The meaning of the term “post-postsecularity” in the works of Sergei Bulgakov

The research aims to clarify the meaning of the term “post-postsecularity”, considering its representation in modern philosophical discourse and, starting from Jürgen Habermas’s classical understanding of the term “postsecularity”, to find the meaning and theoretical foundations of the concept of “post-postsecularity” based on the works of Sergei Bulgakov. The novelty of the research lies in clarifying the substantive meaning of this concept in determining the parameters for achieving post-postsecularity based on S. Bulgakov’s doctrine of sobornost (spiritual community): setting goals in the direction of eternity with simultaneous immersion in historical reality, moving away from chosenness and isolation, replacing religion with the direct unity of man and God in the real Kingdom of God, the idea of theanthropism, social unity, and considering post-postsecularity as a form of sobornost unity present in historical reality and directed towards eternity, where the disunity of the religious and secular, man, society, church, God is overcome, or a state of God-manhood in which the parameters of sobornost unity are achieved. As a result of the research, it was revealed that S. N. Bulgakov’s prospective vision of the public, both religious and secular, preceded Habermas’s postsecular approach with the idea of solidarity. This vision can be interpreted, among other things, as the seed of the theory of post-postsecularity, where there is no isolated secularity and religiosity, but a single dialectical process in the form of a “positive dialectic” of the historical formation of sobornost.
