“Christ opposed it (external moral purity) in a radical manner: nothing makes a man unclean ‘from the outside’; no ‘material’ dirtiness makes a man impure in a moral sense. No washing, not even ritual washing, is by itself suited to produce moral purity. Moral purity has its wellspring exclusively in man’s interior: it comes from the heart.”
