Written by Paul the Apostle
Introduction
Galatians is the shortest fuse Paul ever lit on paper. Written to a cluster of churches in the Roman province of Galatia that Paul had planted on his first missionary journey, the letter responds to a crisis: after Paul had left, a group of Jewish-Christian teachers (the Judaizers, as later tradition called them) had arrived and were convincing the Galatian believers that faith in Christ was not enough — that to be fully included in the people of God, Gentile converts would also need to be circumcised and keep the Mosaic law. The entire gospel Paul had preached to them — justification by faith, Jew and Gentile united in Christ, freedom from the law as the ground of righteousness — was being undone behind his back.
Paul’s response is unlike any other letter he wrote. He skips the customary thanksgiving section entirely, the only Pauline letter that does so, and opens instead with astonishment that they are so quickly deserting the one who called them. The six chapters that follow are structured in three movements of two chapters each. Chapters 1 and 2 establish the independent authority of the gospel Paul preaches, tracing his own history from conversion through his encounters with Peter and the Jerusalem apostles, culminating in the Antioch confrontation where Paul rebuked Peter publicly for withdrawing from Gentile table fellowship under pressure from the circumcision party. Chapters 3 and 4 make the theological argument from Abraham, the law, and the coming of Christ — that the promise preceded the law by 430 years, that the law was a temporary guardian until the promised seed arrived, and that those who are in Christ are now sons and heirs by faith rather than slaves under elementary principles. Chapters 5 and 6 draw the practical conclusions: the freedom Christ purchased is not freedom to sin but freedom to walk by the Spirit, to love one’s neighbor, and to bear the fruit that the Spirit produces in those who belong to him.
“For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery.” — Galatians 5:1
The stakes of the letter go beyond its immediate occasion. Every generation of the church has faced some version of the Galatian temptation — the quiet smuggling of works, rules, or merit-systems back into a gospel that was always and only about grace received through faith in a crucified and risen Lord. Martin Luther, reading this letter in the sixteenth century, recognized it as the Reformation’s charter document. But the letter’s target is not limited to any one historical movement. Wherever the gospel of Christ alone has been supplemented with anything that makes the believer’s standing with God contingent on performance — ritual, legalism, moral self-improvement, hidden credentials of any kind — the letter cuts just as cleanly as it did in AD 49. Paul’s warning is total: a gospel that adds anything to Christ is not a modified gospel. It is a different gospel. And a different gospel, he says plainly, is no gospel at all.
