Julian the Apostate, knowing that the Christians purify themselves by fasting most of all during the first week of the Fast -- which is why we call it Clean Week -- planned to defile them especially at that time. Therefore he secretly commanded that during those days the markets be filled with foods that had been defiled with the blood of animals offered in sacrifice to idols. But by divine command the Martyr Theodore (see Feb. 17) appeared during sleep to Eudoxius, then Archbishop of Constantinople. The Saint revealed to him the tyrant's plan, then told him to call the faithful together immediately on Monday morning and prevent them from purchasing those foods, but rather to make kollyva to supply their needs. The bishop asked what kollyva might be, and the Saint answered, "Kollyva is what we call boiled wheat in Euchaita." Thus, the purpose of the Apostate was brought to nought, and the pious people who were preserved undefiled for the whole of Clean Week, rendered thanks to the Martyr on this Saturday, and celebrated his commemoration with kollyva. These things took place in 362. Wherefore, the Church keeps this commemoration each year to the glory of God and the honour of the Martyr.

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.
