This post is worth a read. It also needs serious balancing. There's no mystery (or glory) in why Christians are presently abandoning "church" in droves. It's the same reason divorce statistics shot up several decades ago. Marriage was equally difficult before 1960 and Institutional Christendom is no more controlling today than it has been at any time in the past. What's enabled folks to quit Sunday service is the same thing that enabled husbands to start dumping their wives, and vice versa.
"Quitting church" has, purely and simply, passed the tipping point of acceptability.
Don't get me wrong. I'm all in favor of dropping the traditional weekly parade, but the reasons folks give for their leavings are all over the board, and yet the most common denominator is selfishness, if not outright libertinism. "I wanted more community." "I didn't think ___ was right/wrong." "My questions weren't honored." Those may well betray genuine problems in ALL parts of Christendom today, but they also betray a mindset of convenience and entitlement. Not to come down too harshly, but if we're all just looking for a place we like better, how is that any different from what the whole world is doing, right now?
Look, I know I'm not above all these critiques myself. Not hardly. But let's not go overboard and glorify what are really our own failings. Do you want to know why "church" stinks, really? Most of the time, it's because *we* don't do anything proactive to help make it better.
UPDATE: the conversation below Ian's post has been excellent. Go give it a scan.
