1897. Other volumes in this set include ISBN number(s): 0766155048. Volume 2 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 continues 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; and Book IV: the doctrinal views of Luther presented in systematic order.
