Coherently I abandon the idea that the Earliest Gospel had necessarily a Jesus killed directly by the Jews (without Pilate). Because it is implicit in the idea that Jesus was killed by the Jews the Judaizing and anti-Gnostic propaganda that Jesus himself was the davidic Christ and the son of the Jewish god.
So while it is a fact that the Christ Myth was a Jewish thing, to say that Jesus was a Jew or killed by Jews or by Pilate was later anti-Gnostic Gospel propaganda.
