Galileo, no doubt, would have pursed his lips at Cana—the classic miracle. Nature cannot transgress her laws: water cannot become wine. Perhaps, if he had been feeling scholastic, he might have suggested that the water merely took on the accidents of the wine, without changing its substance; a hundred years later he might have found some scientific approximation for the miracle, and trumpeted it up as a rational explanation. But here, for now, he would say that it mattered little about water and wine: the Bible simply wants us to know that Christ is the Lord our Saviour.
