Can I ask you a question. Do you believe the person called Jesus in the gospels existed? I'm not asking if you agree with any of the gospels, just whether or not you believe they were inspired by a real figure.
I see Jesus as an archetypal good man. More like what Joseph Campbell called a hero od 1,000 faces.
I think Gnostic Christianity came out of Chrestianity, --- I cannot prove it, --- which is a good man ideology and not a supernatural god belief.
There are no supernatural beliefs in Gnostic Christianity.
