This course will examine the history of the Orthodox Christian churches (including "Eastern," Assyrian and Oriental Orthodox) from 1204 to the present. Key topics will include Orthodox relations with Roman Catholic and Protestant communities, with Islam, and with Communism, as well as hesychasm, liturgical reform, missions, Orthodox ethnicism, the Orthodox "diaspora," and the growth of Orthodoxy as a Western phenomenon. Throughout the course, emphasis will be placed on engaging with primary sources. In addition, we will pay special attention to the nature of Church History as a discipline, what it means to study Christianity during an often difficult time, and the pastoral mission of Church historians.
