The Orthodox Church considers Jesus Christ to be the head of the Church and the Church to be His body. Thus, despite widely held popular belief outside the Eastern Orthodox cultures, there is not one bishop at the head of the Eastern Orthodox Church; references to the Patriarch of Constantinople as a leader equivalent or comparable to a pope in the Roman Catholic Church are mistaken. It is believed that authority and the grace of God is directly passed down to Eastern Orthodox bishops and clergy through the laying on of hands—a practice started by the apostles, and that this unbroken historical and physical link is an essential element of the true church (Acts 8:17, 1 Tim 4:14, Heb 6:2). However, the church asserts that Apostolic Succession also requires Apostolic Faith, and bishops without Apostolic Faith, who are in heresy, forfeit their claim to Apostolic Succession. Each bishop has a territory (see) over which he governs. His main duty is to make sure the traditions and practices of the Church are preserved. Bishops are equal in authority and cannot interfere in the jurisdiction of another bishop. Administratively, these bishops and their territories are organized into various autocephalous groups or synods of bishops who gather together at least twice a year to discuss the state of affairs within their respective sees. While bishops and their autocephalous synods have the ability to administer guidance in individual cases, their actions do not usually set precedents that affect the entire Church. Bishops are almost always chosen from the monastic ranks and must remain unmarried.
There have been a number of times when alternative theological ideas arose to challenge the Orthodox faith. At such times the Church deemed it necessary to convene a general or "Great" council of all available bishops throughout the world. The Church considers the first seven ecumenical councils (held between the 4th and the 8th century) to be the most important; however, there have been more, specifically the Synods of Constantinople, 879–880, 1341, 1347, 1351, 1583, 1819, and 1872, the Synod of Iaşi (Jassy), 1642, and the Pan-Orthodox Synod of Jerusalem, 1672, all of which helped to define the Eastern Orthodox position. The ecumenical councils followed a democratic form; with each bishop having one vote. Though present and allowed to speak before the council, members of the Imperial Roman/Byzantine court, abbots, priests, monks and laymen were not allowed to vote. The primary goal of these Great Synods was to verify and confirm the fundamental beliefs of the Church as truth, and to remove as heresy any false teachings that would threaten the Church. The Pope of Rome, at that time, held the position of “First Among Equals”. And while he was not present at any of the councils he continued to hold this title until the East-West Schism of 1054 AD. One of the decisions made by the First Council of Constantinople (the second ecumenical council, meeting in 381) and supported by later such councils was that the Patriarch of Constantinople should be given equal honor with the Pope of Rome since Constantinople was considered to be the "New Rome". The Pope's name would be first in the Diptychs because Rome was the elder capital (see Canon 28 of the Fourth Ecumenical Council). The Patriarch, like the Pope before him enjoys the title of “First among Equals”. This is not, however, meant to imply that he is the leader of the Orthodox Church.
