Orthodox Saints of the Pre-Schism See of Rome
ÆTHELBERT (ETHELBERT, ALBERT, ALBRIGHT) of EAST ANGLIA, St. Æthelberht was King of East Anglia in England (r. c. 779–794). He was treacherously murdered in 794 by order of King Offa of Mercia (r. 757–796) who had invited St. Æthelberht to his Court under the pretext of marrying his daughter. He was immediately venerated as a martyr especially in Hereford, England where his relics were entombed, and in his native East Anglia.
ANASTASIUS of BRESCIA, a Bishop of Brescia in Lombardy (Italy), who played a significant role in the conversion of the Arian Lombards to orthodox Christianity. St. Anastasius reposed in 610.
AUSTREGISILUS (AOUSTRILLE, OUTRILLE) of BOURGES, a courtier at the court of Gontram, King of Burgundy (r. 561–592) court at Chalon-sur-Saône (eastern France). St. Austregisilus felt called to monastic life and entered the Abbey of St. Nizier (abbaye Saint-Nizier de Lyon) in Lyons (east-central France), receiving monastic tonsure, and ordination to the priesthood. St. Austregisilus was soon made Abbot of St. Nizier, and in 612 was consecrated Bishop of Bourges (central France). He served that See until his repose 624. St. Austregisilus was mourned by his flock who quickly venerated him as a saint, which received Episcopal approval not long after.
BASILLA (BABILLA) of ROME, there seems to be a bit of confusion about this (these) saints, some martyrologies list either St. Basilla or Babilla, some both as separate saints, while others posit they are the same saint. The extant Acts are completely unreliable. The majority opinion is that St. Basilla was a niece of Emperor Gallienus (r. 253–268), who secretly converted to Christianity. When discovered, she was given the choice between marrying a pagan patrician (thus renouncing her faith), or martyrdom. St. Basilla chose martyrdom, and was beheaded in Rome, circa 270 or circa 304.
BAUDELIUS of NÎMES, (Second or Third Century), a married lay evangelist who indefatigably laboured to spread the faith in Gaul (France). St. Baudelius was martyred by the Roman authorities either 187 or 295, depending on the source. At one time there were in excess of four hundred churches dedicated to St. Baudelius in France and northern Spain.
HILARY (HILARIUS, HILAIRE) of TOULOUSE, the third Bishop of Toulouse, from 358 to 360.
PLAUTILLA of ROME, the mother of Flavia Domitilla (12th May). According to an anonymous, but accepted, Life St. Plautilla was a Roman noblewoman who, as an adult, was baptised by the Apostle Peter (29th June). It is said St. Plautilla reposed circa 67.
THEODORE of PAVIA, the Bishop of Pavia from 743 until his repose in 778. St. Theodore was an unreservedly frank critic of Arianism, which earned the enmity of the Lombard Kings, who, amongst other hardships, repeatedly exiled St. Theodore.
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.
