Just as our Lord Jesus Christ is the true and Second Adam — the true man, through whom all humanity can become truly human — so also is Mary, the Mother of God (Theotokos) the true and second Eve. She is The Woman, through whose womb was salvation and the restoration of the cosmos to be wrought.
We see Jesus call upon his mother in this way in the Gospel According to John:
“And the wine failing, the mother of Jesus saith to him: ‘They have no wine.’ And Jesus saith to her: ‘Woman, what is that to me and to thee? my hour is not yet come.’ His mother saith to the waiters: ‘Whatsoever he shall say to you, do ye.’”
According to John 2:3-5 (Douay Rheims)
While some interpret this passage through modern language and culture — wrongly believing that Jesus has “rebuked” his own mother (which is a blasphemous accusation) — what Jesus is saying here is actually a great sign of respect. And indeed, Jesus obeys his mother, and does exactly as she says. The Mother of God in turn gives us the most important of precepts as followers of Christ: “Do whatever He tells you.”
