In Nigeria alone there are seven times as many Anglicans as there are Episcopalians in the United States. The Republic of Korea now has four times as many Presbyterians as America. The fast-growth high energy areas for Christianity are in Korea, Africa and even among the outcasts of India, who find in Christianity the hope and dignity denied them by India's rigid caste system. While Christianity is seen as the religion of the successful West, for the first time in history Christianity has become a religion mainly of the poor, the marginalized and the powerless. Christianity is no longer the white man's religion, says Larry Eskridge of the Institute for the Study of American Evangelicals at Wheaton College.
Pentecostalism is a great factor in fast growth areas.
The world is very religious, but very subdivided in our religous expressions. But for the first time, every country in the world claims to have Christians among its population.
