3. How could Mary be sinless if in the words of the Magnificat she said that her soul rejoices in God her savior?
The Church does not hesitate to profess that Mary needed a savior. This should be the first issue to address if this question arises. It was by the grace of God—and not the work of Mary—that she was saved from sin in a most perfect manner. By what is called “preservative redemption,” Mary was preserved from sin at the time of her natural conception. John the Baptist was sanctified in the womb prior to his birth (Luke 1:15), and Mary was sanctified at her conception. It is no difficulty that Christ distributed the grace of Calvary some forty-five years or so before it happened, just as he bestows it upon us two thousand years after the fact. The Catechism of the Catholic Church states that this gift was given to Mary, making her “redeemed in a more exalted fashion, by reason of the merits of her Son” (492). She has more reason to call God her Savior than we do, because he saved her in an even more glorious manner!
God can “save” a person from a sin by forgiving them, or by providing them the grace never to fall into that particular sin. An ancient analogy is often useful to explain this: A person can be saved from a pit in two ways; one can fall into it and be brought out, or one can be caught before falling into it. Mankind is saved in the first manner, and Mary in the second. Both are saved from the pit of sin. If Jesus wished to save his mother from the stain of sin, what is to prevent him?

AMEN!
None of this is in the Bible. And being sanctified has nothing to do with never sinning. Even John the Baptist sinned. Being sanctified is being set apart by The LORD for His purpose. It does not mean that one cannot nor will never sin. Also, if Christ could save us from sinning before we ever did even one sin why would he not do it for each of us?
Rom 3:23 For ALL have sinned, and come short of the glory of God; ((Emphasis mine.)) Rom 3:23 For all have sinned, and come short of the glory of God;
Rom 3:24 Being justified freely by his grace through the redemption that is in Christ Jesus:
Rom 3:25 Whom God hath set forth [to be] a propitiation through faith in his blood, to declare his righteousness for the remission of SINS THAT ARE PAST, through the forbearance of God; ((Emphasis mine to show that the sins were past and therefore had been committed. Not kept from ever being committed,))
John in the Bible clearly says that for anyone to say that they have not sinned is a lie. He did not say except Mary the mother of Jesus our LORD whom Christ had given to his care at the time of His death.
1Jo 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
1Jo 1:9 If we confess our sins, he is faithful and just to forgive us [our] sins, and to cleanse us from all unrighteousness.
1Jo 1:10 If we say that we have not sinned, we make him a liar, and his word is not in us.
