So then you can understand where Mary gets her title as Queen, yes?
I am really leery of this title, and trying to read the Davidic queens as a prototype of Mary. The premier example seems to be 1 Kings 2, and the requester, Adonijah, winds up getting executed for asking through the Queen Mother - not exactly how we want our prayers answered. I have not found anything that convinces me the title is appropriate.
That being said, if anyone would get a big reward in heaven, I would think it would be Mary, and I for one would not begrudge her any honor God is happy to give her. If she showed up at my door she would certainly be a welcome guest and I would do my best to make her feel comfortable.
AND the adopted sons and daughters of God are exactly that - members of a royal household, and in that sense essentially the same as Mary, with varying degrees of honor and glory as the Father is pleased to give them.
I don’t think the mystery of the Trinity could ever be fully articulated.
Augustine, Basil, Hilary of Poitiers and others have given it a pretty good shot. I don’t know if Athanasius wrote the Athanasian creed, but there is that as well.
Your position is a Protestant position.
I simply showed you that there are some other Protestants (most of them, in fact) who say that Jesus is indeed King, not just God the Father is King.
Now you are getting into the technical differences between the members of the Trinity. The ONLY difference between the Father and the Son is that the Son is generated by the Father, and the ONLY difference between the Father and the Spirit is that the Spirit is sent. I’ll stay away from the filioque here. They share honor, regency, glory, rule, etc.
Mary, as a creature, will never be equal to the Creator. But your assigning meaning to queen of heaven vs “Queen of Heaven” is an arbitrary assignation.
The typical Protestant reaction to the phrase “Queen of heaven” is that there the Catholics go committing idolatry again. I don’t think you are shutting the door to error when you use that phrase, even among Catholics. I watched with fascination a discussion between a priest and a particular Catholic. The PC was insistent that Mary was divine: full-fledged deity, and calling her anything less was an insult to her. I don’t think the priest really got through to the PC. The PC used the titles of Mary, including QoH, to demonstrate her divine nature, and insisted also that being the Mother of God meant she must also be God. I think a lot of Marian theology can be dangerous and lead people into error with misleading and flowery language. Certainly a lot of it is a stumbling block to Protestants who take it at face value, and to Catholics as well, who are not necessarily well catechized.
