Recent efforts to write the global history of Christianity respond to demographic changes in Christianity and use “global” in three ways. First, “global” suggests efforts at more comprehensive historical retrieval, especially to place the beginnings of Christian communities not within mission history but within the church history in those areas. Second, “global” can refer to the broader comparative perspectives on Christianity's history, especially the history of religions. Finally, “global” can indicate attempts to retell the entire Christian story from a self-consciously worldwide perspective. Recent works also raise new theological and pragmatic challenges to the discipline of church history.
