Eastern Orthodox ChurchThe Eastern Orthodox Church, also called the Orthodox Church and officially the Orthodox Catholic Church, is the second-largest Christian church, with approximately 220 million baptized members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the head of the Catholic Church—the pope—but the Ecumenical Patriarch of Constantinople is recognized by them as primus inter pares ("first among equals").
Four Marks of the ChurchThe Four Marks of the Church, also known as the Attributes of the Church, describes four distinctive adjectives of traditional Christian ecclesiology as expressed in the Niceno-Constantinopolitan Creed completed at the First Council of Constantinople in AD 381: "[We believe] in one, holy, catholic, and apostolic Church.
Latin ChurchThe Latin Church (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 Christians in communion with the Pope in Rome. The Latin Church is one of 24 churches sui iuris in communion with the pope; the other 23 are referred to as the Eastern Catholic Churches, and 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.
Christian denominationA Christian denomination is a distinct religious body within Christianity that comprises all church congregations of the same kind, identifiable by traits such as a name, particular history, organization, leadership, theological doctrine, worship style and, sometimes, a founder. It is a secular and neutral term, generally used to denote any established Christian church. Unlike a cult or sect, a denomination is usually seen as part of the Christian religious mainstream.
Catholic theologyCatholic 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. Major teachings of the Catholic Church discussed in the early councils of the church are summarized in various creeds, especially the Nicene (Nicene-Constantinopolitan) Creed and the Apostles' Creed.
Christian ChurchIn ecclesiology, the Christian Church is what different Christian denominations conceive of as being the true body of Christians or the original institution established by Jesus. "Christian Church" has also been used in academia as a synonym for Christianity, despite the fact that it is composed of multiple churches or denominations, many of which hold a doctrinal claim of being the "one true church", to the exclusion of the others.
Western ChristianityWestern Christianity is one of two subdivisions of Christianity (Eastern Christianity being the other). Western Christianity is composed of the Latin Church and Western Protestantism, together with their offshoots such as the Old Catholic Church, Independent Catholicism and Restorationism. The large majority of the world's 2.3 billion Christians are Western Christians (about 2 billion – 1.2 billion Latin Catholic and 800 million Protestant). The original and still major component, the Latin Church, developed under the bishop of Rome.
Biblical canonA biblical canon is a set of texts (also called "books") which a particular Jewish or Christian religious community regards as part of the Bible. The English word canon comes from the Greek κανών kanōn, meaning "rule" or "measuring stick". The use of the word "canon" to refer to a set of religious scriptures was first used by David Ruhnken, in the 18th century. Various biblical canons have developed through debate and agreement on the part of the religious authorities of their respective faiths and denominations.
Full communionFull communion is a communion or relationship of full agreement among different Christian denominations or Christian individuals that share certain essential principles of Christian theology. Views vary among denominations on exactly what constitutes full communion, but typically when two or more denominations are in full communion it enables services and celebrations, such as the Eucharist, to be shared among congregants or clergy of any of them with the full approval of each.
SacrednessSacred describes something that is dedicated or set apart for the service or worship of a deity; is considered worthy of spiritual respect or devotion; or inspires awe or reverence among believers. The property is often ascribed to objects (a "sacred artifact" that is venerated and blessed), or places ("sacred ground"). French sociologist Émile Durkheim considered the dichotomy between the sacred and the profane to be the central characteristic of religion: "religion is a unified system of beliefs and practices relative to sacred things, that is to say, things set apart and forbidden.
