Why then did our Lord change the nature of water in the first of his
signs? Was it not to show that the divinity, which had changed nature
in the depths of the jars, was that same divinity that had changed
nature in the womb of the Virgin? At the completion of his signs he
opened the tomb to show that the greed of death had no hold over him. He
sealed and confirmed these two uncertainties, that of his birth and of
his death. For these waters, with regard
to their nature, were transformed into the fruit of the vine, but
without the stone jars themselves undergoing change in their nature
inwardly. This was a symbol of his body, which was wondrously conceived
in a woman, and, without a man, miraculously formed within the Virgin.
He made wine from water, therefore, in order to give proof concerning
how his conception and his birth took place. He summoned "six water
jars" as witness to the unique virgin who had given birth to him. The
water jars conceived in a novel way, not in keeping with their custom,
and gave birth to wine. But they did not continue to give birth.
Similarly the Virgin conceived and gave birth to Emmanuel, and she did
not give birth again. The giving birth by the jars was from smallness to
greatness and from paucity to abundance; from water indeed to good
wine. In her case, however, it was from greatness to weakness and from
glory to ignominy. Those jars were for the purification of the Jews, but
our Lord poured his teaching into them, so that he might make it known
that he was coming through the path of the Law and the Prophets to
transform all things by his teaching, just as he had transformed water
into wine.
