Spiritual Marketplace: Baby Boomers and the Remaking of American Religion, by Wade Clark Roof
"We have three services now. Are you still game?,” asked the Georgia pastor when he invited me to preach. “Worship is pretty much the same at the early and the 11:00 a.m. services, though the choir sings only at 11:00. The 9:30 service is where we take our ties off.” Sure enough, an informal service with percussion, violin, flute, piano and praise music was sandwiched between two traditional services at this venerable church.
