Saint Callistratus was a native of Carthage. An ancestor of Saint Callistratus, Neoscorus, has served under the emperor Tiberius in Palestine, under the command of the procurator of Judea Pontius Pilate, and was a witness to the suffering on the Cross and glorious Resurrection of our Lord Jesus Christ. The father of the saint was a Christian, and he raised his son in faith and piety. Also like his father, Saint Callistratus became a soldier and excelled among his pagan military comrades by good conduct and gentle disposition. During the nights when everyone slept, he usually stayed up at prayer.
One time a soldier sleeping nearby him heard Saint Callistratus invoking the Name of the Lord Jesus Christ, and he reported this to the military commander, who in turn summoned Callistratus, interrogated him, and wanted to make him offer sacrifice to idols. To this the saint answered firmly with a resolute refusal. Then the military commander gave orders to beat the saint and then, covered with wounds, to drag him over sharp stones. The beating and the torments did not sway the firm will and brave endurance of the sufferer. The torturer gave orders to sew up the saint in a leather sack and drown him in the sea. By Divine Providence however the sack came upon a sharp rock tearing it, and Saint Callistratus, supported by dolphins, came to dry land unharmed. Viewing such a miracle, forty-nine soldiers came to believe in Christ. Then the military commander threw Saint Callistratus together with the believing soldiers into prison. Before this, all of them were subjected to innumerable floggings.
In confinement, Saint Callistatus continued to preach the Word of God to the soldiers and he bolstered their spirits for the martyr’s act. Summoned again to the military commander, the sufferers firmly confessed their faith in Christ, after which they bound them hand and foot and threw them into a water-dam. But there their bonds broke, and with bright faces the holy martyrs stood in the water, rejoicing in their Baptism, which coincided with the act of martyrdom. Over them were beautiful bright crowns, and all heard a voice: “Be brave, Callistratus, with thy company, and come rest in the eternal habitations.” At the same time with this, the earth shuddered and an idol standing not far off fell down and smashed. Beholding this happening, another 135 soldiers also believed in the Lord Jesus Christ. The military commander, fearing a mutiny in the army, did not set about to judge them, but again imprisoned Saint Callistratus with the others, where they fervently prayed and gave thanks to the Creator, for having given them power to endure such sufferings. At night by order of the military commander they chopped the martyrs to pieces with swords. Their holy remains were buried by the remaining-alive 135 soldiers, and afterwards on the spot of their sufferings, as Saint Callistatus had foretold, a church was built.
