Martin Luther's Commentary on Galatians is a vigorous defense of the core Christian doctrine of justification by faith alone. Writing to combat false teachers who insisted that believers must also keep the Jewish law and ceremonial traditions to be saved, Luther argues passionately that salvation cannot be earned through human effort, moral striving, or religious works.
The author explores the historical context of Paul's letter, emphasizing that the apostle received his Gospel directly through revelation rather than from human authorities. Luther examines the distinction between the law and the gospel, asserting that the law's true purpose is not to justify, but to expose human sinfulness, humble the proud, and drive the sinner toward Christ for mercy.
Throughout the text, Luther unpacks the substitutionary sacrifice of Christ, explaining how Jesus bore the curse of the law in humanity's place. By taking upon himself the sins of the world, Christ achieved victory over sin, death, and the devil, granting his righteousness freely to all who believe. This divine exchange forms the bedrock of true Christian liberty.
Luther warns against the subtle traps of self-righteousness and legalism, whether found in ancient Judaism or medieval monasticism. He demonstrates that any attempt to supplement faith with personal merit effectively nullifies the grace of God and renders Christ's death pointless. The believer is completely free from the demands of the law regarding justification.
Despite this freedom, Luther addresses the practical life of the Christian, explaining that true faith naturally produces good fruits through the inward working of the Holy Spirit. Love, patience, and service flow outward spontaneously from a heart at peace with God. Good works are the result of salvation, never the cause.
The commentary serves as a robust pastoral guide, written with raw intensity and profound biblical insight. Luther aims to comfort sore consciences, rescuing believers from despair and self-reliance. The work culminates in a celebration of the believer's adoption as a child and heir of God through Christ.
