The Holy 20,000 Martyrs of Nicomedia: At the beginning of the fourth century the emperor Maximian (284-305) gave orders to destroy Christian churches, to burn service books, and to deprive all Christians of rights and privileges of citizenship. At this time the bishop of the city of Nicomedia was St Cyril, who by his preaching and life contributed to the spread of Christianity, so that many members of the emperor’s court were also secret Christians.
St Glycerius was a priest who perished in the church with the 20,000 Martyrs of Nicomedia.
The emperor Maximian went to the church with soldiers and told the Christians they could escape punishment if they renounced Christ. Otherwise, he promised to burn the church and those in it. The priest Glycerius told him that Christians would never renounce their faith, even under the threat of torture. Hiding his anger, the emperor exited the church, and a short time later commanded that Glycerius be arrested and put on trial.
The executioners tortured the martyr, who did not cease to pray and to call on the Name of the Lord. Unable to force St Glycerius stop confessing Christ, Maximian ordered him to be burned to death.
