For ten centuries the Eastern Patriarchates were in complete communion with the Pope

Wrong...there were schisms occurring as early as the second century (Victor, Stephen, and Damascus - later the Acacian [AD 482], one under Patriarch Photios I of Canstantinople [AD 866], and continued through the Great Schism of 1054. It is a myth that there has been harmony amongst the patriarchs of the Early Church.

Perhaps, but we are not discussing administrative authority. My point stands:

The discussion, however, is not about the adminitrative structure but the Church Fathers being Catholic, and in order to refute that you need to find a patristic teaching that is recognized either in the West or in the East, which would be contrary to Catholicism.
