FWIW, you are cursed by the RCC because of this belief.
Canon 24: "If any one saith, that the justice received is not preserved and also increased before God through good works; but that the said works are merely the fruits and signs of Justification obtained, but not a cause of the increase thereof; let him be anathema."
FWIW, I can't find the book of Canon in my Bible. FWIW, I can find that Jesus is the ONLY mediator between God and man, so praying to Mary is blasphemy to God. I can find where Bishops are to have one wife and you shouldn't deny to marry. I can find that you aren't supposed to add or subtract from the Bible. I can find where the church of the 7 hills is the Whore of Babylon and God begs you to come out of her. I can't find any popes, nuns, monks, or cardinals, etc, mentioned in my Bible.
