Catholic Church

The Maronite Church (Arabic: الكنيسة المارونية‎; Syriac: ܥܕܬܐ ܣܘܪܝܝܬܐ ܡܪܘܢܝܬܐ) is an Eastern Catholic sui iuris particular church in full communion with the pope and the worldwide Catholic Church, with self-governance under the Code of Canons of the Eastern Churches. The head of the Maronite Church is Patriarch Bechara Boutros al-Rahi, who was elected in March 2011 following the resignation of Patriarch Nasrallah Boutros Sfeir. The seat of the Maronite Patriarchate is in Bkerké, northeast of Beirut, Lebanon. Officially known as the Antiochene Syriac Maronite Church (Arabic: الكنيسة الأنطاكية السريانية المارونية; Syriac: ܥܹܕܬܵܐ ܣܘܪܝܝܐ ܡܪܘܝܝܐ ܐܢܛܝܘܟܝܐ), it is part of Syriac Christianity by liturgy and tradition.

The early development of the Maronite Church can be divided into three periods, from the 4th to the 7th centuries. A congregation movement, with Saint Maron from the Taurus Mountains as an inspirational leader and patron saint, marked the first period. The second began with the establishment of the Monastery of Saint Maroun on the Orontes, built after the Council of Chalcedon to defend the doctrines of the council. This monastery was described as the "greatest monastery" in the region of Syria Secunda, with more than 300 hermitages around it, according to ancient records. After 518, the monastery de facto administered many parishes in Syria Prima, Cole Syria and Phoenicia. The third period was when Sede Vacante followed the Islamic conquest of the region and bishops of the Saint Maron Monastery elected John Maron as Patriarch circa 685 AD, according to Maronite tradition. The Greek Orthodox Church of Antioch reestablished their patriarchate in 751 AD. Other centers of historical importance include Kfarhay, Yanouh, Mayfouq, and the Qadisha Valley.

The Catholic Church and Eastern Orthodox Church broke communion during the East–West Schism of 1054. While an informal divide between the East and West existed prior to the split, these were internal disputes, under the umbrella of the recognised “one, holy, catholic and apostolic Church” of the Nicene Creed. It is only after the formal schism of the 11th century that two, distinct churches are seen to exist, and thus commence relations. The split has, on both sides, been immensely lamented, for it defeats the exhortation of Jesus Christ “that they may all be one" (John 17:21). The anguish over the past has spurred both sides, particularly in recent decades, to work towards restoring Christian unity through ecumenical efforts.

Relations between the East and West have warmed over the last century, as both churches embrace a dialogue of charity. The Second Vatican Council (1962–1965) ushered in a new era of relations for the Roman Church towards the Orthodox Church, fondly describing the Orthodox as “separated brethren” with valid sacraments and an apostolic priesthood. The Orthodox Church, on the other hand, encouraged local churches to prepare for future dialogue in the Third Pan-Orthodox Conference in Rhodes (1964), and has since engaged in several ecumenical efforts with the Vatican. Significantly, in 1965 Pope Paul VI and Ecumenical Patriarch Athenagoras I of Constantinople jointly lifted the mutual excommunications of 1054. More recently, in November 2019, the current Patriarch of Constantinople, Patriarch Bartholomew, has stated he believes Orthodox re-union with the Catholic Church is inevitable.

The Armenian Rite (Armenian: Հայկական պատարագ) is a liturgical rite used by both the Armenian Apostolic and the Armenian Catholic churches. Isaac of Armenia, the Catholicos of All Armenians, initiated a series of reforms with help from Mesrop Mashtots in the 5th century that distinguished Armenia from its Greek and Syriac counterparts. These reforms included a retranslation of the Bible and a revised liturgy. During the Crusades and afterwards, missionary activity by the Latin Church influenced liturgical norms and induced some Armenians to join the Catholic Church. The modern Armenian Rite features elements and interpolations from the Byzantine Rite and Latin liturgical rites, with the celebration of the Eucharist emulating the Liturgy of Saint Basil.

An apostolic vicariate is a territorial jurisdiction of the Catholic Church under a titular bishop centered in missionary regions and countries where dioceses or parishes have not yet been established. The status of apostolic vicariate is often a promotion for a former apostolic prefecture, while either may have started out as a mission sui iuris. It is essentially provisional, though it may last for a century or more. The hope is that the region will generate sufficient numbers of Catholics for the Church to create a diocese one day.

