When the wine ran out, Jesus' mother said to him, "They have no wine."

 The word woman (gunai, G1135) is also misleading. It sounds to us very rough and abrupt. But it is the same word as Jesus used on the Cross to address Mary as he left her to the care of John ( John 19:26). In Homer it is the title by which Odysseus addresses Penelope, his well-loved wife. It is the title by which Augustus, the Roman Emperor, addressed Cleopatra, the famous Egyptian queen. So far from being a rough and discourteous way of address, it was a title of respect. We have no way of speaking in English which exactly renders it; but it is better to translate it Lady which gives at least the courtesy in it.
