Book excerpt: Building on an ethnographic study of St. Michael-le-Belfrey Church in York, a recognized leader in charismatic renewal, mission, and evangelical innovation since the 1960s, this book explores how a persistent tradition of cultural engagement may generate growth, while at the same time bringing about significant changes in the structure and function of the evangelical congregation, and in the social construction of Christian identity itself. This is the first sociological study of St. Michael-le-Belfrey and the first to take seriously the question of how blazing the trail in terms of mission, worship, and fellowship influences the way in which congregations exist as Christian communities within the contemporary British context.
