The links between religion and politics have a long history, and studies of them are relatively numerous. In France, the dominant model during the 1960s—which revealed the intensity of the relationship between right-wing voting and integration to Catholicism—is now being questioned. Concurrent models insist on the pluralism of Catholicism and the consequences of plural politics. This article examines the relevance of two models on the one hand, and tests them by applying them to various European countries on the other. It demonstrates that the relationship between religion and politics remains intense and relatively stable no matter which country is studied or which religion is considered. As such, despite the need for some adjustments to the first paradigm, it is no less true that this it is still valid for analyzing the religion-politics couplet.
