“And Jesus said unto the centurion, Go thy way; and as thou hast believed, so be it done unto thee. And his servant was healed in the selfsame hour.”
Matthew 8:13 — Greek Interlinear
Church Fathers on Matthew 8:13
As what the leper had affirmed concerning Christ’s power, 'If thou will, thou canst cleanse me,' was confirmed by the mouth of Christ, saying, 'I will, be thou clean;' so here He did not blame the centurion for bearing testimony to Christ’s authority, but even commended him. Nay more; it is something greater than commendation that the Evangelist signifies in the words, 'But Jesus hearing marvelled.'
Observe how great and what that is at which God the Only-begotten marvels. Gold, riches, principalities, are in His sight as the shadow or the flower that fadeth; in the sight of God none of these things is wonderful, as though it were great or precious, but faith only; this He wonders at, and pays honour to, this He esteems acceptable to Himself.
But who was He that had created this faith in him, but only He who now marvelled at it? But even had it come from any other, how should He marvel who know all things future? When the Lords marvels, it is only to teach us what we ought to wonder at; for all these emotions in Him are not signs of passion, but examples of a teacher.
