摘要：In article relationship of Russian Orthodox Church and Catholic in 1980 – the 1990th years is considered. Dialogue development between them had not only internal political, but also foreign policy value. One of the most painful questions in relationship of Russian Orthodox Church and the question of the uniatsky church earlier existing in the territory of Ukraine and Belarus and restored in the second half of the 1980th years was Catholic. Divergences in a number of theological questions remained. In particular, it belonged to the doctrine confirmed with the Second Vatican Cathedral about Papal infallibility and a primacy of the Roman High priest. Peacekeeping activity was that sphere where the Russian Orthodox and Catholic churches most successfully cooperated though rivalry was present and here.
