In this paradigm-challenging study, Peter Cahn investigates why the coming of evangelical churches to Tzintzuntzan has produced neither the interfaith clashes nor the economic prosperity that evangelical conversion has brought to other communities in Mexico and Latin America. Drawing on extensive ethnographic fieldwork, he demonstrates that the evangelicals' energetic brand of faith has not erupted into violence because converts continue to participate in communal life, while Catholics, in turn, participate in evangelical practices. He also underscores how Tzintzuntzan's integration into global economic networks strongly motivates the preservation of community identity and encourages this mutual borrowing. At the same time, however, Cahn concludes that the suppression of religious difference undermines the revolutionary potential of religion.
