The spiritual virtue of a sacrament is like light; although it passes among the impure, it is not polluted.
Saint AugustineThe bread that you see on the altar is the Body of Christ as soon as it is sanctified by God's word. The chalice, or better what is contained in the chalice, is the Blood of Christ as soon as it is sanctified by God's word
Saint AugustineFor why, my brothers and sisters, would you rejoice in silver? Either your silver will perish, or you will, and no one knows which will perish first. For neither can you remain here always, nor can silver remain here always; so also with gold, wardrobes, houses, money, real estate-and in the end, even the light by which we enjoy all these things. So do not be willing then to rejoice in such things as these. Rejoice instead in the light that has no setting; rejoice in the dawn which no yesterday precedes, and no tomorrow follows.
Saint Augustine
