Ironically, while Europe has moved away from Christianity, the Christian religion has been expanding its influence in Central and South America, in Africa, and in Asia. For the first time in history, Christianity has become a universal religion. It is in fact the only religion with a global reach. Buddhism and Islam, like Christianity, are religions with global aspirations, but these aspirations have not been realized. Buddhism never established itself even in the land of its founding, India, although it found adherents in the cultures of Southern and Eastern Asia. Even though it has a few followers in the West, Buddhism remains a religion with, at best, a regional impact. Islam is vastly stronger, buteven Islam is regional, with little or no sway in the United States, Canada, Central and South America, or Australia. By contrast, Christianity is a force on every continent and in every major region of the world, with the sole exception of the heartland of Islam, the Middle East.

The new face of Christianity is no longer white and blond but yellow, black, and brown. “If we want to visualize a typical contemporary Christian,” Philip Jenkins writes in The Next Christendom, “we should think of a woman living in a village in Nigeria or in a Brazilian favela.” The vital centers of Christianity today are no longer Geneva, Rome, Paris, or London. They are Buenos Aires, Manila, Kinshasa, and Addis Ababa. “The era of Western Christianity has passed within our lifetimes,” Jenkins observes, “and the day of Southern Christianity is dawning.”

In 1900, more than 80 percent of Christians lived in Europe and America. Today 60 percent live in the developing world. More than two out of three evangelical Christians now live in Asia, Africa, and South America. Here are some numbers Jenkins provides: Europe today has 560 million Christians and America has 260 million, yet many of these are Christian in name only. In comparison, there are 480 million Christians in South America, 313 million in Asia, and 360 million in Africa. The vast majority of these are practicing Christians. There are more churchgoing Presbyterians in Ghana than in Scotland.
