Orthodox Saints of the Pre-Schism See of Rome
AGIA (AIA, AYE), (Sixth Century), mother of St. Lupus of Sens (vide infra), she was a woman of great holiness who has been venerated as a saint since her repose.
ARCANUS, following a pilgrimage to the Holy Land, St. Arcanus founded a monastery to enshrine relics which he had brought back. This monastery grew to become Sansepolcro in Tuscany. He is believed to have reposed circa 1050.
CONSTANTIUS the BISHOP, a Bishop of Aquino (Aquinum) in Lazio (present-day Italy). St. Constantius is mentioned by Pope St. Gregory the Dialogist (3rd September) in his Dialogues, and was known for his gift of prophecy. St. Constantius reposed circa 520.
FIRMINUS of AMIENS, (Fourth Century), named for St. Firminus (25th September), who, as first Bishop of Amiens in Picardy, had baptised his father, this St. Firminus was third Bishop of Amiens.
GILES (ÆGIDIUS, GILLES), (Eighth Century), there is little in the way of reliable information on his life. St. Giles is believed to have been born in Athens, but seems to have gone to what is today Languedoc and Provence in France. There he lived primarily as a hermit, though is said to have founded an abbey in what is now the town of St-Gilles-du-Gard. The tomb in this abbey, which was rededicated to him in the tenth century, became a place of pilgrimage and a stop on the road from Arles to Santiago de Compostela. The cultus of St. Giles quickly spread throughout Europe, with numerous churches and monasteries dedicated to him in Britain, France, Germany, Hungary, Poland, Slovakia, and Spain.
LUPUS (LEU) of SENS, (Seventh Century), a member of the royal house of the Kingdom of Burgundy, who served as the nineteenth Bishop of Sens in Burgundy.
LYTHAN (LLYTHAOTHAW), St. Lythan is the patron saint of two churches in the Diocese of Llandaff in southern Wales. Nothing further, including the years he flourished, is known of his life.
NIVARD of REIMS, Bishop of Reims (north-eastern France) from sometime before 657 until his repose circa 670. St. Nivard is buried at the Abbey of St. Peter (abbaye Saint-Pierre d'Hautvillers) in Hautvillers (north-eastern France), which he had restored.
PRISCUS, according to tradition St. Priscus was one of the Seventy, and that he accompanied the Apostle Peter (29th June) to Italy, and may have been the first Bishop of Capua in Campania. It is believed to have been martyred under Nero, circa 66.
PRISCUS, CASTRENSIS, TAMMARUS, ROSIUS, HERACLIUS, SECUNDINUS, ADJUTOR, MARK, AUGUSTUS, ELPIDIUS, CANION, and VINDONIUS, St. Priscus, was a bishop in North Africa, who along with his priests, was exiled by the Arian Vandals. Finding sanctuary in southern Italy they applied themselves to pastoral work and preaching the Gospel. It is possible that some of them were appointed bishops of the Sees in which they had served.
REGULUS, a native of Africa who was forced into exile by the Arian Vandals. He settled in Tuscany (central Italy), but seems to have been martyred circa 545, when the Arian Totila, King of the Ostrogoths, (r. 541–552) and his army invaded Italy during the Gothic War (535–554).
SIXTUS (XYSTUS) of REIMS, the first Bishop of Reims, there are several traditions about him, but the most likely one says that he founded the Sees of Reims (north-eastern France) and Soissons (northern France), having been sent to evangelise Gaul by Pope St. Sixtus II (6th August). St. Sixtus reposed circa 300. Nothing more can be stated with any certainty about his life.
TERENTIAN, a Bishop of Todi in Umbria (central Italy) who was arrested during the persecution of Christians under Emperor Hadrian (r. 117–138). In 118, after being tortured on the rack, and having his tongue cut out, St. Terentian was beheaded.
TWELVE HOLY BROTHERS, there are two traditions regarding these saints. One is that they are the children of SS. Boniface and Thecla (30th August), and were martyred shortly after their parents. However, there is no reliable account of their martyrdom extant. The other is in 760, the relics of a group of martyrs in southern Italy dating from circa 303, were gathered together and enshrined in Benevento, Italy as a group then called the “Twelve Holy Brothers”.
VERENA of ZÜRICH, (Third Century) a native of Egypt who travelled to Switzerland in search of a relative who was a member of the Theban Legion (22nd September). St. Verena eventually settled as an anchoress near present-day Zürich, Switzerland.
VICTORIUS of LE MANS, sixth Bishop of Le Mans (north-western France) from circa 453, until his repose circa 490. He is said to have been a disciple of St. Martin of Tours (11th November). St. Gregory of Tours (17th November) attested to his miracles and holiness of life.
VINCENT of XAINTES and LAETUS of DAX, (Fifth Century ?), St. Vincent and St. Laetus are martyrs often said to have been natives of Spain. It is equally possible the hailed from present-day south-western France near the Pyrenees mountains. St. Vincent served as the first Bishop of Dax (south-western France), and St. Laetus was his deacon.
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.
