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 [marg. note: Acts 15:19] forbid the believers to do according to the letter of the Law. 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?
