Historical Jesus, Biblical Jesus

[Rhythmcs]

If you want to really have fun with it - consider this.  Scrub the imaginary friend bit.  Let's posit that there was a real apparition, and it was really a god.  

What would that have to do with the alleged historical man?

If I understand the point you’re making, I agree. Anything in the gospel stories about Jesus that could be about a real person has nothing to do with the theology of today’s Christian churches. I think that theology is also very different from Paul’s.

(later) Now I'm thinking that maybe your point is that my Jesus story is actually a Christ myth story. Not really, because it's still saying that some of the sayings of Jesus in the gospel stories were taken from stories about a real person who was crucified during the prefecture of Pontius Pilate, and who had some followers who thought that he was a promised king of Israel.

Not so long as The Frank, and the guy that paul thinks is frank, are meaningfully distinct as you described.  That there was anyone who might ever, then-or-later, be conflated with the real god that came as an apparition to paul is only coincidentally true, if true. The essence of a personal god is to be like a person in some way or another, after all.
