Augustine of Hippo
Catena Aurea · Matthäusevangelium 8
When Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you, I have not found so great faith, no, not in Israel. And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of Heaven. But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth. 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. PSEUDO-ORIGEN. (Hom. in Div. 5.) 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.
(super Gen. c. Man. i. 8.) 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 knew all thingsfuture? When the Lord 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.
