I have already posted a solid argument from scripture. There is no explicit verse that says "Mary was created free from original sin but by the same token there is no verse that says God is the Holy Trinity either but yet we believe and know with out a doubt that he is, how come?
Because the bible does conclude it implicitly through a consensus of verses.
And this constant, constant quoting of No one goes to the father but through me is redundant. WE KNOW THAT. We do not claim Mary went to God through any other way.
How could she have? She was the first Christian the world ever had. She received Christ in a way no other ever would or could, she was privileged to receive Christ in that way and be the first person to ever accept his merits for her own salvation which was given to her at her conception.
As far as solid bible evidence is concerned, in Genesis it begins. God tell the serpent because thou has done this that he will put enmities between him and the woman, between his seed which is corrupt and her seed which is also subject to corruption because all have sinned mankind is fallen at this point now but God will put enmities between her and Satan, she will not inherit this corruption.
Then God says to the serpent that he will lie in wait of her heel. Her obedience is going to crush his head. Gods plan to save us will not be thwarted because of Marys cooperation. Its not because Mary is so great and wonderful, but because God has made her according to His plan, because God made her this way.
Mary sinlessness is no credit to her, but is part of Gods plan of how he saved mankind from this fall.
In Luke we see the beginning of Satans downfall. The angel greets her as full of grace that the Lord is with her. He tells her she is to be the Mother of God and she says Let it be done
This was her fiat- right away she gave it to God, she gave her will and whole life in complete trust and obedience to Him in order that His plan of saving us will be accomplished. And then Satans head was crushed; hes only going down hill from there. He will be defeated when Christ dies and rises again.
At the moment of this fiat, Mary then receives Christ before any of us did. And we know she received Him because what is the first thing she does? She goes in haste to her cousin Elizabeths. This is definitely the sign of a person who has heard the word of God and received it, they go out in service to serve their fellow man. She didnt sit around saying, oh happy me, I get to be the mother of God.
And Elizabeth moved by the Holy Spirit exclaims, Blessed is the fruit of your womb
what is it that the mother of my Lord should come to me
at the moment John the Baptist heard her voice he was sanctified, he leaped for joy at the mere sound of her voice. Why? Because Mary brought Christ to him with the mere sound of her voice!
Then Mary gives her canticle. In it she says, My soul does magnify the Lord, my spirit rejoices in God my savior
How, if she was just a sinner like the rest can her soul magnify the Lord? Reflect God? How could she have rejoiced in God her savior when God her savior was still in her womb? He hadnt made His sacrifice for our sins yet. How can this be then?
Then Mary says God had regarded the humility of his servant. A fallen sinner humble? How can that be? We know sinners are born with the first sin, pride; the very opposite of humility.
The she says that God, who is mighty has done great things to her. Then she says from hence fourth all generations will call her blessed.
Wow, is all I can say when I read what the BIBLE has to say about Mary.
Then we see the relationship between Mary and Jesus, we see Mary bringing the 12 year old home with her when he says he has to be in his fathers house doing his fathers business and then we see Mary saying do what ever he tells you when Jesus says to the woman his hour has not come. Clearly Mary knew Jesus time. This shows us the very special connection they shared.
Then we see Mary at the cross with Jesus when all his other apostles left him accept for John and we see Jesus giving the woman to John, who represents all of us, the faithful followers of Christ.
Then in Revelation we see the appearance of the woman again. The woman is a great sign in heaven. If you notice this sign appears at the beginning of the chapter that tells us about the battle in heaven when Satan was kicked out.
He didnt like this Mary stuff either, he didnt like the idea of him not being able to influence her and control her through a fallen nature either. He didn't like the idea that he will not be able to stop her from bringing us the savior.
Revelation tells us, her sought after her to get her and her child but God protected her from Satan getting to her. So does what Satan do, he comes after us instead.
Genesis 3, Revelation 12, and Luke 1 for me, IS the solid evidence. That Satan sought after Mary and God protected her from him in order that we may be given a savior through her giving birth to Him.
