You realize your post 129 makes the point of intersession. If Mary simple prodding of her son Jesus caused him to do something he originally did not intend to do and yet did it. That is Love for ones Mother and speaks wonders to have Mary petitioning Jesus for you.
Will you also pray to an unnamed Greek woman as your intercessor? Mary's not the only woman who seems to have convince Jesus to do what he had not intended.
As someone else posted on this thread -
Mark 7:24-30
Jesus left that place and went to the vicinity of Tyre. He entered a house and did not want anyone to know it; yet he could not keep his presence secret. In fact, as soon as she heard about him, a woman whose little daughter was possessed by an impure spirit came and fell at his feet. The woman was a Greek, born in Syrian Phoenicia. She begged Jesus to drive the demon out of her daughter.
“First let the children eat all they want,” he told her, “for it is not right to take the children’s bread and toss it to the dogs.”
“Lord,” she replied, “even the dogs under the table eat the children’s crumbs.”
Then he told her, “For such a reply, you may go; the demon has left your daughter.”
She went home and found her child lying on the bed, and the demon gone.
Did it ever occur to Catholics that it could just have been that Mary went to Jesus about the wine not knowing HOW He was going to handle it? We can look at it in hindsight but that colors our perspective. Try putting yourself in that situation without any preconceived notions of what was going to happen.
Marriage suppers were family affairs in those days. It could very well be that somehow Mary was connected with hostessing the supper and when they ran out of wine, she came to Him to have Him deal with procuring more in the normal way, presumably because she knew that if she asked Him to do something, she could trust Him because He had proved Himself dependable.
I don’t think there’s anything in Scripture to indicate that she expected Him to deal with in any way out of the ordinary, that is sending someone out to buy more.
