This Saint, a wealthy nobleman of Constantinople, was filled with piety toward God. He had two sons, Arcadius and John, whom he sent to Beirut to study law. But they were shipwrecked during their voyage; barely saved, they forsook all things and departed for Palestine. Saint Xenophon and his wife Mary, ignorant of what had happened, went in search of their sons. On finding them in Jerusalem, dressed in the habit of monks, they also took up the monastic life. And thus, having completed their lives in holiness, they departed for the Lord about the beginning of the sixth century. Saint Xenophon and his sons reposed at Saint Sabbas Monastery, and Mary at the Monastery of Saint Theodosius.

Saint Ephraim was born in Nisibis of Mesopotamia some time about the year 306, and in his youth was the disciple of Saint James, Bishop of Nisibis, one of the 318 Fathers at the First Ecumenical Council. Ephraim lived in Nisibis, practicing a severe ascetical life and increasing in holiness, until 363, the year in which Julian the Apostate was slain in his war against the Persians, and his successor Jovian surrendered Nisibis to them. Ephraim then made his dwelling in Edessa, where he found many heresies to do battle with. He waged an especial war against Bardaisan; this gnostic had written many hymns propagating his errors, which by their sweet melodies became popular and enticed souls away from the truth. Saint Ephraim, having received from God a singular gift of eloquence, turned Bardaisan's own weapon against him, and wrote a multitude of hymns to be chanted by choirs of women, which set forth the true doctrines, refuted heretical error, and praised the contests of the Martyrs.

Of the multitude of sermons, commentaries, and hymns that Saint Ephraim wrote, many were translated into Greek in his own lifetime. Sozomen says that Ephraim "Surpassed the most approved writers of Greece," observing that the Greek writings, when translated into other tongues, lose most of their original beauty, but Ephraim's works "are no less admired when read in Greek than when read in Syriac" (Eccl. Hist., Book 111, 16). Saint Ephraim was ordained deacon, some say by Saint Basil the Great, whom Sozomen said "was a great admirer of Ephraim, and was astonished at his erudition." Saint Ephraim was the first to make the poetic expression of hymnody and song a vehicle of Orthodox theological teachings, constituting it an integral part of the Church's worship; he may rightly be called the first and greatest hymnographer of the Church, who set the pattern for these who followed him, especially Saint Romanos the Melodist. Because of this he is called the "Harp of the Holy Spirit." Jerome says that his writings were read in some churches after the reading of the Scriptures, and adds that once he read a Greek translation of one of Ephraim's works, "and recognized, even in translation, the incisive power of his lofty genius" (De vir. ill., ch. CXV).

Shortly before the end of his life, a famine broke out in Edessa, and Saint Ephraim left his cell to rebuke the rich for not sharing their goods with the poor. The rich answered that they knew no one to whom they could entrust their goods. Ephraim asked them, "What do you think of me?" When they confessed their reverence for him, he offered to distribute their alms, to which they agreed. He himself cared with his own hands for many of the sick from the famine, and so crowned his life with mercy and love for neighbor. Saint Ephraim reposed in peace, according to some in the year 373, according to others, 379.

The great luminary of the life of stillness, Saint Isaac, was born in the early seventh century in Eastern Arabia, the present-day Qatar on the Persian Gulf. He became a monk at a young age, and at some time left Arabia to dwell with monks in Persia. He was consecrated Bishop of Nineveh (and is therefore sometimes called "Saint Isaac of Nineveh"), but after five months received permission to return to solitude; he spent many years far south of Nineveh in the mountainous regions of Beit Huzaye, and lastly at the Monastery of Rabban Shabur. He wrote his renowned and God-inspired Ascetical Homilies toward the end of his long life of monastic struggle, about the end of the seventh century. The fame of his Homilies grew quickly, and about one hundred years after their composition they were translated from Syriac into Greek by two monks of the Monastery of Mar Sabbas in Palestine, from which they spread throughout the monasteries of the Roman Empire and became a guide to the hesychasts of all generations thereafter.

Saint Ignatius was a disciple of Saint John the Theologian, and a successor of the Apostles, and he became the second Bishop of Antioch, after Evodus. He wrote many epistles to the faithful, strengthening them in their confession, and preserving for us the teachings of the holy Apostles. Brought to Rome under Trajan, he was surrendered to lions to be eaten, and so finished the course of martyrdom about the year 107. The remnants of his bones were carefully gathered by the faithful and brought to Antioch. He is called God-bearer, as one who bare God within himself and was aflame in heart with love for Him. Therefore, in his Epistle to the Romans (ch. 4), imploring their love not to attempt to deliver him from his longed-for martyrdom, he said, "I am the wheat of God, and am ground by the teeth of the wild beasts, that I may be found to be the pure bread of God."

Saint John Chrysostom has a homily in honour of the translation of the Saint's relics (PG 50:587).

This common feast of these three teachers was instituted a little before the year 1100, during the reign of the Emperor Alexis I Comnenus, because of a dispute and strife that arose among the notable and virtuous men of that time. Some of them preferred Basil, while others preferred Gregory, and yet others preferred John Chrysostom, quarreling among themselves over which of the three was the greatest. Furthermore, each party, in order to distinguish itself from the others, assumed the name of its preferred Saint; hence, they called themselves Basilians, Gregorians, or Johannites. Desiring to bring an end to the contention, the three Saints appeared together to the saintly John Mavropous, a monk who had been ordained Bishop of Euchaita, a city of Asia Minor, they revealed to him that the glory they have at the throne of God is equal, and told him to compose a common service for the three of them, which he did with great skill and beauty. Saint John of Euchaita (celebrated Oct. 5) is also the composer of the Canon to the Guardian Angel, the Protector of a Man's Life. In his old age, he retired from his episcopal see and again took up the monastic life in a monastery in Constantinople. He reposed during the reign of the aforementioned Emperor Alexis Comnenus (1081-1118).

These Saints lived during the years of Diocletian. Saint Cyrus was from Alexandria, and Saint John was from Edessa of Mesopotamia. Because of the persecution of that time, Cyrus fled to the Gulf of Arabia, where there was a small community of monks. John, who was a soldier, heard of Cyrus' fame and came to join him. Henceforth, they passed their life working every virtue, and healing every illness and disease freely by the grace of Christ; hence their title of "Unmercenaries." They heard that a certain woman, named Athanasia, had been apprehended together with her three daughters, Theodora, Theoctiste, and Eudoxia, and taken to the tribunal for their confession of the Faith. Fearing lest the tender young maidens be terrified by the torments and renounce Christ, they went to strengthen them in their contest in martyrdom; therefore they too were seized. After Cyrus and John and those sacred women had been greatly tormented, all were beheaded in the year 292. Their tomb became a renowned shrine in Egypt, and a place of universal pilgrimage. It was found in the area of the modern day resort near Alexandria named Abu Kyr.

The Holy Martyr Trypho was from Lampsacus in Phrygia, and as a young man he tended geese. Being filled with the gifts of the Holy Spirit, he also healed sufferings and cast out demons. During the reign of the Emperor Decius, about the year 250, he was betrayed as a Christian and taken to Nicaea, where he was beaten, bound to horses and dragged over rough ground, then dragged naked over nails; his sides were burned with torches; finally he was sentenced to beheading, but gave up his holy soul in his torments before the stroke of the sword. Saint Trypho is one of the Holy Unmercenaries, and is also invoked for the protection of gardens from insects and pests.
