The holy Passion-bearers Boris and Gleb, named Romanus and David in sacred Baptism, were the pious sons of the holy Great Prince Vladimir. In 1015 they were slain at the command of their brother Svyatopolk-Saint Boris, on July 24 on the Alta River, near Pereyaslavl, and Saint Gleb, on September 5 on the bank of the Smyadinya River, near Smolensk. Although both had understood their brother's designs against them, they refused to take up arms against him and bring civil war upon their land, preferring to fulfill the commandment, "Resist not evil" (Matt. 5:39). The holy relics of Saint Boris were then buried in Vyshgorod, to which the holy relics of his brother were transferred five years later. Miracles were worked through the holy relics of the meek and guileless brothers during the consecration in Vyshgorod of a church in their honor on this day in 1021.

Saint Paraskeve, who was from a certain village near Rome, was born to pious parents, Agatho and Politia. Since she was born on a Friday (in Greek, Paraskeve), she was given this name, which means "preparation" or "preparedness" (compare Matt. 27:62, Mark 15:42, Luke 23:54, and John 19:31, where 'Friday' is called "the day of the preparation"). From childhood she was instructed in the sacred letters and devoted herself to the study of the divine Scriptures, while leading a monastic life and guiding many to the Faith of Christ. During the reign of the Emperor Antoninus Pius, she was apprehended because she was a Christian and was urged to worship the idols, but she answered with the words of Jeremias: "Let the gods that have not made heaven and the earth perish from off the earth" (Jer. 10:11). Because of this she endured exceedingly painful torments, and was beheaded in the year 140. The faithful pray to her for the healing of eye ailments.

This Saint, who had Nicomedia as his homeland, was the son of Eustorgius and Eubula. His father was an idolater, but his mother was a Christian from her ancestors. It was through her that he was instructed in piety, and still later, he was catechized in the Faith of Christ by Saint Hermolaus (see July 26) and baptized by him. Being proficient in the physician's vocation, he practiced it in a philanthropic manner, healing every illness more by the grace of Christ than by medicines. Thus, although his parents had named him Pantoleon ("in all things a lion"), because of the compassion he showed for the souls and bodies of all, he was worthily renamed Panteleimon, meaning "all-merciful." On one occasion, when he restored the sight of a certain blind man by calling on the Divine Name, he enlightened also the eyes of this man's soul to the knowledge of the truth. This also became the cause for the martyrdom of him who had been blind, since when he was asked by whom and in what manner his eyes had been opened, in imitation of that blind man of the Gospel he confessed with boldness both who the physician was and the manner of his healing. For this he was put to death immediately. Panteleimon was arrested also, and having endured many wounds, he was finally beheaded in the year 305, during the reign of Maximian. Saint Panteleimon is one of the Holy Unmercenaries, and is held in special honor among them, even as Saint George is among the Martyrs.

Saint Irene, who was from Cappadocia, flourished in the ninth century. Because of her great beauty and virtue, she was brought to Constantinople as a prospective bride for the young Emperor Michael (842-867); however, as Saint Joannicius the Great foretold, it was God's will that she assume the monastic habit instead. She shone forth in great ascetical labours, and suffered many attacks from the demons; while yet a novice, she attained to the practice of Saint Arsenius the Great, of praying the whole night long with arms stretched out towards Heaven (see May 8). God showed forth great signs and wonders in her, and she became the Abbess of the Convent of Chrysovalantou. She was granted the gift of clairvoyance and knew the thoughts of all that came to her. She appeared in a vision to the king and rebuked him for unjustly imprisoning a nobleman who had been falsely accused. Through a sailor from Patmos to whom he had appeared, Saint John the Evangelist sent her fragrant and wondrous apples from Paradise. She reposed at the age of 103, still retaining the youthful beauty of her countenance. After her repose, marvelous healings beyond number have been wrought by her to the present day.
