The author invites readers to explore both the basic meaning of the Christian understanding of mission, and new developments in mission theologies. After describing the various 'captivities of mission' with plague North American Protestantism, the author argues for a robust and engaged practice of mission, beginning in congregations and extending to the broader Christian community. This volume provides a training overview of the theological issues and the history of mission that will inform theological students, pastors, lay study groups, and congregational leaders.
