Currently, the Ukrainian GreekCatholic Church is the dominant faith in several western oblasts of Ukraine, and although spread throughout the country, is a small minority elsewhere.
The foundation of the Ukrainian Catholic Church was laid by the communion of the Patriarch of Constantinople with the Popes in Rome throughout most of the first millennium (until 1054) and intermittent communion thereafter.
The Catholicity of the Ukrainian Church was confirmed by the resistance of the hierarchs of Rus' minora, or Rus' proper (today's Ukraine) to the requests of the Greek Church at Constantinople to break communion with Rome after the Great Schism of 1054.
Catholics of the Byzantine rite, known as GreekCatholics, are heirs of the Union of Brest of 1596, which the hierarchy of the Kyivan Metropolia established with the Church of Rome.
Regardless of the fact that it was officially forbidden and harshly persecuted, this Church preserved its hierarchical structures in the underground and diaspora, and in December 1989 it requested official legalization.
Catholics of the Latin rite are members of the Roman Catholic Church (RCC) in Ukraine, whose hierarchical structures in the past were spread over those Ukrainian lands which became incorporated into neighboring Catholic nations.
