Saint George lived about the beginning of the ninth century in Palestine, in a certain monastery called Hozeva, which lies in a great ravine between Jerusalem and Jericho.

Saint Domnica was from Carthage. During the reign of the Emperor Theodosius the Great, she came with four other virgins to Constantinople, where she was baptized by Nectarius, the Patriarch of Constantinople. She remained in Constantinople and became known for her extreme asceticism, the miracles that she worked, and the grace of prophecy that adorned her. She lived until the days of the Emperors Leo and Zeno, reposing in peace about the year 474.

Saint Polyeuctus, a soldier in rank, contested during the reign of Valerian, in the year 255. He was from Melitene, a city in Armenia.

Saint Gregory, the younger brother of Basil the Great, illustrious in speech and a zealot for the Orthodox Faith, was born in 331. His brother Basil was encouraged by their elder sister Macrina to prefer the service of God to a secular career (see July 19); Saint Gregory was moved in a similar way by his godly mother Emily, who, when Gregory was still a young man, implored him to attend a service in honor of the holy Forty Martyrs at her retreat at Annesi on the River Iris. Saint Gregory came at his mother's bidding, but being wearied with the journey, and feeling little zeal, he fell asleep during the service. The Forty Martyrs then appeared to him in a dream, threatening him and reproaching him for his slothfulness. After this he repented and became very diligent in the service of God.

Gregory became bishop in 372, and because of his Orthodoxy he was exiled in 374 by Valens, who was of one mind with the Arians. After the death of Valens in 378, Gregory was recalled to his throne by the Emperor Gratian. He attended the Local Council of Antioch, which sent him to visit the churches of Arabia and Palestine, which had been defiled and ravaged by Arianism. He attended the Second Ecumenical Council, which was assembled in Constantinople in 381. Having lived some sixty years and left behind many remarkable writings, he reposed about the year 395. The acts of the Seventh Ecumenical Council call him 'Father of Fathers."

This Saint had Cappadocia as his homeland. He lived during the years of Leo of Thrace, who reigned from 457 to 474. The Saint established in the Holy Land a great communal monastery, wherein he was the shepherd of many monks. While Saint Sabbas was the head of the hermits of Palestine, Saint Theodosius was governor of those living the cenobitic life, for which reason he is called the Cenobiarch. Together with Saint Sabbas, towards whom he cherished a deep brotherly love in Christ, he defended the whole land of Palestine from the heresy of the Monophysites, which was championed by the Emperor Anastasius and might very well have triumphed in the Holy Land without the opposition of these two great monastic fathers and their zealous defense of the Holy Council of Chalcedon. Having lived for 103 years, he reposed in peace.

Saint Tatiana was the daughter of a most distinguished consul of Rome. She became a deaconess of the Church, and for her confession of the Faith of Christ, she endured many torments. As she was suffering, angels punished her tormentors with the same torments they inflicted on her, until they cried out that they could no longer endure the scourges invisibly brought upon them. She was beheaded during the reign of Alexander Severus (111-135).

Saints Hermylus and Stratonicus contested for piety's sake during the reign of Licinius, in the year 314. Saint Hermylus was a deacon, and Stratonicus was his friend. For his confession of Christ, Hermylus was beaten so fiercely that his whole body was covered with wounds. Stratonicus, seeing him endure this and other torments that left him half dead, wept with grief for his friend. From this he was discovered to be a Christian, and when he had openly professed his Faith and had been beaten, he and Hermylus were cast into the Danube River, receiving the crown of martyrdom.

As for the holy Martyrs of Sinai and Raithu, those of Sinai contested during the reign of Diocletian, about the year 296; those of Raithu were slain about the middle of the fifth century. On both occasions, the perpetrators of these massacres were a barbarian tribe called Blemmyes, from the parts of Arabia and Egypt.

Because of the Apodosis of the Feast of Holy Theophany also on the 14th of January, the liturgical services to the Holy Fathers slain at Sinai and Raitho are transferred to January 13th.
