This book is a study of ancient and medieval Christology. Employing a range of interdisciplinary methods derived from the fields of social history, discourse theory, ritual studies, and the visual arts, the book demonstrates how Christian identity in Egypt was shaped by a set of replicable ‘christological practices’. It traces the fascinating lines of the Coptic church's theological and cultural transition from late antiquity to Dar al-Islam. The book includes translations of Coptic and Arabic texts which allow non-specialists access to these important documents for the first time.
