Celebrating the fortieth anniversary of this seminal book, this new edition includes an illuminating foreword by Carlos Eire and Ronald K. Rittges The seeds of the swift and sweeping religious movement that reshaped European thought in the 1500s were sown in the late Middle Ages. In this book, Steven Ozment traces the growth and dissemination of dissenting intellectual trends through three centuries to their explosive burgeoning in the Reformations-both Protestant and Catholic-of the sixteenth century. He elucidates with great clarity the complex philosophical and theological issues that inspired antagonistic schools, traditions, and movements from Aquinas to Calvin. This masterly synthesis of the intellectual and religious history of the period illuminates the impact of late medieval ideas on early modern society. With a new foreword by Carlos Eire and Ronald K. Rittgers, this modern classic is ripe for rediscovery by a new generation of students and scholars.

The Catholic Church's claims to spiritual and temporal authority rest on Jesus' promise in the gospels to give Peter the keys to the kingdom of heaven. In the sixteenth century, leaders of the German Reformation sought a fundamental transformation of this "power of the keys" as part of their efforts to rid Church and society of alleged clerical abuses. Central to this transformation was a thoroughgoing reform of private confession.

Unlike other Protestants, Lutherans chose not to abolish private confession but to change it to suit their theological convictions and social needs. In a fascinating examination of this new religious practice, Ronald Rittgers traces the development of Lutheran private confession, demonstrating how it consistently balanced competing concerns for spiritual freedom and moral discipline. The reformation of private confession was part of a much larger reformation of the power of the keys that had profound implications for the use of religious authority in sixteenth-century Germany.

As the first full-length study of the role of Lutheran private confession in the German Reformation, this book is a welcome contribution to early modern European and religious history.
