Financial gain? We're speaking of religion, not vanity churches. If people want to believe in something above themselves, you have no right to say otherwise just because you yourself believe against it. And the fact you believe all religion is directly tied to money really speaks numbers to how you see things you don't like.
There would be no religions if there wasn't churches pushing them. People can believe in the tooth fairy for all i care. Doesn't make it true or possible.
