And where did you get the notion that she was any kind of redeemer?
Not from the Bible!
how can anyone 'keep the Word' as Mary carried Christ in her womb? We can be likewise faithful to Christ and place ourselves at the foot of the Cross with St. John and Mary the Mother of God. We can let our soul magnify the Lord and let our spirit rejoice in God our Saviour. We can, in short, pray to her often, and ask for guidance.
That is not keeping the 'word' as Mary did keep the 'Word' in her womb.
Christ is clearly turning people away from venerating His mother The slight rebuke you detect in Jesus's voice is directed at those who might venerate Mary as purely a vessel, a breeding apparatus for God. This is, of course, a defect of Protestant, not Catholic, mariology. Still, veneration He approves, but He directs it at the true essence of Mary as the first and most faithful disciple, one without sin.
And where is Mary ever addressed as one without sin?
addresses her as 'woman'. He does, doesn't He? This echoes "the woman" whose seed will crush the Serpent (Genesis 3:15). It certainly has no connotation of disrespect, as historical scholarship showed, -- Forest Keeper made a post recently about this.
Christ doesn't call Mary, 'the woman' he calls her 'woman' instead of mother.
Moreover, I didn't say the term 'woman' had any connotation of disrespect, but neither does it have any connotation of superior respect either.
In fact, when Mary and Christ's brothers came to get Him, Christ said 'who is my mother or brethren'(Mk.3:33)
For There is one God and one mediator between God and men, the man Christ Jesus (1Tim.2:5)
From Luke 1, Genesis 3, Apocalypse 12 we know that Mary the Mother of God participates in salvation and so we call her a co-redeemer sometimes.
That is not keeping the 'word' as Mary did keep the 'Word' in her womb.
It is how we imitate her, because this is how Christ taught us to venerate her in Luke 11.

In Luke 1:28. Christ doesn't call Mary, 'the woman' he calls her 'woman' instead of mother ... Christ said 'who is my mother or brethren'(Mk.3:33)
Christ calls her "woman" because Genesis refers to "woman", whatever the grammatical framework happens to fit. Mark 3:33 repeats the call to sanctity through Mary also made in Luke 11, and already discussed.
Why don't you pick up the Catechism if you have these questions: Mary - Mother of Christ, Mother of the Church
