Abstract

The article is dedicated to the problems of ecumenical movement in Ukraine. The Ukrainian Orthodox Church had universal point of view on the problem of union of the Catholic and Eastern-Orthodox Churches. The original Patriarchate of Kyiv has been split twice on the question of Constantinople or Rome, first after the Union of Florence (1439) and second after the Union of Berestja (1596). In the middle of the XVII-th century Petro Mohyla considering that between the Orthodox and Catholic churches there exist many common points and that the differences are only of a formal character, the Patriarch of Kyiv attempted to delineate those items where an accord or a compromise were possible. The ecumenical actions of Petro Mohyla should serve as a laudable precedent and example in the efforts undertaken in recent years toward the union of the churches. Key words: Ukrainian Orthodox Church, ecumenical tradition, P. Mohyla.
