Orthodox Saints of the Pre-Schism See of Rome
AMANTIUS of TIPHERNUM, the patron saint of Città di Castello in Perugia (central Italy), where he served as a priest. Pope St. Gregory the Dialogist (3rd September) revered his sanctity and noted his great wonderworking. St. Amantius reposed circa 600 at Tiphernum (present-day Città di Castello).
COLMÁN ELO (COLMÁN MOCCU SAILNI, COLMÁN MAC BEOGNAI, COLMÁN of ELO), St. Colmán was born in present-day Co. Tyrone in Ireland. He studied under his maternal uncle, St. Columba of Iona (9th June) and went on to found monasteries at Lynally (Lann Elo) in Co. Offaly, Ireland and at Muckmore in Co. Antrim. There he served as founding Abbot-Bishop of Connor. St. Colmán was the author of the Airgitir Crábaid (the Alphabet of Devotion), the earliest surviving example of Old Irish prose. He is believed to be the true author of a work ascribed to St. Seachnall (Secundinus) of Ireland (27th November), The Hymn of St. Secundinus in praise of St. Patrick of Ireland (17th March). St. Colmán reposed circa 610.
EUSEBIUS of BOLOGNA, consecrated sixth Bishop of Bologna (northern Italy) circa 370, St. Eusebius was a discerning and erudite Prelate, and a close friend of St. Ambrose of Milan (7th December). He assisted at the September 381 Council of Aquileia, one of the many of that era held to combat the heresy of Arianism. Through a vision, St. Eusebius discovered the hidden relics of the Martyrs of Bologna, SS. Vitalis and Agricola (4th November), and was responsible for having them reverently enshrined. St. Eusebius reposed circa 400.
MEUGANT (MAWGHAN, MORGAN), (Sixth Century), St. Meugant was a disciple of St. Illtyd (6th November) who seems to have lived as a hermit in several places is the west of Britain before settling on the Isle of Bardsey in Wales. There are several churches in Wales and Cornwall (England) dedicated to him, and though no record of his consecration is extant, St. Meugant has been represented as a bishop with a mitre and crozier.
NILUS the YOUNGER, a monk and fervent advocate for Byzantine monastic practices on the Italian peninsula. St. Nilus was well known for his ascetic ways and theological knowledge. He spent some time as a hermit, and at various monasteries, some of which he either founded or helped restore. During the Saracen invasions St. Nilus and some of his monks took refuge at Monte Cassino. However, his crowning achievement was founding the Abbey of Santa Maria di Grottaferrata at a spot just south-east of Rome which was identified to St. Nilus by the Theotokos. Shortly after the building began, St. Nilus reposed (26th December, 1005) at the Sant' Agata monastery in Tusculum (present-day Frascati) outside of Rome.
SENATOR of ALBANO, (Date Unknown), a martyr at Albano in the present-day Metropolitan City of Rome, Italy.
VIGILIUS of BRESCIA, a Bishop of Brescia in Lombardy (northern Italy) who reposed circa 506. Nothing further is known of his life.
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.
