Essentially the Orthodox Church shares much with the other Christian Churches in the belief that God revealed himself in Jesus Christ, and a belief in the incarnation of Christ, his crucifixion and resurrection. The Orthodox Church differs substantially in the way of life and worship.

Orthodox Christians believe in a single God who is both three and one (triune); the Father, Son, and Holy Spirit, “one in essence and undivided”. The Holy Trinity is three “unconfused” and distinct divine persons (hypostases), who share one divine essence (ousia); uncreated, immaterial and eternal.

Orthodox Churches, unlike the Catholic Church, have no Bishopric head, such as a Pope, and hold the belief that Christ is the head of the Church. However, they are each governed by a committee of Bishops, called the Holy Synod, with one central Bishop holding the honorary title of “first among equals.”

Orthodoxy (from Greek ὀρθοδοξία, orthodoxia – “right opinion”) is adherence to correct or accepted 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”.

Christian Universalists agree with both Calvinists and Arminians that everyone is born in sin and in need of salvation. They also believe that one is saved by Jesus Christ. However, they emphasize that judgment in hell upon sinners is of limited duration, and that God uses judgment to bring sinners to repentance.

Orthodox practices or beliefs are generally accepted as true or correct. … Orthodox is also the name of the branch of Judaism that strictly follows traditional beliefs and customs, derived from orthodox in the earlier meaning of “strictly observant.”

At the time of the Schism of 1054 between Rome and Constantinople, the membership of the Eastern Orthodox Church was spread throughout the Middle East, the Balkans, and Russia, with its centre in Constantinople, which was also called “New Rome.”
