Theonestus

Holy Hieromartyr Theonestus was, according to tradition, bishop of Philippi in Macedonia, driven out by the Arians. He was sent with companions, among them Saint Alban of Mainz, to enlighten Germany. At Mainz they had to flee from invading Vandals, and on the way Theonestus was martyred at Altino in Italy, around 425. He is a saint of the undivided Church, known from the Western calendars. His story is confused and contradictory and may have been mixed up with that of a martyr of Vercelli of the same name, who is better attested historically.

He is commemorated on 30 October, the liturgical date in the Orthodox calendar (the same day number on the old and new calendars).
