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.

Saint Hermolaus and those with him were priests of the Church in Nicomedia, living in hiding after the Emperor Maximian had burnt to death the 20,000 Martyrs of Nicomedia (see Dec. 28). It was Hermolaus who converted Saint Panteleimon to Christ. When Saint Panteleimon was seized as a Christian and was asked by Maximian who it was that had turned him from the idols, the Saint, enlightened by God that the time of his teacher's martyrdom also was at hand, revealed to Maximian that it was Hermolaus the priest. Saint Hermolaus was taken with Saints Hermippus and Hermocrates, and when they had confessed Christ to be the only true God, they were beheaded in the year 305. Saint Hermolaus is one of the Holy Unmercenaries.

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.
