christian peruser of the text, Allen argues that the whole James passage is a forgery. And he seems to be a modern mainstream scholar trained in philology and ancient and classical history.
