Rome would have people believe that Christ not only got his human nature from Mary, but also some sort of perfection from her, too.
And that's a lie. All and only perfection came from the Holy Spirit.
From Mary Christ was able to know and understand sin and to feel the depth of it because Mary was a sinner just like the rest of mankind.
For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings." -- Hebrews 2:9-10
" For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him." -- 2 Corinthians 5:21 "But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
Rome bows down to the creature when God's word tells us ALL the glory belongs to God ALONE.
Catholics believe Christ is "true God and true Man", His human and divine natures perfectly united in one Person -- not 50% of each in some weird amalgamation. Perhaps you'd assign different percentages , , , or perhaps you wouldn't assign a "percentage" to "true God" at all . . .
You do still seem to be using circumlocutions to avoid saying that Christ is God.
From Mary Christ was able to know and understand sin and to feel the depth of it because Mary was a sinner just like the rest of mankind.
This you have made up from whole cloth -- and follow it with apparently randomly generated scripture verses as if they were the source or the confirmation, which they are not.
