Orthodox Saints of the Pre-Schism See of Rome
DOMINIC of BRESCIA, an early seventh century Bishop of Brescia in Lombardy. St. Dominic reposed circa 612.
LIBERATUS and BAJULUS, (Date Unknown), martyrs in Rome, of whom nothing further is known.
URSICINUS of CAHORS, tenth Bishop of Cahors in the Languedoc. Often mentioned in the writings of St. Gregory of Tours (17th November), St. Ursicinus reposed circa 585.
URSICINUS of SAINT-URSANNE, a friend of St. Columbanus (2nd February), and fellow missionary to the Jura. St. Ursicinus founded a monastery where the present-day village of Saint-Ursanne, Switzerland is. He reposed circa 625.
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.
