Galatia was a region in central Asia Minor where Paul planted churches during his missionary journeys. The letter to the Galatians is Paul's most passionate and urgent epistle, written to combat the Judaizers -- false teachers who insisted that Gentile believers must be circumcised and keep the Mosaic law to be saved. Paul's response is the magna carta of Christian liberty: justification is by faith alone in Christ alone, not by works of the law (Galatians 2:16). The letter contains Paul's most forceful defense of the gospel of grace, his autobiographical account of his apostolic calling, the allegory of Sarah and Hagar (Galatians 4:21-31), and the fruit of the Spirit (Galatians 5:22-23). Galatia represents the perennial temptation to add human works to the finished work of Christ -- and Paul's letter represents the definitive answer: "For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery" (Galatians 5:1).
A province of Asia Minor, inhabited by a mixed population of Gauls and Greeks.
GALA'TIA, n. [Gr. Galatia, from Galatai, Gauls.] A province in the central part of Asia Minor, settled by Gauls or Celts, to whose churches Paul addressed his epistle on justification by faith.
• Galatians 2:16 — "Yet we know that a person is not justified by works of the law but through faith in Jesus Christ."
• Galatians 5:1 — "For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery."
• Galatians 5:22-23 — "But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control."
The Galatian error -- adding works to grace -- is the most common heresy in every generation of the church.
The Galatian heresy never dies. Every generation of the church produces teachers who add requirements to the gospel: you must be circumcised, you must keep the Sabbath, you must speak in tongues, you must follow these dietary laws, you must achieve this level of moral performance. The specific additions change; the error remains the same. Paul's response is always the same: if righteousness could come through the law, then Christ died for nothing (Galatians 2:21). Any gospel that adds human works to Christ's finished work is, as Paul says, "a different gospel -- which is really no gospel at all" (Galatians 1:6-7).
• "The Galatian heresy is alive in every church that makes any human work a requirement for salvation beyond faith in Christ alone."
• "Paul told the Galatians that if they accepted circumcision as necessary for salvation, Christ would be of no advantage to them. You cannot add to a finished work."
