Orthodox Saints of the Pre-Schism See of Rome
ALPHEGE the ELDER, he was called the Elder to distinguish him from his more famous namesake, St. Alphege the Martyr of Canterbury and Greenwich (19th April). St. Alphege was a monk of singularly holy life, and encouraged many others to become monks, notably his relative St. Dunstan (19th May), whom he ordained priest. St. Alphege succeeded St. Birnstan (4th November) in the See of Winchester in 935, serving until his repose from natural causes in 951. His relics were enshrined at Winchester.
MAMILIAN (MAXIMILIAN), a third century martyr in Rome of whom nothing further is known.
MAXIMILIAN, when called-up for military service, St. Maximilian refused to serve on the grounds military service was inconsistent with his faith. As a result, he was beheaded in 295 at Thebeste in Numidia (present-day Algeria).
MURA MCFEREDACH (MURAN, MURAMES), St. Mura McFeredach was the first Abbot and patron saint of Fahan, on the Inishowen Peninsula, in Co. Donegal, Ireland. His staff and bell were held to have miraculous powers and were greatly venerated. The exact year of St. Mura McFeredach's repose is unknown, other than it was sometime in the seventh century.
PAUL AURELIAN, a Romano-Briton prince who was educated at St. Illtyd's (6th November) monastery and school (Cor Tewdws), in present-day Llantwit Major, Glamorgan, Wales with SS. David (1st March), Gildas the Wise (29th January), Illtyd (6th November), and Samson (28th July). After his time at Cor Tewdws, St. Paul, along with twelve other monks, went to Brittany where they established a monastery at Porz-Pol on the Isle of Ouessant. Later St. Paul was convinced to accept elevation to the Bishopric of Ouismor, now known as Saint-Pol-de-Léon, Brittany, France. St. Paul reposed circa 575.
PETER the DEACON, disciple, secretary, and companion of St. Gregory the Dialogist (3rd September). St. Gregory dictated the first four books of his Dialogues to St. Peter. St. Peter reposed circa 605.
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.
