>>You pose an interesting question. If someone believes Jesus was a great prophet but not the Son of God, are they Christian?<<

The answer is quite simple: No.

C.S. Lewis pontificates on the point very effectively in “Mere Christianity”. The biggest problem is this: If you think a guy was a great teacher, but you do not believe he was God, yet one of the things that he taught was that he is God, is that not a bit of an intellectual conundrum for you? As lewis points out, Jesus was either God or a lunatic. He left no room to be seen as "just" a great teacher.

I agree with your assessment.
