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. These are their names: Acacius, Aetius, Aglaius, Alexander, Angus, Athanasius, Candidus, Chudion, Claudius, Cyril, Cyrion, Dometian, Domnus, Ecdicius, Elias, Eunoicus, Eutyches, Eutychius, Flavius, Gaius, Gorgonius, Helianus, Heraclius, Hesychius, John, Lysimachus, Meliton, Nicholas, Philoctemon, Priscus, Sacerdon, Severian, Sisinius, Smaragdus, Theodulus, Theophilus, Valens, Valerius, Vivianus, and Xanthias.

This Saint was born in Damascus. As a young man he became a monk at the Monastery of Saint Theodosius the Cenobiarch in Palestine, where he met John Moschus and became his close friend. Having a common desire to search out ascetics from whom they could receive further spiritual instruction, they journeyed together through Palestine, Syria, Asia Minor, and Egypt, where they met the Patriarch of Alexandria, Saint John the Almsgiver, with whom they remained until 614, when Persians captured Jerusalem (see also Saint Anastasius the Persian, Jan. 22). Saint Sophronius and John Moschus departed Alexandria for Rome, where they remained until 619, the year of John Moschus' death. Saint Sophronius returned to the Monastery of Saint Theodosius the Cenobiarch, and there buried the body of his friend. He laboured much in defence of the Holy Fourth Council of Chalcedon, and traveled to Constantinople to remonstrate with Patriarch Sergius and the Emperor Heraclius for changing the Orthodox Faith with their Monothelite teachings. After the death of Patriarch Modestus in December of 634, Sophronius was elected Patriarch of Jerusalem. Although no longer in the hands of the Persians, the Holy Land was now besieged by the armies of the newly-appeared religion of Mohammed, which had already taken Bethlehem; in the Saint's sermon for the Nativity of our Lord in 634, he laments that he could not celebrate the feast in Bethlehem. In 637, for the sins of the people, to the uttermost grief of Saint Sophronius, the Caliph Omar captured Jerusalem. Having tended the flock of his Master for three years and three months, Saint Sophronius departed in peace unto Him Whom he loved on March 11, 638.

Saint Sophronius has left to the Church many writings, including the life of Saint Mary of Egypt. The hymn "O Joyous Light," which is wrongly ascribed to him, is more ancient than Saint Basil the Great, as the Saint himself confirms in his work "On the Holy Spirit" (ch. 29). However, it seems that this hymn, which was chanted at the lighting of the lamps and was formerly called "The Triadic Hymn," was later supplemented somewhat by Saint Sophronius, bringing it into the form in which we now have it. Hence, some have ascribed it to him.

Saint Gregory was born in Rome to noble and wealthy parents about the year 540. While the Saint was still young, his father died. However, his mother, Sylvia, saw to it that her child received a good education in both secular and spiritual learning. He became Prefect of Rome and sought to please God even while in the world; later, he took up the monastic life; afterwards he was appointed Archdeacon of Rome, then, in 579, apocrisiarius (representative or Papal legate) to Constantinople, where he lived for nearly seven years. He returned to Rome in 585 and was elected Pope in 590. He is renowned especially for his writings and great almsgiving, and also because, on his initiative, missionary work began among the Anglo-Saxon people. It is also from him that Gregorian Chant takes its name; the chanting he had heard at Constantinople had deeply impressed him, and he imported many elements of it into the ecclesiastical chant of Rome. He served as Bishop of that city from 590 to 604.

This Saint, whose name means "blessed," was born in 480 in Nursia, a small town about seventy miles northeast of Rome. He struggled in asceticism from his youth in deserted regions, where his example drew many who desired to emulate him. Hence, he ascended Mount Cassino in Campania and built a monastery there. The Rule that he gave his monks, which was inspired by the writings of Saint John Cassian, Saint Basil the Great, and other Fathers, became a pattern for monasticism in the West; because of this, he is often called the first teacher of monks in the West. He reposed in 547.
