Not this kind of 'exposing' again, please. Where's the basis of this statement? I've known several nuns, monks, prophets of islam, and gurus in my life ( i live in a multi-cultural country) who truly serve the communities by spreading peace and true human behaviours. Despite some might pray to more than one god, unity and peace still guide their actions.
All religions are right. Believe what you believe as long as you believe in peace and not war. Anyone who pursues war is a fanatic.
Language and origins are keys as to why there is more than one religion.
What I've been told about Catholicism is that the system is corrupt. Think about it. You're one of the largest religious bodies in the world. Do you truly think that every single one who holds prominent titles is clean by heart? Sorry, but this forum is plain ignorance to me. Google is there for your curiosities. What it says about Catholicism/Roman Catholic Church is below.
"As the world's oldest and largest continuously functioning international institution, it has played a prominent role in the history and development of Western civilization."
Try pointing fingers at this historical religion out there, and you'll be bombarded with logical, historical accuracies that'll prove that this is one of the religions which have constructed the world to what it is right now.
Original Poster (OP) says; This is extremely important since millions of people's souls are at risk here.
No. You're the one at risk with the amount of ignorance you hold in there. Try learning more than one religion and you'll understand. Let the others pray as they want, it's not your business to force them out of their beliefs.
