Churches are businesses and take advantage of the naivity and stupidity of their believers.
The world's two largest religions (Islam and Christianity) are actually hugely successful business enterprises, which uses the brainwashed followers to their own advantage. Even the other religions (Hinduism and Buddhism) are recently following this trend.
I agree with Christianity, but how so about Islam?
But truth to be told 'religion is opium of the people' in most cases. People is just people they don't communicate with almighty God in heavens, they just need to steal your money and build bigger church or better car for themselves. And for that they need a lot of money
