In this second edition to her highly-lauded debut, Frances Young enhances and expands upon her original work to bring you the most reliable Christian scholariship available on the patristic events spanning from the first to the fourth Ecumenical Council (325-451AD). Covering a range of patristic authors from Athanasius to Theodoret of Cyrus, Young provides detailed information on the controversies that developed, the church fathers who rose to defend orthodox Christianity, and those whose teachings were subsequently condemned. With updated bibliographies and a new chapter not found in the original edition, this volume will be of immeasurable worth to students and pastors devoted to Christian history.
