Editor’s Note: There is an intense religious war being waged by the Russian orthodox against the Ukrainian orthodox, evidenced in this report. Priceless originals of Ukrainian liturgical texts were burnt by Russian Orthodox representatives. Even the icons will be torn down.
The Catholic Faith came to Ukraine in the 10th century. All the founding saints were Catholics. The Greeks won the Ukrainians over to their schism following the sacking of Constantinople in 1204 A. D.. However, the sacred hierarchy was established in this land by apostolic succession c. 1040 A. D., and returned to communion with Rome after the Council of Florence in 1449 A. D., a renunion which lasted for some decades.
However, Moscow declared itself a Patriarch in 1589 A. D., in violation of all sacred canons, which restricted this dignity to the Four Sees where St. Peter had preached: Rome, Jerusalem, Antioch, Alexandria and to Constantinople.
