The atlas also documents other dramatic trends, including the fragmentation of Christianity. New denominations, often borne out of strife and division, multiply endlessly. In Korea, for instance, there are now 69 different Presbyterian denominations. At the rate we are going, by 2025 there will be 55,000 separate denominations in the world!
That is an utter mess fueled by rivalry and confusion that hampers the church's witness and makes a mockery of God's call to live as parts of one body.
The atlas also documents the dramatic rise of revival movements throughout the world, and charts the story of Pentecostalism's rise. From its beginning a century ago, Pentecostalism now comprises a quarter of all Christians in the world. This fundamental change in Christianity's global composition, along with its geographical transformation, has created a dramatically different Christian footprint in the world.
