Peter of Constantinople

Peter of Constantinople (Greek: Πέτρος; died 12 October 666) was the Ecumenical Patriarch of Constantinople from 9 June 654 to 666. He was condemned as a heretic in the Third Council of Constantinople. He was succeeded as ecumenical patriarch by Thomas II of Constantinople.

Peter succeeded patriarch Pyrrhus who also was a Monothelite. In correspondence with Pope Vitalian of Rome following Vitalian's ascension to the see of Rome, Peter was noncommittal concerning Monothelitism, leading to a restoration of ecclesiastical intercourse between Rome and Constantinople. This resulted the addition of Vitalian's name on the diptychs of the church in Constantinople – the only name of a pope so entered between the reign of Pope Honorius I, who died in 638, and 677 when Patriarch Theodore I of Constantinople removed the pope's name prior to the Third Council of Constantinople. At the council Peter was condemned as a heretic along with Patriarchs Sergius I, Pyrrhus and Paul II all of Constantinople, Patriarch Cyrus of Alexandria, and Theodore of Raithu.
