Who is Jesus?
I don't think this is a question that would bother an intellectual - one may ask: "who was Jesus?" or "who do you mean when you talk about Jesus?", as ways of clarifying the terms of the conversation. For instance, the conversation would go very differently if the reply were along the lines of "Oh, 'Jesus' is this guy who lives next door to me ... and he pronounces it 'hey zeus'", or "'Jesus' is the name of our rottweiler."
There is a lot of stuff about the historical Jesus, the mythical Jesus, and so on. It seems that Jesus is all things to everybody - pretty much what you'd expect at the center of a major religion.
