Introduction To Galatians

Galatians is the Apostle Paul's defense of the gospel of justification by faith alone. False teachers had told Gentile believers they must add circumcision and law-keeping to faith in Christ. Paul answers that the gospel is received "in the grace of Christ" (Galatians 1:6, NKJV) and cannot be supplemented. The letter became central to the Reformation; Martin Luther called it his "Katie von Bora," the epistle to which he was wedded for its clarity on grace alone.

In every other letter Paul thanks God for his readers, but here he moves straight to rebuke: "I marvel that you are turning away so soon" (Galatians 1:6, NKJV). The omission is deliberate and pastoral. A corrupted gospel is not a minor error to be eased into gently. Because the gospel itself was under threat, Paul writes with the holy urgency of a shepherd whose flock is being led toward spiritual ruin.

The Judaizers were teachers who insisted that Gentile Christians must be circumcised and keep the Mosaic law to be truly saved. They did not deny Christ outright; they added requirements to Him. Paul calls this "a different gospel, which is not another" (Galatians 1:6–7, NKJV). Their "faith plus works" formula is the perennial error the Reformers confronted, and it is the reason the doctrine of sola fide, faith alone, had to be recovered.

The word translated "accursed" is anathema, meaning devoted to destruction, under God's judgment. Paul declares, "But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed" (Galatians 1:8, NKJV). No messenger, however exalted, may alter the message. The gospel does not depend on the preacher's status but on its fixed content: salvation by grace through faith in Christ alone.

Paul says, "As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed" (Galatians 1:9, NKJV). The repetition is not careless emphasis but solemn confirmation, like a legal verdict pronounced twice. Calvin observed that Paul's vehemence shows how precious the purity of the gospel is. To tamper with it is not scholarship or progress; it is to forfeit the gospel itself.

Grace alone (sola gratia) means salvation originates entirely in God's unmerited favor, not in human merit. Paul reminds the Galatians they were called "in the grace of Christ" (Galatians 1:6, NKJV). The Westminster Confession (11.1) teaches that God justifies sinners not by infusing righteousness or counting their works, but by imputing Christ's obedience and satisfaction to them. Adding human effort does not strengthen grace; it abolishes grace, turning a gift into a wage.

Paul insists he is an apostle "not from men nor through man, but through Jesus Christ and God the Father" (Galatians 1:1, NKJV). His authority is not a human credential the Judaizers could match or revoke. Because his commission came directly from the risen Christ, the gospel he preached is not his opinion but divine revelation. The integrity of the message rests on the divine origin of the messenger's calling.

Saul of Tarsus was a zealous Pharisee who trusted his own law-righteousness and persecuted the church. Christ stopped him, and the former legalist came to rest entirely in Christ's righteousness rather than his own. His life embodies the letter's argument: no amount of law-keeping justifies, but Christ "gave Himself for our sins" (Galatians 1:4, NKJV). The chief defender of grace alone was once its fiercest opponent, saved by the very grace he now proclaims.

Paul writes that Christ "gave Himself for our sins, that He might deliver us from this present evil age, according to the will of our God and Father" (Galatians 1:4, NKJV). Three truths stand together: Christ's death was substitutionary, it was rescuing, and it was according to the Father's will. Salvation is not a human achievement we offer to God but a finished work God accomplished for us, freely given and fully sufficient.

Every generation faces the temptation to add something to Christ, whether ritual, performance, or moral self-improvement, as the ground of acceptance with God. Paul's words confront that instinct directly: the gospel is grace alone, or it is no gospel. R.C. Sproul taught that justification by faith alone is the article on which the church stands or falls. Galatians 1 calls believers back to resting in Christ's finished work, not their own.
