In 1910 Protestant missionaries from around the world gathered to explore the role of Christian missions in the twentieth century. In this collection, leading missiologists use the one hundred year anniversary of the Edinburgh conference as an occasion to reflect on the practice of Christian mission in today’s context: a context marked by globalization, migration, ecological crisis, and religiously motivated violence. The contributors explore the meaning of Christian mission, the contemporary context for mission work, and new forms in which the church has engaged-and should engage-in its missionary task. From these essays, a vision of twenty-first-century mission begins to emerge-one that is aware of issues of race, gender, border spaces, migration, and ecology. This renewed vision gives strength to the future of shared Christian ministry across nations and traditions.
