Orthodox Saints of the Pre-Schism See of Rome
AGRICOLA, the seventh Bishop of Nevers in Dijon, from 570 until his repose in 594.
ANDREW of FLORENCE, a Bishop of Florence who reposed circa 407. It is said that his skill at evangelisation was such that he completed eliminated paganism in his See.
DIONYSIUS of AUGSBURG, the first Bishop of Augsburg. St. Dionysius was martyred during the Diocletianic Persecution (303–313).
FAUSTINIAN, (Fourth Century), the second Bishop of Bologna. St. Faustinian was a resolute defender of orthodoxy against Arianism, and used his outstanding administrative talents to reorganise his See following the tribulations of the Diocletianic Persecution (303–313).
VICTOR, (Seventh Century), a priest-hermit at Arcis-sur-Aube in Champagne. His sanctity and wisdom brought many to Christ.
Prior to the Schism the Patriarchate of Rome was Orthodox, and fully in communion with the Orthodox Church. As Saint John of Shanghai and San Francisco +1966 said “The West was Orthodox for a thousand years, and her venerable Liturgy is far older than any of her heresies”.
In many cases there are several spelling versions of the names of saints from the British Isles. I use the Oxford Dictionary of National Biography version as the primary version with the more prevalent version in parenthesis e.g. Ceadda (Chad) of Lichfield.
