What exactly does “Rome” teach that denies Catholics salvation?
Here’s a start:
If anyone says that by faith alone the sinner is justified, so as to mean that nothing else is required to cooperate in order to obtain the grace of justification let him be anathema (Trent, sess. 6, canon 9).
If anyone says that the righteousness received is not preserved and also not increased before God by good works, but that those works are merely the fruits and signs of justification obtained, but not a cause of its increase, let him be anathema (Trent, sess. 6, canon 24).
Don’t forget the Mary idolotry:
From Pope John Paul II’s will:
“Watch, therefore, for you do not know on what day your Lord is coming” (Mt 24: 42) - these words remind me of the last call that will come at whatever time the Lord desires. I want to follow Him and I want all that is part of my earthly life to prepare me for this moment. I do not know when it will come but I place this moment, like all other things, in the hands of the Mother of my Master: Totus Tuus. In these same motherly hands I leave everything and Everyone with whom my life and my vocation have brought me into contact. In these Hands I above all leave the Church, and also my Nation and all humankind.
He places his moment of death, the church, his nation, ans all mankind into the hands of Mary?!
The whole Catholic system is “another gospel, which is not another.” (Galatians 1:6-7)
