Substantially revised and expanded — and reorganized into a two-volume paperback edition — this introduction to modern Christian thought provides full, scholarly explorations of the major movements and thinkers, theologians, and philosophers in the Christian tradition since the eighteenth-century Enlightenment — together with historical background and critical assessments. It deals with the entire modern period and is the first book to include extensive treatment of modern Catholic theologians and philosophers as well as Protestant thinkers and movements. Volume I covers the modern period from the Enlightenment through the nineteenth century. Volume II explores the important movements, theologians, and religious writers of the twentieth century, including recent developments at the end of the century.
