This course traces Eastern Christianity from the 2nd to the 16th century. A broad survey course aimed at undergraduates of all concentrations, there are no prerequisites; the course focuses on both Church history and theology. It begins with Constantine's conversion and traces the growth of the church, the rise of monasticism, the creation of the creed (the Councils of Nicea and Chalcedon), and the secession of the Eastern churches (Coptic and Syriac), the role of religious pictures and the iconoclast dispute and relations with the West (Rome) which were frequently strained before the official break in the 11th century. We cover the conversion of the Slavs and the ventual formation of independent Slavic national churches. We treat the fall of the Byzantine and Medieval Slavic states to the Turks and the position of the Orthodox under the Turks. Attention is also given to the Russian Church from the 9th century to the Old Believer schism and Church reforms of Peter the Great. Readings are varied. There is no textbook. A relevant paper of the student's choice, an hour exam, and a final are required.
