Abstract

In his work "Religion and Church in the History of Ukraine," V.Lipinsky primarily answers the question: Did Volodymyr the Great accept Christianity in the time when Byzantium was still in connection with Rome and the prince was "Uniate", but "Orthodox"? Volodymyr the Great accepted Christianity in time when there was no official gap between Byzantium and Rome, but the relationship between these two Christian hierarchies was already very tense from the days of Photius, which is about a century before Vladimir baptism. The controversy over the primacy between the Pontiffs and the Constantinople Patriarchs did not accept yet the character of the complete rupture and these two hierarchies, arguing with zeal among themselves, all of them mutually recognized. In this mutual recognition of the church hierarchy, there was a connection between the two churches, which already differed considerably in their spirit.
