Held in Constantinople in 553. Under Emperor
Justinian the Great. 165 Bishops were present.
Nestorian and Eutychian Controversies
The Council was called in hope of putting an end to the Nestorian and
the Eutychian (Monophysite) controversies). The Council confirmed
Church's teaching regarding the two natures of Christ (human and divine)
and condemned certain writings with Nestorian learnings. Emperor
Justinian himself confessed his Orthodox faith in a form of the famous
Church hymn "Only begotten Son and Word of God" which is sung
during the Divine Liturgy.
