BTW, when you use the moniker Roman Catholic or RCC it is an automatic note to us that the true knowledge of the Catholic Church is not known. Please do look at these links:
And we, as Christians, are a "kingdom of priests" and are "saints", without need of an advocate, save for one, Christ Jesus himself, who makes daily intercession for His chosen. I need no man as mediator, as the Jews did, since the blood of bulls and goats merely covered the sin, but not removed it. But Christ, having offered one sacrifice for sins for all time, SAT DOWN AT THE RIGHT HAND OF GOD, ... For by one offering He has perfected for all time those who are sanctified.
And the Holy Spirit also testifies to us; for after saying, "THIS IS THE COVENANT THAT I WILL MAKE WITH THEM AFTER THOSE DAYS, SAYS THE LORD: I WILL PUT MY LAWS UPON THEIR HEART, AND ON THEIR MIND I WILL WRITE THEM," He then says, "AND THEIR SINS AND THEIR LAWLESS DEEDS I WILL REMEMBER NO MORE." Now where there is forgiveness of these things, there is no longer any offering for sin.
