Ecumenical council

An ecumenical council, also called general council, is a meeting of bishops and other church authorities to consider and rule on questions of Christian doctrine, administration, discipline, and other matters in which those entitled to vote are convoked from the whole world (oikoumene) and which secures the approbation of the whole Church.

The word "ecumenical" derives from the Late Latin oecumenicus "general, universal", from Greek oikoumenikos "from the whole world", from he oikoumene ge "the inhabited world" (as known to the ancient Greeks); the Greeks and their neighbors, considered as developed human society (as opposed to barbarian lands); in later use "the Roman world" and in the Christian sense in ecclesiastical Greek, from oikoumenos, present passive participle of oikein ("inhabit"), from oikos ("house, habitation"). The first seven ecumenical councils, recognised by both the eastern and western denominations comprising Chalcedonian Christianity, were convoked by Roman Emperors, who also enforced the decisions of those councils within the state church of the Roman Empire.

Starting with the third ecumenical council, noteworthy schisms led to non-participation by some members of what had previously been considered a single Christian Church. Thus, some parts of Christianity did not attend later councils, or attended but did not accept the results. Bishops belonging to what became known as the Eastern Orthodox Church accept seven ecumenical councils, as described below. Bishops belonging to what became known as the Church of the East participated in the first two councils. Bishops belonging to what became known as Oriental Orthodoxy participated in the first four councils, but rejected the decisions of the fourth and did not attend any subsequent ecumenical councils.

Acceptance of councils as ecumenical and authoritative varies between different Christian denominations. Disputes over Christological and other questions have led certain branches to reject some councils that others accept.

The Church of the East (accused by others of adhering to Nestorianism) accepts as ecumenical the first two councils. Oriental Orthodox Churches accept the first three, while some accept also the previous Second Council of Ephesus.

Both the Catholic Church and Eastern Orthodox Church recognize as ecumenical the first seven councils, held from the 4th to the 9th centuries. While some Eastern Orthodox accept one later council as ecumenical (which was later repudiated by the Catholic Church), the Catholic Church continues to hold general councils of the bishops in full communion with the Pope, reckoning them as ecumenical. In all, the Catholic Church recognizes twenty-one councils as ecumenical.

The first four ecumenical councils are recognized by some Lutheran Churches, Anglican Communion and Reformed Churches—though they are "considered subordinate to Scripture". The Lutheran World Federation recognizes the first seven Ecumenical Councils as "exercises of apostolic authority" and recognizes their decisions as authoritative; while member churches are not required to accept all theological statements produced by the Federation, but only to subscribe to the most basic Lutheran historical confessional documents, most do follow this recommendation.

The doctrine of the infallibility of ecumenical councils states that solemn definitions of ecumenical councils, which concern faith or morals, and to which the whole Church must adhere, are infallible. Such decrees are often labeled as 'Canons' and they often have an attached anathema, a penalty of excommunication, against those who refuse to believe the teaching. The doctrine does not claim that every aspect of every ecumenical council is dogmatic, but that every aspect of an ecumenical council is free of errors or impeccable.
