Pope Piux XII, Mystici Corporis Christi, 29-30: the New Testament took the placeof the Old Law which had been abolishedbut on the gibbet of His death Jesus made void the Law with its decrees fastened the handwriting of the Old Testament to the Cross. On the Cross then the Old Law died, soon to be buried and to be a bearer of death, in order to give way to the New Testament of which Christ had chosen the Apostles as qualifed ministers.The Catechism of the Council of Trent: Part III: The Decalogue: With regard to the exposition of this Commandment, the faithful are carefully to be taught how it agrees with, and how it difers from the others, in order that they may understand why we observe and keep holy not Saturday but Sunday. The point of diference is evident. The other Commandments of the Decalogue are precepts of the natural law, obligatory at all times and unalterable. Hence, after the abrogation of the Law of Moses, all the Commandments contained in the two tables are observed by Christians, not indeed because their observance is commanded by Moses, but because they are in conformity with nature which dictates obedience to them.[3]Council of Florence: that the matter pertaining to the law of the Old Testament, of the Mosaic lawalthough they were suited to the divine worship at that time, after our Lords coming had been signifed by them, ceased, and the sacraments of the New Testament began.[4]Pope Urban VIII, Profession of Orthodox Faith, 1642: Similarly, we profess that the legalities of the Old Testament, the ceremonies of the Mosaic Law, the rites, sacrifces, and sacraments have ceased at the coming of Our Lord Jesus Christ; they cannot be observed without sin after the promulgation of the Gospel. The distinction of clean and unclean foods found in the old Law pertains to the ceremonies which have passed away with the rise of the Gospel. The Apostles' prohibition on food ofered to idols, blood, and the meat of strangled animals was suitable at that time to remove cause for disagreement between Jews and Gentiles;but since the reason for this prohibition has ceased to be, the prohibition too has come to an end.Pope Benedict XV, Ex Quo, 63: The second consideration is that although the ceremonial precepts of the old Law have come to an end with the promulgation of the Gospel, and the new Law does not contain any precept which distinguishes between clean and unclean foods, nevertheless the Church of Christ has the powerof renewing the obligation to observe some of the old precepts for just and serious reasons, despite their abrogation by the new Law.[5]The Fathers (representative sample of their consensus):St. John Chrysostom: Yet surely Pauls object everywhere is to annul this Law.And with much reason; for it was through a fear and a horror of this that the Jews obstinately opposed grace (Homily on Romans, 6:12); And so while no one annuls a mans covenant, the covenant of God after four hundred and thirty years isannulled; for if not that covenant but another instead of it bestows what is promised,then is it set aside, which is most unreasonable (Homily on Galatians, Ch 3);St. Augustine: Instead of the grace of the law which has passed away, we have received the grace of the gospel which is abiding; and instead of the shadows and types of the old dispensation, the truth has come by Jesus Christ. Jeremiah also prophesied thus in Gods name: Behold, the days come, says the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah... Observe what the prophet says, not to Gentiles, who had not been partakers in any former covenant, but to the Jewish nation. He who has given them the law by Moses, promises in place of it the New Covenant of the gospel, that they might no longer live in the oldness of the letter, but in the newness of the spirit (Letters, 74, 4);Justin Martyr: Now, law placed against law has abrogated that which is before it, and a covenant which comes after in like manner has put an end to the previous one; and an eternal and fnal law namely, Christ has been given to us, and the covenant is trustworthyHave you not readby Jeremiah, concerning this same new covenant, He thus speaks: Behold, the days come, says the Lord, that I will make a new covenant with the house of Israel and with the house of Judah (Dialogue with Trypho, Ch 11).
