== Ecumenical? ==
This council is not regarded as ecumenical by all Orthodox Christians, but some major voices in the Orthodox world do so, including 20th century theologians Fr. [[John S. Romanides]] and Fr. [[George Metallinos]] (both of whom refer repeatedly to the "Eighth and [[Ninth Ecumenical Council]]s"), Fr. [[George Dragas]] and Metropolitan [[Hierotheos (Vlachos) of Nafpaktos]].
Further, the [[Encyclical of the Eastern Patriarchs]] refers explicitly to the "Eighth Ecumenical Council" regarding the synod of 879-880 and was signed by the [[patriarch]]s of [[Church of Constantinople|Constantinople]], [[Church of Jerusalem|Jerusalem]], [[Church of Antioch|Antioch]], and [[Church of Alexandria|Alexandria]] as well as the [[Holy Synod]]s of the first three.
