The Roman and Eastern Catholic Churches in North America and Central America comprise 14 episcopal conferences, which together include 100 ecclesiastical provinces, each of which is headed by a metropolitan archbishop. The provinces are in turn subdivided into 85 archdioceses, 400 non-archdiocesan dioceses and 15 territorial prelatures, each of which is headed by a bishop or an archbishop (metropolitan if he has one or more suffragans). Some episcopal conferences include Military ordinariate (quasi dioceses), personal ordinariates and Eastern Catholic eparchies and/or exarchates that may not be part of an ecclesiastical province.
The Ukrainian Catholic Metropolitan Province of Philadelphia consists of four eparchies of the Ukrainian Greek Catholic Church, and covers the entire United States.
The Byzantine Catholic Metropolitan Province of Pittsburgh is a sui iuris metropolia, traditionally linked to the Ruthenian Greek Catholic Church. The metropolia consists of four eparchies of the Byzantine Rite Ruthenian Catholic Church and covers the entire United States, with jurisdiction for all Ruthenian Catholics in the United States, as well as other Byzantine Rite Catholics without an established hierarchy in the country.
The other Eastern Catholic Churches with eparchies (dioceses) or exarchates established in the United States are not grouped into metropoliae. All are immediately subject to the Holy See, with limited oversight by the head of their respective sui iuris church.
An apostolic administration in the Catholic Church is administrated by a prelate appointed by the pope to serve as the ordinary for a specific area. Either the area is not yet a diocese, or is a diocese, archdiocese, eparchy or similar permanent ordinariate that either has no bishop or archbishop or, in very rare cases, has an incapacitated (arch)bishop. The title also applies to an outgoing (arch)bishop while awaiting for the date of assuming his new position.
The Metropolis of Pittsburgh is a sui juris metropolitan see of the Ruthenian Greek Catholic Church that is located in the United States of America and Canada. The Ruthenian Greek Catholic Church is one of 23 sui juris Eastern Catholic particular churches in the Catholic Church that is in full communion with the Holy See. The metropolis uses the Byzantine Rite in its liturgies. It was erected as a metropolis (archdiocese) by Pope Paul VI in 1969. The metropolis has jurisdiction over those communities that originated from the regions of Carpathian Ruthenia, Slovakia, Hungary and the former Yugoslavia. Worshipers come from several Byzantine Catholic groups: Rusyn Americans, Slovak Americans, Hungarian Americans, and Croatian Americans. In 2022, governance of the Exarchate of Saints Cyril and Methodius of Toronto in Canada passed to the metropolis of Pittsburgh from the Slovak Greek Catholic Church.
The Ukrainian Greek Catholic Archeparchy of Philadelphia is a Ukrainian Greek Catholic Church ecclesiastical territory or archeparchy of the Catholic Church in the Eastern United States. Its episcopal see is Philadelphia, Pennsylvania. The Archeparchy of Philadelphia is a metropolitan see with three suffragan eparchies in its ecclesiastical province. The Archeparchy of Philadelphia's territorial jurisdiction includes the District of Columbia, Virginia, Maryland, New Jersey, and the eastern and central portions of Pennsylvania.
The Hungarian Greek Catholic Church or the Byzantine Catholic Church in Hungary is a sui iuris (autonomous) Eastern Catholic church based in Hungary. As a particular church of the Catholic Church, it is in full communion with the Holy See. Its liturgical usage is that of the Byzantine Rite in the Hungarian language.
The Archeparchy of Pittsburgh is an archeparchy of the Ruthenian Greek Catholic Church that is located in the southern part of the United States of America. It is part of the Metropolis of Pittsburgh. The geographical remit of the archeparchy includes the states of Alabama, Arkansas, Kentucky, Louisiana, Mississippi, Oklahoma, Pennsylvania, Tennessee, Texas, and West Virginia. The incumbent archeparch is the Most Reverend William C. Skurla. The episcopal seat is situated in the city of Pittsburgh.
A particular church is an ecclesiastical community of followers headed by a bishop, as defined by Catholic canon law and ecclesiology. A liturgical rite, a collection of liturgies descending from shared historic or regional context, depends on the particular church the bishop belongs to. Thus the term "particular church" refers to an institution, and "liturgical rite" to its ritual practices.
An ecclesiastical region is a formally organised geographical group of dioceses, ecclesiastical provinces or parishes, without a proper Ordinary as such, in Catholic or Protestant Churches.
