The wedding of Cana has been one of the most abused passages of Scripture by Roman Catholics to justify a whole range of false teachings regarding the Roman Catholic "Mary". Just what DID Mary say??
All the Words of Mary...
...as recorded in the Bible.
...To the angel
“How will this be,” Mary asked the angel, “since I am a virgin?”
Mary answered. “May it be to me as you have said.” (Luke 1:30-38)
...To Elizabeth
And Mary said: “My soul glorifies the Lord and my spirit rejoices in God my Savior, for he has been mindful of the humble state of his servant. From now on all generations will call me blessed, for the Mighty One has done great things for me—holy is his name. His mercy extends to those who fear him, from generation to generation. He has performed mighty deeds with his arm; he has scattered those who are proud in their inmost thoughts. He has brought down rulers from their thrones but has lifted up the humble. He has filled the hungry with good things but has sent the rich away empty. He has helped his servant Israel, remembering to be merciful to Abraham and his descendants forever, even as he said to our fathers.” (Luke 1:46-55)
...To Jesus
His mother said to him, “Son, why have you treated us like this? Your father and I have been anxiously searching for you.” (Luke 2:48-50)
... at Cana
And when the wine gave out, the mother of Jesus said to Him, “They have no wine.”
His mother said to the servants, “Whatever He says to you, do it” (John 2:3-5).
Mary is so central to the John 2 passage she's not even mentioned by name.
The only person who is mentioned by name is Jesus.
John tells us the purpose of this passage:
This beginning of His signs Jesus did in Cana of Galilee, and manifested His glory, and His disciples believed in Him. John 2:11 NASB
We also see something else very important in this verse...His disciples believed in Him.
In verse 12, which Roman Catholics seem to gloss over, we see Jesus, His mother and His brothers...meaning Joseph and Mary had children of their own.
What we do not see in the account at Cana.
People praying to Mary or coming to Mary for anything.
It is possible someone came to her about this or she saw this herself. The text is silent on the issue.
All we know is Mary came to Jesus and said, "they have no wine."
John does not record anyone at the wedding according anything special to Mary in regards to the wine being refilled. In v11 though he attributes this as the beginning of Jesus' signs...again, nothing to do with Mary.
To read into the text all that Roman Catholicism has is eisegesis...reading something into the text that isn't there.
It very often leads to very bad theology.
