Commentary on the Epistle to the Galatians by Martin Luther is a detailed and passionate theological exposition of Paul’s letter to the Galatians. Written during the Protestant Reformation, Luther uses the epistle to emphasize the doctrine of justification by faith alone, highlighting themes of Christian freedom, grace, and the contrast between the Law and the Gospel. The work also serves as a critique of the Church’s practices at the time, making it a cornerstone of Reformation thought. This commentary is widely regarded as one of Luther’s most influential theological writings.
