This is Volume 2 of the acclaimed three-volume series which has been completely revised to provide a readable, definitive, and completely updated treatment of the evolution of Christian thought from the early church to the great flowering of Christianity in the Middle Ages, through the Reformation and the Enlightenment, to the twentieth century. Volume 2 inludes, From Augustine to the Eve of the Reformation. The other two volumes in this set are sold separately. Volume 1, From the Beginnings to the Council of Chalcedon, and Volume 3, From the Protestant Reformation to the Twentieth Century. Justo L. Gonzalez has added a major new chapter on the twentieth century, has eliminated all sexist language, and - in light of recent scholarship - has completely revised the text and updated the bibliographies.
