Galatians 2:17

Look at the absurd direction into which he leads those who are attached to the Law. If the faith in Christ, he says, is not sufficient to justify, but, once again there is a need to uphold the Law, and if those, having left the Law for Christ, are not justified in doing so, but rather are condemned, then Christ will be found to be the cause of our condemnation, since we left the law on his account in order to run towards the faith. "God forbid," he says. Seeing the absurdity, which this doctrine leads to, he immediately turns away from it by using this aphorism.

After proving by the apostles' manner of life that the works of the Law ought not to be observed, the Apostle raises a question to the contrary. About this he does three things: First, he raises the question; Secondly, he solves it (v. 17): "God …

We sought to obtain justification in Christ, he says, having abandoned the law. How then do you say that it is sinful to abandon the law: for it turns out that Christ led us into such a sin, since for His sake we abandoned everything …

But if while we seek to be justified by Christ, we ourselves are still found sinners - If we continue in sin, will it therefore follow, that Christ is the minister or countenancer of sin?

But if while we seek to be justified by Christ,.... As they did, and not only sought for, but obtained what they sought for, because they sought for it at the hands of Christ, and not as it were by works, but by faith, even a justifying righteousness in him.

If, while we seek justification by Christ alone, and teach others to do so, we ourselves are found giving countenance or indulgence to sin, or rather are accounted sinners of the Gentiles, and such as it is not fit to have communion with, unless we also observe the law of Moses, is Christ the minister of sin?

But if, while we seek to be justified by Christ - The connection here is not very clear, and the sense of the verse is somewhat obscure. Rosenmuller supposes that this is an objection of a Jew, supposing that where the Law of Moses is not observed there is no rule of life, and that therefore there must be sin; and that since the doctrine of justification by faith taught that there was no necessity of obeying the ceremonial law of Moses, therefore Christ, who had introduced that system, must be regarded as the author and encourager of sin.

The whole sin lies, not with Christ, but with him who would necessitate such a blasphemous inference. But his false theory, though "seeking" from Christ, we have not "found" salvation (in contradiction to Christ's own words, Mt 7:7), but "have been ourselves also (like the Gentiles) found" to be "sinners," by having entered into communion with Gentiles (Ga 2:12).

But if while we seek to be justified - If, while we acknowledge that we must be justified by faith in Christ, we ourselves are found sinners, enjoining the necessity of observing the rites and ceremonies of the law, which never could and never can justify, and yet, by submitting to circumcision, we lay ourselves under the necessity of fulfilling the law, which is impossible, we thus constitute ourselves sinners; is, therefore, Christ the minister of sin? Christ, who has taught us to renounce the law, and expect justification through his death? God forbid! that we should either act so, or think so.
