When the wine was gone, Jesus’ mother said to him, “They have no more wine.” “Woman, why do you involve me?” Jesus replied. “My hour has not yet come.” His mother said to the servants, “Do whatever he tells you.” Nearby stood six stone water jars, the kind used by the Jews for ceremonial washing, each holding from twenty to thirty gallons.
The first miracle was recorded at a wedding. Marriage was clearly an important institution for Jesus. Mary and Joseph had an unusual marriage in which a non-judgemental love was taught by the Holy Spirit. Marriage is a pattern for Christ's relationship with the church. Jesus held that divorce was only permitted because of the hardness of heart of the participants.
I suspect the whole village was invited because Jesus' newly acquired companions were invited with him and a huge amount of water was changed into wine.
Don't be offended by Jesus calling his mother, "Woman"; it was a term of respect, but he was also telling her that there was to be a separation between his time at home and his time in his ministry.
Jesus was not an ascetic; he drunk the wine that was part of the staple diet. It was undoubtedly fermented, but it was not the strong wine that we are used to today. Getting drunk was not Jesus' style.
