Orthodox Saints of the Pre-Schism See of Rome
6th August
HARDULF of BREEDON, (Seventh Century), the Church of St. Mary and St. Hardulph (Church of England) in Breedon on the Hill, Leicestershire, England, commemorates St. Hardulph, about whom we know little else. Though he does not appear in any of the Mediæval Kalendars, the Menology of England and Wales avers that St. Hardulph may be the hermit of Breedon mentioned in the ninth century Life of St. Modwenna of Whitby (5th July). Though the traditional feast date for St. Hardulph is 6th August, he is commemorated on the Calendar of the Moscow Patriarchate on 21st August.
HORMISDAS, successor to St. Symmachus (19th July), St. Hormisdas served as fifty-second Pope of Rome from 20th July, 514 until his repose on 6th August, 523. He spent the majority of his papacy working with Emperor Justin I (r. 518–527), and Patriarch John II Cappadocia of Constantinople to end the Acacian Schism.
JUSTUS and PASTOR, two youths, aged only thirteen and nine, who were scourged and beheaded during the Diocletian Persecution at Alcalá de Henares in Spain circa 304. SS. Justus and Pastor are patron saints of both Alcalá and the Spanish capital of Madrid 35 km/22 mi to the south-west.
STEPHEN of CARDEÑA and COMPANIONS, Martyrs of Cardeña, the abbot of a monastery near Burgos in Spain. St. Stephen, and his community of two hundred monks were martyred, in their monastery, by a horde of Moors circa 872.
SIXTUS II (XYSTUS), (on Eastern Calendars 10th August), the twenty-fourth Pope of Rome. He was arrested in 258 along with his deacons Felicissimus and Agapitus; all of whom were tried and martyred. St. Sixtus’ Archdeacon, St. Laurence of Rome (10th August), was arrested, tried, and martyred four days later.
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”.
Details of British Saints excerpted from Orthodox Saints of the British Isles.
Details of continental saints from these sources.
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.
