The spiritual virtue of a sacrament is like light; although it passes among the impure, it is not polluted.
Saint AugustineLet us, on both sides, lay aside all arrogance. Let us not, on either side, claim that we have already discovered the truth. Let us seek it together as something which is known to neither of us. For then only may we seek it, lovingly and tranquilly, if there be no bold presumption that it is already discovered and possessed.
Saint Augustine
