Sorry, Aaron, didn't mean to offend you. You can disregard my statements b/c they're kind of loaded - based on one particular mega-church that no one here probably knows or cares about. It's more of a personal thing that effected a lot of people I know and has left a sour taste on both sides so we never ignore a chance to hurl one at 'em!
Also, this megachurch tends to say that it's one thing, but then if you challenged these people with some theological issue, they either don't know what you're talking about, or give an answer opposite of what is defined by the denomination they insist so fervently they're part of. Of course, we all differ slightly and change over time - just this week I completely changed my ideas on the Lord's Supper and realized I'd been wrong for 21 years - but if you continuously attach yourself and your church to a particular denomination b/c it's popular or looks good or whatever and then preach the opposite, the credibility factor goes downhill pretty fast in my book.
I criticize the particular church I have in mind because out of all the people I know that have gone there, no one has actually gone there for more than a year. See, to me, a church is as much about building a close community in order to build each other up as well as hold each other accountable, and all the people know that have tried this mega-church just aren't getting that. Also, the pastor is an amazing and inspirational public speaker, but his sermons are just stories and testimonials. There's nothing there that challenges me, nothing that has any real theological value, nothing I can take away and say "huh, I never though about it that way before...". It's basically like a "small group" of 1000 people.
I say all of this pretty much churchless myself, because our Rev. recently left to take a position overseeing a new seminary program, and he was really everything I believed in. His sermons were so thoughtful and challenging....I remember one time he was really going out on a limb with this concept he'd concocted in his head and I remember thinking "I would bet my life that this man has it right". I've never felt even close to that at any of the larger more progressive/contemporary churches I've attended.
But it really boils down to personal preference. I'm very introverted and look at things from a very practical, intellectual approach. Teaching through testimonials and praise songs moves millions of people to tears but does nothing for me. On the other hand, I read a piece by Jonathan Edwards and suddenly feel like my entire life and my existence is worthwhile after all, but others find it boring and useless. I've tried to change how I feel, but the reality is that I can't. We all worship different ways and I've found I can't get what I need from a megachurch.
