Christopher, Theonas and Antonius were young officers serving under Emperor Diocletian. When St. George the Great Martyr was being tortured, they witnessed his sufferings as well as the miracles which occurred at that time. Seeing all of this, they came before the emperor, laid down their arms, removed their military belts and bravely confessed the Name of the Lord Jesus. For that, they were subjected to great torture and finally were tossed into the fire, where their bodies were consumed while their souls went to God into eternal joy. They honorably suffered in Nicomedia in the year 303 A.D.
