Saintly actions: admirable, but not imitable
We utter something deeper than we realize when we say of such acts that they are admirable, but not imitable. They are not generalizable, universalizable. They are good; indeed, they are the best of all moral acts. But they are good only for him who does them. We are here very far from the Kantian universal with its morality defined as the possibility of making the maxim of an act into a law for all men.
