The Holy Martyrs Christopher, Theonas, and Anthony were officers in the army of the emperor Diocletian (284-305). They were present at the sufferings of the Holy Great Martyr George (April 23), they saw the miracles accomplished by the power of God, and they witnessed St George's faith and unshakable courage.
The soldiers came to believe in the Savior, threw down their golden military belts, and declared themselves Christians in front of the emperor. They were immediately thrown into prison. The next day the emperor urged the former soldiers to renounce Christ, but they firmly confessed their faith and glorified the Savior as the true God.
The emperor ordered that the martyrs be beaten with iron rods, and their bodies to be raked with hooks. The holy martyrs endured all the torments and remained unyielding. Then Diocletian gave orders to burn them. The martyric death of Sts Christopher, Theonas, and Anthony occurred in the year 303. SOURCE:
