Oriental Orthodoxy is the faith of those Christian churches which as a rule recognize only the first three ecumenical councils – the First Council of Nicaea, the First Council of Constantinople, and the First Council of Ephesus. The Assyrian church (The Church of the East) recognizes the First Council of Nicaea and the First Council of Constantinople as legitimate ecumenical councils, other councils being the respected councils of its sister Latin church and Eastern Orthodox churches in the West. There are approximately 84 million adherents worldwide.
