“Diffused religion” is to be understood in at least a double sense. First of all, it is diffused in that it comprises vast sections of the population and goes beyond the simple limits of church religion. Besides, it has become widespread, since it has been shown to be a historical and cultural result of the almost bi-millennial presence of the Catholic institution in Italy and of its socializing and legitimizing action. However values diffused in the Italian civil society can be considered as a form of conflict with the established institution of Catholic Church. Civil society shows a peculiar trend towards civic freedoms and ethical pluralism. Although the Catholic perspective is dominant, the civil society prefers a different system of values, even though not so much different from ecclesiastical social doctrine. This way there is a public space where religion is not the reference point and other perspectives take place.
