Orthodox Church
From Srafopedia
The Eastern Orthodox Church is the second largest single Christian communion in the world. It is considered by its adherents to be the least changed from its ancient roots which stretch back to the beginnings of Christianity itself. It is composed of numerous theologically unified autocephalous ecclesial bodies each shepherded by a synod of independent bishops whose duty is to preserve the traditions of the Church, and who can trace their lineage back to one of the twelve Apostles through the process of apostolic succession.
Members of the Eastern Orthodox Church do not usually refer to themselves as "Eastern" Orthodox but rather with a prefix denoting their nation of origin. Thus, within this article, the terms "Greek", "Russian", or any other "National" Orthodox; as well as The Church, The Orthodox Church, The Byzantine Church, etc., all refer to a single unified entity, what is today commonly called the Eastern Orthodox Church.
In the 11th century the "Great Schism" took place between Rome and Constantinople, which led to separation of the Roman Catholic Church, and the Eastern Orthodox Church. There were doctrinal issues like the filioque clause and the authority of the Pope involved in the split, but these were exacerbated by cultural and linguistic differences between Latins and Greeks. Prior to that, the Eastern and Western halves of the Church had frequently been in conflict, particularly during periods of iconoclasm and the Photian schism.
The final breach is often considered to have arisen after the capture and sacking of Constantinople by the Fourth Crusade in 1204 . The sacking of the Church of Holy Wisdom and establishment of the Latin Empire as a seeming attempt to supplant the Orthodox Byzantine Empire in 1204 is viewed with some rancour to the present day. In 2004, Pope John Paul II extended a formal apology for the sacking of Constantinople in 1204; the apology was formally accepted by Patriarch Bartholomew of Constantinople.
