Saint Gregory was born in Neocaesarea of Pontus to parents who were not Christians. He studied in Athens, in Alexandria, in Beirut, and finally for five years in Caesarea of Palestine under Origen, by whom he was also instructed in the Faith of Christ. Then, in the year 240, he became bishop of his own city, wherein he found only seventeen Christians. By the time the Saint reposed about the year 265, there were only seventeen unbelievers left there. Virtually the whole duration of his episcopacy was a time of continual, marvellous wonders worked by him. Because of this, he received the surname "Wonderworker"; even the enemies of the truth called him a second Moses (see Saint Basil the Great's On the Holy Spirit, ch. 29).

Saint Plato contested in martyrdom in 266, when Agrippinus was proconsul. He was from the city of Ancyra in the province of Galatia.

The Divine Scriptures do not tell us with any certainty when the Prophet Obadiah lived nor what was his homeland. Thus, some say that he is that Obadiah who was Ahab's steward, who, because of Jezebel's wrath, hid one hundred prophets in a cave and fed them with bread and water (III Kings 18:4), and that he later became a disciple of Elias the Prophet about 903 B.C. But others surmise from the words of the same prophetical book that he is somewhat later than Joel (celebrated on Oct. 19). He is also called Obdiu, or Abdiu, or Obadiah; his name means "servant of God." His book of prophecy, which consists of only one chapter, is ranked fourth among the minor Prophets.

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 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.
