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.
Archimandrite Justin Popovich said:
“Do you know when a man is wise in the sight of Christ the Lord? When he listens to His word and carries it out. The beginning of wisdom is to listen to God’s word (Matt. 7:24-25). Every word of the Savior has the power and the might to heal both physical and spiritual ailments. ‘Say the word and my servant will be healed’ (Matt. 8:8). The Savior said the word – and the centurion’s servant was healed. Just as He once did, the Lord even now ceaselessly says His words to you, to me, to all of us. But we must pause, and immerse ourselves in them and receive them – with the centurion’s faith. And a miracle will happen to us, and our souls will be healed just as the centurion’s servant was healed. For it is related in the Gospel that they brought many possessed people to Him, and He drove out the spirits with a word, and healed all the sick (Matt. 8:16).
