The '''Eighth Ecumenical Council''' was a reunion council held at Constantinople in 879-880. This council was originally accepted and fully endorsed by the [[papacy]] in Rome (whose legates were present at the behest of [[Pope]] John VIII), but later repudiated by Rome in the 11th century, retroactively regarding the [[robber council of 869-870]] to be [[ecumenical]]. The council of 879-880 restored affirmed the restoration of St. [[Photius the Great]] to his see and anathematized [[anathema]]tized any who altered the [[Nicene-Constantinopolitan Creed]], thus condemning the [[Filioque]].
