Caution: may inspire readers to re-think church and, if necessary, begin again. A surprise phone call leadsto a challenging assignment: plant a new church in the oldest church building in downtown Ottawa. Working without a playbook and without much time, the author scrambles to get church up and running in the midst of neighbourhood battles and theological controversies. ReInvention: Stories from an Urban Church is the story of this urban church plant, told through the eyes of its pastor, a former entrepreneur and quantum physicist. It IS also the story of the profound and often disturbing changes currently taking place in mainline churches across North America. Often humourous, sometimes poignant, but always hopeful, these stories from an urban church plant serve as both spiritual autobiography and as manifesto for the paradigm shift that is taking place in today's church. In these days of declining membership in mainline congregations, a new church plant is a rarity. Even more so, perhaps, when the church plant involves an existing 145-yearold building, and a focus on ministry to college and university students, young adults living in the neighbourhood, and those experiencing homelessness and dealing with poverty. In ReInvention: Stories from an Urban Church, Mark Whittall shares the insights and wisdom he and a small-but-dedicated team gained as they worked to establish a new congregation in St. Albans Church, the second oldest Anglican parish in Ottawa.
