Orthodox Saints of the Pre-Schism See of Rome
BECAN (BEGAN) of KILL-BEGGAN, one of the ‘Twelve Apostles of Ireland’ (6th January). St. Becan is credited with founding a monastery at Kill-Beggan in Co. Westmeath, Ireland. He also gave his name to the church and parish of Imleach-Becain, Co. Meath, Ireland. The Félire Óengusso (Martyrology of Ængus) lists him along with SS. Enda (21st March) and Cuan (1st January) as ‘three greatest champions of virtue, and leaders of saints of their era’.
DERFEL-GADARN, it is universally accepted that he was a celebrated warrior, and local legend claims St. Derfel-Gadarn was one of seven warriors of King Arthur who survived the Battle of Camlann (537 or 539). St. Derfel-Gadarn entered monastic life later, and spent a period of time as a hermit at Llandderfel in Gwynedd, Wales. The present parish of St. Derfel (Church of Wales) is located on the site believed to have been where St. Derfel-Gadarn had his hermitage. Always held in great veneration by the Welsh, St. Derfel-Gararn reposed in the late sixth century.
MARTYRS of NORTH-WEST AFRICA, an unknown number martyred in 459 during the Easter liturgy, by order of the Arian Gaiseric, King of the Vandals (r. 428–477).
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.
