Orthodox Saints of the Pre-Schism See of Rome
BENEDICT (BENOÎT) of MASSERAC, originally an abbot at the monastery in Petras (south-western Jordan), St. Benedict travelled west settling in Masserac near Nantes (Upper Brittany, western France). There he lived as a hermit. In time, the number of disciples who gathered round him were such to necessitate a monastery, which he built and served as abbot. St. Benedict reposed in 845.
BERTHARIUS of MONTE CASSINO, a scion of the Capetian dynasty, St. Bertharius left the world and entered St. Benedict of Nursia's (21st March) monastery at Monte Cassino. In 856 he was selected to serve as Abbot of Monte Cassino, and in 844, along with several of his monks, was martyred by Saracens, whilst at prayer.
DONATUS of FIESOLE, an Irishman well known for his piety and erudition. Whilst returning from a pilgrimage to Rome circa 824, St. Donatus and his disciple St. Andrew of Fiesole (22nd August) passed though Tuscany (central Italy), where, due to his renown, he was selected, by popular acclaim, to be Bishop of Fiesole near Florence. St. Donatus served the See of Fiesole for some fifty years, reposing circa 874.
LEOTHADIUS (LÉOTHADE) of AUCH, a Frankish noble who received monastic tonsure at the Abbey of St. Peter (abbaye Saint-Pierre de Moissac) in the Duchy of Aquitaine (south-western France), later serving as its Abbot. In 691, St. Leothadius was consecrated Bishop of southwestern France, serving until his repose in 718. St. Leothadius's relics are enshrined in the crypt of the Cathedral Basilica of Saint Mary of Auch (Basilique Cathédrale Sainte-Marie d'Auch).
MAROVEUS of PRECIPIANO, a monk at the Abbey of St. Columbanus at Bobbio, in present-day Emilia-Romagna, Italy. St. Maroveus went on to found an abbey at Precipiano near Tortona in Piedmont (north-western Italy). He reposed circa 650.
MELLON, St. Mellon, or Milanius as he is styled in the Roman Martyrology, is the subject of many traditions with little factual basis. It is commonly believed he was a native of Wales or Cornwall, and whilst in Rome, was sent to evangelise northern Gaul. There he founded and served as the first Bishop of the See of Rouen (Normandy north-western France). St. Mellon is said to have been a wonderworker, and following a long and fruitful episcopacy, retired to live as a hermit until his repose on 11th November, 314.
MODERAN (MODERAMNUS, MORAN) of RENNES, Consecrated seventh Bishop of Rennes in Brittany (north-western France), in 703, St. Modern ruled that See until circa 720. In that year, he resigned his See, made a pilgrimage to Rome, and spent the rest of his years as a hermit at Berceto in present-day Emilia-Romagna, Italy, reposing circa 730.
NEPOTIAN (NEPOTIANUS) of CLERMONT, the fifth Bishop of Clermont, in the Auvergne region of present-day France, from circa 386 until circa 388.
NUNCTUS (NOINT) of MÉRIDA, a seventh century abbot of a monastery near Mérida (western central Spain). Bandits murdered St. Nunctus in 668, and he has been venerated as a martyr ever since.
NUNILO of HUESCA and ALODIA of HUESCA, daughters of a Muslim father and Christian mother, who were raised as Christians in Huesca, Emirate of Córdoba (southern Spain). After being widowed, their mother married again, also to a Muslim. Their stepfather treated them with great brutality, and ultimately turned them over to the authorities, who imprisoned them. SS. Nunilo and Aldodia were beheaded in 851 in the persecution of Christians during the reign of Emir Abd ar-Rahman II (r. 822–852).
PHILIP of FERMO, little is known about St. Philip, aside from serving as Bishop of Fermo (central Italy). It is commonly accepted that St. Philip was martyred, circa 270, in the persecution of Christians during the reign of the Emperor Aurelian (r. 270–275). His relics are enshrined in the Cathedral of the Assumption of the Virgin Mary (Cattedrale metropolitana di Santa Maria Assunta in Cielo) in Fermo, Italy.
VALERIUS (VALIER) of LANGRES, an early fifth century deacon and disciple of Desiderius of Langres (23rd May). St. Valerius worked to spread the Gospel amongst the pagans in Langres (north-eastern France) and its environs. St. Valerius was martyred on 22nd October, 411 by Vandals who beheaded him near Besançon, (eastern France).
VERECUNDUS, a Bishop of Verona (northern Italy) who reposed in 522. No further details of his life are extant.
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.
