All conjecture but reasonable enough.
If you start with the premise that Jesus was a real person but not divine, I think the real story would look a lot like that.

I've heard an account, that some Byzantine queen-consort was told by a soothsayer that she (the queen) in her pervious life, was a witch.
So the queen asked/persuaded the king to remove this from Christianity.
