This great Father and Teacher of the Church was born in 329 in Arianzus, a village of the second district of Cappadocia, not far from Nazianzus. His father, who later became Bishop of Nazianzus, was named Gregory (commemorated Jan. 1), and his mother was named Nonna (Aug. 5); both are among the Saints, and so are his brother Caesarius (Mar. 9) and his sister Gorgona (Feb. 23). At first he studied in Caesarea of Palestine, then in Alexandria, and finally in Athens. As he was sailing from Alexandria to Athens, a violent sea storm put in peril not only his life but also his salvation, since he had not yet been baptized. With tears and fervour he besought God to spare him, vowing to dedicate his whole self to Him, and the tempest gave way to calm. At Athens Saint Gregory was later joined by Saint Basil the Great, whom he already knew; but now their acquaintanceship grew into a lifelong brotherly love. Another fellow student of theirs in Athens was the young Prince Julian, who later as Emperor was called the Apostate because he denied Christ and did all in his power to restore paganism. Even in Athens, before Julian had thrown off the mask of piety; Saint Gregory saw what an unsettled mind he had, and said, "What an evil the Roman State is nourishing" (Orat. V, 24, PG 35:693).

After their studies at Athens, Gregory became Basil's fellow ascetic, living the monastic life together with him for a time in the hermitages of Pontus. His father ordained him presbyter of the Church of Nazianzus, and Saint Basil consecrated him Bishop of Sasima (or Zansima), which was in the archdiocese of Caesarea. This consecration was a source of great sorrow to Gregory, and a cause of misunderstanding between him and Basil; but his love for Basil remained unchanged, as can be plainly seen from his Funeral Oration on Saint Basil (Orat. XLIII).

About the Year 379, Saint Gregory came to the assistance of the Church of Constantinople, which had already been troubled for forty years by the Arians; by his supremely wise words and many labours he freed it from the corruption of heresy, and was elected Archbishop of that city by the Second Ecumenical Council, which assembled there in 381, and condemned Macedonius, Archbishop of Constantinople, the enemy of the Holy Spirit. When Saint Gregory came to Constantinople, the Arians had taken all the churches and he was forced to serve in a house chapel dedicated to Saint Anastasia the Martyr. From there he began to preach his famous five sermons on the Trinity, called the Triadica. When he left Constantinople two years later, the Arians did not have one church left to them in the city. Saint Meletius of Antioch (see Feb. 12), who was presiding over the Second Ecumenical Council, died in the course of it, and Saint Gregory was chosen in his stead; there he distinguished himself in his expositions of dogmatic theology.

Having governed the Church until 382, he delivered his farewell speech - the Syntacterion, in which he demonstrated the Divinity of the Son - before 150 bishops and the Emperor Theodosius the Great; in this speech he requested, and received from all, permission to retire from the see of Constantinople. He returned to Nazianzus, where he lived to the end of his life, and reposed in the Lord in 391, having lived some sixty-two years.

His extant writings, both prose and poems in every type of metre, demonstrate his lofty eloquence and his wondrous breadth of learning. In the beauty of his writings, he is considered to have surpassed the Greek writers of antiquity, and because of his God-inspired theological thought, he received the surname "Theologian." Although he is sometimes called Gregory of Nazianzus, this title belongs properly to his father; he himself is known by the Church only as Gregory the Theologian. He is especially called "Trinitarian Theologian," since in virtually every homily he refers to the Trinity and the one essence and nature of the Godhead. Hence, Alexius Anthorus dedicated the following verses to him:

Like an unwandering star beaming with splendour,
Thou bringest us by mystic teachings, O Father,
To the Trinity's sunlike illumination,
O mouth breathing with fire, Gregory most mighty.

Our righteous Mother Xenia of Petersburg was born about the year 1730. She was married to a Colonel named Andrew; when she was twenty-six years old, her husband died suddenly, having been drinking with his friends. Left a childless widow, Xenia gave away all that she had, and vanished from Saint Petersburg for eight years; it is believed that she spent this time in a hermitage, learning the spiritual life. When she returned to Saint Petersburg, she wore her husband's military clothing, and would answer only to the name Andrew, that is, the name of her late husband. She took up the life of a homeless wanderer, and was abused by many as insane; she bore this with great patience, crucifying the carnal mind through the mockery she endured, and praying for her husband's soul. She was given great gifts of prayer and prophecy, and often foretold things to come; in 1796 she foretold the death of Empress Catherine II. Having lived forty-five years after her husband's death, she reposed in peace at the age of seventy-one, about the year 1800. Her grave became such a source of miracles, and so many came to take soil from it as a blessing, that it was often necessary to replace the soil; when a stone slab was placed over her grave, this too disappeared over time, piece by piece. Saint Xenia is especially invoked for help in finding employment, lodging, or a spouse.

Our righteous Mother Xenia of Rome was of a distinguished family. While her parents were preparing to wed her, she stole away secretly, taking two handmaids with her, and departed for Mylasa of Karia in Asia Minor, and there she completed her life in asceticism. She was ordained deaconess by Paul, her spiritual father, who became Bishop of Mylasa. Although she was originally named Eusebia, to conceal her identity, she took the name Xenia - which means "stranger" in Greek - because of her estrangement from her country.

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.
