“I am trying here to prevent anyone from saying the really foolish thing that people often say about Him [Jesus Christ]: ‘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 a level with a 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 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 up with any patronizing nonsense about his being a great human teacher. He has not left that option open to us. He did not intend to.”
