Saint Sebastian
Martyr
Sanctified Life
c. 255 AD — c. 288 AD
Milan, Roman Empire (also attributed to Narbonne, Gaul)
Also Known As
"You are guilty of the most cruel injustice when you persecute the servants of Christ, whom you know to be innocent."
Saint Sebastian concealed his Christianity while serving as captain of the Praetorian Guard under Diocletian and Maximian, using that access to strengthen imprisoned Christians. Shot with arrows and left for dead on the Field of Mars, he survived — nursed back by Irene of Rome — and returned to rebuke Diocletian to his face. The emperor had him clubbed to death, earning Sebastian the name 'the twice-martyred saint.'

Life & Times
Early Life
Born around 255 AD in Narbonne (or Milan), Sebastian moved to Rome around 270 and enlisted in the army in 283, rising to captain of the Praetorian Guard and using that position to secretly support Christians imprisoned under Diocletian.
Turning Point
Exposed as a Christian, he was bound to a stake and shot with arrows — left for dead on the Field of Mars. Nursed back to health by Irene of Rome, he chose to return and confront Diocletian directly rather than flee.
Legacy
Clubbed to death on Diocletian's order, his remains were buried near the Appian Way by the widow Lucina. The basilica Pope Damasus I raised over his tomb became a center of Roman pilgrimage, and his intercession was credited with ending Rome's plague of 680 AD.

Words & Wisdom
Oration to Emperor Diocletian
According to the hagiographic Acts of Sebastian, after miraculously surviving the arrow martyrdom, Sebastian returned to Diocletian and publicly denounced the persecution of Christians. The speech survives only in this later legendary source, not in any contemporary record.
O Blessed Sebastian, who on earth didst fight manfully for the faith of Christ, and who in heaven hast received the crown of martyrdom as a reward, intercede for us before the throne of the Most High. By your glorious martyrdom obtain for us the grace of a lively faith, an ardent charity, and a burning desire of immortal glory. Assist us, we beseech you, in our dangers and temptations, that guided and protected by you, we may safely pass through the trials of this life and arrive safely at eternal life. Amen.
