Eastern Orthodox Church

The Eastern Orthodox Church, officially the Orthodox Catholic Church, also referred to as the Orthodox Church, Eastern Orthodoxy, and Orthodoxy, is the second largest Christian Church in the world, with an estimated 225–300 million adherents.

The Eastern Orthodox Church is one of the oldest religious institutions in the world, teaching that it is the One, Holy, Catholic and Apostolic Church established by Jesus Christ in his Great Commission to the apostles, and practicing what it understands to be the original faith passed down from the Apostles.

United in communion with the Latin Church before the East–West Schism in 1054, and with the Oriental churches for the first quarter of its history, Eastern Orthodoxy spread throughout the Roman and later Byzantine Empires and beyond, playing a prominent role in European, Near Eastern, Slavic, and some African cultures. Its most prominent episcopal see is Constantinople.

Eastern Orthodoxy has no Papacy or similar authority, but instead teaches that all bishops are equal by virtue of their ordination, and each autocephalous church is typically governed by a Holy Synod. This is one of the main reasons for the division between the Roman Catholic Church and the Eastern Orthodox Church. The commonly-used but unofficial designation "Eastern" derives from the geographical location of the main centers of Orthodoxy in relation to the "Western" churches (now known as the Roman Catholic Church), and from Constantinople being the capital of the Eastern Roman Empire.

Orthodoxy

Orthodoxy (from Greek ὀρθοδοξία, orthodoxia – "correct belief", "right opinion") is adherence to correct or accepted norms, more specifically to creeds, especially in religion. In the Christian sense the term means "conforming to the Christian faith as represented in the creeds of the early Church". The first seven Ecumenical Councils were held over the period between the years 325 and 787 with the aim of formalizing accepted doctrines.

Related concepts

Orthodoxy is opposed to heterodoxy ("other teaching") or heresy. People who deviate from orthodoxy by professing a doctrine considered to be false are called heretics, while those who, perhaps without professing heretical beliefs, break from the perceived main body of believers are called schismatics. The term employed sometimes depends on the aspect most in view: if one is addressing corporate unity, the emphasis may be on schism; if one is addressing doctrinal coherence, the emphasis may be on heresy. A deviation lighter than heresy is commonly called error, in the sense of not being grave enough to cause total estrangement, while yet seriously affecting communion. Sometimes error is also used to cover both full heresies and minor errors.

Catholic Church

The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with more than 1.25 billion members worldwide. One of the oldest religious institutions in the world, it has played a prominent role in the history of Western civilisation.Headed by the Bishop of Rome, known as the Pope, its doctrines are summarised in the Nicene Creed. The Catholic Church is also notable within the Western Christian tradition for its celebration of the seven sacraments.

The Catholic Church teaches that it is the one true church founded by Jesus Christ, that its bishops are the successors of Christ's apostles, and that the Pope is the successor to Saint Peter. The Church maintains that the doctrine on faith and morals that it declares as definitive is infallible. The Latin Church, the autonomous Eastern Catholic Churches and religious institutes such as the Jesuits, mendicant orders and enclosed monastic orders, reflect a variety of theological emphases in the Church.
