What makes religion so powerful? Why does it attract so many followers? Raise so much money? Influence how people vote? The usual answer is that religion is powerful because it offers divine hope. But there is more to it than that. Why does a worship service seem powerful? Why is it powerful to hear someone testify about their faith? Who sets the rules for who can be a member and who cannot? What does religion do to reinforce gender and racial differences? Or to challenge them? _Religion's Power_ takes a fresh look at these questions by examining what happens during religious rituals to signal the leader's power, the power of the deity being worshipped, and, inadvertently, why some people in the congregation are deemed more powerful than others. Robert Wuthnow explores how religious narratives are constructed to demonstrate sincerity, how religious organizations control time by controlling space, how codified knowledge gives religious organizations power, and the small ways in which religion shapes identities and politics. Building on classical work in the sociology of religion and drawing extensively on historical and ethnographic studies, _Religion's Power_ foregrounds cases ranging from nineteenth-century church organ and lightning rod controversies to current clashes about border walls and racial justice. This is a book for beginning students of religion as well as for advanced scholars and for practitioners, fellow travelers, and critics who want to understand better what makes religion powerful.
