The truth is ... we have no idea what Jesus said or didn't say. It is a story written long after he may or may not have existed.
I personally believe that someone named Jesus probably did exist. I also think he was simply a human, like you and me, except a bit crazier and narcissitic. I think the story of Jesus today is nothing more than a tall tale. An exaggeration. Like Paul Bunyan, or Johnny Appleseed.
