Volume 1 of 2. The life of Martin Luther was one so unique in its personal characteristics and so full of dramatic interest that we are prone to rest content with the contemplation of its outward aspects, and too seldom stop to trace the course of the full, deep current of religious thought that lay beneath it. This volume contains Book I: the inner life and the doctrine of Luther before the indulgence controversy; Book II: the great Reformation testimony of Luther, from the promulgation of the ninety-five theses until the Diet at Worms, AD 1517 to AD 1521; and Book III: the principal points in which an advance is manifest in the doctrine of Luther after his retirement at the Wartburg: developed in opposition to tendencies which appeared upon the territory of the Reformation itself.
