Last night I came across a website called Verge Network, created a few years back to feature the "missional movement" among churches (most seem to be mega churches--haven't yet found the source.) I looked through some very good preaching and high tech videos, but after an hour of browsing I felt I'd had enough of seeing preachers in jeans and t-shirts, dark, massive assembly halls, waving arms, spot lights, cluttered stages with guitars and Peaveys and floors littered with cords. But that's how "successful" churches do it these days. Join the culture in order to reach the culture.
A few centuries ago, soaring arches, stained glass windows, marble statues, and amazing organs and choirs were all meant to appeal to the senses, particularly for those who couldn't read. Nothing has changed, I guess—except then the churches seemed to be leading the culture.
