Ecclesiastical province in the context of "Archdiocese"

Eparchy (Greek: ἐπαρχία eparchía "overlordship") is an ecclesiastical unit in Eastern Christianity that is equivalent to a diocese in Western Christianity. An eparchy is governed by an eparch, who is a bishop. Depending on the administrative structure of a specific Eastern Church, an eparchy can belong to an ecclesiastical province (usually a metropolis), but it can also be exempt. Each eparchy is divided into parishes, in the same manner as a diocese in Western Churches. Historical development of eparchies in various Eastern Churches was marked by local distinctions that can be observed in modern ecclesiastical practices of the Eastern Orthodox Church, Oriental Orthodox Churches and Eastern Catholic Churches.

The Diocese of Rome (Latin: Dioecesis Urbis seu Romana; Italian: Diocesi di Roma) is a Latin diocese of the Catholic Church under the direct jurisdiction of the pope, who is Bishop of Rome and hence the supreme pontiff and head of the worldwide Catholic Church. As the Holy See, the papacy is a sovereign entity with diplomatic relations, and it has civil jurisdiction over Vatican City (located geographically within the city of Rome). The Diocese of Rome consists of two geographical jurisdictions: the Vicariate of Rome, and the small Vicariate of Vatican City. It is the metropolitan diocese of the Province of Rome, an ecclesiastical province in the Ecclesiastical Region of Lazio in Italy. According to Catholic tradition, the first bishop of Rome was Saint Peter during the first century.

Historically, many Rome-born men – as well as others born elsewhere on the Italian peninsula – served as bishops of Rome. Since 1900, however, there has been only one Rome-born bishop of Rome, Pius XII (1939–1958). In addition, throughout history, non-Italians have served as bishops of Rome, beginning with the first of them according to Catholic tradition – Saint Peter.

A metropolis, metropolitanate or metropolitan diocese is an episcopal see whose bishop is the metropolitan bishop or archbishop of an ecclesiastical province. Metropolises, historically, have been important cities in their provinces.

In Christian denominations, an archbishop is a bishop of higher rank or office. In most cases, such as the Catholic Church, there are many archbishops who either have jurisdiction over an ecclesiastical province in addition to their own archdiocese (with some exceptions), or are otherwise granted a titular archbishopric. In others, such as the Lutheran Church of Sweden, the title is only borne by the leader of the denomination.

Anglicanism, also known as Episcopalianism in some countries, is a Western Christian tradition which developed from the practices, liturgy, and identity of the Church of England following the English Reformation, in the context of the Protestant Reformation in Europe. It is one of the largest branches of Christianity, with around 110 million adherents within the Anglican Communion, and more than 400,000 outside of the Anglican Communion, worldwide as of 2025.

Adherents of Anglicanism are called Anglicans; they are also called Episcopalians in some countries. Most are members of national or regional ecclesiastical provinces of the international Anglican Communion, one of the largest Christian bodies in the world, and the world's third-largest Christian communion. The provinces within the Anglican Communion have historically been in full communion with the See of Canterbury and thus with the archbishop of Canterbury, whom the communion refers to as its primus inter pares (Latin, 'first among equals'). The archbishop calls the decennial Lambeth Conference, chairs the meeting of primates, and is the president of the Anglican Consultative Council. Some churches that are not part of the Anglican Communion or recognised by it also call themselves Anglican, including those that are within the Continuing Anglican movement and Anglican realignment.

The Slovak Greek Catholic Church or Byzantine Catholic Church in Slovakia, is a sui iuris (autonomous) Eastern Catholic church based in Slovakia. As a particular church of the Catholic Church, it is in full communion with the Holy See. The church is organised as a single ecclesiastical province with one metropolitan see. Its liturgical rite is the Byzantine Rite. In 2008 in Slovakia alone, the Greek Catholic Church in Slovakia had some 350,000 faithful, 374 priests and 254 parishes. In 2017, the Catholic Church counted 207,320 Greek Catholics in Slovakia worldwide, representing roughly one percent of all Eastern Catholics.
