In sermons and pamphlets, Luther and his colleagues claimed that salvation came by faith alone and not by works. Although the better-known pamphlets of 1520--To the Christian Nobility of the German Nation Concerning the Improvement of the Christian Estate, The Babylonian Captivity of the Church, and The Freedom of a Christian-- would also appear, Timothy J. Wengert shows how Luther's Treatise on Good Works fulfilled Luther's own prediction that it would be one of the clearest and most accessible introductions to Luther's reforming work and theology. Luther's main goal was to commend a new, down-to-earth piety to all Christians. This piety was new, because at its center was a radically different meaning of good works that would transform the way believers practiced their faith.This volume is excerpted from The Annotated Luther series, Volume 1.
