Open debate: What does Jesus teach?

[Mudhammam]

The crucifixion isn't exactly coming out of left field. They had to slaughter their sacrificial lamb somehow. They don't seem to have been interested in continuing on in their "jewishness" such as it was. Ask the jews.

I think that goes more to the OP's point, and one that Nietzsche succinctly made in his excellent work, The Anti-Christ: Paul, for whatever reason, forsook a large degree of his heritage and re-wrote Jesus for a non-Jewish audience; he himself repeatedly makes clear that that was his purpose. And in the process, he mutated and distorted the original Gospel, which was VERY Jewish, and was originally intended for Jews (whereas again, a crucified Messiah was extremely antithetical to traditional Jewish beliefs, the OT being interpreted very liberally by Jesus' followers after the fact).
