Third Council of Constantinople

The Sixth Ecumenical Council, convened by Constantine IV in a domed hall of the imperial palace, condemned monoenergism and monothelitism and defined that Christ has two natural wills and two energies, divine and human, the human will obeying the divine. It anathematized the authors and supporters of the doctrine, among them Patriarch Sergius and Pope Honorius I, and ended the breach between Constantinople and Rome.

The dispute went back to Heraclius. To win back the Miaphysites of Syria, Egypt and Armenia, who rejected the Council of Chalcedon, Patriarch Sergius of Constantinople proposed that Christ, though in two natures, had a single energy, and then — in Heraclius’s Ecthesis of 638 — a single will. Sophronius of Jerusalem and the monk Maximus the Confessor opposed the formula, the popes rejected the Ecthesis, and when Constans II forbade all discussion of the question in an edict known as the Type, a synod at the Lateran under Pope Martin I condemned both documents in 649. Martin was arrested, condemned in Constantinople and exiled to Cherson, where he died; Maximus was mutilated.

After repelling the Arab attack on his capital, Constantine IV sought reconciliation with Rome. Pope Agatho had the Western position prepared at regional synods — one of them at Hatfield in England under Archbishop Theodore — and at a Roman synod at Easter 680, and sent legates with his letter to the emperor. The council opened on 7 November 680 in the Trullus, a domed hall of the imperial palace, with only a few dozen bishops (37 or 43, according to different counts); Constantine IV presided over its first eleven sessions and returned for the last, on 16 September 681, by which time more than 150 bishops took part (151 or 174, according to different counts). The fathers acclaimed Agatho’s letter, proclaiming that Peter had spoken through Agatho, and deposed Patriarch Macarius of Antioch, who defended monothelitism.

The definition affirmed two natural wills and two energies in Christ, the human will being “in subjection to his divine and all-powerful will”, and anathematized the patriarchs Sergius, Pyrrhus, Paul and Peter of Constantinople, Cyrus of Alexandria and Pope Honorius I, who had endorsed Sergius’s view in 635; his condemnation later figured in debates on papal infallibility. Pope Leo II confirmed the decrees. Questions of church discipline were taken up by the Council in Trullo in 692, whose canons the Eastern Church counts as those of the Sixth Council.
