Nazarius, Gervasius, Protasius, & Celsus of Milan
The holy Martyrs all contested for piety's sake in Milan; after the passage of much time their holy relics were discovered and given honourable burial by Saint Ambrose.
Apolytikion of Martyrs Nazarius, Gervasius, Protasius, & Celsus in the Fourth Tone
Thy Martyrs, O Lord, in their courageous contest for Thee received as the prize the crowns of incorruption and life from Thee, our immortal God. For since they possessed Thy strength, they cast down the tyrants and wholly destroyed the demons' strengthless presumption. O Christ God, by their prayers, save our souls, since Thou art merciful.
Kontakion of Martyrs Nazarius, Gervasius, Protasius, & Celsus in the Second Tone
In shedding the light of miracles like shining lamps, O Martyrs of God, ye make the whole creation bright, at all times dispelling the deepest night of sickness and maladies and without cease pleading with Christ, the only God, that He grant His mercy to us.
