Orthodox Saints of the Pre-Schism See of Rome
ANTIMUS, an eighth century Abbot of The Abbey of St. Peter of Brantôme (L'abbaye Saint-Pierre de Brantôme) in south-western Gaul.
BRIGID and MAURA, (Date Unknown), two daughters of a Scottish chieftain who, whilst on a pilgrimage to Rome, were martyred in Picardy. However, there is some question as to the veracity of their legend.
CANNERA (CAINDER, KINNERA), St. Cannera was an Irish holy virgin who, from an early age, lived as an anchoress near Bantry Co. Cork. After receiving a vision of St. Senan’s (8th March) sanctity, she sought him out, and, having received Holy Communion at his hands, reposed circa 530. She was buried at St. Senan’s monastery on Scattery Island (Inis Cathaigh).
FLAVIAN, a Roman Prefect (or possibly Deputy-Prefect) who converted to Christianity and was martyred at Civitavecchia (approximately 50 km / 30 mi north-west of Rome) during the Diocletianic Persecution circa 300–304.
GLASTIAN, St. Glastian was a Scottish bishop who acted as a mediator between the Picts and the Scots during their last civil war. Serving as the comforter, spiritual father, and charitable protector of many thousands of both nations, he did much to alleviate the suffering of the Picts under the subjugation of the Scots. He reposed 830 and is the patron saint of Kinglassie (Cille MoGhlasaidh) in his native Fife, and is venerated in Kyntire as well.
JOHN of REOMAY (JEAN de RÉOMÉ), the Roman Martyrology called St. John "A Man of God", and from an early age, St. John lived as a hermit in present-day Moutiers-Saint-Jean near the Réôme River (approximately 65 km / 40 mi north-west of Dijon). In time many disciples gathered round him, disturbing his solitude. Seeking to continue his life of seclusion, St. John went to the Abbey of Our Lady of Lérins, however, he was ordered to return to his hermitage, and serve as abbot of the community that had gathered. That community came to be known as the Abbey of St. John of Réome (abbaye Saint-Jean de Réome). St. John reposed in 539.
ODO of BEAUVAIS, though St. Odo initially planned on a career in the military, for reasons no longer known, he received monastic tonsure at the Royal Abbey of St. Peter of Corbie (L'abbaye royale Saint-Pierre de Corbie) in Picardy. St. Odo was made Abbot of Corbie in 851, and then consecrated Bishop of Beauvais in 861. St. Odo reposed in 880.
VALERIUS (VALERO), Bishop of Saragossa (Zaragoza) in present-day Spain from 290 to 315. His tenure as Bishop was interrupted when he was arrested and exiled during the Diocletianic Persecution, until the Edict of Toleration (311) permitted his return. St. Valerius reposed in peace in Saragossa in 315.
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.
