Hi Lisa; I'm a dyed in the wool RC and from what I can gather we're simply goy Jews in the sense that Jesus came to fulfil the promises of God in the old Testament. I respect and love our roots in Judaism and frankly see the whole debate on that as somewhat of a yawn. Already covered in some old books I read.Christians believe he did.
Jews believe that was not his intent, and the one who did it was Paul.
I answer that, Without any doubt, the Old Law was good. For just as a doctrine is shown to be good by the fact that it accords with right reason, so is a law proved to be good if it accords with reason. Now the Old Law was in accordance with reason. Because it repressed concupiscence which is in conflict with reason, as evidenced by the commandment, "Thou shalt not covet thy neighbor's goods" (Exodus 20:17). Moreover the same law forbade all kinds of sin; and these too are contrary to reason. Consequently it is evident that it was a good law. The Apostle argues in the same way (Romans 7): "I am delighted," says he (verse 22), "with the law of God, according to the inward man": and again (verse 16): "I consent to the law, that is good."
But it must be noted that the good has various degrees, as Dionysius states (Div. Nom. iv): for there is a perfect good, and an imperfect good. In things ordained to an end, there is perfect goodness when a thing is such that it is sufficient in itself to conduce to the end: while there is imperfect goodness when a thing is of some assistance in attaining the end, but is not sufficient for the realization thereof. Thus a medicine is perfectly good, if it gives health to a man; but it is imperfect, if it helps to cure him, without being able to bring him back to health. Again it must be observed that the end of human law is different from the end of Divine law. For the end of human law is the temporal tranquillity of the state, which end law effects by directing external actions, as regards those evils which might disturb the peaceful condition of the state. On the other hand, the end of the Divine law is to bring man to that end which is everlasting happiness; which end is hindered by any sin, not only of external, but also of internal action. Consequently that which suffices for the perfection of human law, viz. the prohibition and punishment of sin, does not suffice for the perfection of the Divine law: but it is requisite that it should make man altogether fit to partake of everlasting happiness. Now this cannot be done save by the grace of the Holy Ghost, whereby "charity" which fulfilleth the law . . . "is spread abroad in our hearts" (Romans 5:5): since "the grace of God is life everlasting" (Romans 6:23). But the Old Law could not confer this grace, for this was reserved to Christ; because, as it is written (John 1:17), the law was given "by Moses, grace and truth came by Jesus Christ." Consequently the Old Law was good indeed, but imperfect, according to Hebrews 7:19: "The law brought nothing to perfection."
I answer that, The Old Law was given by the good God, Who is the Father of Our Lord Jesus Christ. For the Old Law ordained men to Christ in two ways. First by bearing witness to Christ; wherefore He Himself says (Luke 24:44): "All things must needs be fulfilled, which are written in the law . . . and in the prophets, and in the psalms, concerning Me": and (John 5:46): "If you did believe Moses, you would perhaps believe Me also; for he wrote of Me." Secondly, as a kind of disposition, since by withdrawing men from idolatrous worship, it enclosed [concludebat] them in the worship of one God, by Whom the human race was to be saved through Christ. Wherefore the Apostle says (Galatians 3:23): "Before the faith came, we were kept under the law shut up [conclusi], unto that faith which was to be revealed." Now it is evident that the same thing it is, which gives a disposition to the end, and which brings to the end; and when I say "the same," I mean that it does so either by itself or through its subjects. For the devil would not make a law whereby men would be led to Christ, Who was to cast him out, according to Matthew 12:26: "If Satan cast out Satan, his kingdom is divided" [Vulgate: 'he is divided against himself']. Therefore the Old Law was given by the same God, from Whom came salvation to man, through the grace of Christ.
I answer that, It might be assigned as a reason for the Law being given to the Jews rather than to other peoples, that the Jewish people alone remained faithful to the worship of one God, while the others turned away to idolatry; wherefore the latter were unworthy to receive the Law, lest a holy thing should be given to dogs.
But this reason does not seem fitting: because that people turned to idolatry, even after the Law had been made, which was more grievous, as is clear from Exodus 32 and from Amos 5:25-26: "Did you offer victims and sacrifices to Me in the desert for forty years, O house of Israel? But you carried a tabernacle for your Moloch, and the image of your idols, the star of your god, which you made to yourselves." Moreover it is stated expressly (Deuteronomy 9:6): "Know therefore that the Lord thy God giveth thee not this excellent land in possession for thy justices, for thou art a very stiff-necked people": but the real reason is given in the preceding verse: "That the Lord might accomplish His word, which He promised by oath to thy fathers Abraham, Isaac, and Jacob."
What this promise was is shown by the Apostle, who says (Galatians 3:16) that "to Abraham were the promises made and to his seed. He saith not, 'And to his seeds,' as of many: but as of one, 'And to thy seed,' which is Christ." And so God vouchsafed both the Law and other special boons to that people, on account of the promised made to their fathers that Christ should be born of them. For it was fitting that the people, of whom Christ was to be born, should be signalized by a special sanctification, according to the words of Leviticus 19:2: "Be ye holy, because I . . . am holy." Nor again was it on account of the merit of Abraham himself that this promise was made to him, viz. that Christ should be born of his seed: but of gratuitous election and vocation. Hence it is written (Isaiah 41:2): "Who hath raised up the just one form the east, hath called him to follow him?"
It is therefore evident that it was merely from gratuitous election that the patriarchs received the promise, and that the people sprung from them received the law; according to Deuteronomy 4:36-37: "Ye did [Vulgate: 'Thou didst'] hear His words out of the midst of the fire, because He loved thy fathers, and chose their seed after them." And if again it asked why He chose this people, and not another, that Christ might be born thereof; a fitting answer is given by Augustine (Tract. super Joan. xxvi): "Why He draweth one and draweth not another, seek not thou to judge, if thou wish not to err."
SUMMA THEOLOGIAE: The old law (Prima Secundae Partis, Q. 98)
Was the Old Law good? Was it from God? Did it come from Him through the angels? Was it given to all? Was it binding on all? Was it given at a suitable time?
Some really good stuff in that.
