Theology and the churches are often considered to be at the margins of contemporary culture, frequently struggling for identity and attention. In this important new book Martyn Percy argues that a rich form of practical theological engagement is needed if the churches are to comprehend their situation in the modern world, thereby enabling them to engage more confidently with society. Drawing on a range of perspectives in the religion-culture debate, and from case studies in the USA and Europe, the book explores the myriad of ways in which culture is now shaping contemporary Christianity, and how vital an appreciation of this dynamic is for the self-understanding of churches and theology. This book explores the crucial and continuing contribution that theology can make to public life, in an era that is often perceived to be dominated by consumerism and secularity. It will especially appeal to scholars of contemporary religion, practical theologians, and all those who are engaged in ministerial formation.
