Direct biblical statement
John 2:1–5
Do whatever he tells you
1 And the third day, there was a marriage in Cana of Galilee: and the mother of Jesus was there.
2 And Jesus also was invited, and his disciples, to the marriage.
3 And the wine failing, the mother of Jesus saith to him: They have no wine.
4 And Jesus saith to her: Woman, what is that to me and to thee? My hour is not yet come.
5 His mother saith to the waiters: Whatsoever he shall say to you, do ye.

Why this matters
Mary brings the absence of wine to Jesus and directs the servants to obey him. Jesus’ reference to his hour shapes the scene around his mission. Catholic tradition sees maternal intercession here; the narrative centers the sign on Christ.
