Subversive Spirituality links the practice and study of Christian spirituality with Christian mission. It develops a twofold thesis: grace, spiritual disciplines, and mission practices are inseparably linked in the mission of Jesus, of the early church, and of several historical renewal movements, as well as in a contemporary field research sample; and amidst the collapse of space and time evidenced by our culture's increasingly hurried pace of life, more time and space are needed for regular solitary and communal spiritual practices in church, mission, and leadership structures if Christian mission is to transform people and culture in our time. This requires a subversion of the collapsed spatial and temporal codes that have infected our Christian institutions. Jensen employs methods and approaches from a variety of academic disciplines to explore both spirituality in terms of space and time and mission in terms of deed and word. Specifically, Jensen examines the spirituality and mission of Jesus, the early church, the apostolic fathers, Origen, the Devotio Moderna, the early Jesuits, David Brainerd, and several women in 19th century Protestant missions. He considers the spirituality and mission that have arisen within the postmodern generations born after 1960. Based on the theological, historical, cultural, and field analyses of this study, a model for spirituality and mission is proposed. The model addresses the contemporary collapse of space and time and appears to have widespread applicability to diverse cultures and eras. Jensen's model is applied to the pluralistic and postmodern milieu of North America with recommendations for spirituality and mission in church, mission, and educational structures. A derivative model for teaching and practising spirituality and mission in the academy, which also has application for non-formal leadership development structures, is also proposed.
