[I-II.q.103.a.1.arg.1] It would seem that the ceremonies of the Law were in existence before the Law. For sacrifices and holocausts were ceremonies of the Old Law, as stated above (Question 101, Article 4). But sacrifices and holocausts preceded the Law: for it is written (Genesis 4:3-4) that "Cain offered, of the fruits of the earth, gifts to the Lord," and that "Abel offered of the firstlings of his flock, and of their fat." Noah also "offered holocausts" to the Lord (Genesis 18:20), and Abraham did in like manner (Genesis 22:13). Therefore the ceremonies of the Old Law preceded the Law.

[I-II.q.103.a.1.arg.2] Further, the erecting and consecrating of the altar were part of the ceremonies relating to holy things. But these preceded the Law. For we read (Genesis 13:18) that "Abraham . . . built . . . an altar to the Lord"; and (Genesis 28:18) that "Jacob . . . took the stone . . . and set it up for a title, pouring oil upon the top of it." Therefore the legal ceremonies preceded the Law.

[I-II.q.103.a.1.arg.3] Further, the first of the legal sacraments seems to have been circumcision. But circumcision preceded the Law, as appears from Genesis 17. In like manner the priesthood preceded the Law; for it is written (Genesis 14:18) that "Melchisedech . . . was the priest of the most high God." Therefore the sacramental ceremonies preceded the Law.

[I-II.q.103.a.1.arg.4] Further, the distinction of clean from unclean animals belongs to the ceremonies of observances, as stated above (100, 2, 6, ad 1). But this distinction preceded the Law; for it is written (Genesis 7:2-3): "Of all clean beasts take seven and seven . . . but of the beasts that are unclean, two and two." Therefore the legal ceremonies preceded the Law.

[I-II.q.103.a.1.sc] It is written (Deuteronomy 6:1): "These are the precepts and ceremonies . . . which the Lord your God commanded that I should teach you." But they would not have needed to be taught about these things, if the aforesaid ceremonies had been already in existence. Therefore the legal ceremonies did not precede the Law.

[I-II.q.103.a.1.co] As is clear from what has been said (101, 2; 102, 2), the legal ceremonies were ordained for a double purpose; the worship of God, and the foreshadowing of Christ. Now whoever worships God must needs worship Him by means of certain fixed things pertaining to external worship. But the fixing of the divine worship belongs to the ceremonies; just as the determining of our relations with our neighbor is a matter determined by the judicial precepts, as stated above (Question 99, Article 4). Consequently, as among men in general there were certain judicial precepts, not indeed established by Divine authority, but ordained by human reason; so also there were some ceremonies fixed, not by the authority of any law, but according to the will and devotion of those that worship God. Since, however, even before the Law some of the leading men were gifted with the spirit of prophecy, it is to be believed that a heavenly instinct, like a private law, prompted them to worship God in a certain definite way, which would be both in keeping with the interior worship, and a suitable token of Christ's mysteries, which were foreshadowed also by other things that they did, according to 1 Corinthians 10:11: "All . . . things happened to them in figure." Therefore there were some ceremonies before the Law, but they were not legal ceremonies, because they were not as yet established by legislation.

[I-II.q.103.a.1.ad.1] The patriarchs offered up these oblations, sacrifices and holocausts previously to the Law, out of a certain devotion of their own will, according as it seemed proper to them to offer up in honor of God those things which they had received from Him, and thus to testify that they worshipped God Who is the beginning and end of all.

[I-II.q.103.a.1.ad.2] They also established certain sacred things, because they thought that the honor due to God demanded that certain places should be set apart from others for the purpose of divine worship.

[I-II.q.103.a.1.ad.3] The sacrament of circumcision was established by command of God before the Law. Hence it cannot be called a sacrament of the Law as though it were an institution of the Law, but only as an observance included in the Law. Hence Our Lord said (John 7:20) that circumcision was "not of Moses, but of his fathers." Again, among those who worshipped God, the priesthood was in existence before the Law by human appointment, for the Law allotted the priestly dignity to the firstborn.

[I-II.q.103.a.1.ad.4] The distinction of clean from unclean animals was in vogue before the Law, not with regard to eating them, since it is written (Genesis 9:3): "Everything that moveth and liveth shall be meat for you": but only as to the offering of sacrifices because they used only certain animals for that purpose. If, however, they did make any distinction in regard to eating; it was not that it was considered illegal to eat such animals, since this was not forbidden by any law, but from dislike or custom: thus even now we see that certain foods are looked upon with disgust in some countries, while people partake of them in others.

