A summary and reinterpretation of Weber's Sociology of Religion and The Protestant Ethic and the Spirit of Capitalism provides the framework within which four contemporary studies in political culture, which purport to be in the Weberian tradition, are examined. The framework distinguishes three levels of analysis in which “religion,” as a social fact, can be defined. The social, economic, or political consequences that can be attributed to religious adherence are different depending on the doctrine of the charismatic founder, the practical religion, or the practical religion of the converted. The author suggests a new, perhaps more fruitful agenda for research based on the methodological arguments of the paper.
