Orthodox Saints of the Pre-Schism See of Rome
BEATUS of BEATENBERG, Apostle of Switzerland, (Date Unknown), according to legend, St. Beatus was baptised in England by St. Barnabas the Apostle (11th June), and later priested by St. Peter the Apostle (29th June). St. Beatus then went, or was sent, to the area of Lake Thun in the the Bernese Oberland in present-day Switzerland. There he lived in a cave above the lake. The mountain was later called Mount Beatenburg in his honour.
GERONTIUS of CERVIA, a Bishop of Cervia near Ravenna (Italy). While returning from a synod in Rome circa 501, St. Gerontius was attacked and martyred on the Flaminian Way at a town called Cagli approximately 30 km (19 mi) south of Urbino (Italy).
GORFOR of LLANOVER, (Date Unknown) , the patron saint of Llanover in Gwent, Wales. Nothing else is known about this saint’s life.
GREGORY of OSTIA, a Cardinal-Bishop of Ostia near Rome. Later St. Gregory served as Papal Legate to the Kingdoms of Spanish Navarre and Old Castile, both part of present-day Spain. He reposed at Logroño, Castile circa 1048.
JOHN of CHÂLON, consecrated the third or fourth Bishop of Châlon-sur-Saône in Burgundy (France) by St. Patiens of Lyons (11th September). St. John reposed circa 475.
SANCTAN of KILL-da-LES, (Sixth Century) St. Sanctan was a Briton who went to Ireland where he was made Bishop of Kill-da-Les / Kill-na-Sanctan, an unknown See which may have been near present-day Dublin. Some sources state he was a son of St. Selyf of Cornwall (25th June), and a brother of St. Cybi (8th November), though there is nothing extant to substantiate this theory.
VINCENT of MONTES, a monk at the Monastery of St. Peter de Montes (Monasterio de San Pedro de Montes) in the Kingdom of León (present-day Spain), and disciple of St. Gennadius of Astorga (25th May) whom he succeeded as Abbot of St. Peter’s. St. Vincent reposed circa 950.
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.
