Sui iuris in the context of "Latin liturgical rites"

The Latin Church (Latin: Ecclesia Latina) is the largest autonomous (sui iuris) particular church within the Catholic Church, whose members constitute the vast majority of the 1.3 billion Catholics. The Latin Church is one of 24 sui iuris churches in full communion with the pope; the other 23 are collectively referred to as the Eastern Catholic Churches, and they have approximately 18 million members combined.

The Latin Church is directly headed by the pope in his role as the bishop of Rome, whose cathedra as a bishop is located in the Archbasilica of Saint John Lateran in Rome, Italy. The Latin Church both developed within and strongly influenced Western culture; as such, it is sometimes called the Western Church (Latin: Ecclesia Occidentalis), which is reflected in one of the pope's traditional titles in some eras and contexts, the Patriarch of the West. It is also known as the Roman Church (Latin: Ecclesia Romana), the Latin Catholic Church, and in some contexts as the Roman Catholic Church (though this name can also refer to the Catholic Church as a whole).

The Eastern Catholic Churches or Oriental Catholic Churches, also known as the Eastern-Rite Catholic Churches, Eastern Rite Catholicism, or simply the Eastern Churches, are 23 Eastern Christian autonomous (sui iuris) particular churches of the Catholic Church in full communion with the pope in Rome. Although they are distinct theologically, liturgically, and historically from the Latin Church, they are all in full communion with it and with each other. Eastern Catholics are a minority within the Catholic Church; of the 1.3 billion Catholics in communion with the pope, approximately 18 million are members of the Eastern churches. The largest numbers of Eastern Catholics are found in Eastern Europe, Eastern Africa, the Middle East, and India. As of 2022, the Syro-Malabar Church is the largest Eastern Catholic Church, followed by the Ukrainian Greek Catholic Church.

With the exception of the Maronite Church, the Eastern Catholic Churches are groups that, at different points in the past, used to belong to the Eastern Orthodox Church, the Oriental Orthodox churches, or the Church of the East; these churches underwent various schisms through history. Eastern Catholic Churches that were formerly part of other communions have been points of controversy in ecumenical relations with the Eastern Orthodox and other non-Catholic churches. The five historic liturgical traditions of Eastern Christianity, namely the Alexandrian Rite, the Armenian Rite, the Byzantine Rite, the East Syriac Rite, and the West Syriac Rite, are all represented within Eastern Catholic liturgy. On occasion, this leads to a conflation of the liturgical word "rite" and the institutional word "church". Some Eastern Catholic jurisdictions admit members of churches not in communion with Rome to the Eucharist and the other sacraments.

The Roman Rite (Latin: Rītus Rōmānus) is the most common ritual family for performing the ecclesiastical services of the Latin Church, the largest of the sui iuris particular churches that comprise the Catholic Church. The Roman Rite governs rites such as the Roman Mass and the Liturgy of the Hours as well as the manner in which sacraments and blessings are performed.

The Roman Rite developed in the Latin language in the city of Rome and, while distinct Latin liturgical rites such as the Ambrosian Rite remain, the Roman Rite has gradually been adopted almost everywhere in the Latin Church. In medieval times there were numerous local variants, even if all of them did not amount to distinct rites, yet uniformity increased as a result of the invention of printing and in obedience to the decrees of the Council of Trent of 1545–1563 (see Quo primum). Several Latin liturgical rites which had survived into the 20th century were abandoned after the Second Vatican Council. The Roman Rite is now the most widespread liturgical rite not only in the Catholic Church but in Christianity as a whole.

The Eastern Catholic Churches of the Catholic Church utilize liturgies originating in Eastern Christianity, distinguishing them from the majority of Catholic liturgies which are celebrated according to the Latin liturgical rites of the Latin Church. While some of these sui iuris churches use the same liturgical ritual families as other Eastern Catholic churches and Eastern churches not in full communion with Rome, each church retains the right to institute its own canonical norms, liturgical books, and practices for the ritual celebration of the Eucharist, other sacraments, and canonical hours.

Historically, tension between Latin Catholics and those worshipping with Eastern liturgies resulted in the latinization, restriction, or prohibition of Eastern liturgies within the Catholic Church. Since the early 20th century, popes have encouraged the usage of traditional liturgies among Eastern Catholics and delatinization. Further emphasis on Eastern Catholic liturgical practice was made during the Second Vatican Council with the publication of the 1964 Orientalium Ecclesiarum.

Adoption in ancient Rome was primarily a legal procedure for transferring paternal power (potestas) to ensure succession in the male line within Roman patriarchal society. The Latin word adoptio refers broadly to "adoption", which was of two kinds: the transferral of potestas over a free person from one head of household to another; and adrogatio, when the adoptee had been acting sui iuris as a legal adult but assumed the status of unemancipated son for purposes of inheritance. Adoptio was a longstanding part of Roman family law pertaining to paternal responsibilities such as perpetuating the value of the family estate and ancestral rites (sacra), which were concerns of the Roman property-owning classes and cultural elite. During the Principate, adoption became a way to ensure imperial succession.

In contrast to modern adoption, Roman adoptio was neither designed nor intended to build emotionally satisfying families and support childrearing. Among all social classes, childless couples or those who wanted to expand the size of their families instead might foster children. Evidence is meager for the adoptio of young children for purposes other than securing a male heir, and probably would have been employed mostly by former slaves legitimating the status of their own children born into slavery or outside a legally valid marriage.

The Greek Byzantine Catholic Church (Greek: Ελληνόρρυθμη Καθολική Εκκλησία, Ellinórrythmi Katholikí Ekklisía) or the Greek-Catholic Church of Greece is a sui iuris Eastern Catholic particular church of the Catholic Church that uses the Byzantine Rite in Koine Greek and Modern Greek. Its membership includes inhabitants of Greece and Turkey, with some links with Italy and Corsica.

Maronites (Arabic: الموارنة, romanized: Al-Mawārinah; Syriac: ܡܖ̈ܘܢܝܐ, romanized: Mārōnōye) are a Syriac Christian ethnoreligious group native to the Eastern Mediterranean and the Levant (particularly Lebanon) whose members belong to the Maronite Church. The largest concentration has traditionally resided near Mount Lebanon in modern Lebanon. The Maronite Church is an Eastern Catholic sui iuris particular church in full communion with the pope and the rest of the Catholic Church.

The Maronites derive their name from Saint Maron, (350-410 AD.), a monk whose teachings spread throughout the Northern Levant becoming the basis of the Maronite tradition. The spread of Christianity was very slow in the Lebanese region; in the 5th century AD in the highlands they were still pagan. St. Maron sent the apostle Abraham of Cyrrhus known as the "Apostle of Lebanon" with a mandate to convert the pagan inhabitants of Mount Lebanon to Christianity. After their conversion, the inhabitants of the region renamed the Adonis River to the Abrahamic River in honor of the Saint who preached there.
