The Lateran Council condemned the Council of Hieria and anathematized its iconoclastic rulings.
The Lateran Council of 769 was a synod held in the Basilica of St. John Lateran to rectify perceived abuses in the papal electoral process which had led to the elevation of the Antipopes Constantine II and Philip. It also condemned the rulings of the Council of Hieria. It is perhaps the most important Roman council held during the 8th century.
