For at least two centuries Europeans, in particular the political elites of Europe, have assumed that modernity and the rational character of the civilization require a marginalization of religion. A separation and juxtaposition of reason and faith, sci-ence and religion or the state and the church are regarded as almost obvious. Gradual-ly the legitimate principle of religious freedom has started to be understood as a pos-tulate of “purification” of public life from any references to sacrum and religion itself as an area of irrational and random opinions has been located in the private sphere. This has led to the conviction that religion (Christianity) does not have or should not have any significance in social life, the public order, the legal system or the widely understood political sphere . The central issue of the paper, which is the possibility of reversing the direction taken by European civilization, is conditioned not only by making the secularist policy of the West more friendly towards Christian tradition (for instance by grounding it on natural law) but still more by the revitalization of religious life of the Churches and Christian communities.
