Eastern Christianity comprises church families that developed outside the Occident, with major bodies including the Eastern Orthodox Church, the Oriental Orthodox churches, the Eastern Catholic churches, and the denominations descended from the Church of the East.
The Eastern Catholic Churches or Oriental Catholic Churches, also called the Eastern-rite Catholic Churches, and in some historical cases Uniate Churches, are twenty-three Eastern Christian autonomous particular churches in full communion with the pope in Rome, as part of the worldwide Catholic Church. They are united with one another and with the Latin or Roman Church. In particular, they recognize the central role of the Bishop of Rome within the College of Bishops and his infallibility when speaking ex cathedra. The majority of the Eastern Catholic Churches are groups from the Eastern Orthodox Church, the Oriental Orthodox churches, and the historic Church of the East that have returned to communion with the Bishop of Rome, either due to theological concerns or due to understanding the role of the Bishop of Rome as head of church. As such the five liturgical traditions of the twenty-three Eastern Catholic Churches, including the Alexandrian Rite, the Armenian Rite, the Byzantine Rite, the East Syriac Rite, and the West Syriac Rite, are shared with other Eastern Christian churches. Consequently, the Catholic Church consists of six liturgical rites; including the aforementioned five liturgical traditions of the Eastern Catholic Churches along with the Latin liturgical rites of the Latin Church.
Traditionalist Catholicism is a set of religious beliefs and practices comprising customs, traditions, liturgical forms, public and private, individual and collective devotions, and presentations of Catholic Church teachings that were in vogue in the decades that immediately preceded the Second Vatican Council (1962–65). It is associated in particular with attachment to the 1570–1970 form of the Roman Rite Mass, which traditionalist Catholics call the Traditional Latin Mass or TLM or the Extraordinary Form of the Mass.
The Ruthenian Greek Catholic Church, also known in the United States as the Byzantine Catholic Church, is an Eastern Catholic church that uses the Byzantine Rite for its liturgies, laws, and cultural identity. It is one of the 23 Eastern Catholic churches that are in full communion with the Holy See. There are two main communities within the church: American and European. In the United States, the Byzantine Catholic Metropolitan Church of Pittsburgh is self-governing. In Europe, Ruthenian Catholics are immediately subject to the Holy See. The European branch has an eparchy in Ukraine and another in the Czech Republic.
The Russian Greek Catholic Church, or Russian Catholic Church, is a sui iuris Byzantine Rite Eastern Catholic Church. Historically, it represents the first reunion of members of the Russian Orthodox Church with the Roman Catholic Church. It is now in full communion with and subject to the authority of the Pope as defined by Eastern canon law.
Catholic Mariology refers to Mariology—the systematic study of the person of Mary, mother of Jesus, and of her place in the Economy of Salvation—within Catholic theology. Mary is seen as having a singular dignity above the saints. The Catholic Church teaches that she was conceived without original sin, therefore receiving a higher level of veneration than all other saints. Catholic Mariology thus studies not only her life but also the veneration of her in daily life, prayer, hymns, art, music, and architecture in modern and ancient Christianity throughout the ages.
The Roman Rite is the main liturgical rite of the Latin Church, the main particular church sui iuris of the Catholic Church. It is the most widespread liturgical rite in Christianity as a whole. The Roman Rite gradually became the predominant rite used by the Western Church, developed out of many local variants from Early Christianity on, not amounting to distinctive rites, that existed in the medieval manuscripts, but have been progressively reduced since the invention of printing, most notably since the reform of liturgical law in the 16th century at the behest of the Council of Trent (1545–63) and more recently following the Second Vatican Council (1962–65).
Latin liturgical rites, or Western liturgical rites, are Catholic liturgical rites 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. Its language is now known as Ecclesiastical Latin. The most used rite is the Roman Rite.
Catholicity is a concept pertaining to beliefs and practices widely accepted across numerous Christian denominations, most notably those that describe themselves as Catholic in accordance with the Four Marks of the Church, as expressed in the Nicene Creed of the First Council of Constantinople in 381: "[I believe] in one, holy, catholic, and apostolic Church."
The sacrament of holy orders in the Catholic Church includes three orders: bishop, priest, and deacon. In the phrase "holy orders", the word "holy" simply means "set apart for some purpose." The word "order" designates an established civil body or corporation with a hierarchy, and ordination means legal incorporation into an order. In context, therefore, a group with a hierarchical structure that is set apart for ministry in the Church.
The priesthood is one of the three holy orders of the Catholic Church, comprising the ordained priests or presbyters. The other two orders are the bishops and the deacons. Only men are allowed to receive holy orders, and the church does not allow any transgender people to do so. Church doctrine also sometimes refers to all baptised Catholics as the "common priesthood".
Catholic theology is the understanding of Catholic doctrine or teachings, and results from the studies of theologians. It is based on canonical scripture, and sacred tradition, as interpreted authoritatively by the magisterium of the Catholic Church. This article serves as an introduction to various topics in Catholic theology, with links to where fuller coverage is found.
Mariology is the theological study of Mary, the mother of Jesus. Mariology methodically relates teachings about her to other parts of the faith, such as teachings about Jesus, redemption and grace. Christian Mariology aims to connect scripture, tradition and the teachings of the Catholic Church on Mary. In the context of social history, Mariology may be broadly defined as the study of devotion to and thinking about Mary throughout the history of Christianity.
The history of Catholic Mariology traces theological developments and views regarding Mary from the early Church to the 21st century. Mariology is a mainly Catholic ecclesiological study within theology, which centers on the relation of Mary and the Church. Catholic Mariology is the encyclopedic area of theology concerned with Mary, the Mother of God. Theologically, it not only deals with her life, but her veneration in daily life, prayer, art, music, architecture, in modern and ancient Christianity throughout the ages.
Ecumenical meetings and documents on Mary is a review of the status of Mariology in the Orthodox, Protestant, Anglican, and Roman Catholic Churches, as a result of ecumenical commissions and working groups.
Anglican–Roman Catholic dialogue is the historical communication between the Anglican Communion and the Roman Catholic Church, through their ecumenical relations. These were notably shaped subsequent to the Second Vatican Council (1962–1965).
This is a glossary of terms used within the Catholic Church.
A particular church is an ecclesiastical community of faithful headed by a bishop, as defined by Catholic canon law and ecclesiology. A liturgical rite depends on the particular church the bishop belongs to. Thus "particular church" refers to an institution, and "liturgical rite" to its practices.
The Latin Church, also known as the Western Church or the Roman Catholic Church, is the largest particular church sui iuris of the Catholic Church, employing the Latin liturgical rites. It is one of 24 such churches, the 23 others forming the Eastern Catholic Churches. It is headed by the Bishop of Rome, the pope – traditionally also called the Patriarch of the West – with his cathedra in this role at the Archbasilica of Saint John Lateran in Rome, Italy. The Latin Church traces its history to the earliest days of Christianity through its direct leadership under the Holy See, founded by Peter and Paul, according to Catholic tradition.
