Sociologists of religion widely concur that Sociology of Religion is a marginal discipline within contemporary Sociology. Some of them hope for better future and connected this hope with spreading doubts concerning the secularization theory. These doubts, on the other hand, mean significant theoretical challenges and put under questions foundations of the discipline. Following analysis shows that drawing boundary between religion and non-religion – as an act of setting up the object and an independent agenda of the discipline – might have been a premature act. In its view many contemporary troubles of the discipline might be solved by revising this premature decision and by re-emphasising fundamental issues of Sociology (i.e. dynamics of social ordering) with the Sociology of Religion.
