Book excerpt: This volume examines the Melkite church from the Arab invasion of Syria in 634 until 969. The Melkite Patriarchates were established in Antioch, Jerusalem and Alexandria and, following the Arab campaigns in Syria and Egypt, they all came under the new Muslim state. Over the next decades the Melkite church underwent a process of gradual marginalization, moving from the privileged position of the state confession to becoming one of the religious minorities of the Caliphate. This transition took place in the context of theological and political interactions with the Byzantine Empire, the Patriarchate of Constantinople, the Papacy and, over time, with the reborn Roman Empire in the West. Exploring the various processes within the Melkite church this volume also examines Caliphate–Byzantine interactions, the cultural and religious influences of Constantinople, the synthesis of Greek, Arab and Syriac elements, the process of Arabization of communities, and Melkite relations with distant Rome.
