Building on the work and legacy of Darrell L. Guder, Converting Witness: The Future of Christian Mission in the New Millennium, explores key questions and new possibilities in missiology in light of the world Christian context. The conversation around missional theology and the missional church has examined the gap between theology and mission with the intent of fostering renewal within North American Christianity. But this can only fully occur in relation to the reality of world Christianities and the framing significance of 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.
