This early work of theology is both expensive and hard to find in its first edition. It contains the writings of the twentieth century theologian Reinhold Niebuhr and his thoughts on contemporary religion. This is a fascinating work and is thoroughly recommended for anyone with an interest in the history of religion. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
