Institutionalizing transformations of the Greco-Uniate Church in the context of the ethnoconfessional policy of Russian autocracy (1772-1795).

The status of the Greek Uniate Church on the eve of the division of the Commonwealth was characterized by the institutional design and ordering of the internal church mechanism, centralized management and the integrity of the hierarchical structure, the presence of a multimillion parochial flock and a powerful network of monastic cells, the acquisition of significant economic potential, in particular, the church monastic land tenure, for the conclusion that the entire church body is quite stable. Created by the efforts of the intellectual core of the Greco-Uniate Church - the Order of St. Basil the Great - a multicomponent system of educational institutions (novitiates, seminaries, colleges, parish schools), as well as publishing centers have made a significant contribution to the cultivation of national culture. Thus, for a long time, this Church not only played the role of a kind of ethnoconservant of the culture of the autochthonous population of the Right-Bank Ukraine, retained the dominant elements of its ethnic attributes, but also joined and united its elite with the European spiritual and cultural space.
