6. Commentary on Galatians — Martin Luther
Martin Luther's writing in the 500 years since the Reformation has influenced far reaching spheres across Christianity, religion, democracies, economies and societies. And as he studied Galatians, as well as Romans, Hebrews, and Psalms, he developed the doctrine of justification by faith alone, by God's grace. This book, his commentary on Galatians, has become a classic masterwork.
