I just wrote an article on this a couple of weeks ago....
Christianity - 2.1 billion
Christianity was founded in 30 CE. Around 32% of the world is Christian. Christianity is an umbrella term that covers Catholic, Anglican, United, Jehovah Witness and other similar traditions. About half of the 2 billion Christians are Catholic
The second largest is Islam, with1.5 billion followers
you coul be right about Islam surpassing Christianity soon, Christianity is losing followers faster than any other religion woldwide right now.
right now it's christianity, though supposedly Islam ir right up there & is expected to surpase Christianity soon.
not really bcuz of that. Islam is multplying faster than any other religion at the time.
