Orthodox Saints of the Pre-Schism See of Rome
CALIMERIUS of MILAN, Apostle of the Po Valley, though there are several legends regarding the life of St. Calimerius, all that is certain is that he was a bishop whose relics were enshrined in Milan’s Basilica di San Calimero, and in all likelihood his episcopate was in the late third century, not the second as is often reported.
FABIUS of CAESAREA, a Christian soldier beheaded in 300 at Caesarea in Mauretania Caesariensis (present-day Cherchell, Algeria), during the Diocletianic Persecution, for refusing to carry a standard bearing idolatrous emblems, and stating his faith in Christ as the reason for his refusal.
FIRMUS of TAGASTE, (Date Unknown), praised by St. Augustine of Hippo (28th August) for the steadfastness of his faith, St. Firmus was a Bishop of Tagaste in north-eastern Numidia (present-day Algeria), who endured horrifying torture for refusing to reveal the hiding-place of a fellow Christian.
GERMANUS of AUXERRE, a native of Auxerre in Burgundy (east-central France), and one-time governor of part of Gaul (France), who went on to serve as Bishop of his city of birth. He made two visits to Britain, the first to help combat Pelagianism (possibly accompanied by St. Lupus of Troyes), and a second trip where he is said to have consecrated St. Dubricius (14th November) to the episcopacy, and possibly ordained St. Illtyd (6th November) to the priesthood. St. Germanus reposed whilst attending to Church matters in Ravenna in 448.
NEOT, (Ninth Century), St. Neot is the subject of an eleventh century Life, according to which he was a monk at Glastonbury Abbey in Somerset, England and either a relative or councillor of St. Alfred the Great, King of Wessex (r. 871–886) and King of the Anglo-Saxons (r. 886–899) (26th October). St. Neot retired to a hermitage in Cornwall, England. In time, a group of disciples gathered around him; this community grew into present-day St. Neot, Cornwall. He is thought to have reposed circa 880, and was buried at St. Neot, Cornwall, though some of his relics were later translated to the town now called St. Neots in Cambridgeshire England.
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.
