And that which you quoted does not state that she “is the source of salvation.” anywhere, not directly and not even indirectly.
If you aren’t going to read what I wrote, or read what I was responding to, what is the point of this conversation?
Saying "she provided the Savior" (= salvation) is at least indirectly saying she “is the source of salvation.” As others assert, "to her, Jesus owes His Precious Blood" (http://www.salvemariaregina.info/SalveMariaRegina/SMR-098.html) and "We are all debtors to God, but He is a debtor to you" even though Christ is her creator. And that "We were condemned through the fault of one woman; we are saved through the merits of another woman" and who "had to suffer, as He did, all the consequences of sin." and who is "all-powerful in saving sinners" "no one who can be saved or redeemed but through thee," "and therefore we have recourse, to thee alone," "we have but one advocate, and that is thyself, and thou alone art truly loving and solicitous for our salvation" and “sometimes salvation is quicker if we remember Mary's name then if we invoked the name of the Lord Jesus" "when she acts, it is also He who acts; and that if her intervention be not accepted, neither is His..." “The power thus put into her (Mary’s) hands is all but unlimited." (Sources).
