Mary said to Jesus: They have no wine…. Jesus answers her in words which are apparently harsh: Woman! what is it to me and to thee? My hour is not yet come. The meaning of these words is, that, in this great Mystery he was about to act, not as the Son of Mary, but as the Son of God. Later on, the hour will come when, dying upon the Cross, he will do a work, in the presence of his Mother, and he will do it as Man, that is, according to that human nature which he has received from her. Mary at once understands the words of her Son, and she says to the waiters of the Feast, what she is now ever saying to her children: Do whatsoever he shall say to you. (The Liturgical Year 3:242)
At Bethlehem, the Gold of the Magi expressed the Divinity of the Babe; at the Jordan, the descent of the Holy Ghost and the voice of the Eternal Father proclaimed Jesus (known to the people as a carpenter of Nazareth) to be the Son of God; at Cana, it is Jesus himself that acts, and he acts as God, for, says St. Augustine, he who changed the water into wine in the waterpots could be no other than the same who, every year, works the same miracle in the vine. Hence it was that, from that day, as St. John tells us, his disciples believed in him, and the Apostolic College began to be formed. (3:243)
