Our righteous Father Sergius was born in Rostov, north of Moscow, about the year 1314. Named Bartholomew in Baptism, he was brought up in Radonezh, and at the death of his parents he withdrew to the wilderness to become a monk. It is notable that without having been trained in a monastery, he was of such a spiritual stature as to be able to take up the perilous eremitical life from the beginning, without falling into delusion or despondency. When he had endured with courage the deprivations of the solitary life, other monks began to come to him, for whom he was made abbot against his will. On the counsel of Philotheus, Patriarch of Constantinople, he organized his monks according to the cenobitic life, appointing duties to each. While Anthony and Theodosius of Kiev, and the other righteous Fathers before Sergius, had established their monasteries near to cities, Sergius was the leader and light of those who went far into the wilderness, and after his example the untrodden forests of northern Russia were settled with monks. When Grand Duke Demetrius Donskoy was about to go to battle against the invading Tartars, he first sought the blessing of Saint Sergius, through whose prayers he was triumphant. Saint Sergius was adorned with the highest virtues of Christ-like humility and burning love for God and neighbour, and received the gift of working wonders, of casting out demons, and of discretion for leading souls to salvation. When he served the Divine Liturgy, an Angel served with him visibly; he was also vouchsafed the visitation of the most holy Theotokos with the Apostles Peter and John. He was gathered to his Fathers on September 25, 1392. At the recovery of his holy relics on July 5, 1422, his body and garments were found fragrant and incorrupt. His life was written by the monks of Epiphanius, who knew him.

This Apostle was from Bethsaida of Galilee, and was the son of Zebedee and Salome, and the brother of James the elder. First a fisherman by trade, he became an Apostle and the beloved Disciple of Christ. Only he of all the Disciples followed Him even to the Cross, and was entrusted with the care of our Saviour's Mother, as it were another son to her, and a brother of Christ the Teacher. After this, he preached throughout Asia Minor, especially in Ephesus. When the second persecution against the Christians began in the year 96 during the reign of Domitian, he was taken in bonds to Rome, and there was cast into a vat filled to the brim with boiling oil. Coming forth therefrom unharmed, he was exiled to the island of Patmos, where he wrote the Book of Revelation. Returning again to Ephesus after the death of the tyrant, he wrote his Gospel (after the other Evangelists had already written theirs) and his three Catholic Epistles. In all, he lived ninety-five years and fell asleep in the Lord during the reign of Trajan in the year 100. He was called Theologian because he loftily expounded in his Gospel the theology of the inexpressible and eternal birth of the Son and Word of God the Father. It is for this cause that an eagle-a symbol of the Holy Spirit, as Saint Irenaeus says-is depicted in his icon, for this was one of the four symbolic living creatures that the Prophet Ezekiel saw (Ezek. 1:10).

This Saint, a Parthian by race, was the son of Anak. He was born about the year 240 and was taught the Faith of Christ in Caesarea of Cappadocia. He entered the service of Tiridates, King of Armenia, but when discovered to be a Christian, he was subjected to many horrible torments at the King's hands, then was cast into a pit of mire with poisonous serpents and left to die. By the power of God, however, he abode there unharmed for fourteen years, his needs provided by a certain widow, until he was made known by revelation and set free. He converted to piety innumerable multitudes of Armenians, including Tiridates himself, and was consecrated bishop by Leontius, Archbishop of Caesarea, to shepherd the vast flock he had gained for Christ. He spent the last part of his life in retirement in the ascetical discipline, and reposed in peace about the year 325. Saint Gregory is honoured as the Illuminator of Armenia.

Saint Romanos flourished during the reign of Anastasius (491-518). He was from Emesa of Syria, and apparently was born of Jewish parents, for a hymn written in his honour in Greek says he was "of Hebrew stock," and it has furthermore been noted that he uses many Semitic idioms in his writings. He was baptized an Orthodox Christian, and at some time became a deacon in the Church of Beirut. He was the first composer of the kontakia, the foremost of which is that of the feast of Christ's Nativity, On this day the Virgin .... In composing many of his kontakia. Saint Romanos was inspired by the hymns of Saint Ephraim of Syria.
