Every human being is greater than an any angel, archangels included. That was the whole point of the Epistle to the Hebrews. Some believe that the elevation of human nature over angels provoked Satan to rebel. The BVM was truly an instrument of salvation as the Mother of God; however, Mary was a sinner like all human beings. She plays a very small part in the Scriptures when compared with Jesus and the apostles. How many times is Mary even mentioned outside the gospels? The Marian Cult is based more upon superstition than reality.
The Lord her Savior did this for her.
Using the analogy of, say, quicksand, one can be saved from quicksand in two ways: by being pulled out of it, or by being prevented from falling into it. We who are saved by Christ are saved in the first way, by being pulled out of the heritable consequences of Original Sin. Mary needed a Savior too, to save her the second way: by preventing her from falling in.
How do we know that? Because of the title by which the Archangel from Heaven addressed her, Kecharitomene: that says it all.
And because the Archangel said, "The Lord is with you." Not "the Lord BE with you," but "IS" with you. Scripture says (Psalm 5) "You are not a God who delights in wickedness; evil cannot dwell with You./The sinful cannot stand in Your presence; You hate all evildoers."
So Mary, His dwelling-place, had nothing to do with wickedness; He does not dwell in the presence of sin.
You say: "How many times is Mary even mentioned outside the gospels? The Marian Cult is based more upon superstition than reality."
I know what you mean. I used to think the same way, before I realized that there is a profound, Christ-centric way to read the Old Testament, a way explained by the Lord Himself.
Jesus refers to this when he is talking to the disciples on the road to Emmaus: "Beginning with Moses and all the Prophets, He interpreted to them in all the Scriptures the things referring to Himself." (Luke 24:27)
It turns out that all of the OT -- every book ---refers to Christ, and every book, likewise, contains foreshadowings of Mary: from
Are you a disciple of Christ? Then stand with Mary and John at the foot of the Cross, when Jesus says to John and to us, "Behold, your Mother."
Happy New Year to you!
