Saint Proclus lived during the reign of Saint Theodosius the Younger. A disciple and scribe of Saint John Chrysostom, he was ordained Bishop of Cyzicus about the year 426, but because the people there unlawfully elected another bishop before his arrival, he remained in Constantinople. In 429, Nestorius, who had been Archbishop of Constantinople for about a year, and had already begun his blasphemous teaching that it is wrong to call the holy Virgin "Theotokos," invited Bishop Proclus to give a sermon on one of the feasts of our Lady, which he did, openly defending in Nestorius' presence the name "Theotokos," that is, "Mother of God." Saint Proclus was elevated to the throne of Archbishop of Constantinople in 434. It was he who persuaded Emperor Theodosius the Younger and his holy sister Pulcheria to have the most sacred relics of his godly teacher Saint John Chrysostom brought back from Comana, and triumphantly received them upon their return to the imperial city (see Jan. 27 and Nov. 13). He reposed in peace in 447.

According to the tradition of the Church, the Theotokos was brought to the Temple at three years of age, where she was consecrated to God and spent her days until she was fourteen or fifteen years old; and then, as a mature maiden, by the common counsel of the priests (since her parents had reposed some three years before), she was betrothed to Joseph.

Saint Cecilia was of an illustrious Roman family. On being betrothed to Valerian, she drew him to the Faith of Christ, and he in turn drew his own brother Tiburtius to the same. They contested in martyrdom during the reign of Diocletian, in the year 288.

Saint Gregory, the son of pious parents named Chariton and Theodora, was born in Agrigentum, a city of Sicily, and was great in virtue from his childhood. He was baptized, brought up, and tonsured reader by Bishop Potamion during the reign of Justinian II, in the seventh century. At the age of eighteen he made a pilgrimage to Jerusalem, where he was ordained deacon by Macarius, Bishop of Jerusalem. He traveled to Constantinople, and then to Rome where he was consecrated Bishop of his native Agrigentum. As Bishop of Agrigentum he worked many miracles and shone brilliantly in virtue, but also suffered many great temptation; from the priests Sabine and Crescentius, who so envied him that they slandered him to the Pope as a fornicator and had him cast into prison for two and a half years. In the end, however, he vindicated himself by casting the demon out of the woman who had falsely accused him of committing sin with her. Saint Gregory reposed in peace in deep old age.

Saint Clement was instructed in the Faith of Christ by the Apostle Peter. He became Bishop of Rome in the year 91, the third after the death of the Apostles. He died as a martyr about the year 100 during the reign of Trajan.

Saint Catherine, who was from Alexandria, was the daughter of Constas (or Cestus). She was an exceedingly beautiful maiden, most chaste, and illustrious in wealth, lineage, and learning. By her steadfast understanding, she utterly vanquished the passionate and unbridled soul of Maximinus, the tyrant of Alexandria; and by her eloquence, she stopped the mouths of the so-called philosophers who had been gathered to dispute with her. She was crowned with the crown of martyrdom in the year 305. Her holy relics were taken by Angels to the holy mountain of Sinai, where they were discovered many years later; the famous monastery of Saint Catherine was originally dedicated to the Holy Transfiguration of the Lord and the Burning Bush, but later was dedicated to Saint Catherine. According to the ancient usage, Saints Catherine and Mercurius were celebrated on the 24th of this month, whereas the holy Hieromartyrs Clement of Rome and Peter of Alexandria were celebrated on the 25th. The dates of the feasts of these Saints were interchanged at the request of the Church and Monastery of Mount Sinai, so that the festival of Saint Catherine, their patron, might be celebrated more festively together with the Apodosis of the Feast of the Entry of the Theotokos. The Slavic Churches, however, commemorate these Saints on their original dates.

Saint Alypius was from Adrianople of Bithynia; having lived upon a pillar for fifty-three years, he reposed about the year 607, at the age of one hundred.

This Saint was from the city of Bythlaba and was of noble birth; he was the closest and most honoured friend of Isdiger (or Yazdegerd) I, King of Persia (reigned 399-420). Though a Christian from his youth, James renounced Christ because he was allured by the King's friendship and flatteries. When his mother and his wife learned of this, they declared to him by letter that they would have nothing more to do with him, since he had preferred a glory that is temporal to the love of Christ. Wounded in soul by these words and coming to himself, the Saint wept over his error, and repudiated the worship of the idols. Therefore, becoming exceedingly wroth, the King - this was Bahram (or Varahran) V (reigned 421-438), Isdiger's son and successor - condemned him to a most bitter death, the likes of which not even a brute beast was ever condemned to: that is, his body was dismembered at every joint of his arms and legs. And so, when he had been cut asunder limb by limb to his very hips and shoulders, the courageous Martyr was finally beheaded, in the year 421.
