Byzantine Catholic Metropolitan Church of Pittsburgh

The Byzantine Catholic Metropolia of Pittsburgh () is part of the Ruthenian Greek Catholic Church (whose members are mostly Rusyns from the Carpathian Mountains, but also Ukrainians, Hungarians, Slovaks, and Croats and their descendants) in the United States.
The Metropolia, which is structured as an ecclesiastical province, itself has four components:
Although Rusyn Americans constitute the majority of members of the Metropolia, the Church has ordinary jurisdiction over the faithful of certain Churches within the Slavic Tradition of the Byzantine Rite that do not have an established hierarchy in the United States, specifically those of the Hungarian, Slovak, and Croatian Greek-Catholic Churches.
When the Ruthenian Catholic Church in Europe was under atheistic Communist rule, and because of persecution, unable to organize publicly, the impossibility of regular communication with it meant that the distant American Metropolia, unable to be treated as a normal metropolia of an Eastern Rite Catholic Church (canons 133–139 of the Code of Canons of the Eastern Churches), has been treated as a sui iuris (autonomous) Metropolitan Church (canons 155–173 of the Code of Canons of the Eastern Churches). The Holy See's "Annuario Pontificio" has, however, always listed it not as a separate particular Church but as a Metropolia of the Ruthenian Church.
History.
The Archeparchy of Pittsburgh was originally established, in 1924, as the Apostolic Exarchate for the Byzantine-Rite Faithful of Subcarpathia, becoming the Eparchy of Pittsburgh of the Ruthenians in 1963, the Metropolitan See of Munhall of the Ruthenians in 1969, and changing its name to Pittsburgh of the Byzantines in 1977. The dates of foundation of the suffragan sees are: Passaic 1963, Parma 1969, Van Nuys 1981 (moved to Phoenix in 2010).
The church's Byzantine Catholic Seminary of SS. Cyril and Methodius, established in 1950, is located on Pittsburgh, Pennsylvania's Observatory Hill. In addition to the training of priests, it offers a program in Deacon Formation as well as a Cantor's Institute.
In January 2007 Metropolitan Basil Schott, Archbishop of Pittsburgh promulgated a major revision of two of the major Divine Liturgies (Chrysostom and Basil) of the Byzantine Catholic Church.
