“Why then,” they say, “does Paul call the present life evil?” In calling the present world [age] evil, he has accommodated himself to our usage, who are wont to say, “I have had a bad day,” thereby complaining not of the time itself, but of actions or circumstances. And so Paul in complaining of evil principles of action has used these customary forms of speech; and he shows that Christ has both delivered us from our offenses, and secured us for the future. The first he has declared in the words, “Who gave Himself for our sins;” and by adding, “that He might deliver us out of this present evil world,” he has pronounced our future safety. For neither of these did the Law avail, but grace was sufficient for both.
Ver. 4. “According to the will of our God and Father.”
Since they were terrified by their notion that by deserting that old Law and adhering to the new, they should disobey God, who gave the Law, he corrects their error, and says, that this seemed good to the Father also: and not simply “the Father,” but “our Father,” which he does in order to affect them by showing that Christ has made His Father our Father.
Ver. 5. “To whom be the glory for ever and ever. Amen.”
This too is new and unusual, for we never find the word, “Amen” placed at the beginning of an Epistle, but a good way on; here, however he has it in his beginning, to show that what he had already said contained a sufficient charge against the Galatians, and that his argument was complete, for a manifest offense does not require an elaborate crimination. Having spoken of the Cross, and Resurrection, of redemption from sin and security for the future, of the purpose of the Father, and the will of the Son, of grace and peace and His whole gift, he concludes with an ascription of praise.
Another reason for it is the exceeding astonishment into which he was thrown by the magnitude of the gift, the superabundance of the grace, the consideration who we were, and what God had wrought, and that at once and in a single moment of time. Unable to express this in words, he breaks out into a doxology, sending up for the whole world an eulogium, not indeed worthy of the subject, but such as was possible to him. Hence too he proceeds to use more vehement language; as if greatly kindled by a sense of the Divine benefits, for having said, “To whom be the glory for ever and ever, Amen,” he commences with a more severe reproof.
Ver. 6. “I marvel that you are so quickly removing from Him that called you in the grace of Christ, unto a different Gospel.”
Like the Jews who persecuted Christ, they imagined their observance of the Law was acceptable to the Father, and he therefore shows that in doing this they displeased not only Christ, but the Father also, for that they fell away thereby not from Christ only, but from the Father also. As the old covenant was given not by the Father only, but also by the Son, so the covenant of grace proceeded from the Father as well as the Son, and Their every act is common: “All things whatsoever the Father has are Mine.” By saying that they had fallen off from the Father, he brings a twofold charge against them, of an apostasy, and of an immediate apostasy. The opposite extreme a late apostasy, is also blameworthy, but he who falls away at the first onset, and in the very skirmishing, displays an example of the most extreme cowardice, of which very thing he accuses them also saying: “How is this that your seducers need not even time for their designs, but the first approaches suffice for your overthrow and capture? And what excuse can you have? If this is a crime among friends, and he who deserts old and useful associates is to be condemned, consider what punishment he is obnoxious to who revolts from God that called him.” He says, “I marvel,” not only by way of reproof, that after such bounty, such a remission of their sins, such overflowing kindness, they had deserted to the yoke of servitude, but also in order to show, that the opinion he had had of them was a favorable and exalted one. For, had he ranked them among ordinary and easily deceived persons, he would not have felt surprise. “But since you,” he says, “are of the noble sort and have suffered, much, I do marvel.” Surely this was enough to recover and lead them back to their first expressions. He alludes to it also in the middle of the Epistle, “Did you suffer so many things in vain? If it be indeed in vain.” “You are removing;” he says not, “you are removed,” that is, “I will not believe or suppose that your seduction is complete;” this is the language of one about to recover them, which further on he expresses yet more clearly in the words, “I have confidence to you-ward in the Lord that you will be none otherwise minded.”
“From Him that called you in the grace of Christ.”
The calling is from the Father, but the cause of it is the Son. He it is who has brought about reconciliation and bestowed it as a gift, for we were not saved by works in righteousness: or I should rather say that these blessings proceed from Both; as He says, “Mine are Yours, and Yours are Mine.” He says not “you are removing from the Gospel” but “from God who called you,” a more frightful expression, and more likely to affect them. Their seducers did not act abruptly but gradually, and while they removed them from the faith in fact, left names unchanged. It is the policy of Satan not to set his snares in open view; had they urged them to fall away from Christ, they would have been shunned as deceivers and corrupters, but suffering them so far to continue in the faith, and putting upon their error the name of the Gospel, without fear they undermined the building employing the terms which they used as a sort of curtain to conceal the destroyers themselves. As therefore they gave the name of Gospel to this their imposture, he contends against the very name, and boldly says, “unto a different Gospel,”—
Ver. 7. “Which is not another Gospel.”
And justly, for there is not another. Nevertheless the Marcionites are misled by this phrase, as diseased persons are injured even by healthy food, for they have seized upon it, and exclaim, “So Paul himself has declared there is no other Gospel.” For they do not allow all the Evangelists, but one only, and him mutilated and confused according to their pleasure. Their explanation of the words, “according to my Gospel and the preaching of Jesus Christ,” is sufficiently ridiculous; nevertheless, for the sake of those who are easily seduced, it is necessary to refute it. We assert, therefore, that, although a thousand Gospels were written, if the contents of all were the same, they would still be one, and their unity no wise infringed by the number of writers. So, on the other hand, if there were one writer only, but he were to contradict himself, the unity of the things written would be destroyed. For the oneness of a work depends not on the number of its authors, but on the agreement or contradictoriness of its contents. Whence it is clear that the four Gospels are one Gospel; for, as the four say the same thing, its oneness is preserved by the harmony of the contents, and not impaired by the difference of persons. And Paul is not now speaking of the number but of the discrepancy of the things spoken. With justice might they lay hold of this expression, if the Gospels of Matthew and Luke differed in the signification of their contents, and in their doctrinal accuracy; but as they are one and the same, let them cease being senseless and pretending to be ignorant of these things which are plain to the very children.
Ver. 7. “Only there are some that trouble you, and would pervert the Gospel of Christ.”
That is to say, you will not recognize another Gospel, so long as your mind is sane, so long as your vision remains healthy, and free from distorted and imaginary phantoms. For as the disordered eye mistakes the object presented to it, so does the mind when made turbid by the confusion of evil thoughts. Thus the madman confounds objects; but this insanity is more dangerous than a physical malady, for it works injury not in the regions of sense, but of the mind; it creates confusion not in the organ of bodily vision, but in the eye of the understanding.
