There is nothing, I mean nothing in the NT, that ascribes to Mary the abilities, perogatives, etc that he, or other catholic writers have written.
The Bible does have this to say about her.
Mary was the mother of Jesus. She was a humble bondslave of our Lord. She knew her OT as evidenced by her prayer recorded in Luke. She was a "good" girl in that she had not engaged in extra marital sex prior to her marriage with Joseph. She and Joseph followed the Law as they offered the sin sacrifice after Jesus was born. She and Joseph raised Jesus. She saw her Son rejected and crucified by the leadership of the day. She also knew her Son was resurrected on the third day. She was in the Upper Room and was able to see the birth of the church that would be built around her Son.
She is blessed among women and she will always be remembered in that capacity.
All right dear ealgeone, it’s clear St. DeMontfort’s writings do not agree with your opinion of what the NT says (and doesn’t say). What would it hurt, though, to take his advice (and mine) as previously described? He (and I) are literally onky saying to pray to God directly for discernment from the Holy Spirit. Nothing about Mary in Paragraph 2. Only God. Directly. Do as you wish however.
I would like to end by commending you. In this post you at least demonstrate more respect and, dare I say veneration of Mary than others on this thread. For that you are to be commended.
May you have a joyous Christmas season.
