The Galatians had not been tricked by a subtle philosophy. Paul names it plainly: they were bewitched. The verb carries the weight of a spell cast over eyes that had once seen Jesus Christ crucified, openly, as though a placard had been raised before them. That public spectacle of the cross had been enough. Now something else had crowded the vision—a demand for the works of the law, as though the Spirit they had received by hearing with faith needed a supplement of circumcision and dietary boundaries.
Paul does not begin with a defense of his apostleship. He begins with a single question that cuts through every argument: Did you receive the Spirit by the works of the law, or by the hearing of faith? The answer is embedded in their own experience. They had seen miracles. They had suffered for the gospel. None of that had come because they had first kept the law. It had come because they believed the message preached to them.
The apostle reaches back past Sinai to Abraham. The patriarch was not justified by circumcision—that sign came later. He was not justified by the law—the law did not exist for another four hundred and thirty years. Abraham believed God, and it was counted to him as righteousness. That single sentence from Genesis becomes the hinge of Paul’s argument. The true children of Abraham are not those who share his blood or his mark, but those who share his faith.
Paul then presses the logic further. The law itself pronounces a curse on anyone who does not continue in all things written in the book of the law. No one has kept all things. Therefore everyone under the law stands under that curse. Christ absorbed that curse by becoming a curse for us, hung on a tree. The purpose was not to abolish the promise but to release the blessing of Abraham to the Gentiles, so that the promise of the Spirit might be received through faith.
The apostle makes a careful legal argument about covenants. Once a human covenant is confirmed, no one annuls it or adds to it. The covenant with Abraham was confirmed by God himself. The law, which came centuries later, cannot override that earlier promise. If the inheritance came through the law, it would no longer be by promise. But God gave it to Abraham by promise, and a promise does not depend on human performance.
This raises an obvious question: if the law cannot save, why was it given? Paul answers directly. It was added because of transgressions, until the seed should come to whom the promise had been made. The law was not a path to life; it was a temporary custody, a tutor appointed to guard a minor until the heir came of age. The law exposed sin, restrained it, and pointed forward to the one who would fulfill what the law could not.
The tutor metaphor is sharp. A tutor in the ancient world was not a teacher in the modern sense. He was a slave who escorted a child to school, disciplined him, and kept him from harm. The child was under authority, but the authority was never meant to be permanent. When the heir came of age, the tutor’s role ended. So with the law. It had its season. But now that faith has come, believers are no longer under a tutor.
Paul draws the conclusion with a series of declarations that erase every human division. All who are baptized into Christ have put on Christ. There is neither Jew nor Greek, slave nor free, male nor female. The distinctions that the law had guarded—circumcised and uncircumcised, clean and unclean, priest and layperson—are swallowed up in the single identity of being in Christ. All are one man in Christ Jesus.
The final sentence returns to Abraham. If you belong to Christ, you are Abraham’s seed, heirs according to the promise. The inheritance does not come through the law. It does not come through ethnic descent. It comes through being joined to the one seed, Christ. The Galatians had begun in the Spirit. Paul’s letter is a call to stop trying to perfect in the flesh what was never begun by the flesh.
