my opinion:
a church is a political organization. it tells people how they should or should not live. it asks for donations. it's a force in the local community. it even [some] can tell you which politician you should or shouldn't vote for.
that being said, if you are a [spiritual] person, then what do you need a church for? what purpose does it serve? if you believe that god hears you all the time and that he answers your prayers no matter where you are, no matter what time of day, no matter what the situation, then why would you need a special building to go to once a week to pray? on top of that, this building is essentially useless for the rest of the week. there are millions of homeless people who don't have a roof over their heads at night, yet a giant building stands empty, because 'god' supposedly lives there? does that make any sense?