It is exempt under canon law, directly subject to the missionary Dicastery for Evangelization of the Vatican in Rome. Like the stage of apostolic prefecture which often precedes it, the vicariate is not part of an ecclesiastical province. It is intended to mature in developing Catholic members until it can be promoted to a (usually suffragan) diocese.

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 (a stable 'pre-diocesan', usually missionary apostolic administration), or is a diocese, archdiocese, eparchy or similar permanent ordinariate (such as a territorial prelature or a territorial abbacy) that has no bishop or archbishop (an apostolic administrator sede vacante, as after an episcopal death, resignation or transfer to another territory) or, in very rare cases, has an incapacitated head (apostolic administrator sede plena). The title also applies to an outgoing incumbent while awaiting for the date of assuming his new position or date of effectivity of a retirement.

An apostolic prefect or prefect apostolic is a priest who heads what is known as an apostolic prefecture, a 'pre-diocesan' missionary jurisdiction where the Catholic Church is not yet sufficiently developed to have it made a diocese. Although it usually has an (embryonal) see, it is often not called after such city but rather after a natural feature, or administrative geographical area, which may be a name in use by the local inhabitants, or one assigned by a colonial authority, depending on the circumstances under which the prefecture was established.

If a prefecture grows and flourishes, it may be elevated to an apostolic vicariate, headed by a titular bishop, in the hope that with time the region will generate enough Catholics and stability for its Catholic institutions, to warrant being established as a diocese. Both these stages remain missionary, hence exempt, that is, directly subject to the Holy See, specifically the Dicastery for Evangelization, rather than, as a diocese normally would, belong to an ecclesiastical province.

A military ordinariate is an ecclesiastical jurisdiction of the Catholic Church, of the Latin or an Eastern church, responsible for the pastoral care of Catholics serving in the armed forces of a nation.

Until 1986, they were called "military vicariates" and had a status similar to that of apostolic vicariates, which are headed by a bishop who receives his authority by delegation from the Pope. The apostolic constitution Spirituali militum curae of 21 April 1986 raised their status, declaring that the bishop who heads one of them is an "ordinary", holding authority by virtue of his office, and not by delegation from another person in authority. It likened the military vicariates to dioceses. Each of them is headed by a bishop, who may have the personal rank of archbishop. If the bishop is a diocesan, he is likely to delegate the daily functions to an auxiliary bishop or a lower cleric.

A personal ordinariate for former Anglicans, shortened as personal ordinariate or Anglican ordinariate, is a canonical structure within the Catholic Church established in order to enable "groups of Anglicans" and Methodists to join the Catholic Church while preserving elements of their liturgical and spiritual patrimony.

Created in accordance with the apostolic constitution Anglicanorum coetibus of 4 November 2009 and its complementary norms, the ordinariates are juridically equivalent to a diocese, "a particular church in which and from which exists the one and unique Catholic Church", but may be erected in the same territory as other dioceses "by reason of the rite of the faithful or some similar reason".

A personal prelature is an institution of the Catholic Church which comprises clergy, and optionally laity, under the jurisdiction of a prelate, which undertakes specific pastoral activities. Along with dioceses, and later military ordinariates, personal prelatures were originally under care of the Vatican's Congregation for Bishops, but since 4 August 2022, personal prelatures have been placed under care of the Dicastery for the Clergy. Unlike dioceses, which cover territories for the ordinary pastoral care of the faithful, personal prelatures minister to persons according to some specific pastoral goals, regardless of where they live.The first personal prelature is Opus Dei.

A territorial abbey (or territorial abbacy) is a particular church of the Catholic Church comprising defined territory which is not part of a diocese but surrounds an abbey or monastery whose abbot or superior functions as ordinary for all Catholics and parishes in the territory. Such an abbot is called a territorial abbot or abbot nullius diœceseos (abbreviated abbot nullius and Latin for "abbot of no diocese"). A territorial abbot thus differs from an ordinary abbot, who exercises authority only within the monastery's walls or to monks or canons who have taken their vows there. A territorial abbot is equivalent to a diocesan bishop in Catholic canon law.

While most belong to the Latin Church, and usually to the Benedictine or Cistercian Orders, there is one Eastern Catholic territorial abbey: the Italo-Albanian Greek Catholic Abbey of Grottaferrata. The closest equivalent in the Eastern Orthodox Church would be a stauropegion (e.g. most famously, Mount Athos).
