Supposing these to be Christ’s genuine words, we should enquire what was His motive for speaking thus, whether to soften the blind hostility of the Jews, who when they saw their holy things trodden under foot by Him, would not have so much as given Him a hearing; or whether He really said them to instruct us, who of the Gentiles should believe, to submit to the yoke of the Law. If this last were not His design, then the first must have been; nor was there any deceit or fraud in such purpose.
For of laws there be three sorts. The first that of the Hebrews, called the “law of sin and death,” [Rom 8:2] by Paul; the second that of the Gentiles, which he calls the law of nature, saying, “By nature the Gentiles do the deeds of the law;” [Rom 2:14] the third, the law of truth, which he means, “The law of the Spirit of life.” Also there are Prophets some of the Jews, such as are well known; others of the Gentiles as Paul speaks, “A prophet of their own hath said;” [Tit 1:12] and others of the truth of whom Jesus speaks, “I send unto you wise men and prophets.” [Matt 23:34]
Now had Jesus in the following part of this Sermon brought forward any of the Hebrew observances to shew how he had fulfilled them, no one would have doubted that it was of the Jewish Law and Prophets that He was now speaking; but when He brings forward in this way only those more ancient precepts, “Thou shalt not kill, Thou shalt not commit adultery,” which were promulged of old to Enoch, Seth, and the other righteous men, who does not see that He is here speaking of the Law and Prophets of truth? Wherever He has occasion to speak of any thing merely Jewish, He plucks it up by the very roots, giving precepts directly the contrary; for example, in the case of that precept, “An eye for an eye, a tooth for a tooth.”
Augustine; Which was the Law and which the Prophets, that Christ came “not to subvert but to fulfil,” is manifest, to wit, the Law given by Moses. And the distinction which Faustus draw between the precepts of the righteous men before Moses, and the Mosaic Law, affirming that Christ fulfilled that one but annulled the other, is not so. We affirm that the Law of Moses was both well suited to its temporary purpose, and was not now subverted, but fulfilled by Christ, as will be seen in each particular. This was not understood by those who continued in such obstinate error, that they compelled the Gentiles to Judaize - those heretics, I mean, who were called Nazarenes.
