"It is no good asking for a simple religion. After all, real things are not simple.

'I'm ready to accept Jesus as a great moral teacher, but I don't accept His claim to be God'... 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 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 patronising nonsense about His being a great human teacher. He has not left that open to us. He did not intend to."
