Orthodox Saints of the Pre-Schism See of Rome
ARTEMIUS (ARTHEMIUS), a Royal Imperial Legate, who, whilst traveling through Gaul on a mission to Spain, fell ill. He then settled in Clermont in the Auvergne, and his sanctity is said to have been such that he was chosen to be the sixth Bishop of that Diocese. St. Artemius reposed in 396.
BERTRAND (BERTRAM, BERTRAN, EBERTRAM), (Seventh Century), a friend and disciple of St. Bertin (5th September), who also assisted St. Omer (9th September) enlighten northern Gaul and Flanders, and later became Abbot of the Abbey of Mont Saint-Quentin in Picardy.
CADOG (CADOC, CADFAEL, CATHMÁEL, CADOCUS), St. Cadog was a son of St. Gwynllyw (29th March), King of Gwynllwg in South Wales, and Gwladys, the daughter of King St. Brychan of Brycheiniog (6th April), and a nephew of St. Petroc (4th June). He founded the famous monastery of Llancarfan in Glamorgan, which grew to be an illustrious nursery of holy men. Accompanied by St. Gildas (29th January), he assumed an hermetic life on an island off the coast of Vannes in Brittany. After several years, he returned to Britain, settling in the settled in the Eastern counties, and, it is believed, taking spiritual charge of the Britons. St. Cadog was martyred by the conquering Saxons circa 580, near Weedon in Northamptonshire.
EXUPERANTIUS, (Fifth Century), an early Bishop of Cingoli, approximately 35 km / 22 mi South-West of Ancona, in the Marches, present-day Italy. It is generally accepted that St. Exuperantius was a native of Northern Africa.
FELICIAN, a disciple of Pope St. Eleutherius (26th May), who later priested him. St. Felician was consecrated Bishop of his native city of Foligno by Pope St. Victor I (28th July). He served that See, and for a while was the only bishop in northern Italy, until his martyrdom in 250. During the Decian Persecution St. Felician was arrested, tortured, and martyred. He was originally buried at Foligno, though his relics were translated to Metz, France, in October of 970.
GUASACHT, (Fifth Century), the son of the Chieftan Maelchu, St. Patrick's (17th March) master when he was enslaved in Ireland. St. Guasacht was converted by St. Patrick, and eventually became one of his fellow workers in the conversion of the Irish, and ultimately was consecrated Bishop of Granard (Co. Longford).
SURANUS, the abbot of a monastery at Sora near Caserta in present-day Lazio, Italy. During the Lombard invasion, St. Suranus exhausted the whole of the monastery's wealth aiding refugees. As a result, when the Lombards reached the monastery and found nothing left to loot, they they martyred Suranus on the spot circa 580. In his Dialogues, St. Gregory the Dialogist (3rd September) was unambiguous in his praises of St. Suranus.
ZAMA, though he is generally considered to have been the first Bishop of Bologna, many, pace ecclesiastical historian Caesar Cardinal Baronius (†1607), maintain that Bologna's importance as a city, would mean it was a Bishopric much earlier. St. Zama is said to have been consecrated by Pope St. Dionysius (26th December), and to have reposed just prior to the commencement of the Diocletianic Persecution, circa 268.
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.
