This week Toronto hosts the head of the largest of the Eastern Catholic Churches, Sviatoslav Shevchuk of the Ukrainian Greek Catholic Church (UGCC). Within the UGCC, Shevchuk is referred to as the Patriarch of Kyiv, the common title for the head of an Eastern Catholic Church. Due to tensions with the Orthodox though, especially in Russia, the Holy See grants him the title of “major archbishop,” equivalent in all aspects to a patriarch.
