Orthodox Saints of the Pre-Schism See of Rome
CATHAN (CATAN, CHATTAN, CADAN) of BUTE, (Sixth Century), St. Cathan, an uncle of St. Blane (10th August), was an Irish missionary who appears to have been a bishop on the Isle of Bute (Scotland) in the sixth, or possibly seventh century. the noted hagiographer and historian John Colgan O.F.M. (†c. 1657) tells of the discovery of St. Cathan’s tomb at Tamlacht near Londonderry, Ireland, though the Aberdeen Breviary claims his relics are on the Isle of Bute, which has been known as Kil-cathan in his honour.
HERADIUS, PAUL, AQUILINUS, and COMPANIONS (MARTYRS of NYON), an unknown number of Christians, of whom only these three names are known. All were martyred circa 303 at Noviodunum (present-day Nyon, Vaud, Switzerland) during the Diocletianic Persecution.
MADEN (MADERN, MADRON) of CORNWALL, (Date Uncertain), St. Maden was a hermit in Cornwall, England who spent a period of time in Brittany (France), where there are several churches dedicated to him. St. Madern’s Well in Cornwall marks the reputed site of his hermitage, and is still a place of pilgrimage.
MAILDUF of MALMESBURY, (Seventh Century), St. Mailduf, a native of Ireland, travelled to England and founded the great Abbey of SS. Peter and Paul at Malmesbury in Wiltshire. Malmesbury was one of the few monastic houses in England able to maintain a continuous presence from its founding until the Dissolution of the Monasteries in England and Wales (1536–1540) by Henry VIII, King of England and Ireland, (r. 1509–1547), and it is where St. Aldhelm (25th May) was trained. St. Mailduf reposed in 673.
RASSO (RATHO) of GRAFRATH, a Bavarian count and soldier, who fought invading Hungarians. St. Rasso went on a pilgrimage to the Holy Land, and then Rome. Upon returning to Bavaria, St. Rasso founded a monastery where present-day Grafrath, Fürstenfeldbruck, Bavaria, Germany is. St. Rasso spent the rest of his life living as a simple monk at the monastery he had founded, and reposed in 953.
RESTITUTA of CARTHAGE, a maiden who was martyred circa 304 near Carthage, Africa Proconsularis (in present-day Tunisia), during the Diocletianic Persecution. According to tradition, St. Restituta was put on a burning boat which was left to drift in the sea. The boat then drifted to Italy, where her relics are thought to be enshrined at the Cathedral of St. Januarius (Duomo di San Gennaro) in Naples.
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.
