Building on the work and legacy of Darrell L. Guder, Converting Witness: The Future of Christian Mission in the New Millennium constructively explores key questions and new possibilities in the field of missiology in light of the context of world Christianity. The conversation around missional theology and the missional church sought to address the gap between theology and mission and foster renewal within North American Christianity, but the growing consciousness around world Christianity has forced theologians and missiologists to give greater consideration to global cultural diversity. Many of the classic categories and methods-such as church planting, catholicity, and even the term world Christianity itself-are in need of fresh examination and thoughtful analysis. The contributors to this volume address a range of important missiological topics, including globalization, interfaith dialogue, integral mission, intercultural hermeneutics, and church practices.
