Matthew 23:3

But if the Scribes and Pharisees who sit in Moses' seat are the teachers of the Jews, teaching the commandments of the Law according to the letter, how is this that the Lord bids us do after all things which they say; but the Apostles in the Acts forbid the believers to do according to the letter of the Law. (Acts 15:19.) These indeed taught after the letter, not understanding the Law spiritually. Whatsoever they say to us out of the Law, with understanding of its sense, that we do and keep, not doing after their works, for they do not what the law enjoins, nor perceive the veil that is upon the letter of the Law. Or by all we are not to understand every thing in the Law, many things for example relating to the sacrifices, and the like, but such as concern our conduct. But why did He command this not of the Law of grace, but of the doctrine of Moses? Because truly it was not the time to publish the commandments of the New Law before the season of His passion. I think also that He had herein something further in view. He was about to bring many things against the Scribes and Pharisees in His discourse following, wherefore that vain men might not think that He coveted their place of authority, or spoke thus out of enmity to them, he first puts away from Himself this suspicion, and then begins to reprove them, that the people might not fall into their faults; and that, because they ought to hear them, they should not think that therefore they ought to imitate them in their works, He adds, But do ye not after their works. What can be more pitiable than such a teacher, whose life to imitate is ruin, to refuse to follow is salvation for his disciples?

(Hom. lxxii.) But that none should say, For this cause am I slack to practise, because my instructor is evil, He removes every such plea, saying, All therefore whatsoever they say unto you, that observe and do, for they speak not their own, but God's, which things He taught through Moses in the Law. And look with how great honour He speaks of Moses, showing again what harmony there is with the Old Testament.

Look with what He begins His reproof of them, For they say, and do not. Every one who transgresses the Law is deserving of blame, but especially he who has the post of instruction. And this for a threefold cause; first, because he is a transgressor; secondly, because when he ought to set others right, be himself halts; thirdly, because, being in the rank of a teacher, his influence is more corrupting.

But as gold is picked out of the dross, and the dross is left, so hearers may take doctrine and leave practice, for good doctrine oft comes from an evil man. But as Priests judge it better to teach the bad for the sake of the good, rather than to neglect the good for the sake of the bad; so also let those who are set under them pay respect to the bad Priests for the sake of the good, that the good may not be despised because of the bad; for it is better to give the bad what is not their due, rather than to defraud the good of what is justly theirs.

"Then spake Jesus to the multitudes and to His disciples, saying, The Scribes and the Pharisees sit in Moses' seat: all therefore whatsoever they bid you do, that do; but do not after their works." Then. When? When He had said these things, when He had stopped their mouths; when He had brought them that they should no more dare to tempt Him; when He had shown their state incurable. And since He had made mention of "the Lord" and "my Lord," He recurs again to the law. And yet the law said nothing of this kind, but, "The Lord thy God is one Lord." But Scripture calls the whole Old Testament the law. But these things He saith, showing by all thinks His full agreement with Him that begat Him. For if He were opposed, He would have said the opposite about the law; but now He commands so great reverence to be shown towards it, that, even when they that teach it are depraved, He charges them to hold to it. But here He is discoursing about their life and morals, since this was chiefly the cause of their unbelief, their depraved life, and the love of glory. To amend therefore His hearers; that which in the first place most contributes to salvation, not to despise our teachers, neither to rise up against our priests, this doth He command with superabundant earnestness. But He does not only command it, but also Himself doth it. For though they were depraved, He doth not depose them from their dignity; to them rendering their condemnation heavier, and to His disciples leaving no cloke for disobedience. I mean, that lest any one should say, that because my teacher is bad, therefore am I become more remiss, He takes away even this pretext. So much at any rate did He establish their authority, although they were wicked men, as even after so heavy an accusation to say, "All whatsoever they command you to do, do." For they speak not their own words, but God's, what He appointed for laws by Moses. And mark how much honor He showed towards Moses, again showing His agreement with the Old Testament; since indeed even by this doth He make them objects of reverence. "For they sit," He saith, "on Moses' seat." For because He was not able to make them out worthy of credit by their life, He doth it from the grounds that were open to Him, from their seat, and their succession from him. But when thou hearest all, do not understand all the law, as, for instance, the ordinances about meats, those about sacrifices, and the like for how was He to say so of these things, which He had taken away beforehand? but He meant all things that correct the moral principle, and amend the disposition, and agree with the laws of the New Testament, and suffer them not any more to be under the yoke of the law. Wherefore then doth He give these things divine authority, not from the law of grace, but from Moses? Because it was not yet time, before the crucifixion, for these things to be plainly declared. But to me He seems, in addition to what has been said, to be providing for another object, in saying these things. For since He was on the point of accusing them, that He might not seem in the sight of the foolish to set His heart on this authority of theirs, or for enmity to be doing these things, first He removed this thought, and having set himself clear from suspicion, then begins His accusation. And for what intent doth He convict them, and run out into a long discourse against them? To set the multitude on their guard, so that they might not fall into the same sins. For neither is dissuading like pointing out those that have offended; much as recommending what is right, is not like bringing forward those that have done well. For this cause also He is beforehand in saying, "Do not after their works." For, lest they should suppose, because of their listening to them, they ought also to imitate them, He uses this means of correction, and makes what seems to be their dignity a charge against them. For what can be more wretched than a teacher, when the preservation of his dis
