Galatians 1:6

"I marvel that ye 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 hath 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 ye 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 ye suffer so many things in vain? if it be indeed in vain." "Ye are removing;" he says not, "ye 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 ye 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 hath 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 Thine, and Thine are Mine." He says not "ye 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."
