The heresiarch Arius was a Libyan by race and a protopresbyter of the Church of Alexandria. In 315, he began to blaspheme against the Son and Word of God, saying that He is not true God, consubstantial with the Father, but is rather a work and creation, alien to the essence and glory of the Father, and that there was a time when He was not. This frightful blasphemy shook the faithful of Alexandria. Alexander, his Archbishop, after trying in vain to correct him through admonitions, cut him off from communion and finally in a local council deposed him in the year 321. Yet neither did the blasphemer wish to be corrected, nor did he cease sowing the deadly tares of his heretical teachings; but writing to the bishops of other cities, Arius and his followers requested that his doctrine be examined, and if it were unsound, that the correct teaching be declared to him. By this means, his heresy became universally known and won many supporters, so that the whole Church was soon in an uproar.

Therefore, moved by divine zeal, the first Christian Sovereign, Saint Constantine the Great, the equal to the Apostles, summoned the renowned First Ecumenical Council in Nicaea, a city of Bithynia. It was there that the shepherds and teachers of the Church of Christ gathered from all regions in the year 325. All of them, with one mouth and one voice, declared that the Son and Word of God is one in essence with the Father, true God of true God, and they composed the holy Symbol of Faith up to the seventh article (since the remainder, beginning with "And in the Holy Spirit," was completed by the Second Ecumenical Council). Thus they anathematized the impious Arius of evil belief and those of like mind with him, and cut them off as rotten members from the whole body of the faithful.

Therefore, recognizing the divine Fathers as heralds of the Faith after the divine Apostles, the Church of Christ has appointed this present Sunday for their annual commemoration, in thanksgiving and unto the glory of God, unto their praise and honour, and unto the strengthening of the true Faith.

Saint Nicephorus was born in Constantinople about the year 758, of pious parents; his father Theodore endured exile and tribulation for the holy icons during the reign of Constantine Copronymus (741-775). Nicephorus served in the imperial palace as a secretary. Later, he took up the monastic life, and struggled in asceticism not far from the imperial city; he also founded monasteries on the eastern shore of the Bosphorus, among them one dedicated to the Great Martyr Theodore.

After the repose of the holy Patriarch Tarasius, he was ordained Patriarch, on April 12, 806, and in this high office led the Orthodox resistance to the Iconoclasts' war on piety, which was stirred up by Leo the Armenian. Because Nicephorus championed the veneration of the icons, Leo drove Nicephorus from his throne on March 13, 815, exiling him from one place to another, and lastly to the Monastery of Saint Theodore which Nicephorus himself had founded. It was here that, after glorifying God for nine years as Patriarch, and then for thirteen years as an exile, tormented and afflicted, he gave up his blameless soul in 828 at about the age of seventy. See also March 8.

Formerly a priest of the idols near Nicomedia, the Saint came to the Christian Faith in his old age; this was during the reign of Aurelian (270-275). Lucillian was brought before Silvan the Count; when he refused to return to the service of the idols, his jaw was broken, he was beaten with rods, and hanged upside down, then imprisoned with four Christian children, Claudius, Hypatius, Paul, and Dionysius. All of them were brought out again before Silvan, and remaining constant in their faith, were cast into a raging furnace. Preserved unharmed, they were sent to Byzantium, where the children were beheaded, and Lucillian was crucified. The virgin Paula, a Christian, buried their holy relics. For this, she was taken before the Count, and refusing to sacrifice to the idols, was stripped naked and mercilessly thrashed; after other torments, she was beheaded, in 270. There was a church in their honor in Constantinople.

Saint Metrophanes was born of pagan parents, but believed in Christ at a young age, and came to Byzantium. He lived at the end of the persecution of the Roman Emperors, and became the Bishop of Byzantium from about 315 to 325, during which time Saint Constantine the Great made it the capital of the Roman Empire, calling it New Rome. Saint Metrophanes sent his delegate, the priest Alexander, to the First Ecumenical Council in 325, since he could not attend because of old age. He reposed the same year and was buried by Saint James of Nisibis (celebrated Jan. 13), one of the Fathers present at the First Ecumenical Council. The Canons to the Trinity of the Octoechos are not the work of this Metrophanes but another, who was Bishop of Smyrna about the middle of the ninth century, during the life of Saint Photius the Great.

Saint Dorotheus became Bishop of Tyre in Phoenicia about the end of the third century. During the persecution of Diocletian and Maximian, about the year 303, he fled to Odyssopolis in Thrace to preserve his life, and after the death of the tyrants he returned to Tyre. He lived until the reign of Julian the Apostate (361-363), from whose persecution he again fled to Odyssopolis (or, according to Theophylact of Bulgaria, Edessa), but was found by Julian's men and slain in great torments, at the age of 107, in 361. He was very learned, and has left behind writings in both Latin and Greek relating the lives of the holy Prophets, Apostles, and other Saints.

Saint Hilarion, the fervent zealot for the veneration of the holy icons, was born in 775 and had Cappadocia as his homeland. About 806-811 he became Abbot of the Monastery of Dalmatus (see May 30), but was exiled by the Emperor Leo the Armenian, and later again by Theophilus; he was set free by the pious Empress Theodora, and again became Abbot of the Monastery of Dalmatus from 843 to 845, until the time of his repose.

This Martyr contested in Ancyra during the reign of Diocletian (284-305), when Theotecnus was Proconsul. After the martyrdom of the virgin Tecusa and her seven companions (the virgins Alexandria, Claudia, Phaeina, Euphrasia, Matrona, Julia, and Theodota; they are celebrated on May 18), Saint Theodotus recovered their holy relics and buried them. For this, he was seized by Theotecnus, tormented, and beheaded.
