Orthodox Saints of the Pre-Schism See of Rome
AGAPIUS and COMPANIONS (MARTYRS of CIRTA), a group of clergy and laity martyred in Cirta in Numidia (present-day Tunisia), during the persecutions under Emperor Valerian (r. 253–260). According to the Roman Martyrology those martyred with St. Agapius were: Antonia, Emilian, Secundinus, Tertula, and a woman and twin children whose names are no longer known.
AVA (AVIA) of DENAIN, a niece of Pepin the Short, King of the Franks (r. 751–768), who was miraculously healed by St. Rainfrede (8th October) of blindness which she had suffered since childhood. In time St. Ava, received monastic tonsure at Denain Abbey in Hainaut, present-day Belgium, and later served as its Abbess. St. Ava reposed circa 845.
DANIEL of GERONA, (Ninth Century), according to a legend of suspect veracity, St. Daniel was native of Asia Minor who became a hermit at an unknown location in present-day Spain. He is listed as a martyr, though the circumstances and location of his martyrdom are unknown.
DICHU (DICTINUS), (Fifth Century), St. Patrick's (17th March) first convert in Ireland, St. Dichu was the son of an Irish chieftain and a swineherd in his youth. He gave St. Patrick the land at Saul in Co. Down, Ireland for his first church.
ENDELLION (ENDELIENT, ENDELIENDA) of TREGONY, (Sixth Century?), St. Endellion was one of the daughters of St. Brychan of Brycheiniog (6th April) and sister of St. Nectan (17th June). According to legend she was the Goddaughter of King Arthur. St. Endellion lived as an anchorite in Cornwall, England and is commemorated by the church and village of St. Endellion in northern Cornwall, England.
FIACHAN (FIANCHNE) of LISMORE, (Seventh Century) , St. Fiachan was a monk under St. Carthage the Younger (14th May) at the famous Lismore Abbey in Co. Waterford, Ireland. He is especially remembered for his obedience and gift of prayer.
GUNDEBERT of GUMBER, (Eighth Century), the husband of St. Bertha (1st May) and brother of St. Nivard (1st September). Towards the end of his life, St. Gundebert separated from St. Bertha by mutual consent. He then went to Ireland where he received monastic tonsure. St. Gundebert met his martyrdom when his monastery was sacked by pagans, and he was killed.
PAULINUS of BRESCIA, a sixth century Bishop of Brescia in the northern Italian region of Lombardy. Consecrated circa 524, St. Paulinus served the See until his repose in 545.
SENAN of WALES, (Seventh Century), St. Senan was a hermit in northern Wales about whom there is no information extant.
SEVERUS of NAPLES, an early fifth century Bishop of Naples (Italy). A renowned wonderworker, St. Severus once brought a man back to life, so he could testify on behalf of his wife who was facing unfounded charges. St. Severus reposed in 409.
TORPES of PISA, although the subject of many early Lives, which are almost complete devoid of fact, little is actually known of St. Torpes. As far as is known he was martyred in Pisa, circa 65, during Emperor Nero's (r. 54–68) persecution of Christians. The town of Saint-Tropez in France is named for him.
WILFRID the YOUNGER, after receiving his education at Whitby Abbey in North Yorkshire, England, under St. Hilda (17th November), St. Wilfrid attached himself to St. John of Beverley (7th May). He later succeeded St. John as the last Bishop of York, England, as the See was elevated to an archbishopric during the time of his successor. St. Wilfrid resigned the See in 732, retiring to Ripon Abbey in North Yorkshire, England where he lived until his repose in 744. He was buried at Ripon Abbey, though it is possible his relics were later translated to Canterbury, England in the mistaken belief they were those of his more famous namesake (12th November).
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.
