Patriarch in the context of "Bishops in the Catholic Church"

Patriarchate (/ˈpeɪtriɑːrkɪt, -keɪt/, UK also /ˈpætri-/; Ancient Greek: πατριαρχεῖον, patriarcheîon) is an ecclesiological term in Christianity, referring to the office and jurisdiction of a patriarch.

According to Christian tradition, three patriarchates—Rome, Antioch, and Alexandria—were established by the apostles as apostolic sees in the 1st century. These were officially recognized by the First Council of Nicaea. The Patriarchate of Constantinople was added in the 4th century, and the Patriarchate of Jerusalem followed in the 5th century. These five sees were later recognized collectively as the pentarchy by the Council of Chalcedon in 451.

Pentarchy (from Ancient Greek Πενταρχία (Pentarchía), from πέντε (pénte) 'five' and ἄρχειν (archein) 'to rule') was a model of Church organization formulated in the laws of Emperor Justinian I (r.  527–565) of the Roman Empire. In this model, the Christian Church is governed by the heads (patriarchs) of the five major episcopal sees of the Roman Empire: Rome, Constantinople, Alexandria, Antioch, and Jerusalem.

The idea came about because of the political and ecclesiastical prominence of these five sees, but the concept of their universal and exclusive authority was attached to earlier Hellenistic-Christian ideas of administration. The pentarchy was first legally expressed in the legislation of Emperor Justinian I, particularly in Novella 131. The Quinisext Council of 692 gave it formal recognition and ranked the sees in order of preeminence, but its organization remained dependent on the emperor, as when Leo the Isaurian altered the boundary of patriarchal jurisdiction between Rome and Constantinople. Especially following Quinisext, the pentarchy was at least philosophically accepted in Eastern Orthodoxy, but in the West, the Rome based patriarchy evolved into the Roman Catholic Church, which would reject the Council as well as the concept of the pentarchy, considering itself the supreme church with universal jurisdiction.

The Eastern Orthodox Church, officially the Orthodox Catholic Church and commonly known simply as the Orthodox Church, is a communion composed of up to seventeen separate autocephalous (self-governing) hierarchical churches that profess Eastern Orthodoxy and recognise each other as canonical (regular) Eastern Orthodox Christian churches.

Each constituent church is self-governing; its highest-ranking bishop called the primate (a patriarch, a metropolitan or an archbishop) reports to no higher authority. Each regional church is composed of constituent eparchies (or dioceses) ruled by bishops. Some autocephalous churches have given an eparchy or group of eparchies with varying degrees of autonomy (meaning they have limited self-government). Such autonomous churches maintain varying levels of dependence on their mother church, usually defined in a tomos or another document of autonomy. In many cases, autonomous churches are almost completely self-governing, with the mother church retaining only the right to appoint the highest-ranking bishop (often an archbishop or metropolitan) of the autonomous church.

The Catholic Church is "the Catholic Communion of Churches, both Roman and Eastern, or Oriental, that are in full communion with the Bishop of Rome (the pope)." This communion comprises the Latin Church (the Roman or Western Church) as well as 23 Eastern Catholic Churches, canonically called sui juris churches, each led by either a patriarch or a major archbishop in full communion with the pope. Historically, these bodies separated from Eastern Christian communions, either to remain in or to return to full communion with the Catholic Church. The Vatican II decree on Eastern Catholic Churches, however, explicitly recognizes them as churches and not just rites within the Catholic Church. This communion "exists among and between the individual Churches and dioceses of the universal Catholic Church. Its structural expression is the College of Bishops, each of whom represents and embodies his own local church." In addition to Eastern Catholic Churches, the Catholic Church oversees the Catholic Charismatic Renewal, the largest Charismatic movement of a single institution in 2020, with over 100 million members, primarily in the Global South. The Catholic Church is also described as an "amalgam of parts" (i.e., thousands of individual dioceses and religious orders) globally dispersed, but in communion with Rome.

The Catholic Church is the "world's oldest continuously functioning international institution." It is also the largest non-government provider of education and health care in the world, while the diplomatic status of the Holy See facilitates access to its vast international network of charities. These entities include 5,000 hospitals, 10,000 orphanages, 95,000 elementary schools and 47,000 secondary schools.

