Eastern Catholics in the context of "Armenian Rite"

Rusyns, also known as Carpatho-Rusyns, Carpatho-Russians, Ruthenians, or Rusnaks, are an East Slavic ethnic group from the Eastern Carpathians in Central and Eastern Europe. They speak Rusyn, an East Slavic language variety, treated variously as either a distinct language or a dialect of the Ukrainian language. As traditional adherents of Eastern Christianity, the majority of Rusyns are Eastern Catholics, though a minority of Rusyns practice Eastern Orthodoxy.

Rusyns primarily self-identify as a distinct ethnic group and are recognized as such in all countries where they exist, with the exception of Ukraine, which officially classifies Rusyns as a sub-group of Ukrainians. In Croatia, Hungary, Poland, Romania, Serbia, and Slovakia, Rusyns have official minority status. Some Rusyns identify more closely with their country of residence (e.g. Polish, Slovak), while others self-identify as a branch of the Ukrainian people.

The Latin Patriarchate of Jerusalem (Latin: Patriarchatus Latinus Hierosolymitanus) is the Latin Catholic ecclesiastical patriarchate in Jerusalem, officially seated in the Church of the Holy Sepulchre. The Latin patriarch of Jerusalem is the archbishop of Latin Church Catholics of the Archdiocese of Jerusalem with jurisdiction for all Latin Catholics in Israel, Palestine, Jordan and Cyprus; he also holds the office of grand prior of the Order of the Holy Sepulchre. It is exempt, being directly subject to the Holy See (and exceptionally its Dicastery for the Eastern Churches, which normally handles Eastern Catholics). It is not within an ecclesiastical province, and has no metropolitan functions.

The Patriarchate was originally established in 1099, with the Kingdom of Jerusalem encompassing the territories in the Holy Land newly conquered by the First Crusade. From 1374 to 1847 it was a titular see, with the patriarchs of Jerusalem being based at the Basilica di San Lorenzo fuori le Mura in Rome. Pope Pius IX re-established a resident Latin patriarch in 1847.

The Dicastery for Bishops, formerly named Congregation for Bishops (Latin: Congregatio pro Episcopis), is the department of the Roman Curia of the Catholic Church that oversees the selection of most new bishops. Its proposals require papal approval to take effect, but are usually followed. The Dicastery also schedules the visits at five-year intervals ("ad limina") that bishops are required to make to Rome, when they meet with the pope and various departments of the Curia. It also manages the formation of new dioceses. It is one of the more influential Dicasteries, since it strongly influences the human resources policy of the church.

The jurisdiction of the Dicastery does not extend to mission territories, under the Dicastery for Evangelization, or areas managed by the Dicastery for the Eastern Churches (which has responsibility for all Eastern Catholics, and for Latin Catholics in the Middle East and Greece). Where appointment of bishops and changes in diocesan boundaries require consultation with civil governments, the Secretariat of State has primary responsibility, but must consult the Dicastery for Bishops. The Dicastery also have oversight of investigations into allegations of abuse and negligence by bishops.

The Apostolic Vicariate of Beirut (Latin: Vicariatus Apostolicus Berytensis) is a Latin Church ecclesiastical jurisdiction or apostolic vicariate of the Catholic Church in Lebanon, where Eastern Catholics are far more numerous. In 2022, there were about 18,000 Catholics in ten parishes in the Apostolic Vicariate of Beirut. Its current bishop is Cesar Essayan who was appointed in 2016. Its cathedral episcopal see is the St. Louis Cathedral, Beirut in the national capital city Beirut, while the former Crusader Cathedral of Tyre is in ruins.

The Latin Church of the Catholic Church has several dispersed populations of members in the Middle East, notably in Turkey, Cyprus and the Levant (Syria, Lebanon, Palestine and Jordan). Latin Catholics employ the Latin liturgical rites, in contrast to Eastern Catholics who fall under their respective church's patriarchs and employ distinct Eastern Catholic liturgies, while being in full communion with the worldwide Catholic Church.

Depending on the specific area in question, due to their cultural heritage descending from Catholics who lived under the Ottoman Empire, they are sometimes referred to as Levantines, Italo-Levantines  (it), or Franco-Levantines (Arabic: شوام; French: Levantins; Italian: Levantini; Greek: Φραγκολεβαντίνοι Frankolevantini; Turkish: Levantenler or Tatlısu Frenkleri) after Frankokratia.
