The article reviews the concept of “cultural religion”, pursuing its different modulations. The limits of the idea oscillate between its interpretation as a form of obsolescence of religion in secularized societies and the possibility that it is a specific modality of religious identification. However, this theoretical construct does not sufficiently incorporate a focus on the processes of cultural transmission in complex societies. From the notion of “cultural mediation (medium)”, an observation framework of contemporary Portuguese society is attempted in order to identify the structuring dimensions that facilitate the mobilization of religious memory in different logics of action.
