While rereading J.N.D. Kelly's Early Christian Creeds, something 'caught my eye' which did not make much of an impact during my earlier readings. On page 194, Kelly penned:
It has become, for example, common place to say that Eastern creeds differ from Western in being "more theological".
He then reflects on a few of those differences; but on the next page, he gets to the real 'meat' of the issue, writing:
But the differences between Western and Eastern formularies can be catalogued more precisely. So far as the first article is concerned [i.e. God the Father], R [the Old Roman Creed] stands apart from later creeds because of its failure to emphasize the oneness of God the Father...Almost without exception the Eastern practice is to assert belief in ONE GOD THE FATHER ALMIGHTY, and to describe Him as MAKER OF ALL THINGS VISIBLE AND INVISIBLE or something of the kind. (Page 195)
Moving on, the later, so-called Apostles Creed (which most patristic scholars believe to be an expansion/revision of the Old Roman Creed) also fails "to emphasize the oneness of God the Father".
Continuing this 'tradition', Pope Damasus I (366-384), in what has been termed the Tome of Damasus (a collection of 24 canons composed at a council held at Rome in 382 A.D.), anathematized those who, believed in the Father as the "one God".*
Now, it sure seems to me that this contradicts the Nicene Creed (both 325 and 381) which clearly states that, "We believe in one God, the Father Almighty".
Perhaps I have missed something; if I have, I sincerely hope that our Catholic brothers in Christ (and anyone who thinks I have misread the data at hand) will offer their thoughts on this issue.
