the time after his death doesnt change anything, all i know is that according to historical facts jesus was born as a jew, and died as one.
I can argue with you till tommorow's morning but jesus dint invent anything new.. All those anti revenge talks appear also in the old testament, in its law part which is the Pentateuch. Even if he was a son of god and a prophet, still he didnt say anything that didnt appear in the Pentateuch, his followers are the people who started the new religion not he himself.
