In this article, we shall describe the complexity and differentiation that characterizes the state of religion in Italy, beginning with a concise reconstruction of the chief factors that characterize the relationship that Italians experience with their birth religion or the prevailing religion (Catholicism). We shall then describe the level of ethical and religious pluralism (found both within the Catholic universe and, especially, outside of that universe) that Italian society is beginning to experience directly, in part because of the fact that other religious entities (both old and new) are become increasingly visible in the public sphere, adding color and identity to the symphony of voices attempting to speak publicly in religious terms. In conclusion, we shall explore a phenomenon, popular religion, which continues to show extraordinary vitality. The basic hypothesis that we intend to set forth is based on the idea that ordinary Italians consider themselves Catholic but have a variety of different ways of interpreting their practical involvement with the Catholic Church.
