It’s on this page http://www.maryundoerofknots.com/history.htm
It describes sin as “the knot of disgrace for the human race”, and claims that “Mary, by her obedience, undid it”.
I’ve seen the page.
I have not seen there she undid the knot of sin, which is your claim.
I'm increasingly coming to the conclusion that the reason so many RC's fall such sad prey to such hideous blasphemy and idolatry . . . is because . . .
instead of a steady vision of CHRIST LIFTED UP . . .
AND THEN CHRIST AND HIS TRAIN FILLING THE TEMPLE . . .
All they see is the RC edifice and all the idols and similar distractions.
ANYONE WHO HAS EVER HAD AN EMPHATIC, IMPACTFUL, BURNING-TO-THE-BONE-MARROW VISION OF THE RISEN CHRIST
won't settle for cheap UNBiblical also rans . . . of any sort or name . . . ever again.
Maybe that should be more our prayer focus . . . less against, per se, satan's tool with the Magnificent Magical Earth-Mother Mary caricature . . . and more that they see CHRIST LIFTED UP . . . to the point that they realize . . . woe is me, a man of unclean lips and fingers.
