Catholics set Mary up as the "Queen of Heaven". Catholics teach that Mary and the Apostles and even the so-called (and nominated/designated by men) Saints can intervene on someone's behalf. What a load of false doctrine that goes against all the is the Christ.
1) Jesus Christ - God Himself - chose to become incarnate through a human woman. He did not leave the choice of woman up to chance. No, God decided in advance to create a very special woman for this very special purpose. Remember, God would become a human - and this means He would be completely dependent on His human parents, and would be required by Torah to honor and obey His parents in everything they asked of Him. God decided to create a special woman for this reason. But remember, human beings were originally sinless. Eve was sinless. And in the future, God will glorify all of us who make it to Heaven, and we will be sinless forever. So when God made Mary "full of grace" He was not doing something unheard of. Being full of grace, there was no room for any sin, and God granted it to Mary that she would experience His salvation from the moment of her conception. That is why she calls Him her "Savior," because He saved her from experiencing sin and eternal death. He granted to her the grace of salvation from the moment of her conception, and He granted this grace to her in such a degree that she was "full of grace," "perfect in grace," with nothing but grace inside her. So Mary was given this blessing in order that God would be born through a fitting vessel. He was not going to become incarnate through a sinner. He was not going to subject Himself to an eternity of honoring and obeying a woman disposed to sin. As God, He is required to honor the woman who gave birth to Him. Our redemption depends on His perfect fulfillment of the Torah - and among the Laws in Torah is the law that a child must honor his father and mother. God must honor Mary, because Mary is the woman who gave birth to Him, and because of this God ensured that Mary would not be a sinful woman who would abuse this honor.
2) In the Old Testament, the Ark of the Covenant was a physical structure which contained the Old Covenant. Although the Ark was not the Covenant itself, it was still extremely holy and sacred because it carried the Covenant. The Ark of the Old Covenant was so precious to God that a man would die for even touching it. But the Old Covenant inside the Old Ark was only a shadow prefiguring the New Covenant to come. The holy and precious Ark of the Old Covenant would be nothing in comparison to the Ark of the New , because the Ark of the Old carried only a shadow, but the Ark of the New carried the substance: God Himself, God Almighty. The New Covenant is Jesus Christ, God incarnate, and the Ark of this Covenant is Mary. She carried God inside her womb. She carried the Covenant inside her womb. She is the New Ark. And if the Old Ark was so holy that a man would die for touching it, how much more holy is the Ark of the New, whom even carried the Lord God Jesus Christ inside her very own womb?
As David exclaimed when the Old Ark came to him, ""How can the ark of the Lord come to me?" (2 Sm 6:9), likewise, Elizabeth rejoices when the New Ark comes to visit her, as Luke records,
"And when Elizabeth heard the greeting of Mary, the babe leaped in her womb; and Elizabeth was filled with the Holy Spirit and she exclaimed with a loud cry, "Blessed are you among women, and blessed is the fruit of your womb! And why is this granted me, that the mother of my Lord should come to me?" (Lk 1:41-43). So then, Mary is the Ark of Our Lord Jesus Christ, the Ark of the New Covenant. And she is holy, and sacred, and of great precious value to our Lord.
3) Mary is both the Ark of the Lord and the Queen of Heaven, as the book of Revelation tells us.
"And the temple of God which is in heaven was opened; and the ark of His covenant appeared in His temple, and there were flashes of lightning and sounds and peals of thunder and an earthquake and a great hailstorm. A great sign appeared in heaven: a woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars; and she was with child; and she cried out, being in labor and in pain to give birth." (Rev 11:19-12:2)
You see how the Ark of God's Covenant appears in the temple, and lightening flashes, an earthquake rumbles, and a great hailstorm begins pouring down. And this was in preparation for the revealing of a great sign in Heaven: a woman clothed with the sun, clothed with extreme power, and the moon under her feet (even ruling over God's creation). On her head is a crown of twelve stars, representing the twelve tribes and twelve apostles, displaying that power to rule over creation has been granted to her by God, and to indicate who she was and why this great honor was bestowed upon her, we are told that "she was with child."
Mary is the Queen of Heaven. She is the Ark of the New Covenant. She is the most honored of all creatures. She is infinitely less worthy than Her son Jesus, who is God. She is only a creature. But! she has been granted a very special honor. She was made Ark of the New Covenant, and Mother of God, and was given to us all as our own Mother, and is now reigning as the Queen of Heaven.
When she prays to God Almighty, she does not approach Him in the same manner as us. She approaches as one who nursed Him at her breast. She approaches as one who shared in His suffering - a sword even pierced her own soul. Of all the Angels and Saints, of all creatures in the entire universe, Mary shares in Christ's love in a much deeper, more intimate, and more perfect and abiding way. And its not even close.
Christ loves Mary in a unique way. And Christ honors her as He would honor His own Mother. Because she is His Mother. So when she prays, Christ lovingly responds with the humble obedience of a loving son. And because He granted her the grace of salvation from the moment of her conception, because she was full of grace and kept entirely from sin all throughout her life, He is never disappointed by her holy requests. For when she prays, she prays from a soul that has never sinned, and she prays from a place of perfect love, and she only asks of Him the very things He already wants to do.
