Catena Aurea

17. Think not that I am come to destroy the Law, or the Prophets: I am not come to destroy, but to fulfil.

18. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.

19. Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.

GLOSS. (ord.) Having now exhorted His hearers to undergo all things for righteousness’ sake, and also not to hide what they should receive, but to learn more for others’ sake, that they may teach others, He now goes on to tell them what they should teach, as though He had been asked, ‘What is this which you would not have hid, and for which you would have all things endured? Are you about to speak any thing beyond what is written in the Law and the Prophets;’ hence it is He says, Think not that I am come to subvert the Law or the Prophets.

PSEUDO-CHRYSOSTOM. And that for two reasons. First, that by these words He might admonish His disciples, that as He fulfilled the Law, so they should strive to fulfil it. Secondly, because the Jews would falsely accuse them as subverting the Law, therefore he answers the calumny beforehand, but in such a manner as that He should not be thought to come simply to preach the Law as the Prophets had done.

REMIGIUS. He here asserts two things; He denies that He was come to subvert the Law, and affirms that He was come to fulfil it.

AUGUSTINE. (Serm. in Mont. i. 8.) In this last sentence again there is a double sense; to fulfil the Law, either by adding something which it had not, or by doing what it commands.

CHRYSOSTOM. (Hom. xvi.) Christ then fulfilled the Prophets by accomplishing what was therein foretold concerning Himself—and the Law, first, by transgressing none of its precepts; secondly, by justifying by faith, which the Law could not do by the letter.

AUGUSTINE. (cont. Faust. xix. 7. et seq.) And lastly, because even for them who were under grace, it was hard in this mortal life to fulfil that of the Law, Thou shalt not lust, He being made a Priest by the sacrifice of His flesh, obtained for us this indulgence, even in this fulfilling the Law, that where through our infirmity we could not, we should be strengthened through His perfection, of whom as our head we all are members. For so I think must be taken these words, to fulfil the Law, by adding to it, that is, such things as either contribute to the explanation of the old glosses, or to enable to keep them. For the Lord has shewed us that even a wicked motion of the thoughts to the wrong of a brother is to be accounted a kind of murder. The Lord also teaches us, that it is better to keep near to the truth without swearing, than with a true oath to come near to blasphemy.
