My understanding is that Rome was not invited to the Council of Nicea, and that it took 25 years for Rome to even get the documents of the Council, including, as it turns out, the Creed. So, in retaliation, Rome expressed its displeasure by revising the Creed without consulting the East.
Rome was represented by a presbyter and two deacons.
Quite so! Whatever that other poster was given to understand is complete myth. Probably not his fault, I just cannot imagine how such misinformation would have started in the first place.
Many bishops or representatives from the West were present.
In fact very prominently present was bishop Ossius, who functioned as an aide and counselor to the Emperor. Ossius had been a leading force behind the local/regional Council of Elvira, in Hispania 309AD and was experienced in the organizing of such gatherings. It seems to have been Ossius who advised that the emperor call the Council at Nicea later, and arranged the details. He was bishop of Corduba, then the capital of the Roman province of Hispania Baetica (about as far west as can be imagined in those days).
Constantine was emperor of the west for years before he obtained control of the east, and he was already showing a strong interest in affairs of the church. He called a Council at Arles (now in France) in the year 314AD, fully ten years before Nicea. The main concern at the time was Donatism (Arianism did not loom as a problem at this time). I believe that Ossius was assisting the emperor by then.
Constantine had no way to call the eastern bishops to attend Arles in 314AD, because he was not in control of the east. He would not have political/military control of the east as well as the west until 324AD.
After Constantine defeated the eastern emperor (Licinius) in a fairly bloody series of engagements, he had the eastern bishops meet at Antioch
that same year, this time the main topic of concern was the teaching of Arius. Before long the bishops of that council advised Constantine through Ossius that a council of the entire church of the empire (oikoumene)should come together, the problem of Arianism to continue being the main topic of discussion!
So Constantine, with the help of Ossius of Corduba, called a general council to be held at the imperial palace at Nicea (the new city of Constantinople being somewhere between the architectural stage and early construction), and moved the participants of the Council of Antioch to that alternate location.
Invitations went out from Constantine and Ossius to all the bishops in the empire, to Armenia and other places outside the political reach of Constantine.
Significantly, although the main concern was Arianism the Council did not resort to such terminology as the filioque when constructing the Creed (actually a reworking of baptismal formulae already in use). They clearly avoided it.
Let us remember that this is the creed that the Latin Church has held to be the basis of our faith for 1,700 years. Why then would we be calling for it’s revision in our troubled times?
The Nicene Creed was first chanted with Filioque in Rome in 1014. Many popes before that had tried to suppress this addition.
Also historically correct and accurate.
