For me it's quite simple really, they've managed to make behaviour which otherwise would be considered a violent crime, pathological lying and brainwashing acceptable because an invisible man in the sky that only they can see told them to do it. The only reason people get away with it is because of their religion, if someone who wasn't religious used the excuses used to commit crimes they would be declared clinically insane, but wait, the very problem we have here is that there are deeply religious people in power! So no wonder nothing every gets fucking done, they're naturally covering each others' backs.
Everything that your heart says is wrong, its wrong. Like you said your religion say you to "If one doesn't go to the Church on every Sunday, he is a sinner". its wrong because your heart did not believe on it. Because NO one religion bound you to pray. There are out comes if you dont pray, but not the boundness.
Don't forget that they've made a contradictive statement about that for centuries, they say God is everywhere, so why the fuck do they need a Church?
