Sui juris in the context of "Italo-Albanian Greek Catholic 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.

In the Eastern Catholic Churches, major archbishop (sometimes also styled as major archeparch) is a title for the chief hierarch ("Father and Head") of an autonomous (sui juris) particular Church that has not been "endowed with the patriarchal title". Major archbishops generally have the same rights, privileges, and jurisdiction as Eastern Catholic patriarchs, except where expressly provided otherwise, and rank immediately after them in precedence of honor.

In addition to their role governing their particular Church, major archbishops, like Eastern Catholic patriarchs, are ex officio members of the Congregation for the Oriental Churches in the Roman Curia. They are required to attend the annual general meeting of this congregation, as well as other sessions if they are visiting Rome or are otherwise able.

The Syro-Malabar Church, also known as the Syro-Malabar Catholic Church / Edta Qatholiqi D’Malabar Suryaya,Syriac: ܥܸܕܬܵܐ ܩܵܬܘܿܠܝܼܩܝܼ ܕܡܲܠܲܒܵܪ ܣܘܼܪܝܵܝܵܐ (or ܥܸܕܬܵܐ ܕܡܲܠܲܒܵܪ ܣܘܼܪܝܵܝܵܐ); Malayalam: സുറിയാനി മലബാർ സഭ is an Eastern Catholic church based in Kerala, India. It is a sui iuris (autonomous) particular church in full communion with the Holy See and the worldwide Catholic Church, with self-governance under the Code of Canons of the Eastern Churches (CCEO). The major archbishop presides over the entire church. The incumbent Major Archbishop is Raphael Thattil, serving since January 2024. It is the largest Syriac Christian church and the largest Eastern Catholic church. Syro-Malabar is a prefix reflecting the church's use of the East Syriac liturgy and origins in Malabar (modern Kerala and parts of Tamil Nadu). The name has been in usage in official Vatican documents since the nineteenth century.

The Syro-Malabar Church is primarily based in India; with five metropolitan archeparchies and ten suffragan eparchies in Kerala, there are 4 Archeparchies and 13 eparchies in other parts of India, and four eparchies outside India. The Syro-Malabar Synod of Bishops canonically convoked and presided over by the major archbishop constitutes the supreme authority of the church. The Major Archiepiscopal Curia of the church is based in Kakkanad, Kochi. It is the largest among Saint Thomas Christians communities, with a population of 2.35 million in Kerala as per the 2011 Kerala state census and 4.53 million worldwide as estimated in the 2023 Annuario Pontificio. It is the second largest sui juris church within the communion of the Catholic Church after the Latin Church.

The Eastern Catholic canon law is the law of the 23 Catholic sui juris (autonomous) particular churches of the Eastern Catholic tradition. Eastern Catholic canon law includes both the common tradition among all Eastern Catholic Churches, now chiefly contained in the Code of Canons of the Eastern Churches, as well as the particular law proper to each individual sui juris particular Eastern Catholic Church. Oriental canon law is distinguished from Latin canon law, which developed along a separate line in the remnants of the Western Roman Empire, and is now chiefly codified in the 1983 Code of Canon Law.

This is a list of leaders of the Ukrainian Greek Catholic Church (formerly known as the Ruthenian Uniate Church or the Uniate Church) which is a sui juris (particular church) of the Catholic Church that is in full communion with the Holy See. As an Eastern Catholic church, it uses the Byzantine rite in the Church slavonic and Ukrainian languages in its liturgies. Leaders have held several titles over the centuries. The modern primate of the church holds the position of a major archeparch (also styled as "major archbishop").

Due to historical circumstances (i.e. Russian occupation), the first hierarchs of the Ukrainian Greek Catholic Church held titles that did not mention the original metropolitan city of Kyiv. It is common for people to refer to the major archbishop as a "Primate". However, only Mykhailo Levitsky officially held that title which was granted by the Austrian Emperor as the Primate of Halychyna and Lodomeria, but not approved by the Pope.
