How many members does Christianity have worldwide?

Answer 1

Christianity is the predominant religion of the world. It has been estimated that there are currently around 2.2 billion Christians in the world, as opposed to 1.2 billion moslems, 800 million hindus and 360 million Buddhists. This number (2.2 billion) represents around 34% of the world's population, including those who have no religion at all, or 40% of the world's population that have a religion.

This number is just an estimate, as there are some countries - notably China - where Christianity is growing repidly, and, because of threatened persecution, many Christians there are very secretive of their faith making data difficult to obtain. Nevertheless, it is believed that in China alone there may well be 0.1 billion Christians which is likely to triple in the next decade if growth in the Chinese Church continues at the same rate.

Answer 2

I suppose that you would say that technically no one did, as Christianity as such started after Jesus' death, resurrection, and ascension. If you are asking abut how many followers or disciples Jesus had, there is no record of that, although we can say that the number was greater than 500, based on I Corinthians 1:5.

Answer 3
