The idea of Jesus as antichrist is just too mind-boggling for words, though I suppose it adds up etymologically.

Of course, if he was just some guy, then isn't the spreading mostly Paul's domain? (Of course, if Paul had stayed out of it, maybe the result would have been a bunch of largely observant Jews who happened to have a conviction that their dead messiah was unprecedentedly awesome to some disputed degree, and coming back.)
