Augustine of Hippo

(Tr. ix) This miracle of our Lord’s, turning the water into wine, is no miracle to those who know that God worked it. For the Same that day made wine in the waterpots, Who every year makes wine in the vine: only the latter is no longer wonderful, because it happens uniformly. And therefore it is that God keeps some extraordinary acts in store for certain occasions, to rouse men out of their lethargy, and make them worship Him. Thus it follows, He manifested forth His glory.
