As he entered Capernaum, a centurion came forward to him, beseeching him and saying, “Lord, my servant is lying paralyzed at home, in terrible distress.” And he said to him, “I will come and heal him.” But the centurion answered him, “Lord, I am not worthy to have you come under my roof; but only say the word, and my servant will be healed. For I am a man under authority, with soldiers under me; and I say to one, ‘Go,’ and he goes, and to another, ‘Come,’ and he comes, and to my slave, ‘Do this,’ and he does it.” When Jesus heard him, he marveled, and said to those who followed him, “Truly, I say to you, not even in Israel have I found such faith. I tell you, many will come from east and west and sit at table with Abraham, Isaac, and Jacob in the kingdom of heaven, while the sons of the kingdom will be thrown into the outer darkness; there men will weep and gnash their teeth.” And to the centurion Jesus said, “Go; be it done for you as you have believed.” And the servant was healed at that very moment. (Matthew 8:5-13)
“The Lord’s reaction must have surprised those who witnessed the scene. He declares that He has not found such great faith in Israel; those chosen to be the children of the kingdom would be cast out and replaced by others. Finally, He tells the centurion to go his way and that his servant is healed. St.Ambrose sees the healing by the Lord’s word alone as proof of His equality with the Father: ‘…as the Father spoke the Son made, so, too, the Father works and the Son speaks’. And St.Basil the Great emphasizes that it was the Savior’s word and not His presence that healed the sick man.
The centurion is a striking figure. He enters the narrative as a man already possessed of a deep faith in Jesus’ power to heal, even by a word. He asks nothing for himself but only for his servant, his social and military inferior. His status notwithstanding, he feels profoundly his own unworthiness.” (Archbishop Dmitri, The Miracles of Christ, pg. 15)
