There were 9 Ecumenical Synods. This notion of only 7 is the result of Jesuit propaganda during the Turkish years. The Papists do not want the Orthodox to commemorate the 8th and 9th Synods because they explicitly anathematize Papist beliefs. The 8th Synod (879) condemned the “filioque” and the 9th Synod (1351) condemned the theology of Thomas Aquinas and upheld the theology of St. Gregory Palamas.
The Encyclical of the Eastern Patriarchs (1848) which was signed by all four patriarchs (Constantinople, Alexandria, Antioch, and Jerusalem) as well as their Holy Synods explicitly refers to the Council of 879 as the “Eighth Ecumenical Synod”.
