Orthodox Saints of the Pre-Schism See of Rome
OSWALD of WORCESTER, (in non-leap years 28th February), the nephew of St. Oda of Canterbury (2nd June) under whom he began his studies. St. Oswald later went to the Abbey of St. Benedict on the Loire (abbaye de Saint-Benoît-sur-Loire — Fleury Abbey) to continue his studies and receive monastic tonsure, and ultimately, ordination to the priesthood. Returning to England, St. Oswald was consecrated Bishop of Worcester, and worked with SS. Dunstan (19th May) and Æthelwold (1st August), with enormous success, to revive monastic life, and religious discipline in Anglo-Saxon England. He personally founded monasteries at Ramsey and Worcester, and was subsequently promoted to the Archbishopric of York (972). St. Oswald reposed whilst on his knees engaged in his daily practice of washing the feet of twelve poor people, circa 990.
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.
