Council of Constantinople - 867 (Against Filioque)

867 - Council of Constantinople, convened by Roman Emperor Michael, presided over by Patriarch Photius of Constantinople, and attended by 500 fathers from East and West (the Westerners were the Archbishops of Treves, Cologne and Ravenna). The Council condemns and deposes Pope Nicholas of Rome on the charges of introducing the heretical filioque clause in the creed, as used by the Pope's missionaries in Bulgaria, and for exercising beyond his authority by interfering in dioceses outside his jurisdiction. Pope Nicholas does not accept his deposition, but dies shortly after his condemnation.