A cadet branch consists of the male-line descendants of a monarch's, ruler's or patriarch's younger sons (cadets). In the ruling dynasties and noble families of much of Europe and Asia, the family's major assets (realm, titles, fiefs, properties, lands and income) have historically been passed from the father to his firstborn son in what is known as primogeniture; younger sons, the cadets, generally inherited less wealth and authority (such as a small appanage) to pass on to future generations of their descendants.

In families and cultures in which that was not the custom or law, such as the feudal Holy Roman Empire, the equal distribution of the family's holdings among male members was eventually apt to so fragment the inheritance as to render it too small to sustain the descendants at the socio-economic level of their forefather—and indeed, too small to efficiently manage or effectively defend. Moreover, brothers and their descendants sometimes quarreled over their allocations, or even became estranged. While agnatic primogeniture became a common way of keeping the family's wealth intact and reducing familial disputes, it did so at the expense of younger sons and their descendants. Both before and after a state legal default of inheritance by primogeniture, younger brothers sometimes vied with older brothers to be chosen as their father's heir or, after the choice was made, sought to usurp the elder's birthright.

The Patriarch of All Bulgaria (Bulgarian: Патриарх Български) is the patriarch of the Bulgarian Orthodox Church. The patriarch is officially styled as Patriarch of All Bulgaria and Metropolitan of Sofia. The current patriarch Daniil acceded to this position on 30 June 2024.

The Ethiopian Orthodox Tewahedo Church (Amharic: የኢትዮጵያ ኦርቶዶክስ ተዋሕዶ ቤተ ክርስቲያን, romanized: Yä-ityopp'ya ortodoks täwahədo betä krəstiyan) is the largest of the Oriental Orthodox Churches. One of the few Christian churches in Africa originating before European colonization of the continent, the Ethiopian Orthodox Tewahedo Church dates back to the Christianization of the Kingdom of Aksum in 330, and has between 38 million and 46 million adherents in Ethiopia. The Ethiopian Orthodox Tewahedo Church claims 60 million members worldwide. It is a founding member of the World Council of Churches. The Ethiopian Orthodox Tewahedo Church is in communion with the other Oriental Orthodox churches (the Eritrean Orthodox Tewahedo Church, the Coptic Orthodox Church of Alexandria, the Malankara Orthodox Syrian Church, the Armenian Apostolic Church, and the Syriac Orthodox Church).

The Ethiopian Orthodox Tewahedo Church had been administratively part of the Coptic Orthodox Church of Alexandria from the first half of the 4th century until 1959, when it was granted autocephaly with its own patriarch by Pope Cyril VI of Alexandria, Pope of the Coptic Orthodox Church.

The Patriarch of Alexandria is the archbishop of Alexandria, Egypt. Historically, this office has included the designation "pope" (etymologically "Father", like "Abbot").

The Alexandrian episcopate was revered as one of the three major episcopal sees (along with Rome and Antioch) before Constantinople and Jerusalem were granted similar status (in 381 and 451, respectively). Alexandria was elevated to de facto archiepiscopal status by the Councils of Alexandria, and this status was ratified by Canon Six of the First Council of Nicaea, which stipulated that all the Egyptian episcopal provinces were subject to the metropolitan see of Alexandria. In the sixth century, these five archbishops were formally granted the title of "patriarch" and were subsequently known as the Pentarchy.

The Maphrian (Syriac: ܡܦܪܝܢܐ, romanized: maphryānā or maphryono), is the second-highest rank in the ecclesiastical hierarchy of the Syriac Orthodox Church, right below that of patriarch. The office of a maphrian is a maphrianate. There have been three maphrianates in the history of the Syriac Orthodox Church and one, briefly, in the Syriac Catholic Church.

The first maphrianate, called the Maphrianate of the East or the Maphrianate of Tagrit, was established in 628 to give the Syriac Orthodox Church an ecclesiastical hierarchy in the Sasanian Empire and lands outside the control of the Roman Empire. The seat of the bishop was initially at Tagrit and he ranked second in the hierarchy after the Patriarch of Antioch. Initially he used the title catholicos in direct opposition to the rival Catholicos of Seleucia-Ctesiphon of the Church of the East. The title "maphrian" first came into use around 1100. In 1156 the seat of the maphrian was moved to Mosul. The Maphrianate of the East was abolished in 1860 as a result of a decreasing number of Syriac Orthodox outside of the region of Ṭur ʿAbdin. By then it had been a merely titular see for a long time.
