(December 31, December 18 old calendar).

The Holy Martyr Sebastian was born in Italy and brought up in the city of Milan. He was destined in his youth to be a soldier, and, as an educated, handsome and courageous man, commended himself to the Emperor Diocletian, who made him captain of the imperial guard. He secretly confessed the Christian faith, and prayed to the living God. An honorable, upright and merciful man, Sebastian was greatly loved by his soldiers. Whenever possible, he saved Christians from torture and death and, when this was not possible, gave them courage to die for Christ the living God without turning back. Two brothers, Marcus and Marcellinus, who were in prison for Christ and already on the verge of denying Him and worshipping idols, were confirmed in their faith and strengthened in their martyrdom by Sebastian. As he spoke with them, exhorting them not to fear death for Christ, his face was illumined like that of an angel of God. Sebastian supported his words by marvels: he healed Zoë, the wife of Nicostratus the jailer, who had been dumb for six years, and brought Nicostratus and his whole household to baptism; he healed the two sick sons of Claudius the commander, and brought him and his whole household also to baptism; he healed Tranquillianus, the father of Marcus and Marcellinus, of gout and pains in his legs which had troubled him for eleven years, and brought him to baptism together with his whole household; he healed the Roman Eparch, Chromatius, of the same infirmity and brought him and his son Tiburtius to baptism.

Of these, Zoë was the first to suffer, being seized while at prayer beside the tomb of the Apostle Peter. After torture, she was thrown into the river Tiber. Then Tiburtius was seized, and the judge placed live coals before him, challenging him to choose life or death: to cast incense on the coals and cense the idols, or to stand himself barefoot on the coals. St. Tibertius made the sign of the Cross and stood barefoot on the coals, and remained unharmed. He was then beheaded with the sword. Nicostratus was killed with a stake, Tranquillianus was drowned and Marcus and MarceiIinus were run through by spears. Then Sebastian was taken before the Emperor Diocletian. The Emperor rebuked him for his betrayal, but he said: 'I always pray to my Christ for your health, and for the peace of the Roman Empire.' The Emperor ordered that he be stripped and shot at with arrows. The soldiers then shot at him, until the martyr's whole body was so covered with arrows that it was invisible beneath them. When they thought that he was dead, he showed himself alive and healed of all his wounds. Then the pagans beat him to death with staves. He suffered gloriously for Christ his Lord and entered into the heavenly Kingdom in 287, when Gaius was Bishop of Rome.

O Sebastian, thou didst spurn the gatherings of the wicked/ and bring together the illustrious martyrs who with thee cast down the enemy./ Deemed worthy of the Divine Presence,/ thou dost gladden those who cry to thee:/ Glory to Him Who has strengthened thee; glory to Him Who has crowned thee;/ glory to Him Who through thee works healings for all.

Thou didst excel in godly zeal/ and gather a band of martyrs from which thou didst shine as a star./ The arrows that wounded thy body, O Sebastian,/ pierced the hearts of the enemy./ Hence Christ has glorified thee.
