Galatians

Summary of the Book of Galatians

Written: c. AD 48–55

Galatians is the only letter Paul opens without a word of thanksgiving. Instead: "I marvel that you are so quickly deserting him who called you." Agitators had followed Paul into the Galatian churches teaching that Gentile believers must be circumcised and keep the law of Moses to belong fully to God's people. For Paul this was not a secondary dispute but "a different gospel, which is not another" — and the letter, possibly his earliest, is his most combative.

He argues in three movements. First, autobiography (1–2): his gospel came by revelation of Jesus Christ, not from human authority; the Jerusalem apostles added nothing to it; and when Cephas (Peter) withdrew from eating with Gentiles at Antioch, Paul opposed him to his face — because "a man is not justified by the works of the law but through faith in Jesus Christ." Second, Scripture (3–4): Abraham believed God before circumcision existed; the law, arriving 430 years after the promise, served as a tutor until Christ came; in him believers are sons and heirs who cry "Abba, Father" — a point sealed by the contrast of Hagar and Sarah, slavery and freedom. Third, life (5–6): Christ has set believers free — a freedom expressed not in license but in love, walking by the Spirit, whose fruit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

Taking the pen himself in large letters, Paul closes with the letter's verdict: circumcision and uncircumcision count for nothing; a new creation counts for everything. Galatians has served ever since as the church's charter of justification by faith and freedom in the Spirit.

Written to defend justification by faith apart from works of the law and to call believers back to freedom in the Spirit.
