But the greatest astonishment seized him when the old man declared that God was universal love also; hence he who loves man fulfils God's supreme command. But it is not enough to love men of one's own nation, for the God-man shed his blood for all, and found among pagans such elect of his as Cornelius the Centurion; it is not enough either to love those who do good to us, for Christ forgave the Jews who delivered him to death, and the Roman soldiers who nailed him to the cross, we should not only forgive but love those who injure us, and return them good for evil; it is not enough to love the good, we must love the wicked also, since by love alone is it possible to expel from them evil.
