I think you put your finger on what is the main problem with Marian doctrines .Instead of allowing the Scriptures to form doctrines, feelings and speculations are the factors that determine what Mary should look like and be for people.
The Scriptures could not form doctrines, the doctrines were in place before the first epistle was ever written.
This was a problem for Israel in the OT. Instead of following the Word of God they followed their speculations about God and were rebuked by God for idolatry.
What Scriptures did the Israelites have when they left Egypt and wandered in the desert for 40 years?
It is very harmful when you do not follow the Scriptures and allow speculations of men to determine what Mary is like and your relationship is to be with her. It was so harmful to Israel that God through the prophet Jeremiah rebuked those people who burned sacrifices to the queen of heaven and were punished by God for doing so. See Jeremiah 44:15-29
It is very harmful when you limit yourself to the written Word of God and discard the Tradition from whence it came. The Scriptures do tell us what our relationship is with her. Revelation 12 tells us about the woman who gave birth to “a male child, one who is to rule all the nations with a rod of iron,” which is Jesus Christ. It goes on to say “her offspring” are “those who keep the commandments of God and hold to the testimony of Jesus.” It’s really quite logical. God is Jesus’ Father and our Father. Jesus is our brother since we have been adopted into His family. It logically follows that Jesus’ mother is our mother. It’s not really complicated, and it’s very Scriptural.
Queen of Heaven
In Jeremiah 7:18, God is indeed upset with the Israelites for worshipping a false goddess called the “queen of heaven”. However, just because God rebuked them for worshipping the false queen of heaven, doesn’t mean that we cannot pay honor to the true Queen of Heaven…the Blessed Mother.
That type of thinking would lead you to believe that just because people worship a false god that they call “god,” we, therefore, should not call the true God, by that same name…God…because that’s the same title the idolaters use for their god! That is faulty logic and it makes no sense whatsoever.
Again, the fact that there is a false “queen of heaven”, does not lead to the conclusion that we worship a false goddess when we call Mary the “Queen of Heaven.” Just as the fact that there is a false “god”, does not lead to the conclusion that we worship a false god when we call our Father in Heaven, God.
And there is a true Queen of Heaven, we see this quite clearly in Revelation 12:1, “And a great portent appeared in heaven, a woman clothed with the sun, with the moon under her feet, and on her head a crown of twelve stars…” Let’s see. There’s a woman…she’s in Heaven…and she has a crown on her head. I could be wrong, but I don’t think it’s the maid!
