Our Lord had spoken to His disciples many times not only concerning His Passion, Cross, and Death, but also concerning the coming persecutions and afflictions that they themselves would endure. Since all these evils were near at hand, but the enjoyment of good things which they hoped to receive in their stead was yet to come, our Savior desired to give them full assurance, evidently and openly, concerning that glory which is prepared for those who endure to the end. Therefore, fulfilling that which He had promised shortly before, that "there be some standing here which shall not taste of death, till they see the Son of man coming in His Kingdom" (Matt. 16:28), He took His three foremost disciples and ascended Mount Tabor, where He was transfigured before them. His face shone like the sun, and His clothes became white as the light. Suddenly, together with this dread and marvelous effulgence of light, there appeared those pinnacles of the Prophets, Moses and Elias, who spoke with the Lord Jesus concerning His saving Passion which was about to take place. Standing before Him as reverent servants, they showed that He is the Lord of both the living and the dead, for Moses came forth from Hades, having died many centuries before, and Elias, as it were from heaven, whither he had been taken up while yet alive. After a little while a radiant cloud overshadowed them and out of the cloud they heard that same voice which had been heard at the Jordan at the Baptism of Christ, testifying to the Divinity of Jesus and saying: "This is My beloved Son, in Whom I am well-pleased; hear ye Him" (Matt. 17: 5).

Such are the marvels, truly worthy of God, celebrated in this present feast, which is an image and prefiguring of the future state of the righteous, whose splendor the Lord spoke of, saying: "Then shall the righteous shine forth as the sun" (Matt. 13:43). It is because of this that the Kontakion of this Feast is said daily (when there is not a great feast) in the Service of the Typica in perpetual commemoration of the glory that will be the lot of the Saints. According to tradition, the Lord's Transfiguration came to pass forty days before His Crucifixion; this is why the Transfiguration is celebrated forty days before the Exaltation of the Cross.

This Martyr, who lived during the reign of Saint Constantine the Great, was a Persian by race and an idolater by religion. He was catechized by a certain Christian named Abarus. He went to Nisibis, a city of Mesopotamia, where he was baptized and donned the monastic habit in a certain monastery. He afterwards ascended a mountain and there endured in extreme ascetical struggles, working miracles for those that came to him, and converting many unbelievers. Julian the Apostate learned of these things as he was marching against the Persians in 363, and at his command the Saint and his two disciples were stoned to death, as they were chanting the Sixth Hour.

After Judas by transgression fell from his apostleship (Acts 1: 25), and hanging himself out of despair ended his life with a wretched and shameful death (Matt. 27: 5), then, that the number of the Twelve not be lacking, all the disciples gathered in one place after the Ascension of the Savior (the number of men and women being 120), and they chose two men from among them, Joseph, called Barsabas, who was also surnamed Justus, and Matthias, and they set them in the midst. Then they prayed to God and cast lots, "and the lot fell upon Matthias, and he was numbered with the eleven Apostles" (Acts 1: 15-26). And thus, having taken the place of Judas, Matthias fulfilled the work of apostleship and the prophecy concerning Judas, which the Holy Spirit foretold by the mouth of David: "And his bishopric let another take" (Ps. 108:7). After this, it is said, Matthias preached the Gospel in Ethiopia, and completed his life there in martyrdom.

This Saint, who was born in Spain, was the Archdeacon of the Church of Rome, caring for the sacred vessels of the Church and distributing money to the needy. About the year 257, a harsh persecution was raised up against the Christians by Valerian. Pope Sixtus, who was from Athens, was commanded to worship the idols, and refused; before his martyrdom by beheading, he committed to Laurence all the sacred vessels of the Church. When Laurence was arrested and brought before the Prefect, he was questioned concerning the treasures of the Church; he asked for three days' time to prepare them. He then proceeded to gather all the poor and needy, and presented them to the Prefect and said, "Behold the treasures of the Church." The Prefect became enraged at this and gave command that Laurence be racked, then scourged with scorpions (a whip furnished with sharp iron points - compare II Chron. 10:11), then stretched out on a red-hot iron grill. But the courageous athlete of Christ endured without groaning. After he had been burned on one side, he said, "My body is done on one side; turn me over on the other." And when this had taken place, the Martyr said to the tyrants, "My flesh is now well done, you may taste of it." And when he had said this, and had prayed for his slayers in imitation of Christ, he gave up his spirit on August 10, 258.
