Abstract

In the history of the Christian Church in general, and Ukraine in particular, Orthodox-Catholic relations occupy an extremely important place. The dramatic, as a fact of church and religious life, they attracted the attention of a large number of scholars of different fields of knowledge and research interests. Arsena Rychynsky, a well-known Ukrainian religious scholar whose views on the problem of unity of the Christian Church, overwhelmingly, are scientifically valid, meaningfully original and prognostically relevant. Under such a review, we would like to update some of the researcher's provisions, which directly or indirectly correlate with the uniqueness in her Ukrainian expression. To this end, we recall that, by the exact definition of I. Lysyak-Rudnytsky, Ukraine is quite rightly considered a classic country of the unified tradition. Located on the border of the two worlds, by which we understand the Orthodox East and the Catholic West, it has become the subject of influence of both the Greek and Roman Churches, which, after all, has caused acute religious and religious events in Rus-Ukraine. inter-confessional controversy and repeated attempts at Orthodox-Catholic reconciliation, and even unification.
