Summa Theologica I-II, q. 102: Of the Causes of the Ceremonial Precepts
Article 3. Whether a suitable cause can be assigned for the ceremonies which pertained to sacrifices?
Objection 1It would seem that no suitable cause can be assigned for the ceremonies pertaining to sacrifices. For those things which were offered in sacrifice, are those which are necessary for sustaining human life: such as certain animals and certain loaves. But God needs no such sustenance; according to Ps. 49:13: "Shall I eat the flesh of bullocks? Or shall I drink the blood of goats?" Therefore such sacrifices were unfittingly offered to God.
Objection 2Further, only three kinds of quadrupeds were offered in sacrifice to God, viz. oxen, sheep and goats; of birds, generally the turtledove and the dove; but specially, in the cleansing of a leper, an offering was made of sparrows. Now many other animals are more noble than these. Since therefore whatever is best should be offered to God, it seems that not only of these three should sacrifices have been offered to Him.
Objection 3Further, just as man has received from God the dominion over birds and beasts, so also has he received dominion over fishes. Consequently it was unfitting for fishes to be excluded from the divine sacrifices.
Objection 4Further, turtledoves and doves indifferently are commanded to be offered up. Since then the young of the dove are commanded to be offered, so also should the young of the turtledove.
Objection 5Further, God is the Author of life, not only of men, but also of animals, as is clear from Gn. 1:20, seqq. Now death is opposed to life. Therefore it was fitting that living animals rather than slain animals should be offered to God, especially as the Apostle admonishes us (Rom. 12:1), to present our bodies "a living sacrifice, holy, pleasing unto God."
Objection 6Further, if none but slain animals were offered in sacrifice to God, it seems that it mattered not how they were slain. Therefore it was unfitting that the manner of immolation should be determined, especially as regards birds (Lev. 1:15, seqq.).
Objection 7Further, every defect in an animal is a step towards corruption and death. If therefore slain animals were offered to God, it was unreasonable to forbid the offering of an imperfect animal, e.g. a lame, or a blind, or otherwise defective animal.
Objection 8Further, those who offer victims to God should partake thereof, according to the words of the Apostle (1 Cor. 10:18): "Are not they that eat of the sacrifices partakers of the altar?" It was therefore unbecoming for the offerers to be denied certain parts of the victims, namely, the blood, the fat, the breastbone and the right shoulder.
Objection 9Further, just as holocausts were offered up in honor of God, so also were the peace-offerings and sin-offerings. But no female animal was offered up to God as a holocaust, although holocausts were offered of both quadrupeds and birds. Therefore it was inconsistent that female animals should be offered up in peace-offerings and sin-offerings, and that nevertheless birds should not be offered up in peace-offerings.
Objection 10Further, all the peace-offerings seem to be of one kind. Therefore it was unfitting to make a distinction among them, so that it was forbidden to eat the flesh of certain peace-offerings on the following day, while it was allowed to eat the flesh of other peace-offerings, as laid down in Lev. 7:15, seqq.
Objection 11Further, all sins agree in turning us from God. Therefore, in order to reconcile us to God, one kind of sacrifice should have been offered up for all sins.
Objection 12Further, all animals that were offered up in sacrifice, were offered up in one way, viz. slain. Therefore it does not seem to be suitable that products of the soil should be offered up in various ways; for sometimes an offering was made of ears of corn, sometimes of flour, sometimes of bread, this being baked sometimes in an oven, sometimes in a pan, sometimes on a gridiron.
Objection 13Further, whatever things are serviceable to us should be recognized as coming from God. It was therefore unbecoming that besides animals, nothing but bread, wine, oil, incense, and salt should be offered to God.
Objection 14Further, bodily sacrifices denote the inward sacrifice of the heart, whereby man offers his soul to God. But in the inward sacrifice, the sweetness, which is denoted by honey, surpasses the pungency which salt represents; for it is written (Ecclus. 24:27): "My spirit is sweet above honey." Therefore it was unbecoming that the use of honey, and of leaven which makes bread savory, should be forbidden in a sacrifice; while the use was prescribed, of salt which is pungent, and of incense which has a bitter taste. Consequently it seems that things pertaining to the ceremonies of the sacrifices have no reasonable cause.
On the contraryIt is written (Lev. 1:13): "The priest shall offer it all and burn it all upon the altar, for a holocaust, and most sweet savor to the Lord." Now according to Wis. 7:28, "God loveth none but him that dwelleth with wisdom": whence it seems to follow that whatever is acceptable to God is wisely done. Therefore these ceremonies of the sacrifices were wisely done, as having reasonable causes.
I answer thatAs stated above (A[2]), the ceremonies of the Old Law had a twofold cause, viz. a literal cause, according as they were intended for Divine worship; and a figurative or mystical cause, according as they were intended to foreshadow Christ: and on either hand the ceremonies pertaining to the sacrifices can be assigned to a fitting cause.
For, according as the ceremonies of the sacrifices were intended for the divine worship, the causes of the sacrifices can be taken in two ways. First, in so far as the sacrifice represented the directing of the mind to God, to which the offerer of the sacrifice was stimulated. Now in order to direct his mind to God aright, man must recognize that whatever he has is from God as from its first principle, and direct it to God as its last end. This was denoted in the offerings and sacrifices, by the fact that man offered some of his own belongings in honor of God, as though in recognition of his having received them from God, according to the saying of David (1 Paral. xxix, 14): "All things are Thine: and we have given Thee what we received of Thy hand." Wherefore in offering up sacrifices man made protestation that God is the first principle of the creation of all things, and their last end, to which all things must be directed. And since, for the human mind to be directed to God aright, it must recognize no first author of things other than God, nor place its end in any other; for this reason it was forbidden in the Law to offer sacrifice to any other but God, according to Ex. 22:20: "He that sacrificeth to gods, shall be put to death, save only to the Lord." Wherefore another reasonable cause may be assigned to the ceremonies of the sacrifices, from the fact that thereby men were withdrawn from offering sacrifices to idols. Hence too it is that the precepts about the sacrifices were not given to the Jewish people until after they had fallen into idolatry, by worshipping the molten calf: as though those sacrifices were instituted, that the people, being ready to offer sacrifices, might offer those sacrifices to God rather than to idols. Thus it is written (Jer. 7:22): "I spake not to your fathers and I commanded them not, in the day that I brought them out of the land of Egypt, concerning the matter of burnt-offerings and sacrifices."
