Before whose eyes Jesus Christ….crucified among you.[1] The common exposition is, that St. Paul had before described and set before them Christ crucified. Others, that it had been clearly foretold by the prophets that Christ was crucified for them. (Witham)
The third reason or argument taken of those gifts of the holy Ghost, wherewith they were endued from heaven after they had heard and believed the Gospel by Paul’s ministry: which seeing they were so evident to all men’s eyes, that they were as it were lively images, wherein they might behold the truth of the doctrine of the Gospel, no less than if they had beheld with their eyes Christ himself crucified, in whose only death they ought to have their trust, he marvelleth how it could be that they could be so bewitched by the false apostles. Christ was laid before you, so notably and so plainly, that you had his lively image as it were represented before your eyes, as if he had been crucified before you.
Verses 1-5 Several things made the folly of the Galatian Christians worse. They had the doctrine of the cross preached, and the Lord's supper administered among them, in both which Christ crucified, and the nature of his sufferings, had been fully and clearly set forth. Had they been made partakers of the Holy Spirit, by the ministration of the law, or on account of any works done by them in obedience thereto? Was it not by their hearing and embracing the doctrine of faith in Christ alone for justification? Which of these had God owned with tokens of his favour and acceptance? It was not by the first, but the last. And those must be very unwise, who suffer themselves to be turned away from the ministry and doctrine which have been blessed to their spiritual advantage. Alas, that men should turn from the all-important doctrine of Christ crucified, to listen to useless distinctions, mere moral preaching, or wild fancies! The god of this world, by various men and means, has blinded men's eyes, lest they should learn to trust in a crucified Saviour. We may boldly demand where the fruits of the Holy Spirit are most evidently brought forth? whether among those who preach justification by the works of the law, or those who preach the doctrine of faith? Assuredly among the latter.
He reproves them, and the reproof is very close and warm: he calls them foolish Galatians, v. 1. Though as Christians they were Wisdom's children, yet as corrupt Christians they were foolish children. Yea, he asks, Who hath bewitched you? whereby he represents them as enchanted by the arts and snares of their seducing teachers, and so far deluded as to act very unlike themselves. That wherein their folly and infatuation appeared was that they did not obey the truth; that is, they did not adhere to the gospel way of justification, wherein they had been taught, and which they had professed to embrace. Note, It is not enough to know the truth, and to say we believe it, but we must obey it too; we must heartily submit to it, and stedfastly abide by it. Note, also, Those are spiritually bewitched who, when the truth as it is in Jesus is plainly set before them, will not thus obey it. Several things proved and aggravated the folly of these Christians.
Did you receive the Spirit by the works of the law? As if he said, you esteem it a great favour to have received those spiritual gifts of working miracles, &c. When you were made Christians, had you these favours by the works of the law, or was it not by the hearing of faith, and by the faith of Christ, that you had such extraordinary graces? and when you have begun thus happily by the spirit of Christ and his spiritual gifts, are you for finishing and thinking to make yourselves more perfect by the exterior works of the law, the circumcision of the flesh, and such like ceremonies? (Witham)
2. He appeals to the experiences they had had of the working of the Spirit upon their souls (v. 2); he puts them in mind that, upon their becoming Christians, they had received the Spirit, that many of them at least had been made partakers not only of the sanctifying influences, but of the miraculous gifts, of the Holy Spirit, which were eminent proofs of the truth of the Christian religion and the several doctrines of it, and especially of this, that justification is by Christ only, and not by the works of the law, which was one of the peculiar and fundamental principles of it. To convince them of the folly of their departing from this doctrine, he desires to know how they came by these gifts and graces: Was it by the works of the law, that is, the preaching of the necessity of these in order to justification? This they could not say, for that doctrine had not then been preached to them, nor had they, as Gentiles, any pretence to justification in that way. Or was it by the hearing of faith, that is, the preaching of the doctrine of faith in Christ as the only way of justification? This, if they would say the truth, they were obliged to own, and therefore must be very unreasonable if they should reject a doctrine of the good effects of which they had had such experience. Note, (1.) It is usually by the ministry of the gospel that the Spirit is communicated to persons. And, (2.) Those are very unwise who suffer themselves to be turned away from the ministry and doctrine which have been blessed to their spiritual advantage.
3. He calls upon them to consider their past and present conduct, and thence to judge whether they were not acting very weakly and unreasonably (v. 3, 4): he tells them that they had begun in the Spirit, but now were seeking to be made perfect by the flesh; they had embraced the doctrine of the gospel, by means of which they had received the Spirit, and wherein only the true way of justification is revealed. And thus they had begun well; but now they were turning to the law, and expected to be advanced to higher degrees of perfection by adding the observance of it to faith in Christ, in order to their justification, which could end in nothing but their shame and disappointment: for this, instead of being an improvement upon the gospel, was really a perversion of it; and, while they sought to be justified in this way, they were so far from being more perfect Christians that they were more in danger of becoming no Christians at all; hereby they were pulling down with one hand what they had built with the other, and undoing what they had hitherto done in Christianity. Yea, he further puts them in mind that they had not only embraced the Christian doctrine, but suffered for it too; and therefore their folly would be the more aggravated, if now they should desert it: for in this case all that they had suffered would be in vain—it would appear that they had been foolish in suffering for what they now deserted, and their sufferings would be altogether in vain, and of no advantage to them. Note, (1.) It is the folly of apostates that they lose the benefit of all they have done in religion, or suffered for it. And, (2.) It is very sad for any to live in an age of services and sufferings, of sabbaths, sermons, and sacraments, in vain; in this case former righteousness shall not be mentioned.
If yet in vain: i.e. I have still good hopes, that what you have already suffered by persecutions and self-denials, since your conversion, will not be in vain; as they would be, if you sought to be justified by the works and ceremonies of the law of Moses, and not by the faith and law of Christ, by which only you can be truly sanctified. (Witham) — St. Jerome, St. Augustine, and others, suppose that the power of working miracles still remained in the Galatians, notwithstanding what had passed; but St. Chrysostom and several others, explain it of a power they had formerly possessed.
