Written by an eminent theologian, it combines in its narrative a rare blend of clarity, unity, and balance. In light of significant advances in scholarship in recent years, extensive revisions have been made to this fourth edition. Three scholars from Union Theological Seminary in New York have incorporated new historical discoveries and provided fresh interpretations of various periods in church history from the first century to the twentieth. The result is a thoroughly updated history which preserves the tenor and structure of Walker's original, unparalleled text.
