The present course is an overview of radical forms of Christian spirituality. It takes a historical approach to the study of eight expressions of radical Christian spirituality and relates them to the notion of transformative leadership. The aim of the course is to equip students with methodological tools for the historical examination and appropriation of spiritual practices. Its narrative parallels the diachronic development of global Christianity from the sixteenth to the closing decades of the twenty-first century. It is prefaced with an introduction to the historical-critical study of spiritual practices. It will examine the meaning of radicalism as a highly contextualized historical construct, a modality of practicing faith, and a contemporary sociological category. The course then examines eight expressions of Christian radicalism, namely: Swiss Anabaptism, Diggers, Quakers, Christian Anarchism, the Catholic Worker Movement, African-American Liberation, Latin-American and 2/3 Worlds Liberation, and the Sanctuary and New Sanctuary Movement. Special attention will be given to spiritual practices articulated as an expression of Christian non-violence, anti-militarism, and anti-imperialism. Movements and figures considered include Thomas M?ntzer (1490- 1525), Andreas Rudolf Bodenstein von Karlstadt (c. 1480-1541), Gerrard Winstanley (1609- 1676), Margaret Fell (1614-1702), Nat Turner (1800-1831), Leo Tolstoy (1828-1910), Luisa Capetillo (1879-1922), Dorothy Day (1897-1980), Jacques Ellul (1912-1994), James H. Cone (1938-), and Jon Sobrino (1938-). While emphasis will be placed on the synchronic interpretation of practices, due attention will also be given to their development over time.?
