Of these, Saint Isaacius is celebrated also on May 30. He became a monk at an early age and was a worker of every virtue; a zealot for the Orthodox Faith, he was also deemed worthy of the gift of prophecy. The Saint dwelt in a small hut near Constantinople. When Valens the Arian marched against the Goths, who were at the Danube River, this righteous one went out himself to meet the Emperor and, taking in hand the reins of the Emperor's horse, said to him with boldness that God had incited the barbarians to come against him, since he himself had incited many to speak against God in blasphemy, and had driven God's true worshippers out of the divine houses of prayer. Furthermore, he told him, if he ceased fighting against God by means of heresy and returned the good shepherds (that is, the Orthodox bishops) to the flock of Christ, he would easily gain the victory over his enemies. However, if he did not desist from these things, nor have God as his ally, at the very outset of the battle both he and his army would certainly be destroyed. "Learn from experience," he said, "that it is hard to kick against the pricks. Thou shalt not return, and this expedition will be destroyed." But the Emperor became angry and had the righteous one locked in prison that he might punish him and put him to death on his return after he conquered the barbarians. But he was utterly defeated and was burned alive in a certain village in the year 378 (Theodoret of Cyrrhus, Eccl. Hist., ch. 4: 31-32). When his surviving soldiers returned from the war, wishing to tempt the Saint, they came to him and said, "Prepare to make thy defense before the Emperor, who is coming to fulfil what he spoke against thee." But the Saint answered, "It has already been seven days that I smelled the stink of his bones, which were burned in the fire." Thus the righteous one was released from prison. All marveled because of his prophecy, and he became even more wondrous by means of the zeal he displayed in behalf of Orthodoxy in 381, when the Second Ecumenical Council was convoked. After this, a monastery was built in Constantinople for him, and he piously shepherded those struggling with him in asceticism. Having served as an example of the monastic life for them, he reposed in peace about the end of the fourth century, leaving Dalmatus as his successor.

As for Saint Dalmatus, he was at first a soldier in the second division of the soldiers known as the Scholarii. Later, however, he forsook all things and taking his son Faustus, went to the above-mentioned monastery of Saint Isaacius, where he donned the monastic habit. Through his virtue he became venerable in the sight of all. He was present at the Third Ecumenical Council that was convoked in Ephesus in 431, and there displayed his zeal for Orthodoxy against Nestorius. The Council elected him Archimandrite of the monasteries in Constantinopie. Having lived for more than eighty years, he reposed in the Lord.

The Seven Youths hid themselves in a certain cave near Ephesus in the year 250, to escape the persecution of Decius. By divine grace, a sleep came upon them and they slept for 184 years, until the reign of Saint Theodosius the Younger, when the doctrine of the resurrection was being assailed by heretics. They then awoke, that is, were resurrected, confirming in the sight of all the bodily resurrection; and again after a short time, by divine command, they reposed in the Lord in the year 434.

This Martyr was from Antioch, and had been a soldier from the time of the reign of Constantius Chlorus (the father of Saint Constantine the Great) to that of Julian the Apostate. He censured Julian's ungodliness and reminded him that he was the nephew of Saint Constantine the Great, the first Christian Emperor. He reminded him further, that from his tender youth he had been nourished on the milk of piety and instructed in the Faith of Christ, had been a fellow student of Basil the Great and Gregory the Theologian, had been a reader of the Church of Nicomedia, and that he had set all these things at nought and become a transgressor of the promises made in his divine Baptism, and had offered to the idols the adoration that is due to God alone. Reminding the Apostate of all these things and reproving him, he was beheaded in the year 361, having lived altogether 110 years, and been a soldier for more than sixty.

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(109):8). After this, it is said, Matthias preached the Gospel in Ethiopia, and completed his life there in martyrdom.
