c. 356–360 · Hilary of Poitiers, On the Trinity (De Trinitate) 3.5
On the wedding day in Galilee water was made wine. Have we words to tell or senses to ascertain what methods produced the change by which the tastelessness of water disappeared, and was replaced by the full flavour of wine? It was not a mixing; it was a creation, and a creation which was not a beginning, but a transformation. A weaker liquid was not obtained by admixture of a stronger element; an existing thing perished and a new thing came into being. The bridegroom was anxious, the household in confusion, the harmony of the marriage feast imperilled.
