Orthodox Saints of the Pre-Schism See of Rome
ARGYMIRUS of CÓRDOBA, born in Cabra near Córdoba (southern Spain), St. Argymirus was a nobleman and high-ranking official during the rule of Emir Muhammad I of Córdoba (r. 852–886). Deposed from office due to his Christian faith, St. Argymirus received monastic tonsure. However, he was soon charged with blasphemy by the Moors, and martyred on 28th June, 856.
AUSTELL of CORNWALL, (Sixth Century), there is no written Life of this saint extant, though there are two traditions concerning the identity of St. Austell. The first, and more commonly accepted, is that he was a disciple of St. Maine of Bretagne (21st June) during the latter’s time in Cornwall, and later lived as a hermit in the area now known as St. Austell in Cornwall, England. The other, more recent tradition, posits that St. Austell was a woman (Hawystill), one of the daughters of King St. Brychan of Brycheiniog (6th April), who left her name to Aust in South Gloucestershire, England.
BENIGNUS of UTRECHT, a sixth century French Bishop, in all likelihood, of Chartres (north-central France). He seems to have resigned his See and retired to Utrecht (central Netherlands) where his relics were re-discovered in 996.
CRUMMINE, (Fifth Century), St. Crummine was a disciple of St. Patrick of Ireland (17th March), who placed him in charge of a church at Lackan, Co. Westmeath, Ireland. Nothing further is known of his life.
EGILO (EGILON, EIGIL), an Abbot of Prüm in Lotharingia, present-day Diocese of Trier in Germany. St. Egilo served as Abbot of, and undertook the restoration of the Abbey of St. Peter of Flavigny-sur-Ozerain (abbaye Saint-Pierre de Flavigny-sur-Ozerain) (circa 860–866) in present-day east-central France. Lastly, St. Egilo founded (or restored) an abbey at Corbigny in Burgundy (east-central France). St. Egilo reposed in 871.
HEIMRAD, a priest who spent several years on pilgrimages. His detatchment from the world lead to behaviour that might be thought of as that of a Fool for Christ. St. Heimrad lived for a while as a monk at Hersfeld Abbey (abtei Hersfeld) in Hesse (Germany), and spent his final days as a hermit at Hasungen Abbey (Kloster Hasungen) in present-day Burghasungen near Kassel, Germany. St. Heimrad reposed in 1019.
IRENAEUS of LYONS, a disciple of St. Polycarp of Smyrna (23rd February), who, in turn, was a disciple of the Apostle and Evangelist John the Theologian. St. Irenaeus was sent to Gaul (France) by St. Polycarp. There he was consecrated Bishop of Lyons (east-central France) circa 177, and martyred in 200. St. Irenaeus is considered the first of Western Christendom's great theologians and ecclesiastical writers. His Adversus Haereses in which he refutes the various schools of Gnosticism, is a classic of Christian apologetics.
PAPIAS (PAPIUS) the MARTYR, a victim of the Diocletianic Persecution (303–313), St. Papias was martyred circa 303, possibly in Sicily. There is no further information on his life extant.
THEODICHILDIS (TELCHILDIS), a nun at the Abbey of Our Lady of Faremoutiers (Abbaye Notre-Dame de Faremoutiers) in present-day north-central France. St. Theodichildis was later the first Abbess of the Abbey of Our Lady of Jouarre (abbaye Notre-Dame de Jouarre) in Jouarre (north-central France). St. Theodichildis reposed circa 660.
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.
