Oh, to be a young believer in Philadelphia right now, where the spirit of Christian activism is mingling vigorously with an apparently unkillable strain of old-school countercultural Jesus-freakery. Here, if you’re listening, you’ll hear hosannas on the streets, and a flavor of tambourines. A band called Psalters mounts an ululating, multi-drum offensive against the capitalist hegemony. They dress the part, too—if you saw this lot coming on a dark night, you’d run. The dreadlocked Shane Claiborne is here, author of The Irresistible Revolution (2006) and a leader of a movement known as the New Monasticism. Claiborne co-founded the Simple Way community in Philadelphia’s Kensington neighborhood in 1998, and the area has since grown to include a branch of the young storefront evangelical church Circle of Hope.
