This course follows the extraordinary development of Western Christianity from its early persecution under the Roman Empire in the third century to its global expansion with the Jesuits of the early modern world. We explore the dynamic and diverse character of a religion with an enormous cast characters. We will meet men and women who tell stories of faith as well as of violence, suppression, and division. Along the way, we encounter Perpetua and her martyrdom in Carthage; the struggles of Augustine the bishop in North Africa; the zeal of Celtic monks and missionaries; the viciousness of the Crusades; the visions of Brigit of Sweden; and the fracturing of Christianity by Martin Luther’s protest. We hear the voices of great theologians as well as of those branded heretics by the Church, a powerful reminder that the growth of Christianity is a story with many narratives of competing visions of reform and ideals, powerful critiques of corruption and venality, and exclusion of the vanquished. The troubled history of Christian engagement with Jews and Muslims is found in pogroms and expulsions, but also in the astonishing ways in which the culture of the West was transformed by Jewish and Islamic learning.
