The insights of the early church hold vast potential for strengthening the community life and ministry of the contemporary church. Robert Webber sounded this theme in his original 1978 edition of Common Roots. Over the past thirty years, this book has been recognized as Webber's seminal work, providing a foundation for the ancient-future faith movement. Here is Webber's original clarion call, presented with an extensive foreword by David Neff, editor-in-chief of Christianity Today magazine and executive director of the Robert E. Webber Center for an Ancient-Evangelical Future. The book will promote new conversations about ancient-future faith and its relationship to modern evangelicalism. Webber examines evangelicalism through the lens of the early church (AD 100-500). He searches for the roots of evangelical Christianity, then challenges contemporary evangelical beliefs and practices that are out of harmony with historic Christianity. These ancient patterns, Webber contends, contain wisdom evangelicals must recover for worship, theology, mission, and spirituality. Chapters highlight a problem, investigate an ancient belief or practice, and suggest an agenda for today. This knowledgeable perspective on ancient-future faith is perfect for both seasoned scholars and a new generation of evangelical Christians.
