Abstract

Christianity has recently undergone historic demographic and cultural shifts: it has expanded significantly in the global south while declining in the west. In an age of World Christianity, these changes bring diversity and competition, and renewed Christian witness. The global context for the faith reveals unavoidable tensions between missional expansion and the call to be one in Christ Jesus. Amid plurality and rapid changes in identity, Christians are challenged to re-appropriate the classic marks of the church – one, holy, catholic, and apostolic. Engagement with all four marks, reframed for the contemporary situation, will help to maintain the creative tension between mission and unity, to connect Christians across geography and generations, and to forge a common vision of salvation in an interconnected world.
