Merely propounding moral propositions is a necessary condition for one’s being a great moral teacher, but not a sufficient condition. Adolf Hitler could propound moral propositions, my eight-year old son could too, but that would hardly make them a great moral teacher. In order to qualify as a great moral teacher, one’s character is relevant too, not just the content of his teachings. Someone with delusions as severe as those attributed to Jesus on this view would indicate a personality that is so disintegrated as to be disqualified from being considered a great moral teacher. — Paul Gould (from, Was Jesus just a Great Moral Teacher?)
