Matthew 8:13

Then, that no one might suppose His words to come of flattery, but that all might be aware that such was the mind of the centurion, He saith, "Go thy way; as thou hast believed, so be it done unto thee." And straightway the work followed, bearing witness to his character. "And his servant was healed from that hour." Which was the result in the case of the Syrophoenician woman also; for to her too He saith, "O woman, great is thy faith; be it unto thee even as thou wilt. And her daughter was made whole."

But nevertheless, unto this great and marvellous work the centurion too contributed no little; which thing, we see, Christ also declared, saying, "Go thy way, and as thou hast believed, so be it done unto thee." Seest thou how the health of the servant proclaimed aloud both Christ's power, and the faith of the centurion, and also became a pledge of the future? Or rather it was all a proclamation of Christ's power. For not only did He quite heal the servant's body, but the soul also of the centurion He did Himself bring over unto the faith by His miracles. And do thou look not to this only, that the one believed, and the other was healed, but marvel how quickly also. For this too the evangelist declared, saying, "And his servant was healed in the self-same hour:" even as of the leper also he said, "he was straightway cleansed." For not by healing, but by doing so both in a wonderful manner and in a moment of time, did He display His power. Neither in this way only doth He profit us, but also by his constant practice, in the manifestation of His miracles, of opening incidentally His discourses about His kingdom, and of drawing all men towards it. For, those even whom He was threatening to cast out, He threatened not in order to cast them out, but in order that through such fear, He might draw them into it by His words. And if not even hereby were they profited, theirs is the whole blame, as also of all who are in the like distemper.

(Serm. 62. 2.) As the Lord did not enter the centurion's house with His body, but healed the servant, present in majesty, but absent in body; so He went among the Jews only in the body, but among other nations He was neither born of a Virgin, nor suffered, nor endured human sufferings, nor did divine wonders; and yet was fulfilled that which was spoken, A people that I have not known hath served me, and hath obeyed me by the hearing of the ear. (Ps. 18:43.) The Jews beheld, yet crucified Him; the world heard, and believed.

As though He had said, According to the measure of thy faith, so be thy grace. For the merit of the Lord may be communicated even to servants not only through the merit of their faith, but through their obedience to rule. It follows, And his servant was healed in the self-same hour.
