St. Paul’s “Epistle to the Galatians” is one of the most important of all Christian writings. The work was treasured by Martin Luther, the 15th century German priest, scholar, and father of the Protestant Reformation. For this reason, Luther delivered lectures on the “Epistle to the Galatians” in 1531 and published those lectures in 1535. The resulting “Commentary on Galatians” by Luther is widely regarded as one of the most important commentaries ever written on Christian faith and love. Deeply personal and at least in part autobiographical, Luther explains why St. Paul’s “Epistle to the Galatians” is so important and meaningful to both him and to the Christian faith. Paul’s “Epistle” and Luther’s “Commentary” have assured countless Christians of the superiority of the Bible over human reason, the perfection of Christ’s sacrifice and atonement through his death, and the essential doctrine of justification through faith alone as the foundation for all Christians. Moving and passionate, Luther expresses the strength and comfort that he has found in this faith. This masterpiece continues to remain as inspiring and important to Christians today in understanding their faith as it has been for the last five hundred years.
