Quid pro quo religii i polityki. O dawnym i współczesnym zapożyczaniu kategorii religijnych przez politykę w Europie

The article quid pro quo of religion and politics focuses on the process of borrowing religious categories by the political sphere in Europe (so called quid pro quo process). The article starts from the recognition of that process in the history of European politics. By referring to the works of E. Kantorowicz on the medieval monarchy and C. Schmitt on the national state, the author also reveals the method of analyzing the process of quid pro quo. The second part of the article aims at searching for that process in the current European politics. By exploring two principles of EU (subsidiarity and unity in diversity), the author shows that also today European politics uses categories grounded in religious reflection. Nevertheless, the analysis also reveals that today usage of the religious categories is connected with important modifications in the semantic content of the used terms. That observation leads to more general conclusion, made in the third part, on the role of secularization in the political process.
