Sebastian
December 18, Martyr, Σεβαστιανός
The holy martyr Sebastian was a Roman soldier of high rank who suffered under the persecution of Diocletian at the end of the third century. A secret Christian who strengthened imprisoned confessors, he was denounced, bound to a tree, and shot with arrows; found still living, he confessed Christ again before the emperor and was then put to death. A company of martyrs who suffered with him is honored alongside him.
