Ritual family in the context of "Rite (Christianity)"

A particular church (Latin: ecclesia particularis) is an ecclesiastical community of followers headed by a bishop (or equivalent), as defined by Catholic canon law and ecclesiology. A liturgical rite, a collection of liturgies descending from shared historic or regional context, depends on the particular church the bishop (or equivalent) belongs to. Thus the term "particular church" refers to an institution, and "liturgical rite" to its ritual practices.

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.

Latin liturgical rites, or Western liturgical rites, is a large family of liturgical rites and uses of public worship employed by the Latin Church, the largest particular church sui iuris of the Catholic Church, that originated in Europe where the Latin language once dominated and further by Western Rite Orthodoxy and Independent and Old Catholicism. Its language is now known as Ecclesiastical Latin. The most used rite is the Roman Rite.

The Latin rites were for many centuries no less numerous than the modern Eastern Catholic liturgical rites. The number of Latin rites and uses is now much reduced. In the aftermath of the Council of Trent, in 1568 and 1570 Pope Pius V suppressed the breviaries and missals that could not be shown to have an antiquity of at least two centuries in favor of the Roman Missal and Roman Breviary. Many local rites that remained legitimate even after this decree were abandoned voluntarily, especially in the 19th century, in favor of the Tridentine Mass and other Roman Rite rituals. In the second half of the 20th century, most of the religious orders that had a distinct liturgical rite chose to adopt in its place the Roman Rite as revised in accordance with the decrees of the Second Vatican Council (see Mass of Paul VI). A few such liturgical rites persist today for the celebration of Mass, since 1965–1970 in revised forms, but the distinct liturgical rites for celebrating the other sacraments have been almost completely abandoned.

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.

Christian liturgy is a pattern for worship used (whether recommended or prescribed) by a Christian congregation or denomination on a regular basis. The term liturgy comes from Greek and means "public work". Within Christianity, liturgies descending from the same region, denomination, or culture are described as ritual families.

When Christians meet for worship, they perform a liturgy (work), offering service to God together. The majority of Christian denominations hold their principal church service on Sunday, the first day of the week, which is known as the Lord's Day. In some Christian denominations, liturgies are held daily, with these including those in which the canonical hours are prayed, as well as the offering of the Eucharistic liturgies such as Mass, among other forms of worship. In addition to this, many Christians attend services of worship on holy days such as Christmas, Ash Wednesday, Good Friday, Ascension Thursday, among others depending on the Christian denomination.

The Alexandrian rites are a collection of ritual families and uses of Christian liturgy employed by three Oriental Orthodox churches (the Coptic Orthodox Church, the Eritrean Orthodox Tewahedo Church, and the Ethiopian Orthodox Tewahedo Church), and by three Eastern Catholic Churches (the Coptic Catholic Church, the Eritrean Catholic Church, and the Ethiopian Catholic Church).

The Alexandrian rite's Divine Liturgy contains elements from the liturgies of Saints Mark the Evangelist (who is traditionally regarded as the first bishop of Alexandria), Basil the Great, Cyril of Alexandria, and Gregory of Nazianzus. The Alexandrian rites are sub-grouped into two rites: the Coptic Rite and the Ge'ez Rite.

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.
