The NT has no admonition to pray to Mary nor does it invoke Mary as mediatrix, advocate or redemtrix. None.
There is nothing indicating the wearing of a piece of cloth can somehow keep you from the hell-fire because you trust in what an apparition said.
If the roman catholic position on penance/purgatory is correct, that man somehow has to further cleanse himself through works, then Christ's death on the cross is somehow insufficient to cleanse us from all sins as John notes in 1 John 1. The Greek in that passage is clear He is the means of forgiveness for all of our sins.
There is no work we can do, other than believe, to atone for our sins.
Again, you make false statements:
“The NT has no admonition to pray to Mary nor does it invoke Mary as mediatrix, advocate or redemtrix. None.”
You should really study Catholic doctrine so that you are informed and not relying on the words of others or Satan.
You may understand better if one looks at things with a positive light (love of God and neighbor.
Does the Bible say we should approach the saints with our prayers? Yes, in two places. In Revelation 5:8 John saw the Lamb, Christ Jesus, on a throne in the midst of four beasts and 24 elders. When the Lamb took the book with the seven seals, the 24 elders fell down before the Lamb in worship, “each one having a harp and golden bowls of incenses, which are the prayers of the saints.”
Similarly, in Revelation 8:3-4 we are told that something similar happened when the Lamb opened the seventh seal of the book: “Another angel came and stood on the altar, having a golden censer, and many incenses were given to him, in order that he will give it with the prayers of all the saints on the golden altar before the throne. And the smoke of the incenses went up with the prayers of the saints from the hand of the angel before God.”
These texts give us a way to understand how the saints offer our prayers for us. Our prayers are like nuggets of incense. They smell sweet and good. The 24 elders around the throne, who are saints, and the angels offer these nuggets of incense for us. They set them on fire before the throne of God.
This is a beautiful image of how the intercession of the saints works. Because the saints are so close to the fire of God’s love and because they stand immediately before him, they can set our prayers on fire with their love and release the power of our prayers.
Its common sense. Scripture is very clear when it says, “But nothing unclean shall enter [heaven]” (Rev. 21:27). Hab. 1:13 says, “You [God]... are of purer eyes than to behold evil and cannot look on wrong...” How many of us will be perfectly sanctified at the time of our deaths? I dare say most of us will be in need of further purification in order to enter the gates of heaven after we die, if, please God, we die in a state of grace.
The Catechism of the Catholic Church teaches:
All who die in God’s grace, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven (1030).
I Corinthians 3:11-15 may well be the most straightforward text in all of Sacred Scripture when it comes to Purgatory:
For no other foundation can any one lay than that which is laid, which is Jesus Christ. Now if any one builds on the foundation with gold, silver, precious stones, wood, hay, stubble—each man’s work will become manifest; for the Day will disclose it, because it will be revealed with fire, and the fire will test what sort of work each one has done. If the work which any man has built on the foundation survives, he will receive a reward. If any man’s work is burned up, he will suffer loss, though he himself will be saved, but only as through fire.
No Christian sect I know of even attempts to deny this text speaks of the judgment of God where the works of the faithful will be tested after death. It says our works will go through “fire,” figuratively speaking. In Scripture, “fire” is used metaphorically in two ways: as a purifying agent (Mal. 3:2-3; Matt. 3:11; Mark 9:49); and as that which consumes (Matt. 3:12; 2 Thess. 1:7-8). So it is a fitting symbol here for God’s judgment. Some of the “works” represented are being burned up and some are being purified. These works survive or burn according to their essential “quality” (Gr. hopoiov - of what sort).
What is being referred to cannot be heaven because there are imperfections that need to be “burned up” (see again, Rev. 21:27, Hab. 1:13). It cannot be hell because souls are being saved. So what is it? The Protestant calls it “the Judgment” and we Catholics agree. We Catholics simply specify the part of the judgment of the saved where imperfections are purged as “Purgatory.”
