Galatians 2:18

For if I build again the things which I destroyed,.... Which must be understood not of good things, for formerly he destroyed the faith of the Gospel, at least as much as in him lay, and now he built

For if I build again the things which I destroyed, I make myself a transgressor.

By the things which he destroyed, some understand the state of sin; and from hence conclude the mutability of a state of justification: but there is no need of that, it may as well be understood of a constant course and voluntary acts of sin. If I teach a doctrine that shall encourage a sinful life, or if I should live in a course of sin, these are the things which I, as a minister of Christ, have in my preaching and doctrine destroyed, teaching you, that not only the guilt of your sins was removed upon your justification by Christ, but the dominion of sin also destroyed: and they are things which justification destroyeth; God never saying to any soul: Thy sins are forgiven thee, without adding, sin no more. So as, if a justified state would admit of a going on in a settled course of sin, it would build what it destroyed. I make myself a transgressor; now should I, or any one, do any such thing, we should thereby make ourselves great transgressors. So as the apostle’ s argument here seemeth to be the same with that, : How shall we, that are dead to sin, live any longer therein? He strives at the same thing here, viz. to prove that the doctrine of justification by faith in Christ, could not give a liberty to any to sin, because it shows persons made partakers of that grace, that they are freed, not only from the guilt, but also from the power and dominion of sin, so as that none can from it receive any comfort as to the former, nor find the latter wrought in them.

(18) But Christ is not a minister of sin. The thought is not to be tolerated. For, on the contrary, the sin is seen, not in leaving the Law for Christ, but in going back from Christ to the Law. The sin is seen doubly: for on one theory—the theory that the Law is valid—it was wrong to give it up; while on the other theory, that Christianity has taken its place, it is still more wrong to restore the fabric that has once been broken down. For.—The connection is with the words immediately preceding: “God forbid that Christ should be the minister of sin.” The idea is absurd as well as profane. For, instead of the Pauline Christian (who follows Christianity to its logical results) being the sinner, it is really the Judaising Christian who stands self-condemned—i.e., in returning to what he has forsaken. If I build again.—The first person is used out of delicate consideration for his opponents. The Apostle is going to put a supposed case, which really represents what they were doing; but in order to soften the directness of the reference he takes it, as it were, upon himself. St. Paul is fond of metaphors taken from building. Comp. Romans 15:20 (building upon another man’s foundation), 1 Corinthians 3:10-14 (Christ the foundation), Ephesians 2:20-22 (the Church built on the foundation of Apostles and prophets), and the words “edify” and “edification” wherever they occur. The idea of “pulling down” or “destroying” is also frequently met with. So in Romans 14:20 (“for meat destroy not the work of God,” the same word as here used, in opposition to “edify,” immediately before); 2 Corinthians 5:1 (“if our earthly house of this tabernacle were dissolved”—pulled down or destroyed); 2 Corinthians 10:4 (“mighty to the pulling down of strongholds”)—a different word in the Greek, but similar in meaning. We may compare with the whole verse the well-known saying, “Burn what you have adored, and adore what you have burned.” The things which I destroyed—i.e., the Mosaic law, the binding obligation of which had been done away in Christ. Make myself.—Show, or prove myself to be: the same word as that translated “commend” in Romans 3:5; Romans 5:8. A transgressor.—Hitherto the Apostle had kept up a sort of studied ambiguity in his use of the words “sin,” “sinner.” The Jews called the Gentiles “sinners,” simply from the fact of their being Gentiles. The Pauline Christian placed himself on the same footing with the Gentiles, so far as the Law was concerned, and therefore he, too, in the same phraseology, was a sinner. But now the Apostle uses a word that could not be mistaken. A sinner the Christian might be, in the Judaising sense of the word, but the Judaiser himself was the real sinner: it was he who offended against the immutable principles of right and wrong.

Verse 18. For if I build again the things which I destroyed] If I act like a Jew, and enjoin the observance of the law on the Gentiles, which I have repeatedly asserted and proved to be abolished by the death of Christ, then I build up what I destroyed, and thus make myself a transgressor, by not observing the law in that way in which I appear to enjoin the observance of it upon others.

18. The edifice which St Paul had pulled down was not, as some suppose, the Levitical law of meats, or the Mosaic ceremonial law, in themselves considered. It was not, as a rule of life, but as a ground of justification, that he utterly repudiated and swept them away.I make myself] Rather, I prove, I conclude myself to be; nearly = I convict myself.a transgressor] nearly equivalent to ‘sinner’ above, which had primary reference to the Gentiles. Sin is the transgression or violation of the law. If I am now trying to build up again the system of justification by legal obedience, I by that very attempt convict myself of having been a transgressor, when instead of obeying the law, I sought to destroy its obligation.

For if I build again the things which I destroyed - Paul here uses the first person; but he evidently intends it as a general proposition, and means that if anyone does it he becomes a transgressor.

18. And our law-keeping does place Christ in this condition; for if I build again the law-justification, which I destroyed, by rejecting it for Christ, I make myself unjustified—a transgressor.
