So what if he would? It was stated in Genesis by God that he will put "enmity between him (the serpent) and the Woman".
The woman mentioned is Eve, not Mary. From:

ccording to this verse, there will be enmity between the individual woman (Eve) and the serpent who deceived her. The word enmity indicates a blood feud. There will also be enmity between his seed and her seed. God promised that eventually the serpent would bruise the heel of the seed of the woman. However, the seed of the woman would also bruise (or crush) the head of the serpent. This will be a fatal blow. Who is the seed of the woman and who is the seed of the serpent? What do these predictions mean?
The ultimate seed of the woman would be Jesus Himself. Therefore, we have in Genesis 3:15, the first promise of a Redeemer. It is the beginning of a long line of prophecies concerning the coming Messiah. The Promised One would be from the woman's seed an indication of the eventual virgin birth of Christ.
The reason why it is necessary to believe what we claim about her is because when you read the Bible in full, rejecting her being sinless leaves a lot of contradictory to scripture than the other way around. You can find verses in the NT where Jesus calls her Woman... which is a reference to that verse in Genesis.
Can you post some of this scripture? I have never seen anything in the Word of God that would be invalidated if Mary was not a virgin after Christs birth and was a normal human that sinned.
I also see no scripture to validate an interpretation that would indicate Mary to be a perpetual virgin or sinless.
Here is a verse that catches her in the act of sinning: Mary thought He was insane. Is that not a sin?
Mark 3:21 mentions some persons that said Jesus had lost his senses. Does the text say Jesus’ kinsmen said he was mentally ill or was it others outside the family?
Answer: The author of Mark divides his narrative into two scenes in 3:20-35. One scene takes place where Jesus resides (verses 20, 22-35) the other is where his “kinsmen” are to be found (verse 21). It was these kinsmen, his mother and brothers, who “went out to take custody of him [Jesus].” One does not take custody of someone who is well. They felt Jesus had lost his mind. In order to take custody of him they had to go where he was residing. As a result, the text says, “. . . his own kinsmen . . . went out to take custody of him . . . .” In verse 31 the narrative describes their arrival at the place where Jesus was staying.
Jesus is told that his mother and brothers are outside looking for him. His Answer, “Who are my mother and my brothers? . . . For whoever does the will of God, he is my brother and sister and mother,” (verses 33-35) shows that he was hostile to their attempt to see him. There could be but one reason. His family, mother brothers, and sisters, believed him to be mentally ill and had not come simply to see him, but had come to seize him.
If you take a look in the OT with the Ark of the Covenant, God instructed that the Ark was to be FULLY clean. No sinful hands could touch it because it contained the 10 commandments - which was considered the Holy of Hollies. Now if this God touched covenant was to be completely clean from sin what more for a greater Holy of Hollies - his son. The New and Everlasting Covenant?
No body could touch it because The Ark of the Covenant was an embodiment of God's presence with the Israelites. The atonement cover (or "mercy seat") that covered the ark was God's throne (
2 Sam 6:2) and God's presence was above it (
Lev 16:2); it was also the place where God met Moses and gave him commands (
Ex 25:22). If someone approached the ark, they would effectively be in God's presence - a sinner standing before a holy God who does not tolerate evil (
Ps 5:4-6) - and would die as a result of their sins. Not because the 10 commandments were in there. If this were the case, how did Moses and others touch the 10 commandments in the first place. Also, the ark was dangerous before they were put inside.
The 10 commandments were not considered the holy of hollies. The tent area where the ark was kept was this most holy place.
Jesus was both God and Man and as our children are innocent in utero so was Jesus. This is why Mary could live and carry the infant Jesus.
