Last month, I was at an outdoor festival in rural North Carolina for progressive evangelical Christians. It was called the Wild Goose Festival and featured leading "emergent church" advocates like Brian McLaren, Phyllis Tickle and Tony Jones.When I saw the stage, the floodlights were shining on the black mass of musicians with their long hair, black T-shirts, caps and ink-stained arms. The half-dozen people known as The Psalters emitted an ancient sound, a dinosaur-like crunch, crunch, crunch. Low barbarous rants and throaty ultra-masculine roaring was amplified from a dual tower of speakers.The Psalters were soft spoken, easy to laugh, jocular but gentle. Could this be a vision of a Christian future? Is this what church looks like after our consumer-oriented, fossil-fuel dependent lifestyles-apparent by the thousand or so late-model cars in the festival parking lot and the social justice booths adorned with consumer enticements-dissipate?
