No "confusion" at all.
Mary IS the Queen of Heaven, according to Scripture.
Jesus Christ is the heir of David. He is the fulfillment of the covenant promises made to David in 2 Samuel 7:16; 23:5, and repeated to Mary in Luke 1:26-36. Mary’s son rules from the Kingdom of the heavenly Jerusalem. It is fitting that HIS mother should enjoy the same role that other Davidic Queen mothers enjoyed, that is the royal office of the heavenly Gebirah.
1 Kings 2:19-20 tells us:
So Bathsheba went to King Solomon to speak to him about Adonijah; the king got up to meet her and bowed before her; he then sat down on his throne; a seat was brought for the king’s mother, and she sat down on his right.
“There is one small favor I would ask of you,” she said. “Do not refuse me.” “Ask it, my mother,” the king said to her, “for I will not refuse you.”
Just as with the Davidic Kingdom, as Jesus is the King, Mary is the Queen Mother.
In the Book of Revelation, we see the New Ark of the Covenant in Heaven being spoken of at the very end of Chapter 11, verse 19:
Then God's temple in heaven was opened, and the ark of his covenant could be seen in the temple. There were flashes of lightning, rumblings, and peals of thunder, an earthquake, and a violent hailstorm.
The very next verse is in Chapter 12 (Rev 12:1):
A great sign appeared in the sky, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars.
Verse 2 says: She was with child and wailed aloud in pain as she labored to give birth.
We know that this child is Jesus because in verse 4, we read: She gave birth to a son, a male child, destined to rule all the nations with an iron rod.
There is simply NO getting around the fact that the Woman here in Revelation 12 is the Ark in Heaven, Mary.
