I always thought the idea of church worshipping was more a social obligation than anything with a lot of inherent meaning behind it, because in my experience people spend more time gossiping, trying to outdo each other in prayer or dress, and feeling utterly bored than they do inspiring one another in practical endeavour toward compassion or peace.
I've watched videos of church ceremonies where people hail God for defending America and giving them all the wealth to 'blow up the terrorists' (more like a ratio of 10 civilians for every terrorist), or services where the pastor gets the crowd so adrenaline charged they're ready to part with a weeks wages, or pastors telling mega-church congregations to shun people of other religions and push oppressive practices against those people.
I think church, as a concept, is so much better when it's good friends with good values sharing food and quietly encouraging one another. The mega-church, the bands, the concert atmosphere, it's a show and a business more than an opportunity for solace, contemplation and psychological rejuvenation in the company of like-minded, peaceable people.
