Book excerpt: Migration has become a defining feature of the contemporary age. It has brought about significant changes in political, economic, social, and religious landscapes. This volume explores a question that has been little considered to date: how are churches being transformed in the face of global migration? The book features contributors from diverse national, denominational, cultural, professional, and linguistic backgrounds. Their essays reveal the ways in which migrants and the phenomenon of migration expose longstanding gaps and failings within Christian communities. However, the prevalence of migration and migrants simultaneously opens up fresh possibilities for churches to grow, renew, becoming more authentic, dynamic, and diverse. Church in an Age of Global Migration presents a collage of embodied ecclesial practices, understandings, and realities that have emerged and are continuing to develop in the face of global migration. Committed to transnational and ecumenical dialogue, and to integrating practical and theoretical perspectives, this volume is the first to offer an in-depth analysis of the ways in which churches are being changed by migrants.