[I-II.q.103.a.2.arg.1] It would seem that the ceremonies of the Old Law had the power of justification at the time of the Law. Because expiation from sin and consecration pertains to justification. But it is written (Exodus 39:21) that the priests and their apparel were consecrated by the sprinkling of blood and the anointing of oil; and (Leviticus 16:16) that, by sprinkling the blood of the calf, the priest expiated "the sanctuary from the uncleanness of the children of Israel, and from their transgressions and . . . their sins." Therefore the ceremonies of the Old Law had the power of justification.

[I-II.q.103.a.2.arg.2] Further, that by which man pleases God pertains to justification, according to Psalm 10:8: "The Lord is just and hath loved justice." But some pleased God by means of ceremonies, according to Leviticus 10:19: "How could I . . . please the Lord in the ceremonies, having a sorrowful heart?" Therefore the ceremonies of the Old Law had the power of justification.

[I-II.q.103.a.2.arg.3] Further, things relating to the divine worship regard the soul rather than the body, according to Psalm 18:8: "The Law of the Lord is unspotted, converting souls." But the leper was cleansed by means of the ceremonies of the Old Law, as stated in Leviticus 14. Much more therefore could the ceremonies of the Old Law cleanse the soul by justifying it.

[I-II.q.103.a.2.sc] The Apostle says (Galatians 2) [The first words of the quotation are from 3:21: St. Thomas probably quoting from memory, substituted them for 2:21, which runs thus: 'If justice be by the Law, then Christ died in vain.']: "If there had been a law given which could justify [Vulgate: 'give life'], Christ died in vain," i.e. without cause. But this is inadmissible. Therefore the ceremonies of the Old Law did not confer justice.

[I-II.q.103.a.2.co] As stated above (102, 5, ad 4), a twofold uncleanness was distinguished in the Old Law. One was spiritual and is the uncleanness of sin. The other was corporal, which rendered a man unfit for divine worship; thus a leper, or anyone that touched carrion, was said to be unclean: and thus uncleanness was nothing but a kind of irregularity. From this uncleanness, then, the ceremonies of the Old Law had the power to cleanse: because they were ordered by the Law to be employed as remedies for the removal of the aforesaid uncleannesses which were contracted in consequence of the prescription of the Law. Hence the Apostle says (Hebrews 9:13) that "the blood of goats and of oxen, and the ashes of a heifer, being sprinkled, sanctify such as are defiled, to the cleansing of the flesh." And just as this uncleanness which was washed away by such like ceremonies, affected the flesh rather than the soul, so also the ceremonies themselves are called by the Apostle shortly before (Hebrews 9:10) justices of the flesh: "justices of the flesh," says he, "being laid on them until the time of correction."

On the other hand, they had no power of cleansing from uncleanness of the soul, i.e. from the uncleanness of sin. The reason of this was that at no time could there be expiation from sin, except through Christ, "Who taketh away the sins [Vulgate: 'sin'] of the world" (John 1:29). And since the mystery of Christ's Incarnation and Passion had not yet really taken place, those ceremonies of the Old Law could not really contain in themselves a power flowing from Christ already incarnate and crucified, such as the sacraments of the New Law contain. Consequently they could not cleanse from sin: thus the Apostle says (Hebrews 10:4) that "it is impossible that with the blood of oxen and goats sin should be taken away"; and for this reason he calls them (Galatians 4:9) "weak and needy elements": weak indeed, because they cannot take away sin; but this weakness results from their being needy, i.e. from the fact that they do not contain grace within themselves.

However, it was possible at the time of the Law, for the minds of the faithful, to be united by faith to Christ incarnate and crucified; so that they were justified by faith in Christ: of which faith the observance of these ceremonies was a sort of profession, inasmuch as they foreshadowed Christ. Hence in the Old Law certain sacrifices were offered up for sins, not as though the sacrifices themselves washed sins away, but because they were professions of faith which cleansed from sin. In fact, the Law itself implies this in the terms employed: for it is written (Leviticus 4:26; 5:16) that in offering the sacrifice for sin "the priest shall pray for him . . . and it shall be forgiven him," as though the sin were forgiven, not in virtue of the sacrifices, but through the faith and devotion of those who offered them. It must be observed, however, that the very fact that the ceremonies of the Old Law washed away uncleanness of the body, was a figure of that expiation from sins which was effected by Christ.

It is therefore evident that under the state of the Old Law the ceremonies had no power of justification.

[I-II.q.103.a.2.ad.1] That sanctification of priests and their sons, and of their apparel or of anything else belonging to them, by sprinkling them with blood, had no other effect but to appoint them to the divine worship, and to remove impediments from them, "to the cleansing of the flesh," as the Apostle states (Hebrews 9:13) in token of that sanctification whereby "Jesus" sanctified "the people by His own blood" (Hebrews 13:12). Moreover, the expiation must be understood as referring to the removal of these bodily uncleannesses, not to the forgiveness of sin. Hence even the sanctuary which could not be the subject of sin is stated to be expiated.

