"A good act, while fully our own, is good only because it comes entirely from God, being the act of God before being ours. An evil act, on the other hand, is such to the extent in which our action is no longer fully the action of God."
Louis Bouyer, Woman and man with God: an essay on the place of the Virgin Mary in Christian theology and its significance for humanity, trans. Fr. A. V. Littledale (London: Darton, Longman & Todd, 1960 ), 110.
