GAIUS of MILAN, (First Century), very little is known with any certainty about St. Gaius. He is thought to have been a spiritual child of the Apostle Barnabas, and was the third Bishop of Milan (north-west Italy). He served that See for twenty-four years, and is believed to have baptised St. Vitalis of Milan (28th April) and SS. Gervase and Protase (19th June).

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.
