The Politics of the Spirit is a masterful study of the political effects of evangelical Protestantism in Central America. Timothy Steigenga's thoughtfully crafted work questions whether the spread of Protestantism in Latin America has reinforced authoritarian elements in political culture or deepened nascent democracy. Steigenga provides a thorough review of the literature on religion and politics in Latin America, putting many of the hypotheses generated in this literature to the test through an analysis of comparative survey data and qualitative interviews.
