Abstract: The subject of the research is the experience of building a non-religious and pseudo-religious faith as a new Christian anti-tradition. The object of research is post–secularism as a phenomenon of modernity. Comparative, descriptive and content analysis served as the methodological basis of the study. The idea of F.Nietzsche's "death of God" gave rise to a natural backlash from the bearers of religiosity, those for whom the existence of God is a reality. However, this answer was twofold. On the one hand, traditional apologetic polemics. But on the other hand, an attempt to rethink Christianity itself in the conditions of a "grown-up" world, the beginning of which, in many ways, was laid by Dietrich Bonhoeffer. But how justified is such an answer and will an attempt to "revise" Christian values lead to their reduction and then oblivion?      The following main conclusions were made. Protestant theological thought in the middle of the last century made a number of attempts to "adapt" Christianity to the realities of modernity. Dietrich Bonhoeffer put forward the idea of an adult world that has outgrown religion, and Thomas Altitzer laid the foundation for the "theology of the death of God", which makes Christianity irreligious at all. Such ideas desacralize the very idea of the Transcendent. The appearance of openly parodic pseudo-religious constructs and their partial recognition by modern society finally opens up the prospect of the ultimate profanation of the Transcendent due to the loss of interest in Its search, the reason for which was largely the attempts of confessional thought to solve the problem of the "death of God" through the secularization of faith, which, first of all, means the rejection of Tradition and God as incomprehensible The absolute. Such a denial of Tradition and with it the Transcendent, in fact, speaks not about overcoming the "barriers" of religiosity, but on the contrary, about building a new isolation. We can talk not only about the beginning of the "death" of the tradition, which is reborn into an anti-tradition, but also about the futility of "irreligious faith" and "atheistic Christianity" in general.

Abstract: The subject of this research is comprehension of the concept of secularism by theologians of the Abrahamic religious tradition (Christianity, Islam, and Judaism) in the late XX – early XXI centuries. The object of this research is secularism as the phenomenon of modernity. Leaning on the methodology of contextualism, comparative and content analysis, in terms of civilizational approach, the author studies the interpretation of the concept of secularism within the framework of confessional theological discourse. The author has examined the corresponding representations of theologians of the Orthodox, Catholic and Protestant Christian traditions, including the inter-Christian movement of radical Orthodoxy. Analysis is also conducted on the concept of secularism in modern classical Islam and moderate Orthodox Judaism. The main conclusions are as follows: the theologians of all indicated denominations trace the origins of secularism in the West; Islamic theologians agree upon the fact that radical Orthodoxy takes roots in Christianity itself; the representatives of Catholic tradition see secularism as the ideology similar to fundamentalism, however, they deny its universality, and thereby supporting the Orthodox interpretation of secularism. A number of Orthodox theologians view secularism not just as the ideology aimed at achieving the complete elimination religions from public life to purely private life, but also as quasi-religion, which is extraneous to the principles of secularism. Islamic theology believes that secularism, which is alien to the Muslim world, is a serious but not critical challenge brought from the West. Islamic theology tends to see secularism only as ideology, which at times is irrational. Jewish moderate Orthodoxy views secularism as the challenge to traditional meanings that are fundamental to human community. In this regard, they advocate for the so-called ideological consensus between religious belief and secular modernity.
