“It is a certain truth that all the religions which have existed from the beginning of the world have ever had some sacrifice as an essential part of the worship which they offered to God. But because their whole law was either vain or imperfect, so were their sacrifices either vain or imperfect. Most vain were the sacrifices of the idolaters, nor is there any occasion to mention them; and those of the Hebrews, although, indeed, then professing the true religion, were poor and deficient, by St. Paul called infirma et egena elementa, “weak and poor elements” (Gal. iv. 9), because they could neither cancel sin nor confer grace. The sole sacrifice which we have in our holy religion, that is to say, Holy Mass, is a sacrifice, holy, perfect, in every point complete, with which each one of the faithful nobly honors God, protesting at one and the same time his own nothingness and the supreme dominion which God hath over him; a sacrifice called, therefore, by David, sacrificium justitiae, “the sacrifice of justice” (Ps. iv. 5); both because it contains the Just One Himself, and the Saint of Saints, or rather justice and holiness themselves, and because it sanctifies souls by the infusion of grace and the affluence of gifts which it confers.” -Saint Leonard of Port Maurice, The Hidden Treasure of the Holy Mass
