Roman Rite in the context of "Sarum Rite"

The Catholic Church (Latin: Ecclesia Catholica), also known as the Roman Catholic Church, is the largest Christian church, with 1.27 to 1.41 billion baptized Catholics worldwide as of 2025. It is among the world's oldest and largest international institutions and has played a prominent role in the history and development of Western civilization. The Church consists of 24 sui iuris (autonomous) churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies around the world, each overseen by one or more bishops. The pope, who is the bishop of Rome, is the chief pastor of the church.

The core beliefs of Catholicism are found in the Nicene Creed. The Catholic Church teaches that it is the one, holy, catholic and apostolic church founded by Jesus Christ in his Great Commission, that its bishops are the successors of Christ's apostles, and that the pope is the successor of Saint Peter, upon whom primacy was conferred by Jesus Christ. It maintains that it practises the original Christian faith taught by the apostles, preserving the faith infallibly through scripture and sacred tradition as authentically interpreted through the magisterium or teaching office of the church. The Roman Rite and others of the Latin Church, the Eastern Catholic liturgies, and communities and societies such as mendicant orders, enclosed monastic orders, third orders and voluntary charitable lay associations reflect a variety of theological and spiritual emphases in the church.

Religion in Hungary is varied, with Christianity being the largest religion. In the national census of 2022, 42.5% of the population identified themselves as Christians, of whom 29.2% were adherents of Catholicism (27.5% following the Roman Rite, and 1.7% the Greek Rite), 9.8% of Calvinism, 1.8% of Lutheranism, 0.2% of Eastern Orthodox Christianity, and 1.5% of other Christian denominations. 1.3% of the population identified themselves as adherents of other religions; minorities practising Judaism, Islam, Buddhism, Hinduism, the Baháʼí Faith, Taoism, Hungarian Neopaganism and other Neopaganisms, and New Age, are present in the country. At the same time, 40.1% of the population did not answer, not identifying their beliefs or non-beliefs, while 16.1% identified themselves as not religious.

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.

Pentecost (also called Whit Sunday, Whitsunday or Whitsun) is a Christian holiday that takes place on the 49th day (50th day when inclusive counting is used) after Easter. It commemorates the descent of the Holy Spirit upon the Apostles of Jesus, Mary, and other followers of the Christ, while they were in Jerusalem celebrating the Feast of Weeks, as described in the Acts of the Apostles (Acts 2:1–31). Pentecost marks the "Birthday of the Church".

Pentecost is one of the Great feasts in the Eastern Orthodox Church, a Solemnity in the Roman Rite of the Catholic Church, a Festival in the Lutheran Churches, and a Principal Feast in the Anglican Communion. Many Christian denominations provide a special liturgy for this holy celebration. Since its date depends on the date of Easter, Pentecost is a "moveable feast". The Monday after Pentecost is a legal holiday in many European, African and Caribbean countries.

The Anaphora (/əˈnæfərə/), Eucharistic Prayer, or Great Thanksgiving, is a portion of the Christian liturgy of the Eucharist in which, through a prayer of thanksgiving, the elements of bread and wine are consecrated. The prevalent historical Roman Rite form is called the "Canon of the Mass".

"Anaphora" is a Greek word (ἀναφορά) meaning a "carrying up", thus an "offering" (hence its use in reference to the offering of sacrifice to God). (This sense is distinct from the usage of "anaphora" in rhetoric and linguistics to mean a "carrying back".) In the sacrificial language of the Greek version of the Hebrew Bible known as the Septuagint, προσφέρειν (prospherein) is used of the offerer's bringing the victim to the altar, and ἀναφέρειν (anapherein) is used of the priest's offering up the selected portion upon the altar (see, for instance, Leviticus 2:14, 2:16, 3:1, 3:5).
