Orthodox Saints of the Pre-Schism See of Rome
AILBE (ALBEUS, AILBHE) of EMLY, (Sixth Century), St. Ailbe is considered to have been the first Bishop of Emly in Ireland and is said to have reposed circa 527, 534 or 541. Unfortunately, many legends concerning St. Ailbe, all of which are disputed, and some completely unfounded makes it impossible to state with certainty anything further about him.
GUY of ANDERLECHT, “the Poor Man of Anderlecht”, early on St. Guy embraced a life of caring for the sick and poor. After a business venture he invested in failed, St. Guy went on a pilgrimage, first to Rome, then the Holy Land, that lasted seven years. Soon after his return to Anderlecht circa 1012, St. Guy collapsed from exhaustion and illness, and reposed shortly thereafter.
SACERDOS of LYONS, the Archbishop of Lyons (east-central France) from 544 until his repose in 551. St. Sacerdos was a son of St. Rusticus of Lyons (25th April), and father of St. Aurelian of Arles (16th June). As Archbishop he presided over the fifth Council of Orléans held in October 549, and also served as an adviser to Childebert I, King of Paris (r. 511–558).
SILVINUS, a Bishop of Verona (northern Italy), he reposed circa 550, no further information is 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”.
