Saint Proclus lived during the reign of Saint Theodosius the Younger. A disciple and scribe of Saint John Chrysostom, he was ordained Bishop of Cyzicus about the year 426, but because the people there unlawfully elected another bishop before his arrival, he remained in Constantinople. In 429, Nestorius, who had been Archbishop of Constantinople for about a year, and had already begun his blasphemous teaching that it is wrong to call the holy Virgin "Theotokos," invited Bishop Proclus to give a sermon on one of the feasts of our Lady, which he did, openly defending in Nestorius' presence the name "Theotokos," that is, "Mother of God." Saint Proclus was elevated to the throne of Archbishop of Constantinople in 434. It was he who persuaded Emperor Theodosius the Younger and his holy sister Pulcheria to have the most sacred relics of his godly teacher Saint John Chrysostom brought back from Comana, and triumphantly received them upon their return to the imperial city (see Jan. 27 and Nov. 13). He reposed in peace in 447.

Saint Gregory who was from Irenopolis of the Decapolis of Asia Minor, was the son of Sergius and Mary. He became a monk as a young man, and after struggling for many years in virtue and prayer under obedience to a wise spiritual father, he was informed by revelation that it was the will of God for him to live, like the Patriarch Abraham, with no certain dwelling, moving from place to place. His journeyings took him to Ephesus, Constantinople, Corinth, Rome, Sicily, Thessalonica, and again to Constantinople, where, after many labours in defence of Orthodoxy against Iconoclasm, he reposed in peace in the first half of the ninth century. He had two disciples, one of whom was Saint Joseph the Hymnographer (see Apr. 3), who wrote the Menaion service for Saint Gregory, his father in Christ.

According to the tradition of the Church, the Theotokos was brought to the Temple at three years of age, where she was consecrated to God and spent her days until she was fourteen or fifteen years old; and then, as a mature maiden, by the common counsel of the priests (since her parents had reposed some three years before), she was betrothed to Joseph.

Philemon, who was from Colossae, a city of Phrygia, was a man both wealthy and noble; Apphia was his wife. Archippus became Bishop of the Church in Colossae. All three were disciples of the Apostle Paul. Onesimus, who was formerly an unbeliever and slave of Philemon, stole certain of his vessels and fled to Rome. However, on finding him there, the Apostle Paul guided him onto the path of virtue and the knowledge of the truth, and sent him back to his master Philemon, to whom he wrote an epistle (this is one of the fourteen epistles of Saint Paul). In this epistle, Paul commended Onesimus to his master and reconciled the two. Onesimus was later made a bishop; in Greece he is honoured as the patron Saint of the imprisoned. All these Saints received their end by martyrdom, when they were stoned to death by the idolaters. Saint Onesimus is also commemorated on February 15.

Saint Cecilia was of an illustrious Roman family. On being betrothed to Valerian, she drew him to the Faith of Christ, and he in turn drew his own brother Tiburtius to the same. They contested in martyrdom during the reign of Diocletian, in the year 288.

Saint Amphilochius, who was born in Cappadocia, shone forth in asceticism and divine knowledge even from his youth. He was consecrated Bishop of Iconium in 341, he struggled courageously against the blasphemies of Eunomius, Macedonius the enemy of the Holy Spirit, and the followers of Arius. He was present at the Second Ecumenical Council of the 150 Fathers, which took place in Constantinople, convoked during the reign of Theodosius the Great in the year 381. In 383 Amphilochius wished to persuade the Emperor Theodosius to forbid the Arians from gathering in Constantinople and to commit the churches to the Orthodox, but the Emperor was reluctant to do such a thing. The next time that Amphilochius entered the palace, he addressed Theodosius with proper honour, but slighted his young son Arcadius in his presence. Theodosius was indignant, and said the dishonour shown to his son was equally an insult to himself. To this Saint Amphilochius answered that as he would not suffer an insult to his son, so he ought to believe that God is wroth with those who blaspheme His Only-begotten. Saint Theodosius understood and admired Amphilochius' ingenious device, and he issued the desired edict in September of the same year. Saint Amphilochius, having reached deep old age, reposed in peace about the year 395. Saint Basil the Great wrote many letters to Saint Amphilochius, his friend and Fellow champion of the Faith, and at his request wrote his treatise On the Holy Spirit, which besides demonstrating the divinity of the Holy Spirit and His equality with the Father and the Son, defends the Church's unwritten ancient traditions, such as making the sign of the Cross, turning towards the East in prayer, no kneeling on Sunday, and so forth.

