Christianity is the world's largest religious grouping. It underwent massive change in the twentieth century, and seems poised to undergo major transformations in the next. In this important and timely book, one of Christianity's most prolific and respected writers examines these changes, and their implications for the future. Will Christianity survive? And if so, in what forms? And what might its impact be upon culture? How does its past affect its future? What does the future hold for the various types of Christianity? This witty yet highly informed book deals with issues such as the crisis in confidence within western Christianity, the impact of postmodernity on Christianity, and the shift in numerical strength from the west to Africa and Asia. It questions whether traditional Protestant denominations are likely to survive in their present form, and charts the rise of various forms of post-denominational Christianity. It explores the impact of a consumer culture on western Christianity, and the changes this has brought about in approaches to evangelism and church growth. Finally, the work documents the gulf that has opened up between academic theology and the life of the church, and offers a penetration Gramscian analysis of how this situation has arisen, and what can be done to remedy it. Accessibly written, this book will be essential reading for students, academics and general readers interested in religion, Christianity, postmodern theology, and the key controversies in current Christian thinking.
