Martyr Sebastian and Companions at Rome

He grew up in Milan and became an army officer, where he distinguished himself so well that the Emperor Diocletian made him captain of the Praetorian Guard not suspecting that Sebastian was a Christian. In Rome, while fulfilling the duties of a courtier, he used his position to comfort and encourage his imprisoned fellow-Christians. By his labors and example he brought many to faith in Christ, including Chromatius, the Prefect in charge of persecuting the Roman Christians.