[I-II.q.103.a.2.ad.2] The priests pleased God in the ceremonies by their obedience and devotion, and by their faith in the reality foreshadowed; not by reason of the things considered in themselves.

[I-II.q.103.a.2.ad.3] Those ceremonies which were prescribed in the cleansing of a leper, were not ordained for the purpose of taking away the defilement of leprosy. This is clear from the fact that these ceremonies were not applied to a man until he was already healed: hence it is written (Leviticus 14:3-4) that the priest, "going out of the camp, when he shall find that the leprosy is cleansed, shall command him that is to be purified to offer," etc.; whence it is evident that the priest was appointed the judge of leprosy, not before, but after cleansing. But these ceremonies were employed for the purpose of taking away the uncleanness of irregularity. They do say, however, that if a priest were to err in his judgment, the leper would be cleansed miraculously by the power of God, but not in virtue of the sacrifice. Thus also it was by miracle that the thigh of the adulterous woman rotted, when she had drunk the water "on which" the priest had "heaped curses," as stated in Numbers 5:19-27.

[I-II.q.103.a.4.arg.1] It would seem that since Christ's Passion the legal ceremonies can be observed without committing mortal sin. For we must not believe that the apostles committed mortal sin after receiving the Holy Ghost: since by His fulness they were "endued with power from on high" (Luke 24:49). But the apostles observed the legal ceremonies after the coming of the Holy Ghost: for it is stated (Acts 16:3) that Paul circumcised Timothy: and (Acts 21:26) that Paul, at the advice of James, "took the men, and . . . being purified with them, entered into the temple, giving notice of the accomplishment of the days of purification, until an oblation should be offered for every one of them." Therefore the legal ceremonies can be observed since the Passion of Christ without mortal sin.

[I-II.q.103.a.4.arg.2] Further, one of the legal ceremonies consisted in shunning the fellowship of Gentiles. But the first Pastor of the Church complied with this observance; for it is stated (Galatians 2:12) that, "when" certain men "had come" to Antioch, Peter "withdrew and separated himself" from the Gentiles. Therefore the legal ceremonies can be observed since Christ's Passion without committing mortal sin.

[I-II.q.103.a.4.arg.3] Further, the commands of the apostles did not lead men into sin. But it was commanded by apostolic decree that the Gentiles should observe certain ceremonies of the Law: for it is written (Acts 15:28-29): "It hath seemed good to the Holy Ghost and to us, to lay no further burden upon you than these necessary things: that you abstain from things sacrificed to idols, and from blood, and from things strangled, and from fornication." Therefore the legal ceremonies can be observed since Christ's Passion without committing mortal sin.

[I-II.q.103.a.4.sc] The Apostle says (Galatians 5:2): "If you be circumcised, Christ shall profit you nothing." But nothing save mortal sin hinders us from receiving Christ's fruit. Therefore since Christ's Passion it is a mortal sin to be circumcised, or to observe the other legal ceremonies.

[I-II.q.103.a.4.co] All ceremonies are professions of faith, in which the interior worship of God consists. Now man can make profession of his inward faith, by deeds as well as by words: and in either profession, if he make a false declaration, he sins mortally. Now, though our faith in Christ is the same as that of the fathers of old; yet, since they came before Christ, whereas we come after Him, the same faith is expressed in different words, by us and by them. For by them was it said: "Behold a virgin shall conceive and bear a son," where the verbs are in the future tense: whereas we express the same by means of verbs in the past tense, and say that she "conceived and bore." In like manner the ceremonies of the Old Law betokened Christ as having yet to be born and to suffer: whereas our sacraments signify Him as already born and having suffered. Consequently, just as it would be a mortal sin now for anyone, in making a profession of faith, to say that Christ is yet to be born, which the fathers of old said devoutly and truthfully; so too it would be a mortal sin now to observe those ceremonies which the fathers of old fulfilled with devotion and fidelity. Such is the teaching Augustine (Contra Faust. xix, 16), who says: "It is no longer promised that He shall be born, shall suffer and rise again, truths of which their sacraments were a kind of image: but it is declared that He is already born, has suffered and risen again; of which our sacraments, in which Christians share, are the actual representation."

