The Papacy and the Orthodox examines the centuries-long debate over the primacy and authority of the Bishop of Rome, especially in relation to the Christian East, and offers a comprehensive history of the debate and its underlying theological issues. Siecienski masterfully brings together all of the biblical, patristic, and historical material necessary to understand this longstanding debate. This book is an invaluable resource as both Catholics and Orthodox continue to reexamine the sources and history of the debate.
