Eastern Orthodox argue that the First Council of Ephesus canon 7 explicitly prohibited modification of the Nicene Creed by any man (not by ecumenical church council) drawn up by the first Ecumenical Council in 325. In reality, the Council made no exception for an ecumenical council or any other body of bishops, and the Greeks participating in the Council of Florence emphatically denied that even an ecumenical council had the power to add anything to the creed. The creed quoted in the Acts of the Council of Ephesus of 431 (the third ecumenical council) is that of the first ecumenical council, that of Nicaea (325), without the modifications that the second ecumenical council, held in Constantinople in 381, is understood to have made to it, such as the addition of "who proceeds from the Father". Eastern Orthodox theologians state this change of the wording of the churches' original creed, was done to address various teachings outside of the church in specific the Macedonius I of Constantinople teaching which the council claimed was a distortion of the church's teaching on the Holy Spirit. This was not a change of the orthodoxy of the churches' original creed. Thus the word in the seventh canon of the later Council of Ephesus is understood as meaning "different" or "contradictory" and not "another" in the sense of mere explanatory additions to the already existing creed. Some scholars hold that the additions attributed to the First Council of Constantinople were adopted only with the 451 Council of Chalcedon, 20 years after that of Ephesus, and even that the Council of Ephesus, in which Alexandrian influence was dominant, was by this canon excluding the Constantinopolitan Creed, which eventually annexed the name and fame of the creed adopted at Nicaea.
