You do know you are the one who asked about Her? I merely provided a possible solution to your inquiry. I believe in the Holy Trinity, the Triune God too.
The Blessed Virgin Mary is Special and Holy, isn't She? She's all about God in Her Messages. God this, God that, God left, God right, God up, God down, God here, God there, God in, God out, God front, God back. She's all about God. I just find Her Utterly Terrific.
My thinking is this. If this Woman named Mary is not suppose to be important, and God is Almighty and can do anything He wants, why would He even need to be carried by the Woman in Her Womb? That's just ridiculous.
Angel Gabriel could have just come to Mary and given Her a Baby and tell Her, "This is God, the Son, look after Him. God don't need no human vessel to pop Him out. He is Almighty and can pop in and out of worldly existence just through His Word. So here is Baby Jesus Christ, He has just been popped into my Arms by God the Father and I present Him to you to look after Him because that is God's Will. You are just His adoptive mother, understand woman? Don't go assuming you're more important than anybody else. You're just a nobody looking after the Redeemer of the World. You're not special. I have to go back to God now. Can't spend all day talking to a nobody like you. Make sure you don't pass any of your human, crappy, diseased, sinful nature and condition to Baby Jesus Christ. You will contaminate Him with your nothingness. That will be totally gross and you will ruin the Plan of Redemption for the whole human race. Got it, Mary? Bye." This is what a lot of people say about Her which makes no sense at all to me.
Mary is more than just a mortal woman. I would not be surprised if She had a pre-existent life. If you look at God's attitude in regards to marriage and procreation, it is solemn and serious in nature. So for God to have a Son through this Woman named Mary, this Woman just by that Deed and Act of God Almighty is Holy. This Woman named Mary while married to Joseph but before they lived together put God first before Her own husband, Joseph to have God's Son. She's like committing adultery with God to bear His Son. But it's not adultery only if this Woman named Mary was married to God first. Otherwise God would be breaking His Own Law. So Mary is one spirit and then one flesh with God. Even Jesus Christ, Her Son talks about the Sanctity of Marriage. Joseph was the adopted husband of Mary and adopted father of Jesus because God willed it so. So basically Joseph was looking after God's Wife and Son because God Himself was not able to do so at that particular point in time.
This Woman named Mary is the Spouse and Mother of Almighty God and Has a Spiritual Connection with the Holy Trinity that nobody else have. Angel Gabriel Hailed Her. Angel Gabriel doesn't hail nobodies. Angel Gabriel did not hail Zechariah, the priest, who was just a worshipper of God, that's all. Zechariah despite being righteous in the eyes of God and even prayed for a baby was not able to believe Angel Gabriel while Mary, who was married to Joseph despite hearing the most ridiculous announcement from anybody in Her entire life believed Angel Gabriel.
Anyway, you don't have to believe in Her. It's done by faith, by choice. Jesus Christ is more than enough for most. It's just that I came to faith in Jesus Christ through Her so I'm one of Her son. She has power over me and I like it that way because She teaches me about God.
God bless you.
