This book is an excellent introduction to the issues facing Evangelical Protestants and their ecclesial communities today. Arguing that evangelical churches are overly individualistic and not centered in communities focused on the Trinity, Harper and Metzger provide compelling ways to change the direction of the American church. They cover topics as diverse as worship, interaction with culture, church discipline, ecology, sacraments, service, church order, and gender roles, and many more. This book will serve as an excellent introduction in classrooms to ecclesiology and is an invaluable resource for pastors, deacons, and influential laity who are rethinking what the church is, and what it should be doing.
