Controversy and heresy

Councils and major events

  • Constantinople, 843 (a local synod): In January 842, the image-breaking emperor Theophilos died. His widow Theodora ruled for their young son Michael III. With Patriarch Methodios, she ended the ban on icons (holy pictures). A synod renewed the decree of Nicaea II (787). A procession then carried icons back into the church. The East keeps the day as the Feast of Orthodoxy, on the first Sunday of Lent. The argument rests on the incarnation. The Son became truly human, so he can be painted. P: Synodikon of Orthodoxy, early form V1: Catholic Encyclopedia, Iconoclasm V2: Orthodox Church in America, The End of Iconoclasm. The Catholic Encyclopedia dates the restoration to 842. Most modern accounts use 843. The Synodikon text grew over the centuries, so read only its early core.
    • Lutheran classification: Mixed. The synod adds no new doctrine, and the Confessions share its base that the Son truly became flesh. They do not require honoring icons or calling on saints. Augsburg Confession III, Apology XXI
  • Quierzy, 853 (a regional synod): Bishops loyal to King Charles the Bald adopted four chapters by Hincmar. They say God chose some for eternal life. They say God foresaw which people were lost, and he set eternal punishment for them. They say God wills all to be saved and that Christ died for all. P: Four chapters of Quierzy, quoted in Schaff §122, notes 687–689 V1: Catholic Encyclopedia, Councils of Quierzy V2: Catholic Encyclopedia, Hincmar. The tie to Christ is chapter 4. Christ died for all people, though unbelief keeps some from his gift.
    • Lutheran classification: Mixed. The Confessions accept Quierzy’s teaching that God wills all to be saved, that Christ died for all, and that God does not predestine anyone to damnation. They reject its view that the will, once freed by grace, cooperates with grace toward salvation. Formula of Concord XI, Formula of Concord II
  • Valence, 855 (a regional synod): Remigius of Lyon led this synod. It refused to approve Hincmar’s four chapters. Its canons teach a two-fold predestination, of the elect to life and of the wicked to death, with careful limits. The Synod of Langres repeated them in 859. P: Canons of Valence, Mansi XV, summarized in Schaff §122, note 685 V1: Catholic Encyclopedia, Hincmar V2: Schaff-Herzog Encyclopedia, Remigius of Lyons. The synod joins the same dispute about Christ’s saving work for all.
    • Lutheran classification: Mixed. The Confessions agree that sin binds the will and that election is pure grace. They reject any predestination of the wicked to death. Formula of Concord II, Formula of Concord XI
  • Constantinople, 869–870 (Rome’s eighth ecumenical council): The council met from 5 October 869 to 28 February 870. Legates of Pope Hadrian II presided. It condemned Photius, upheld Ignatius, and issued 27 canons. Canon 3 says Christians must honor the icon of Christ as they honor the Gospel book. The council also condemns those who taught that Christ’s body was only an appearance. Canon 21 forbids rulers to remove patriarchs and names the pope first in honor. Rome counts this council as ecumenical, and the profession of faith prescribed at Constance lists it as the eighth. The Eastern churches do not count it. P: Acts of Constantinople 869–870, canons 3 and 21 P: Constance, session 39, papal profession V1: Catholic Encyclopedia, Constantinople IV V2: Sagovsky, section 3.3. The council’s own claims do not prove that the whole church received it.
    • Lutheran classification: Mixed. The Confessions accept its confession of one Christ, both visible and invisible. That matches Augsburg III. They reject canon 21’s ranking of the pope. They also reject canon 3’s order to honor saints’ icons, since they do not require icons or the calling on saints. Smalcald Articles II IV, Augsburg Confession III
  • Constantinople, 879–880 (the Photian council): This council restored Photius. It confirmed Nicaea II (787). Its rule of faith (the Horos) keeps the Creed as received. It forbids writing another creed, adding to the Creed, or removing anything from it. Read these words before you decide what they mean for the Filioque. Legates of Pope John VIII attended. P: Horos, acts 6–7, in Dragas, part c V1: OCA, Photius V2: Słomski, The horos and the Creed. The Horos does not name the Filioque. How far its ban reaches is an open question. Dragas is an Orthodox priest and reads it as a ban on the Filioque. The Catholic Encyclopedia says only the Greeks count these Photian synods as the eighth council.
    • Lutheran classification: Mixed. The Confessions receive the Creed that this council guards, and its Christ-centered faith. They do not read its ban on additions as a ban on the Filioque. The Book of Concord prints the Creed with “and the Son.” Nicene Creed in the Book of Concord, Augsburg Confession I
  • Reception of the two councils: The 879 council cancelled the 869–870 council. Rome’s list kept 869–870. Many Greek Orthodox writers instead call 879–880 the eighth council. Compare the two lists and do not assume a shared numbering. P: Horos and Basil’s subscription, in Dragas, part c V1: Catholic Encyclopedia, Photian synods V2: OCA, Photius. A modern Catholic or Orthodox verdict is not the council’s own voice.
