3rd July (NS) — 20th June (OS) 2025
ADALBERT of MAGDEBURG, a monk at the Abbey of St. Maximin (abtei St. Maximin) in Trier in the present-day German state of Rhineland-Palatinate, and missionary bishop. At the request of St. Olga, the Princess of Russia, in 961 St. Adelbert led a group of missionaries to evangelise the Slavs. There they met great resistance led by St. Olga’s son Svyatoslav, and many of St. Adelbert’s companions were slaughtered. The survivors, including St. Adalbert, escaped to Mainz where they spent several years. St. Adalbert was then appointed Abbot of the Abbey of SS. Peter and Paul of Wissembourg (abbaye Saint-Pierre-et-Saint-Paul de Wissembourg) in Alsace (eastern France). He was consecrated the first Archbishop of Magdeburg (central Germany) in 968. St. Adelbert founded the dioceses of Naumberg, Neissen, Merseberg, Brandenburg, Havelberg, and Posen, and was made Metropolitan of the Slavs. Known for his strong belief in the importance of education in general, and his monks in particular, St. Adalbert counted SS. Bruno of Querfort (15th October) and Adalbert of Prague (23rd April) amongst his disciples. St. Adalbert reposed 981.
BAGNE (BAIN, BAGNUS) of THÉROUANNE, a monk and disciple of St. Wandrille of Fontenelle (22nd July) at the Abbey of St. Peter / abbaye Saint-Pierre (later the Abbey of St. Wandrille / abbaye Saint-Wandrille) in Fontenelle, Normandy (France). St. Bagne was in 667 consecrated Bishop of Thérouanne, in Artois, Flanders (northern Belgium). After twelve years, St. Bagne resigned his See and returned to Fontenelle Abbey where three years later he was elected Abbot. Towards the end of his life, St. Bagne was appointed to serve as Abbot of the Abbey of St. Benedict on the Loire (abbaye de Saint-Benoît-sur-Loire — Fleury Abbey) as well. St. Bagne reposed circa 710, and is the primary patron-saint of Calais on the English Channel in northern France.
FLORENTINA (FLORENCE) of CARTAGENA, the only sister of SS. Leander of Seville (27th February), Fulgentius of Ecija (16th January) and Isidore of Seville (4th April). St. Florentina was orphaned whilst still young, she was raised by her brother St. Leander. When older, she received monastic tonsure, and eventually served as Abbess of an unknown monastery. St. Florentina reposed circa 636.
GOBAN (GOBAIN) of PICARDY, a disciple of St. Fursey of Péronne (16th January), and companion on St. Fursey’s mission to Gaul (France). St. Goban spent the last years of his life as a hermit in the Voas forest where the present-day town of Saint-Gobain is. St. Goban was martyred by pagan marauders circa 670.
GOVAN (GOVEN, COFEN), St. Govan was most likely an Irishman who had been a disciple of St. Ailbe of Emly (12th September) before he went to Wales. He lived there as an anchorite in a fissure in a cliff at what is now called St. Govan’s Head in Pembrokeshire, Wales. St. Govan is believed to have reposed circa 586 and to be buried under the altar of his hermitage.
HELEN (HELIADA) of OEHREN, second Abbess of the Abbey of St. Mary (Kloster St. Marien) in Oehren, in Trier in the present-day German state of Rhineland-Palatinate. St. Helen reposed circa 750.

GERMANUS of MAN, not to be confused with his better-known namesake, St. Germanus of Auxerre (31st July), St. Germanus of Man was a monk traditionally counted amongst the nephews of St. Patrick of Ireland (17th March). Though there is no reliable information on his life extant, it is believed that after spending time in monasteries in Ireland, Wales, and Brittany (northern France), he was sent to the Isle of Man as a bishop. He reposed circa 474, and his memory is still kept in the British Isles in several place-names including Germain and Jarman.

HELIODORUS of ALTINUM, (Eighth Century), originally from Dalmatia (Croatia), and friend and benefactor of fellow countryman, St. Jerome (30th September). St. Heliodorus, is credited with being especially helpful with the logistics of producing the Vulgate translation of the Bible. He served for a while as Bishop of Altinum, a small town, since destroyed, near Venice (north-eastern Italy). St. Heliodorus is also remembered as a stalwart opponent of Arianism. The exact date of his repose is uncertain, he is recorded as assisting at the first Council of Aquileia in 381, and there is a letter extant from St. Jerome to him dated 396.
IRENAEUS and MUSTIOLA of CHIUSI, St. Irenaeus, was a deacon, and St. Mustiola, a noble lady seemingly related through marriage to Emperor Claudius II(r. 268–270). They were martyred in 273 at Chiusi in Tuscany (central Italy) for ministering to imprisoned Christians, and ensuring proper burials following their martyrdoms.
LEO II, a native of Sicily who was 80th Pope of Rome from 681 until his repose in 683. During his papacy, the former Pope Honorius I (r. 625–638) was censured by the Sixth Œcumenical Council for not denouncing Monothelitism. St. Leo is also credited as the author of several Liturgical Hymns.
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.
