Protestentism world map
A map of Protestantism (including Anglicanism) by population percentage.

Estimates of the total number of Protestants are very uncertain, partly because of the difficulty in determining which denominations should be placed in the category. It seems however clear that Protestantism is the second largest major group of Christians after Catholicism by number of followers. Often that number is put at 800 million. Some sources, which put the number at 800 million, include also Anglicanism (see below) within Protestantism. However, the 33,000 Protestant denominations in the world differ vastly to slightly theologically and do not form a single communion.

Eastern Lightning, which is in turn an offshoot of The Shouters, is very hierarchical (in contrast to its predecessors) and teaches that Christ has already returned as a woman named Lightning Deng.
