of faith in Christ for salvation. The opening of this commentary sets the stage for Luther's exploration of the key themes in Paul's letter. Luther begins by explaining the context behind Paul's writing, detailing the influence of Judaizers who challenged the Galatian believers with a distorted version of the Gospel that emphasized adherence to the Law. He introduces the importance of Paul's authority as an apostle, reiterating that his teachings come by revelation from Jesus Christ. Luther's tone is passionate and urgent, as he emphasizes the perils of straying from the foundational beliefs of Christianity. The opening thus establishes a framework for understanding the nature of faith, grace, and the impact of the Gospel on both individual believers and the church as a whole.
