Luke’s Third Centurion appears in the Book of Acts 10: 1-8, 22-35, and 42-48:
5 And now send men to Joppa, and call for one Simon, whose surname is Peter:
8 And when he had declared all these things unto them, he sent them to Joppa.
25 And as Peter was coming in, Cornelius met him, and fell down at his feet, and worshipped him.
26 But Peter took him up, saying, Stand up; I myself also am a man.
27 And as he talked with him, he went in, and found many that were come together.
31 And said, Cornelius, thy prayer is heard, and thine alms are had in remembrance in the sight of God.
34 Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons:
35 But in every nation he that feareth him, and worketh righteousness, is accepted with him.
44 While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.
46 For they heard them speak with tongues, and magnify God. Then answered Peter,
A Centurion, a Roman Centurion, is Converted to Christianity-This is the headline from these readings.
As we have seen, the backbone of the Roman army was the centurions. So for a Centurion to be converted to Christianity was a very big deal. He is a key Roman official. He is, perhaps, the very symbol of the government.
Further, and extremely important, is the fact that during the time of Jesus, the headquarters of the Roman army in Judea was located at Caesarea, on the Mediterranean coast. Why was the army headquartered here? Caesarea Maritima was the capital of the province of Judea. Jerusalem was not the capital. Caesarea was the administrative hub of the province of Judea. Being posted here meant that the centurion was crucial to the proper functioning of the government, whether his force was providing security, as the head of a 80 man century, or whether he was higher up than a century commander.
So the events related by Luke in Acts are happening at the provincial capital-the very seat of Roman power and government in Judea. Let that sink in: The first Roman official converted to Christianity happens right at the seat of Roman power.
The third Centurion is both the first Gentile and the first Roman converted to Christianity. And he is a Roman official.
The story starts with the centurion being told by an angel to send for Peter. He does not question it. He immediately does what he is told to do. This is faith. His faith has been shown in other ways. He is devout. He fears the Lord. He prays to the Lord. He has given alms to the poor. He seeks baptism.
Conclusions:
Centurions led from the front. They led and inspired their men by example. They also sought to display the skill and courage that may have brought them to their rank in the first place. It is for these reasons that they often suffered a disproportionate number of casualties.
Remember that Centurions led by example. Again, remember that the most important and prestigious position an ordinary Roman citizen could hope to achieve was that of a centurion I think these facts are the clues which show why Luke is using these three stories of centurions, who are faithful, as a guide, as a map for other Gentiles to follow Jesus. Luke is saying follow the example of Centurions! If a Roman, if a Roman official, if a Gentile can believe in God, so too can you.
