Bayer shows how Luther comes to see that the promise requires a reshaping of the sacrament of penance (confession and absolution), as well as Baptism and the Lord's Supper. Luther's new understanding of promise also leads him to radically rethink his understanding of Christology, the sermon, meditation, and prayer.
When this book was first published in 1971 it was hailed by the Roman Catholic scholar Otto Hermann Pesch as a "classic of Luther research," and that claim still holds good today. No serious Luther scholar can afford to ignore it. It has also remained the foundation of all Oswald Bayer's subsequent work. The Lutheran Quarterly Books edition of Promissio now offers scholars and students this wisdom in English, thanks to Jeffrey Silcock's careful translation.
