A Roman officer in command of a hundred men (Mark 15:39, 44, 45). Cornelius, the first Gentile convert, was a centurion (Acts 10:1,22). Other centurions are mentioned in Matthew 8:5,8,13; Luke 7:2, 6; Acts 21:32; Acts 22:25,26; Acts 23:17,23; Acts 24:23; Acts 27:1,6, 11,31,43; Acts 28:16. A centurion watched the crucifixion of our Lord (Matthew 27:54; Luke 23:47), and when he saw the wonders attending it, exclaimed, "Truly this man was the Son of God."
"The centurions mentioned in the New Testament are uniformly spoken of in terms of praise, whether in the Gospels or in the Acts. It is interesting to compare this with the statement of Polybius that the centurions were chosen by merit, and so were men remarkable not so much for their daring courage as for their deliberation, constancy, and strength of mind." - Dr. Maclear's N.
