** I thought that He was not a respector of persons.**
You think that Jesus Christ would not respect his Mother? You need to rethink your words, perhaps.
If Jesus was subject to Mary and Joseph on earth, and He is true God, then it makes sense that He would still, in accordance with His will, would hear the intercession of, at the very least, Mary and St. Joseph.
Did PleaseNoMore even read this part of the article at the start of this thread? I will refer you to the Book of Exodus where very specific instructions are given for the construction of the Ark. If God specified that with the Ark that contained His written word, one must think that He would have had taken as much, if not more care, for the New Ark that bore the Word Made Flesh.
While you may think "behold your mother" literally means that He intended for His statement to mean that she was the mother of all Christians, I believe that He was doing what was customary for His time and seeing that Mary, a widow, was being cared for. Had He meant to "give" her to us as a mother or establish her as an important part of His church, he would have certainly said so. If this is the case why didn't any of the disciples or Paul, who addressed so much, ever mention Mary again in such a manner?
Mary is incapable of performing miracles. She is incapable of interceding on our behalf. She cannot bless us. She cannot protect us. She can't do anything for us. She is dead. I believe that Mary, an humble servant of God, would be embarassed by the glory and, in some cases, the Christ like status assigned to her by some.
