Theodulus of Thessalonica
lector and martyr at Thessalonica
Feast: 4 April (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
At Thessalonica, in Macedonia, now in Greece, the holy martyrs Agathopodes, deacon, and Theodulus, lector, who, under the emperor Maximian, by order of the governor Faustinus, for having confessed the Christian faith were thrown into the sea with a stone tied to their necks.
At Milan, the burial of Saint Ambrose, bishop, who on Holy Saturday went to meet Christ the conqueror of death. His memorial is kept on 7 December, the day of his ordination.
At Constantinople, Saint Plato, abbot, who fought long with undaunted spirit against the enemies of the sacred images and together with his nephew Theodosius set the famous monastery of Studios in order again.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The Roman Martyrology remembers him on 4 April as a lector of Thessalonica who was drowned with a stone tied to his neck for confessing the Christian faith under the emperor Maximian.
