Book excerpt: Long assumed to be an unchanging and unquestioned bulwark of established power and privilege, religion in Latin America has diversified and flourished, while taking on new social and political roles in more open societies. How did this change occur? Why did churches in the region embrace new ideas about rights, sponsor social movements, and become advocates for democracy? Are further changes on the horizon? Daniel Levine explores these issues, uniquely situating the Latin American experience in a rich theoretical and comparative context.
