Well I believe He did, because I accept the testimonies of the disciples and the evangelists. To me, it's their experience of meeting and walking with Christ (and that includes Paul).
I accept the evangelists are anonymous, and perhaps writing at a one-step remove. I accept that they added and embellished, their their narratives follow the pattern of mythic narratives of the day, they they sit comfortably in GrecoRoman literature. That Paul was deeply influenced by Jewish Merkabah Mysticism. But I see no reason to assume that diminishes the Message, or that he, or they, got it wrong.
They all got it differently, but they're all essentially right.
I'm not against you, I'm just trying to point out that while your thesis is credible, it lacks credibility and, based on the fact that there's no evidence to support it, there's no reason why anyone should entertain it as anything other than your version of what could have happened.