Saint Gregory, the son of pious parents named Chariton and Theodora, was born in Agrigentum, a city of Sicily, and was great in virtue from his childhood. He was baptized, brought up, and tonsured reader by Bishop Potamion during the reign of Justinian II, in the seventh century. At the age of eighteen he made a pilgrimage to Jerusalem, where he was ordained deacon by Macarius, Bishop of Jerusalem. He traveled to Constantinople, and then to Rome where he was consecrated Bishop of his native Agrigentum. As Bishop of Agrigentum he worked many miracles and shone brilliantly in virtue, but also suffered many great temptation; from the priests Sabine and Crescentius, who so envied him that they slandered him to the Pope as a fornicator and had him cast into prison for two and a half years. In the end, however, he vindicated himself by casting the demon out of the woman who had falsely accused him of committing sin with her. Saint Gregory reposed in peace in deep old age.

Saint Clement was instructed in the Faith of Christ by the Apostle Peter. He became Bishop of Rome in the year 91, the third after the death of the Apostles. He died as a martyr about the year 100 during the reign of Trajan.

Saint Peter illustriously occupied the throne of Alexandria for twelve years, and, as Eusebius says, "was a divine example of a bishop on account of the excellence of his life and his study of the sacred Scriptures" (see Eusebius, Eccl. Hist., Book VII, 3 2; Book VIII 11, 13; and Book IX, 6). He excommunicated Arius for his sympathy with the Meletian schism. When Arius learned that Saint Peter had been imprisoned, he sent many priests and deacons to him, asking that he receive him back into the communion of the Church before his martyrdom. When the ambassadors of Arius, who had not, like Saint Peter, perceived the ruin he would engender, were astonished at the vehemence with which Saint Peter refused to receive Arius again, he revealed to them a dread vision he had seen, in which the Master Christ had appeared to him as a child wearing a garment torn from head to foot. When Saint Peter asked the Lord who rent His garment, the Lord answered that it was Arius, and that he must not be received back into communion. The holy hieromartyr Peter was beheaded during the reign of Maximinus in the year 312; he is called the "Seal of the Martyrs," because he was the last Bishop of Alexandria to suffer martyrdom under the pagan Emperors. His successors to the throne of Alexandria, Saints Alexander and Athanasius the Great, brought to final victory the battle against Arius' heresy which Saint Peter had begun.

Saint Catherine, who was from Alexandria, was the daughter of Constas (or Cestus). She was an exceedingly beautiful maiden, most chaste, and illustrious in wealth, lineage, and learning. By her steadfast understanding, she utterly vanquished the passionate and unbridled soul of Maximinus, the tyrant of Alexandria; and by her eloquence, she stopped the mouths of the so-called philosophers who had been gathered to dispute with her. She was crowned with the crown of martyrdom in the year 305. Her holy relics were taken by Angels to the holy mountain of Sinai, where they were discovered many years later; the famous monastery of Saint Catherine was originally dedicated to the Holy Transfiguration of the Lord and the Burning Bush, but later was dedicated to Saint Catherine. According to the ancient usage, Saints Catherine and Mercurius were celebrated on the 24th of this month, whereas the holy Hieromartyrs Clement of Rome and Peter of Alexandria were celebrated on the 25th. The dates of the feasts of these Saints were interchanged at the request of the Church and Monastery of Mount Sinai, so that the festival of Saint Catherine, their patron, might be celebrated more festively together with the Apodosis of the Feast of the Entry of the Theotokos. The Slavic Churches, however, commemorate these Saints on their original dates.

Saint Mercurius came from Cappadocia, and was the son of Gordian, a Scythian. A young man, and a soldier of high rank, he refused to offer sacrifice to the idols, and after torments was beheaded during the reign of Valerian (253-260).

Saint Alypius was from Adrianople of Bithynia; having lived upon a pillar for fifty-three years, he reposed about the year 607, at the age of one hundred.

Saint Nicon, the son of a certain noble, was from Armenia. Forsaking his parents and homeland, he passed throughout the parts of the East, crying to all men, "Repent ye," because of which he received this name. Finally, he came to Lacedaemonia of the Peloponnesus, where he built a church in honour of Christ our Saviour. After having dwelt there many years in solitude, and having converted many from paganism, he departed to the Lord about the end of the ninth century.

St. Stylianos was from Paphlagonia living in the latter 6th century and early 7th century. He loved the Lord Jesus Christ with his whole heart and lived in strict asceticism. When he fell asleep in the Lord, his face shone like the sun and an angel appeared to take his soul to Glory. His prayers have worked many miracles, both during his earthly life and since. He is of special help to children who are ill and to childless couples. He is known as a protector of orphans.
