This brief quote captures the topic of this book: “Mennonites have long referred to themselves as ‘The Quiet in the Land,’ but their actual historical experience has been marked by internal disquiet and contention over religious values and cultural practice. As Fred Kniss argues in his impressive study of Mennonite history, the story of this sectarian pacifist group is a story of conflict. How can we understand the ironic phenomenon of Mennonite conflict?”
