The article, based on a generalization of historical facts, examines the active status of the Ukrainian Greek Catholic Church (UGCC) in the system of Eastern Catholic Churches (ECC) by clarifying the specifics of their emergence and development, reveals the special role of the UGCC in ecumenical communication between the Eastern Catholic Churches, and outlines the prospects of this movement in the process of establishing and strengthening relations between Catholics and Orthodox in Ukraine and around the world. The authors propose to use the results of the study to correct the Ecumenical Concept of the UGCC, complementing the strategy of the UGCC in matters of interfaith communication with concrete steps in cooperation with the ECC.
