Hilary of Poitiers — as excerpted in the Catena Aurea on John 2:5-11

“(iii. de Trin. c. 5) Water is poured into the waterpots; wine is drawn out into the chalices; the senses of the drawer out agree not with the knowledge of the pourer in. The pourer in thinks that water is drawn out; the drawer out thinks that wine was poured in. When the ruler of the feast had tasted the water that was made wine, and knew not whence it was, (but the servants who drew the water knew,) the governor of the feast called the bridegroom. It was not a mixture, but a creation: the simple nature of water vanished, and the flavour of wine was produced; not that a weak dilution was obtained, by means of some strong infusion, but that which was, was annihilated; and that which was not, came to be.”
