Orthodox Saints of the Pre-Schism See of Rome
CAIDOC and FRICOR (ADRIAN), two seventh century Irish missionaries, who went to north-eastern Gaul where they evangelised the Morini tribesmen. SS. Caidoc and Fricor’s mission was extremely fruitful, and amongst those brought to Christ was St. Richardius (26th April).
CELLACH (CEILACH, KEILACH, CELLACH mac SÓERGUSSA), (Ninth Century), a member of the re-founding group of the Abbey of Kells, Co. Meath, Ireland, prior to his elevation to the See of Armagh. Whilst in his Acta Sanctorum Hiberniae the noted hagiographer and historian John Colgan O.F.M. (†c. 1657) numbers at least thirty-three Celtic saints named Cellach or Ceilach, it is most likely that this St. Cellach was an Abbot of Iona, prior to his consecration as Bishop of Armagh.
DODOLINUS, (Seventh Century), the thirty-seventh Bishop of Vienne in south-eastern present-day France.
TEWDRIG ap TEITHFALLT, Welsh king who abdicated in favour of his son, to live as a hermit. Martyred during a Saxon invasion in 630.
THEODORA, the sister of St. Hermes (28th August) to whom she provided material and emotional support during St. Hermes imprisonment and torture. The Acta of Pope St. Alexander I (3rd May) state that St. Theodora also buried St. Hermes (28th August) following his martyrdom. St. Theodora, herself, was martyred soon after. SS. Theodora and Hermes were buried side by side, circa 125.
VENANTIUS, a bishop in the Dalmatia region of present-day Croatia. St. Venantius along with several companions, was martyred in the mid- third century.
VALÉRY (GUALARIC, WALERICUS) of LEUCONE, a monk at the Abbey of SS. Peter and Paul of Luxeuil (abbaye Saint-Pierre et Saint-Paul de Luxeuil), who went on to found the Abbey of Leuconay at present-day Saint-Valery-sur-Somme, France. St. Valéry reposed circa 622.
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.
