Stumped on that one were ya?
Not even close. I just tire of having to explain Catholic theology at the grade school level on an adult forum, but here it goes just like I explain it to kids.
If you fell into quick sand and I pulled you out I would be saving your life. If I prevented you from falling into that same quick sand I would be saving you nonetheless.
Similarly, most if us hope to be saved from our sins by Jesus after we have committed them. Mary was preserved and saved from sin before she committed them. That is certainly no less miraculous than any other Salvation. I know it goes against the Protestant grain to believe that there are some treated differently by God than others, that it is "unfair" and counter to their democratic (lower case D) mindset. In this respect Catholics display a characteristic humility.
Peace be with you.
