Born in Nicomedia of a Christian mother, Eubula, and a pagan father, Eustorgius, Panteleimon studied medicine as a young man. The priest Hermolaus befriended him, instructed him in the Christian faith and baptized him. Panteleimon miraculously healed a blind man whom other doctors had treated in vain; he healed him by the name of Christ and baptized him. From jealousy, the doctors denounced Panteleimon as a Christian, and he went before the Emperor Maximian for judgment. He stood before the earthly ruler in the body, but in his mind he stood before the heavenly King. He freely declared himself to be a Christian before the Emperor, and, in front of his eyes, healed a paralytic of a long infirmity. This miracle brought many of the pagans to the Christian faith. The Emperor put him to torture, but the Lord appeared to him on several occasions and delivered him whole and uninjured. Then St. Hermolaus suffered along with Hermippus and Hermocrates. Condemned to death, St. Panteleimon knelt in prayer. At that, the executioner gave him a blow on the neck with his sword, and the sword broke as if made of wax. The executioner could not kill him until he had finished his prayer and had himself given the word to behead him. Panteleimon was beheaded under an olive tree, which after that became laden with fruit. "Panteleimon" means "all-merciful." God the all-merciful received his righteous soul, and glorified him among His greatest saints, his relics remaining incorrupt. This wonderful martyr suffered with honor as a youth for Christ on July 27th, 304. St. Panteleimon is invoked in the prayers at the blessing of water and the blessing of oil, together with St. Hermolaus and the other unmercenaries and wonderworkers. The loveliest church dedicated to him is found on the Holy Mountain.
Troparion, Tone 3
O holy prize-winner and healer Panteleimon,/ intercede with our merciful God/ that He may grant to our souls/ the forgiveness of our sins.
Kontakion, Tone 5
Thou didst faithfully follow the Merciful One/ and wast granted the grace of healing./ O prize-winner and Martyr of Christ our God/ by thine intercessions/ heal the diseases of our souls/ and banish the snares of the enemy/ from those who cry with faith: Save us, O Lord.
