Was Jesus a Great Moral Teacher? C S Lewis

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 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 moral teacher. He has not left that option open to us.

He did not intend to.
