Byzantine Catholic Metropolitan Church of Pittsburgh

The Byzantine Catholic Metropolia of Pittsburgh (Latin: Pittsburgensis ritus byzantini) is part of the Ruthenian 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 a 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.
