Jesus was a radical apocalyptic rabbi who was mythologized after his death. Other than that he was Jewish, lived around Nazareth somewhere in the early 30s, preached the coming of a new kingdom, had followers, was believed to do miracles, and was crucified, it's hard to find the historic figure behind the myth. But whatever it was he was preaching, it doesn't appear to have much to do with Christianity. Christians might as well call themselves Paulites and have done with it.
If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
