On the Gospel and Repentance - Theological Commonplaces

On the Gospel defines the Gospel carefully as the proclamation of God's promises and forgiveness of sins for the sake of Jesus Christ. Since confusions continually arise over the relationship of the Gospel to the text of the New Testament, Old Testament, and the Law of God, Johann Gerhard carefully distinguishes Law from Gospel and explains how the Gospel is found in both testaments.

On Repentance deals with salutary turning-away from sins, which Lutherans commonly define as including contrition (grief over sins committed) and faith in the promise of forgiveness for Christ's sake. Much of this volume examines the Roman Catholic sacrament of Penance, defined as consisting of contrition, confession, and satisfaction, as well as the concept of indulgences that is bound up with it.
