This mystical positivity seeped into the American megachurches, as celebrity pastors became motivational speakers in robes. In one of the great untold stories of American religion, the proto-Calvinist Christian right — with its emphasis on sin and self-discipline — has lately been replaced by a stitched-together faith known as “prosperity gospel,” which holds that God wants believers to be rich.
