Orthodox Saints of the Pre-Schism See of Rome
ALDO, a Count of Ostrevant, a district in present-day northern France, who flourished in the late eighth century. St. Aldo received monastic tonsure at the double monastery of Hasnon in Picardy (present-day northern France), and later served as its Abbot.
BALBINA, generally accepted to have been the daughter of St. Quirinus (30th March) the martyr. St. Balbina was baptised by Pope St. Alexander I (3rd May). St. Balbina was martyred along with her parents, circa 130.
GUY (GUIDO), rejecting the sybaritism of his youth, St. Guy received monastic tonsure at Pomposa Abbey near Ferrara, Italy. He then spent time at the Abbey of St. Severus in Ravenna, Italy, serving as Abbot towards the end of his stay there. St. Guy returned to Pomposa and was soon after appointed Abbot of Pomposa. During his tenure as Abbot, Pomposa experienced a doubling of the number of monks in the community. St. Guy reposed in 1046.
RENOVATUS, after renouncing the heresy of Arianism, St. Renovatus received monastic tonsure at the Monastery of Cauliana in Lusitania (present-day Portugal). He was later appointed Abbot of Cauliana, and then circa 611 consecrated Bishop of Mérida (present-day Portugal). St. Renovatus reposed circa 633.
THEODULUS, ANESIUS, FELIX, CORNELIA, and COMPANIONS, (Date Unknown), a group martyrs in Africa Proconsularis of whom no further particulars are extant.
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.
