As the boundaries between cultures and religions blur in an increasingly globalized world, the church finds itself in need of new approaches to understanding and embracing otherness - both inside and outside of its established communities. Southeast Asia has long been one of the world's most diverse regions, with over a hundred ethnicities represented and members of every major religion living as neighbors. In this rich and complex environment, the church has an equally rich and complex history, at times flourishing, at times floundering, but inexorably taking root. In this collection of essays, contributors from throughout the region reflect on the history and future of Christianity in Southeast Asia, providing an overview of missions in the region, and exploring how local churches are defining a uniquely Southeast Asian approach to interreligious engagement. Combining missiological research with contextual theology, this volume offers profound insight into the challenges accompanying missions in a multireligious environment. From ethnic and religious conflict resolution to navigating hybrid identities, this collection of essays makes an excellent contribution to global conversations surrounding the future of missions in a globalized world.
