For more than one hundred years the Church of Christ was troubled by the persecution of the Iconoclasts of evil belief, beginning in the reign of Leo the Isaurian (717-741) and ending in the reign of Theophilus (829-842). After Theophilus's death, his widow the Empress Theodora (celebrated Feb. 11), together with the Patriarch Methodius (June 14), established Orthodoxy anew. This ever-memorable Queen venerated the icon of the Mother of God in the presence of the Patriarch Methodius and the other confessors and righteous men, and openly cried out these holy words: "If anyone does not offer relative worship to the holy icons, not adoring them as though they were gods, but venerating them out of love as images of the archetype, let him be anathema." Then with common prayer and fasting during the whole first week of the Forty-day Fast, she asked God's forgiveness for her husband. After this, on the first Sunday of the Fast, she and her son, Michael the Emperor, made a procession with all the clergy and people and restored the holy icons, and again adorned the Church of Christ with them. This is the holy deed that all we the Orthodox commemorate today, and we call this radiant and venerable day the Sunday of Orthodoxy, that is, the triumph of true doctrine over heresy.

These holy Martyrs, who came from various lands, were all soldiers under the same general. Taken into custody for their faith in Christ, and at first interrogated by cruel means, they were then stripped of their clothing and cast onto the frozen lake which is at Sebastia of Pontus, at a time when the harsh and freezing weather was at its worst. They endured the whole night naked in such circumstances, encouraging one another to be patient until the end. He that guarded them, named Aglaius, who was commanded to receive any of them that might deny Christ, had a vision in which he saw heavenly powers distributing crowns to all of the Martyrs, except one, who soon after abandoned the contest. Seeing this, Aglaius professed himself a Christian and joined the Martyrs on the lake, and the number of forty remained complete. In the morning, when they were almost dead from the cold, they were cast into fire, after which their remains were thrown into the river. Thus they finished the good course of martyrdom in 320, during the reign of Licinius.
