John 2:3

In the ancient times there was prophecy, and no times were left without the dispensation of prophecy. But the prophecy, since Christ was not understood therein, was water. For in water wine is in some manner latent. The apostle tells us what we are to understand by this water: "Even unto this day," saith he, "whilst Moses is read, that same veil is upon their heart; that it is not unveiled because it is done away in Christ. And when thou shalt have passed over," saith he, "to the Lord, the veil shall be taken away." By the veil he means the covering over of prophecy, so that it was not understood. When thou hast passed over to the Lord, the veil is taken away; so likewise is tastelessness taken away when thou hast passed over to the Lord; and what was water now becomes wine to thee. Read all the prophetic books; and if Christ be not understood therein, what canst thou find so insipid and silly? Understand Christ in them, and what thou readest not only has a taste, but even inebriates thee; transporting the mind from the body, so that forgetting the things that are past, thou reachest forth to the things that are before. Wherefore, prophecy from ancient times, even from the time when the series of human births began to run onwards, was not silent concerning Christ; but the import of the prophecy was concealed therein, for as yet it was water. When these words of the Gospel are understood, and they are certainly clear, all the mysteries which are latent in this miracle of the Lord will be laid open. Observe what He says, that it behoved the things to be fulfilled in Christ that were written of Him. Where were they written? "In the law," saith He, "and in the prophets, and in the Psalms." He omitted no part of the Old Scriptures. These were water; and hence the disciples were called irrational by the Lord, because as yet they tasted to them as water, not as wine. […]

When Christ was present at the marriage feast, and the crowd of guests were faring sumptuously, The supply of wine failed them, and their joy was turned into distress; The bridegroom was upset; the cupbearers muttered unceasingly; There was this one sad display of penury, …

Seasonably comes He at length, to the beginning of miracles, even if He seems to have been called to it without set purpose. For a marriage feast being held (it is clear that it was altogether holily), the mother of the Saviour is present, and Himself also being bidden comes together with His own disciples, to work miracles rather than to feast with them, and yet more to sanctify the very beginning of the birth of man: I mean so far as appertains to the flesh. For it was fitting that He, Who was renewing the very nature of man, and refashioning it all for the better, should not only impart His blessing to those already called into being, but also prepare before grace for those soon to be born, and make holy their entrance into being. Receive also yet a third reason. It had been said to the woman by God, In sorrow thou shalt bring forth children. How then was it not needful that we should thrust off this curse too, or how else could we escape a condemned marriage? This too the Saviour, being loving to man, removes. For He, the Delight and Joy of all, honoured marriage with His Presence, that He might expel the old shame of child-bearing. For if any man be in Christ, he is a new creature; and old things are passed away, as Paul saith, they are become new. He cometh therefore with. His disciples to the marriage. For it was needful that the lovers of miracles should be present with the Wonderworker, to collect what was wrought as a kind of food to their faith. But when wine failed the feasters, His mother called the Lord being good according to His wonted Love for man, saying, They have no wine. For since it was in His Power to do whatsoever He would, she urges Him to the miracle.

Here it is worth while to enquire whence it came into His mother's mind to imagine anything great of her Son; for He had as yet done no miracle, since the Evangelist saith, "This beginning of miracles did Jesus in Cana of Galilee." Now if any say that this is not a sufficient proof that it was the "beginning of His miracles," because there is added simply "in Cana of Galilee," as allowing it to have been the first done there, but not altogether and absolutely the first, for He probably might have done others elsewhere, we will make answer to him of that which we have said before. And of what kind? The words of John (the Baptist); "And I knew Him not; but that He should be made manifest to Israel, therefore am I come, baptizing with water." Now if He had wrought miracles in early age, the Israelites would not have needed another to declare Him. For He who came among men, and by His miracles was so made known, not to those only in Judaea, but also to those in Syria and beyond, and who did this in three years only, or rather who did not need even these three years to manifest Himself (Matt. iv. 24), for immediately and from the first His fame went abroad everywhere; He, I say, who in a short time so shone forth by the multitude of His miracles, that His name was well known to all, was much less likely, if while a child He had from an early age wrought miracles, to escape notice so long. For what was done would have seemed stranger as done by a boy, and there would have been time for twice or thrice as many, and much more. But in fact He did nothing while He was a child, save only that one thing to which Luke has testified (Luke ii. 46), that at the age of twelve years He sat hearing the doctors, and was thought admirable for His questioning. […]

"How then," asks some one, "came it into the mind of His mother to imagine anything great of Him?" He was now beginning to reveal Himself, and was plainly discovered by the witness of John, and by what He had said to His disciples. And before all this, the Conception itself and all its attending circumstances had inspired her with a very great opinion of the Child; "for," said Luke, "she heard all the sayings concerning the Child, and kept them in her heart." "Why then," says one, "did not she speak this before?" Because, as I said, it was now at last that He was beginning to manifest Himself. Before this time He lived as one of the many, and therefore His mother had not confidence to say any such thing to Him; but when she heard that John had come on His account, and that he had borne such witness to Him as he did, and that He had disciples, after that she took confidence, and called Him, and said, when they wanted wine, "They have no wine." For she desired both to do them a favor, and through her Son to render herself more conspicuous; perhaps too she had some human feelings, like His brethren, when they said, "Show thyself to the world" (c. xvii. 4), desiring to gain credit from His miracles.
