Eusignius the Martyr of Antioch
This Martyr was from Antioch, and had been a soldier from the time of the reign of Constantius Chlorus (the father of Saint Constantine the Great) to that of Julian the Apostate. He censured Julian's ungodliness and reminded him that he was the nephew of Saint Constantine the Great, the first Christian Emperor. He reminded him further, that from his tender youth he had been nourished on the milk of piety and instructed in the Faith of Christ, had been a fellow student of Basil the Great and Gregory the Theologian, had been a reader of the Church of Nicomedia, and that he had set all these things at nought and become a transgressor of the promises made in his divine Baptism, and had offered to the idols the adoration that is due to God alone. Reminding the Apostate of all these things and reproving him, he was beheaded in the year 361, having lived altogether 110 years, and been a soldier for more than sixty.
Apolytikion of Martyr Eusignius in the Fourth Tone
Thy Martyr, O Lord, in his courageous contest for Thee received the prize of the crowns of incorruption and life from Thee, our immortal God. For since he possessed Thy strength, he cast down the tyrants and wholly destroyed the demons' strengthless presumption. O Christ God, by his prayers, save our souls, since Thou art merciful.
Kontakion of Martyr Eusignius in the Plagal of the Fourth Tone
As to a man of godly mind and Martyr for true piety, today the Church doth give honour and glory to the supremely wise Eusignius; and his all-hallowed contests doth she praise, as she ever crieth out: By his prayers, preserve Thy lowly servants, O Thou Who art greatly merciful.
