The Politics of the Spirit is Timothy Steigenga's long-awaited quantitative study of religious affiliation and political behavior in Central America. What he has done in this spare and conscientious study is to take to task the “conventional wisdom” about Protestantism in Central America. This is a formidable endeavor, given the flood of scholarly literature that has been produced by anthropologists, historians, and sociologists about Protestantism, and especially Pentecostalism, in Latin America over the past two decades. Because Pentecostalism seemed to emerge in Central America during the region's political crisis of the late twentieth century, much of this literature carried with it a highly deterministic subtext, defined by Max Weber and by models of political behavior borrowed from the United States and European experiences.
