I believe that the Catholic Church believes she is the Queen of Heaven... I DO NOT believe that the WORD OF GOD backs that up in any way.
I think using "earthly" kingdoms to try to devise some order for Mary in Heaven is a joke, since Christ changed EVERYTHING about all of that when He came. He changed all of the Old Testament obligations of blood and the traditions of man such as KINGS and such.
His Kingdom will reign forever... a new Jerusalem, a NEW Heaven and Earth, and a King of Kings.... LORD OF LORDS... who will have no queen... but a bride who will rule and reign with him.
Since when in marriage, is the mom over the wife? Show me where that is in any testament... in Genesis God commanded that marriage would be before even parents.
Jesus has a bride, that is us, the body, the blood bought saints of the living God... not His mother.
Some word mixed in with perspective would be nice.
