Church shopping, marketing, and the not-so-sanctified practices that go with them make easy targets for criticism. But competition among churches for worshippers has always been fierce in the United States, to the benefit of American religion and individual churchgoers. The prohibition against establishing an official state religion helped give us the shoppers' paradise that is our religious marketplace. Disestablishment (Massachusetts was the last state to cut ties to its official church, in 1833) meant that preachers had to learn to get along without support from the state. It made the ability to recruit and keep a flock—and get them to give generously—crucial to a church's survival. In 1992, Roger Finke and Rodney Stark argued in The Churching of America, 1776-1990 that this produced a ministry modeled on capitalism, with pastors acting as the church's sales force.