[I-II.q.103.a.4.ad.1] On this point there seems to have been a difference of opinion between Jerome and Augustine. For Jerome (Super Galat. ii, 11, seqq.) distinguished two periods of time. One was the time previous to Christ's Passion, during which the legal ceremonies were neither dead, since they were obligatory, and did expiate in their own fashion; nor deadly, because it was not sinful to observe them. But immediately after Christ's Passion they began to be not only dead, so as no longer to be either effectual or binding; but also deadly, so that whoever observed them was guilty of mortal sin. Hence he maintained that after the Passion the apostles never observed the legal ceremonies in real earnest; but only by a kind of pious pretense, lest, to wit, they should scandalize the Jews and hinder their conversion. This pretense, however, is to be understood, not as though they did not in reality perform those actions, but in the sense that they performed them without the mind to observe the ceremonies of the Law: thus a man might cut away his foreskin for health's sake, not with the intention of observing legal circumcision.

But since it seems unbecoming that the apostles, in order to avoid scandal, should have hidden things pertaining to the truth of life and doctrine, and that they should have made use of pretense, in things pertaining to the salvation of the faithful; therefore Augustine (Epist. lxxxii) more fittingly distinguished three periods of time. One was the time that preceded the Passion of Christ, during which the legal ceremonies were neither deadly nor dead: another period was after the publication of the Gospel, during which the legal ceremonies are both dead and deadly. The third is a middle period, viz. from the Passion of Christ until the publication of the Gospel, during which the legal ceremonies were dead indeed, because they had neither effect nor binding force; but were not deadly, because it was lawful for the Jewish converts to Christianity to observe them, provided they did not put their trust in them so as to hold them to be necessary unto salvation, as though faith in Christ could not justify without the legal observances. On the other hand, there was no reason why those who were converted from heathendom to Christianity should observe them. Hence Paul circumcised Timothy, who was born of a Jewish mother; but was unwilling to circumcise Titus, who was of heathen nationality.

The reason why the Holy Ghost did not wish the converted Jews to be debarred at once from observing the legal ceremonies, while converted heathens were forbidden to observe the rites of heathendom, was in order to show that there is a difference between these rites. For heathenish ceremonial was rejected as absolutely unlawful, and as prohibited by God for all time; whereas the legal ceremonial ceased as being fulfilled through Christ's Passion, being instituted by God as a figure of Christ.

[I-II.q.103.a.4.ad.2] According to Jerome, Peter withdrew himself from the Gentiles by pretense, in order to avoid giving scandal to the Jews, of whom he was the Apostle. Hence he did not sin at all in acting thus. On the other hand, Paul in like manner made a pretense of blaming him, in order to avoid scandalizing the Gentiles, whose Apostle he was. But Augustine disapproves of this solution: because in the canonical Scripture (viz. Galatians 2:11), wherein we must not hold anything to be false, Paul says that Peter "was to be blamed." Consequently it is true that Peter was at fault: and Paul blamed him in very truth and not with pretense. Peter, however, did not sin, by observing the legal ceremonial for the time being; because this was lawful for him who was a converted Jew. But he did sin by excessive minuteness in the observance of the legal rites lest he should scandalize the Jews, the result being that he gave scandal to the Gentiles.

[I-II.q.103.a.4.ad.3] Some have held that this prohibition of the apostles is not to be taken literally, but spiritually: namely, that the prohibition of blood signifies the prohibition of murder; the prohibition of things strangled, that of violence and rapine; the prohibition of things offered to idols, that of idolatry; while fornication is forbidden as being evil in itself: which opinion they gathered from certain glosses, which expound these prohibitions in a mystical sense. Since, however, murder and rapine were held to be unlawful even by the Gentiles, there would have been no need to give this special commandment to those who were converted to Christ from heathendom. Hence others maintain that those foods were forbidden literally, not to prevent the observance of legal ceremonies, but in order to prevent gluttony. Thus Jerome says on Ezekiel 44:31 ("The priest shall not eat of anything that is dead"): "He condemns those priests who from gluttony did not keep these precepts."

But since certain foods are more delicate than these and more conducive to gluttony, there seems no reason why these should have been forbidden more than the others.

We must therefore follow the third opinion, and hold that these foods were forbidden literally, not with the purpose of enforcing compliance with the legal ceremonies, but in order to further the union of Gentiles and Jews living side by side. Because blood and things strangled were loathsome to the Jews by ancient custom; while the Jews might have suspected the Gentiles of relapse into idolatry if the latter had partaken of things offered to idols. Hence these things were prohibited for the time being, during which the Gentiles and Jews were to become united together. But as time went on, with the lapse of the cause, the effect lapsed also, when the truth of the Gospel teaching was divulged, wherein Our Lord taught that "not that which entereth into the mouth defileth a man" (Matthew 15:11); and that "nothing is to be rejected that is received with thanksgiving" (1 Timothy 4:4). With regard to fornication a special prohibition was made, because the Gentiles did not hold it to be sinful.
