Council of Ephesus

“And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.”

— John 1:14

The Council of Ephesus was the third of the ecumenical councils, convened in AD 431 at Ephesus by the emperor Theodosius II.¹ It condemned the teaching of Nestorius, patriarch of Constantinople, that the eternal Son and the man born of Mary were joined only in a moral “conjunction” rather than one person,² and it affirmed Mary as Theotokos, “God-bearer,” as a vindication of Christ’s divinity rather than an honor to her.³ Nestorius was deposed and banished; his followers organized a separate communion in the East that continues to this day.⁴ The same council also renewed the church’s condemnation of Pelagianism.⁵

Confessional Definition

The 1689 Second London Baptist Confession does not name the Council of Ephesus or any other council by name. The Second Helvetic Confession does, receiving it as the second of the “first four most excellent synods convened at Nicaea, Constantinople, Ephesus and Chalcedon,” alongside the Athanasian Creed, on the ground that “nothing is contained in the aforesaid symbols which is not agreeable to the Word of God.”⁶ Benedict Pictet states the wider Reformed principle: a council’s decisions carry “an authority far beneath that of scripture; nor can their decisions bind the conscience any further, than they appear to be consistent with the word of God.”¹ Ephesus’s condemnation of Nestorius is received, on this view, because its content agrees with Scripture’s own witness to Christ, not because an imperially convened synod carries binding authority in its own right.

Historical Development

The dispute originated in a disagreement over how to describe Mary. Nestorius, trained in the Antiochene school, opposed calling her Theotokos (“God-bearer”) and preferred Christotokos (“Christ-bearer”), a term he thought “embraced both aspects of the nature of Christ” without implying that the eternal, unbeginning God had been born of a woman.⁷ In his own words: “The creature did not give birth to the creator; she gave birth to a man, the instrument of deity… from the virgin the Holy Spirit framed a temple for God the Word in which he should dwell.”⁸ Cyril, patriarch of Alexandria, took the opposite view: “if our Lord Jesus Christ is God, then surely the holy Virgin who gave him birth must be God’s mother.”⁹ Bavinck states the doctrinal substance of Nestorius’s position: he held the eternal Son “distinct from and other than” the son of David born of Mary, their union “not a natural but a moral union; not a union (henosis) but a conjunction (synapheia) of two natures,” with God’s indwelling of Christ differing from his indwelling of ordinary believers only in degree, not in kind.²

Cyril’s own letter, read and received at the council, argued that Nestorius’s language, whatever his intent, could not avoid dividing Christ into two subjects: “We must not, therefore, divide the one Lord Jesus Christ into two Sons.”¹⁰ Cyril secured Nestorius’s condemnation, though Hodge’s own account does not present this as an orderly or undisputed judgment: he “secured his condemnation by violent means in the Synod of Ephesus,” and the decision “was resisted by the Greek and Syrian bishops, so that the controversy, for a time at least, was a conflict between these two sections of the Church.”⁴ Nestorius was deposed and ultimately banished, dying in AD 440; his followers “removed eastward to Persia, and organized themselves into a separate communion, which continues until this day.”⁴

Hodge is explicit that the council’s ruling on Mary’s title was “rendered rather as a vindication of the divinity of Christ, than as an exaltation of the glory of the Blessed Virgin”: the underlying question was whether the person born of Mary was truly God, not how Mary herself ought to be honored.³ The same synod also renewed the wider church’s condemnation of Pelagius and his teaching on human nature and grace, following the earlier councils of Carthage (418) and anticipating the Synod of Orange (529).⁵

This 431 council should not be confused with a second, later synod held at the same city in AD 449, at which the Alexandrian patriarch Dioscorus presided in his own right, Flavian of Constantinople was condemned, and the Eutychian position later rejected at Chalcedon was approved; Calvin distinguishes the two, treating the 449 assembly, unlike the 431 council, as no true council at all.¹¹

Opposing Views

Roman Catholic theology traces a direct line from Ephesus’s ruling to later Marian devotion. Hodge, no friend to that later development, still locates its origin at this council: in the years immediately after, the bishops “were escorted from their place of meeting by a multitude bearing torches, preceded by women bearing censers filled with burning incense,” and the “authoritative decision” at Ephesus “marks a distinct epoch in the progress of the deification of the Virgin,” which later produced feasts, shrines, and even a parody “Psalter of the Virgin” addressing to Mary language Scripture addresses to God.³

Reformed theology accepts the same decision on different grounds. Hodge argues the title itself is “proper and according to the analogy of Scripture”: the Virgin was the mother of Christ, and Christ is God manifest in the flesh, so calling her the mother of God no more denies the distinction of Christ’s two natures than calling him the Son of Man denies his deity.³ What the Reformed tradition rejects is not the council’s own ruling but everything built onto it afterward. On the council’s political shape, Calvin reads the record of Roman participation as evidence against later claims of papal primacy: Celestinus, bishop of Rome, “used a cunning device to secure the dignity of his See,” making Cyril his substitute to preside rather than presiding himself, so that his legates “sit in an inferior place, are asked their opinion along with others.”¹¹ On Reformed principle, a council is ecumenical because its content agrees with Scripture, not because a pope’s endorsement makes it so, in contrast to Rome’s later claim, in Bavinck’s summary, that “a council is ecumenical only when its decrees have been endorsed by the pope and have thereby acquired an infallible, universally binding character.”¹²

Objections and Responses

Cyril “secured his condemnation by violent means,” and the Greek and Syrian bishops resisted the decision at the time. Was Ephesus a fair judgment or a power struggle dressed as orthodoxy? Hodge does not conceal the irregularity of the proceedings, but he does not treat it as grounds for doubting the verdict either: the Greek and Syrian bishops’ resistance shows the decision was contested, not that it was wrong, and their later reconciliation to the wider church left Nestorius’s own teaching, not the council’s procedure, as the unresolved question.⁴ On Reformed principle stated above, a council’s authority rests on whether its content agrees with Scripture, not on the orderliness of its proceedings, so a genuine procedural irregularity does not by itself unsettle a doctrinally correct verdict.¹

Nestorius insisted he was not teaching two persons in Christ, only guarding the distinction between the divine and human natures. Was the council condemning what he actually taught, or a caricature of it? Hodge does not overclaim the charge: “Nestorius was accused of teaching that the Logos only inhabited the man Jesus, whence it was inferred that he held that the person born of the Virgin was simply human.”³ The accusation was an inference from his language, not a claim that Nestorius stated the “two persons” position outright. Cyril’s own argument at the council was that the inference was unavoidable regardless of intent: a “conjunction” of two natures that stops short of a real personal union still, on examination, requires treating the divine and human as two subjects merely joined together, which is what “dividing the one Lord Jesus Christ into two Sons” means, whatever term is used to describe the joining.¹⁰
