I have friends who have suggested that the emerging church idea is the predictable fruit of churches that tailor their youth ministries to whatever style is currently fashionable, hold alternative church services for the youth in a separate building (”the youth building”) and never incorporate them into the actual life of the church itself. They’ve grown into adulthood while their styles and preferences were catered to in a special “church” service all their own. The actual church service was something they weren’t expected to like. Many of them were never really exposed to worship in the context of the actual church, with real adults. They were deliberately entertained instead, and thus they were conditioned to think that way. They grew old, but they never grew up, and now even as adults, they want to continue to play at church, but outside the mainstream of the historic church. (My friend characterized the emerging church worship style as “Church services for the ADHD generation.” Read the Christianity Today account of Emergent’s national convention and you will understand why he said that.)So keep on building your youth ministry on the sand of entertainment and excitement if you must. Warm the kids up to worship with skits and games. Dream up grosser and more outlandish spectacles. Keep on denying that what you reach them with is what you reach them to. And maybe one day you'll have your own little heretical kingdom that rises from the ruins of the Emerging Church.
Just don't forget to use your sermons to scorn all the small-minded people who said this was a bad idea. (Ha! Silly me. Sermons are so first century.)
