Before conversion, conscience seemed to be a restraining, coercive power; God was a hostile and exacting judge; the commandments were prohibitions: and the Church was an inhibition. Responsibilities were identified with obligation; duty was seen as opposed to desire; the morally right was identified with the physically unpleasant; and love was opposed to morality. But after conversion the conscience no longer accuses; it never seems to command, or order, or inhibit, because there are no longer two wills in opposition. The will of the convert is the will of God. There is no need for a conscience to tell him what “ought to be done.” Conscience is swallowed up in love, and there is no duty or “must” between lovers.
--Archbishop Fulton J. Sheen, Peace of Soul, 1949
