Orthodox Saints of the Pre-Schism See of Rome
ANGADRISMA (ANGADRÊME) of BEAUVAIS, following education at Thérouanne Abbey (northern France) under the direction of St. Omer (9th September), and her cousin St. Lambert of Lyons (14th April), St. Angadrisma received monastic tonsure from St. Audoenus of Rouen (24th August). Ultimately, she became Abbess of the Abbey of Oroër-des-Vierges which was near Beauvais in Picardy (northern France). St. Angadrisma reposed circa 695–698.
BERNARD of ARCE, most likely a native of the British Isles, following a pilgrimage to the Holy Land and Rome, St. Bernard settled as a hermit in Arpino in Lazio (present-day Italy). His relics are enshrined in Rocca d'Arce about 100km / 62mi south-east of Rome.
BURCHARD of WÜRZBURG (BURKARD), an Anglo-Saxon priest from Wessex and disciple of St. Boniface of Mainz (5th June), who joined St. Boniface on his mission to the Germans. Consecrated first Bishop of Würzburg in Bavaria (southern Germany) in 741, St. Burchard was highly successful in spreading the Gospel and oversaw the founding of several monasteries whilst Bishop. He reposed circa 754 and was buried at Mount Saint Mary’s (Old Würzburg). In 983 St. Burchard's relics were translated to the Abbey of St. Andrew at Würzburg, which was later renamed in St. Burchard’s (Kloster St. Burkard) honour.
CALLISTUS (CALLIXTUS) I, ordained to the deaconate by Pope St. Zephyrinus (26th August) who placed him in charge of caring for the Christian burial grounds on the Via Appia (later named the cemetery of San Callistus). Upon the repose of St. Zephyrinus in 217, St. Callistus was elected his successor by popular acclaim. As Pope of Rome, he excommunicated Sabellius, though in general, was compassionate towards repentant sinners, establishing the practice of the absolution of all repented sins. It seems most likely that St. Callistus was martyred circa 222 at Todi in Umbria (central Italy).
DONATIAN (DONAS) of REIMS, a native of Rome, St. Donatian was consecrated in 360 the seventh Bishop of Reims (north-eastern France) in 360, and served that See until his repose in 390. In the mid-ninth century St. Donatian's relics were translated from the Royal Abbey of St. Peter of Corbie (abbaye royale Saint-Pierre de Corbie) in Picardy (northern France) to Bruges (north-west Belgum), where they were enshrined in the cathedral church which now bears his name. St. Donatian is the patron saint of Bruges, Belgium.
FORTUNATUS of TODI, the patron saint of Todi in Umbria (central Italy), St. Fortunatus was a sixth century Bishop of that See, who, according to tradition protected Todi during a siege by the Goths. St. Gregory the Dialogist (3rd September) took great interest in St. Fortunatus’ life, called him a man of great virtue. St. Fortunatus reposed in 537, his relics are enshrined in the church of San Fortunato in Todi.
GAUDENTIUS of RIMINI, originally from Ephesus (present-day Selçuk, Turkey), St. Gaudentius became a Christian and was later ordained to the Priesthood in Rome. In 346 he was consecrated Bishop of Rimini (northern Italy), St. Gaudentius was a participant of Council of Rimini of 357. He was martyred by Arians in 360.
JUSTUS (JUST) of LYONS, (Also 2nd September), a deacon in Vienne (south-eastern France) who in 350 was consecrated the 13th Bishop of Lyons (east-central France). St. Justus was one of the participants at the Council of Aquileia (381) which dealt with Arianism. Shortly after the council, St. Justus resigned his See and, with his deacon, went to Egypt where he lived as a hermit until his repose in 390. Shortly after his repose, his body was brought back to Lyons where he was buried at what came to be the Basilica of Saint-Just.
MANACCA (MANAKUS, MANACCUS), a sixth century Abbot of Holyhead in Wales, and a contemporary of St. Cybi of Caernarvon (8th November). From the information available it appears that he spent his later years in Cornwall.
MÉNEHOULD (MANEHILDIS), one of six or seven sisters, all of whom are venerated as saints in the present-day Champagne-Ardenne region in north-western France. St. Ménehould was a hermit and is the patron saint of the town of Sainte-Menehould in the Champagne-Ardenne region. She reposed circa 490.
RUSTICUS of TRIER, the twenty-seventh Bishop of Trier in the present-day German state of Rhineland-Palatinate. St. Rusticus was forced to resign his See following accusations of sexual impropriety (possibly from his youth). He retired to St. Goar of Aquitaine's (6th July) hermitage where the present-day town of Sankt Goar-Oberwesel in Rhineland-Palatinate, Germany is located. St. Rusticus reposed at the hermitage in 574.
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.
