Church History

The Councils

The seven ecumenical councils, Western councils, conciliar authority and comparative reception

An ecumenical council is an assembly of bishops representing the whole Church, convened to settle a doctrinal or disciplinary question. How many councils are genuinely ecumenical, and on what grounds, is a question that divides the Christian traditions.

The seven ecumenical councils (325–787)

CouncilDateEmperorQuestionDecision
Nicaea I325ConstantineArianism — is the Son a creature?The Son is ὁμοούσιος, consubstantial with the Father. The Nicene Creed. The date of Easter fixed.
Constantinople I381Theodosius IThe divinity of the Spirit; ApollinarianismThe Spirit is “Lord and giver of life”, worshipped with the Father and the Son. The Niceno-Constantinopolitan Creed. Christ has a complete human soul.
Ephesus431Theodosius IINestorianism — is Mary Theotokos?Mary is Θεοτόκος, God-bearer, a christological affirmation of one person in Christ. Nestorius deposed.
Chalcedon451MarcianThe monophysitism of EutychesOne person in two natures, without confusion, change, division or separation. The normative christological formula.
Constantinople II553JustinianThe “Three Chapters” — an attempt to conciliate the monophysitesPosthumous condemnation of Theodore of Mopsuestia, Theodoret and Ibas. Chalcedon reaffirmed in a Cyrilline key.
Constantinople III680-681Constantine IVMonothelitism — one will in Christ or two?Two wills and two natural operations; the human will freely submits to the divine. Pope Honorius posthumously condemned.
Nicaea II787Irene (regent)Iconoclasm — is the veneration of images legitimate?Veneration (προσκύνησις) of icons is legitimate and distinct from the worship (λατρεία) due to God alone. The honour paid to the image passes to its prototype (Basil).

Protestant reception of Nicaea II (787)

The Reformed reject Nicaea II as a seventh normative council: the distinction between προσκύνησις and λατρεία is judged artificial, and the second commandment (Ex 20:4-5) forbids any cultic image. Zwingli and Calvin practised a Reformed iconoclasm. Lutherans are more nuanced: Luther tolerated images as teaching aids (Wider die himmlischen Propheten, 1525) provided they were not objects of worship. Anglicans retained images without formal cult.

Western councils after the schism

After 1054 the Latin Church continued to hold councils it regards as ecumenical but which Orthodoxy does not recognise. These councils gave formal shape to specifically Western doctrines.

CouncilDatePrincipal contributionProtestant reception
Lateran IV1215Transubstantiation defined as dogma. Annual confession made obligatory.Rejected on the ground that its Aristotelian categories lack scriptural warrant
Constance1414-1418End of the Western Schism. The decree Haec Sancta: a council holds authority above the pope (conciliarism). Jan Hus burned in 1415.Luther invoked the conciliarism of Constance against Rome. The condemnation of Hus remains a Protestant wound.
Florence1438-1445Attempted union with Orthodoxy. Decrees on the Filioque and papal primacy, signed by the Greek bishops and rejected by the faithful.Not directly at issue for Protestants, though the Eastern rejection illustrates the weight accorded to receptio.
Trent1545-1563Dogmatic answer to the Reformation: justification (session VI), the sacraments, Scripture and Tradition, disciplinary reform of the clergy.Rejected in its entirety. The anathemas against sola fide remain formally in force notwithstanding the Joint Declaration of 1999.
Vatican I1869-1870Papal infallibility ex cathedra; universal jurisdictional primacy of the pope.Rejected. It remains a principal obstacle in dialogue with Protestants and Orthodox alike.
Vatican II1962-1965Aggiornamento: vernacular liturgy, ecumenism, religious liberty, relations with non-Christian religions.The conciliatory tone was widely welcomed, but the dogmatic divergences remain unaltered.

Conciliar authority: three conceptions

Protestant

Derived and fallible authority. Luther at Leipzig in 1519, facing Eck: councils can err and have erred. Conciliar decisions carry authority only so far as they conform to Scripture (norma normata). The first four councils are received not because they are councils, but because their teaching is scriptural.

Westminster XXXI §4: all synods and councils since apostolic times, whether general or particular, may err and many have erred; they are therefore not to be made the rule of faith or practice, but a help.

Orthodox

Authority through reception. A council is ecumenical only if it is received by the conscience of the whole Church, clergy and laity alike. Neither imperial convocation nor episcopal signatures suffice. Florence in 1439 was signed by almost all the Greek bishops and rejected by the faithful; it is therefore not ecumenical.

Infallibility belongs to the whole Church, not to any single organ. The laity are guardians of Tradition (Encyclical of the Eastern Patriarchs, 1848).

Catholic

Infallible authority under the pope. A council is ecumenical if convoked or ratified by the pope and if its decrees are approved by him. A council gathered with the pope exercises the extraordinary infallible magisterium (Lumen Gentium §25).

Vatican I settled the conciliarist quarrel in the pope’s favour: the pope may define infallibly without a council, but no council may define without the pope.

Comparative reception: how many councils?

TraditionNumber recognisedCriterion
Roman CatholicTwenty-one, from Nicaea I to Vatican IIPapal convocation or ratification
OrthodoxSeven (325–787)Reception by the whole Church. Some Orthodox theologians count the Palamite councils of 1341-1351 as an eighth and ninth.
AnglicanThe first four, sometimes sixConformity to Scripture. Article XXI: general councils may err.
LutheranThe first four, received as to their doctrineConformity to Scripture (preface to the Augsburg Confession; Formula of Concord)
ReformedThe first four, received as to their doctrineConformity to Scripture. Nicaea II explicitly rejected.
Oriental OrthodoxThree, to Ephesus (431)Rejection of Chalcedon — miaphysite: Copts, Syriacs, Armenians and Ethiopians
Assyrian Church of the EastTwo: Nicaea and Constantinople IRejection of Ephesus — the dyophysite tradition often called “Nestorian”

Quiz — The Councils

Why do the Reformed churches reject Nicaea II (787) as a normative council?

  • Because it was convoked by an empress rather than an emperor
  • Because the veneration/worship distinction is judged artificial and contrary to Ex 20:4-5
  • Because it defined the Filioque against the East
  • Because it was not received by the patriarchate of Constantinople
