William of Saint Thierry (ca. 1085-1148)
Loving you, O God, brings its own reward here on earth, as well as the eternal reward of heaven. And failure to love you, even when we can offer a thousand excuses, brings its own punishment. By becoming mirrors of your love, by wearing the mask of your likeness, and by allowing you to make us perfect, we can know the joy of heaven, even while we abide here on earth. Our consciences are sullied by our many sins; cleanse them, that we may reflect your infinite brightness.
