Nowhere in Scripture does Mary intercede with Jesus for us Arthur.
Nowhere in Scripture does God - or anyone else - call Mary the Mother of God.
Why add to His Word? It is sufficient as He inspired it.

At the wedding feast at Cana, Mary tells Jesus, “They have no wine.” He tells her it is not time yet for him to reveal his divinity by performing a miracle. Mary knows that he is going to do it, anyway, because she has asked him, so she tells the stewards, “Do whatever he tells you.” And Jesus responds to her request.
The gospel does not tell us about this incident just to make chit-chat. The gospels were written to tell about the realities of the spiritual economy.
We who are in need (the couple who are out of wine) go to Mary to make our needs known to her. Mary intercedes with her Son, and he responds to her requests.
Mary’s function as an intercessor for us with Jesus is taught to us in the gospel account of the wedding feast at Cana.
