The article presents the attempt of using the marketing paradigm in the analysis of state-confessional relations. Considering such relations through the prism of market structures, the authors identify three main types: religious monopoly, religious oligopoly, and religious monopolistic competition. Religious monopoly implies the dominance of one religion, which enjoys the full support of the state that protects it from competition from other religions. In the modern world, religious monopoly exists in two forms — closed and open, with the differences between the two lying in the degree of monopolization of the market by one of the confessions. According to the authors’ conclusion, the religious monopoly imposed from above (by the state) ultimately has a secular effect, reducing the level of participation of the population in religious activities and thereby weakening the monopoly of religion, which, in turn, can lead to the termination of state support for it. Religious oligopoly implies that several dominant religions or their branches that are equally supported by the state and have the same status compete in the market; the emergence of new ones is difficult (open oligopoly) or even seriously limited (closed oligopoly). Religious monopolistic competition is characterized by the inclusion in the process of competition not only of religions and their branches, but also religious denominations. Each of these “players” produces its own unique religious product and has relatively free access to the market of religions, which is almost not limited by the state. The proposed typology is historical in its nature, which makes it possible to predict the dynamics of state-confessional relations.
