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.

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.

When the most pure Mother and Ever-Virgin Mary's forty days of purification had been fulfilled, she took her first-born Son to Jerusalem on this, the fortieth day after His birth, that she might present Him in the temple according to the Law of Moses, which teaches that every first-born male child be dedicated to God, and also that she might offer the sacrifice of a pair of turtle-doves or two young pigeons, as required by the Law (Luke 2:22-24; Exod. 13:2; Lev. 12:6-8). On this same day, a just and devout man, the greatly aged Symeon, was also present in the temple, being guided by the Holy Spirit. For a long time, this man had been awaiting the salvation of God, and he had been informed by divine revelation that he would not die until he beheld the Lord's Christ. Thus, when he beheld Him at that time and took Him up into his aged arms, he gave glory to God, singing: "Now lettest Thou Thy servant depart in peace, O Master. . ." And he confessed that he would close his eyes joyfully, since he had seen the Light of revelation for the nations and the Glory of Israel (Luke 2:25-32). From ancient times, the Holy Church has retained this tradition of the churching of the mother and new-born child on the fortieth day and of the reading of prayers of purification.

The Apodosis of the Feast of the Meeting in the Temple is usually on the 9th of February. This, however, may vary if the Feast falls within the period of the Triodion. Should this occur, the Typicon should be consulted for specific information concerning the Apodosis of the Feast.
