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.

Saint Macarius the Great was from the Thebaid of Egypt, a disciple, as some say, of Saint Anthony the Great. He was born about 331 and struggled in asceticism in the desert at Scete. Although young, he was called "the child elder" because of his great wisdom and austere manner of life. He was ordained presbyter and reposed in 391, at the age of sixty. There are fifty homilies ascribed to him.

It is said of Saint Macarius that he became as a God upon earth, for even as God protects the whole world, so did he cover the faults he saw as if he did not see them. Once he came back to his cell to find a thief taking his things and loading them on a camel. Macarius' non-possessiveness was so great that he helped the thief load the camel. When the camel refused to rise, Macarius returned to his cell and brought a small hoe, said that the camel wanted the hoe also, loaded it on, and kicked the camel telling it to get up. The camel obeyed Macarius' command, but soon lay down again, and would not move until everything had been returned to Macarius. His contemporary, Saint Macarius of Alexandria, was so called because he came from Alexandria and was therefore of that Greek-speaking colony; while Saint Macarius the Great is also called "of Egypt," that is, he belonged to the ancient race native to Egypt, the Copts.

The great teacher and invincible defender of the One, Holy, Catholic, and Apostolic Church, Saint Mark, was the offspring and scion of the imperial city, Constantinople. Reared by most pious parents, and instructed in secular and spiritual wisdom, he became preeminent in both. Saint Mark lived as an ascetic on the Prince's Islands and later in the monastery of Saint George Magana in Constantinople. He passed through all the degrees of the priesthood, and was finally advanced to the dignity of Archbishop and the lofty throne of the Metropolis of Ephesus. At the insistence of Emperor John Paleologos, the Saint was sent to the council of the Latins in Florence, to unite the churches that had been divided for so many years. He astounded the papal teachers with the divine wisdom of his words, and was the only one who did not sign the blasphemous decree of that false council. Because of this, the Holy Church of Christ has ever honored this great man as a benefactor, teacher, sole defender, and invincible champion of the Apostolic Confession. He reposed in 1443.

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.
