Orthodox Saints of the Pre-Schism See of Rome
CADFARCH, reputed to have been a member of a family of unspecified saints, St. Cadfarch was a sixth century disciple of St. Illtyd (6th November). He is believed to have founded a church in Penegoes, Powys, Wales, where there is a holy well known as St. Cadfarch’s Well, said to have healing properties.
Troparion of St. Cadfarch
Brother and companion of saints,
O Father Cadfarch, thou art truly numbered
among the Righteous of the Age of Saints.
Wherefore intercede for us, weak as we are,
that Christ our God will grant us great mercy.
EVERGISLUS (EBREGESILUS) of COLOGNE, an early fifth-century Bishop of Cologne in the present-day German state of North Rhine-Westphalia. St. Evergislus was martyred by bandits whilst visiting Tongeren in present-day Belgium.
FELIX (AFRICANUS) of THIBIUCA, AUDACTUS (ADAUCTUS) of THIBIUCA, JANUARIUS of THIBIUCA, FORTUNATUS of THIBIUCA, and SEPTIMUS of THIBIUCA, early victims of the Diocletianic Persecution (303–313). St. Felix, Bishop of Thibiuca in Africa Proconsularis, despite every enticement, refused to surrender Sacred Scriptures to the authorities. As a result, he along with Audactus, Januarius, Fortunatus, and Septimus, were martyred.
FROMUNDUS (FRÉMOND) of COUTANCES, Bishop of Coutances in Normandy (north-western France) from circa 674 until his repose circa 690. Whilst bishop, St. Fromundus founded the women's Abbey of the Our Lady of Ham (abbaye Notre-Dame de Ham) in Ham, in Normandy (north-western France).
MAGLORIUS (MAELOR) of WALES, a native of south Wales and possible relation of St. Samson of Dol (28th July), whom he accompanied to Brittany (north-western France). In Brittany they both became abbots, St. Samson at Dol, St. Maglorius at Lanmeur. Following the repose of St. Samson, St. Maglorius was appointed to succeed him as Bishop of Dol. Later he retired from his See, and went to Sark in the Channel Islands, there he founded a monastery where he lived until his repose circa 575. Later the relics of St. Maglorius were enshrined at the Église Saint-Jacques-du-Haut-Pas in Paris' 5th Arrondissement.
MARCIUS (MARK, MARTIN) of MONTE CASSINO, a hermit at Monte Cassino, whose virtues were acclaimed by St. Gregory the Dialogist (3rd September), and was said to have been a wonderworker by the twelfth century librarian, chronicler, and hagiographer of the Abbey of Monte Cassino Peter the Deacon (†c. 1153). Towards the end of his life St. Marcius left Monte Cassino and spent the rest of his life as a hermit in a cave on Mount Mondragone (southern Italy), where he reposed circa 679.
MARTIN of VERTOU, ordained to the Deaconate, or possibly Priesthood, by St. Felix of Nantes (7th July), St. Martin was noted for being a wonderworker, as well as, being devoid of any skill as a preacher. He founded a hermitage at Vertou south-east of Nantes (Upper Brittany, western France), in time the number of disciples who gathered around St. Martin necessitated founding what came to be the Abbey of St. Martin of Vertou (abbaye Saint-Martin de Vertou), serving as its first Abbot. St. Martin reposed in 601.
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.
