“I am trying here to prevent anyone saying the really foolish thing that people often say about Him: I’m ready to accept Jesus as a great moral teacher, but I don’t accept his claim to be God.  That is the one thing we must not say.  A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher.  He would either be a lunatic — on the level with the man who says he is a poached egg — or else he would be the Devil of Hell.  You must make your choice.  Either this man was, and is, the Son of God, or else a madman or something worse.  You can shut him up for a fool, you can spit at him and kill him as a demon or you can fall at his feet and call him Lord and God, but let us not come with any patronizing nonsense about his being a great human teacher.  He has not left that open to us. He did not intend to.”

(C.S. Lewis in Mere Christianity)
