After returning to Antioch, Cyprian was revered by the pagans as a prominent pagan priest, amazing people by his ability to cast spells, to summon pestilence and plagues, and to conjure up the dead. He brought many people to ruin, teaching them to serve demons and how to cast magic spells.
The holy virgin Justina lived in Antioch. After turning her own father and mother away from pagan error and leading them to the true faith in Christ, she dedicated herself to the Heavenly Bridegroom and spent her time in fasting and prayer. When the youth Aglaides proposed marriage to her, the saint refused, for she wished to remain a virgin. Agalides sought Cyprian’s help and asked for a magic spell to charm Justina into marriage. But no matter what Cyprian tried, he could accomplish nothing, since the saint overcame all the wiles of the devil through her prayers and fasting.
Cyrian sent demons to attack the holy virgin, trying to arouse fleshly passions in her, but she dispelled them by the power of the Sign of the Cross and by fervent prayer to the Lord.
Even though one of the demonic princes and Cyprian himself, assumed various guises by the power of sorcery, they were not able to sway Saint Justina, who was guarded by her firm faith in Christ. All the spells dissipated, and the demons fled at the mere mention of the saint’s name.
Cyprian, in a rage, sent down pestilence and plague upon Justina’s family and upon all the city, but this was thwarted by her prayer. Cyprian’s soul, corrupted by its domination over people and by his incantations, was shown in all the depth of his downfall, and also the abyss of nothingness of the evil that he served.
“If you take fright at even the mere shadow of the Cross and the Name of Christ makes you tremble,” said Cyprian to Satan, “then what will you do when Christ Himself stands before you?” The devil then flung himself upon the pagan priest who had begun to repudiate him, and attempted to beat and strangle him.
Saint Cyrian then first tested for himself the power of the Sign of the Cross and the Name of Christ, guarding himself from the fury of the enemy. Afterwards, with deep repentance he went to the local bishop Anthimus and threw all of his books into the flames. The very next day, he went into the church, and did not want to leave it, though he had not yet been baptized.
By his efforts to follow a righteous manner of life, Saint Cyprian discerned the great power of fervent faith in Christ, and made up for more than thirty years of service to Satan. Seven days after Baptism he was ordained reader, on the twelfth day, sub-deacon, on the thirtieth, deacon. After a year, he was ordained priest. In a short time Saint Cyprian was elevated to the rank of bishop.
The Hieromartyr Cyprian converted so many pagans to Christ that in his diocese there was no one left to offer sacrifice to idols, and the pagan temples fell into disuse. Saint Justina withdrew to a monastery and there was chosen Abbess.
During the persecution against Christians under the emperor Diocletian, Bishop Cyprian and Abbess Justina were arrested and brought to Nicomedia, where after fierce tortures they were beheaded with the sword. Saint Cyprian, fearful that the holy virgin’s courage might falter if she saw him put to death, asked for time to pray. Saint Justina joyfully inclined her neck and was beheaded first.
The soldier Theoctistus, seeing the guiltless sufferings of Saint Justina, fell at Cyprian’s feet and declared himself a Christian, and was beheaded.
