The Bible teaches that we are justified by grace alone, through faith alone, because of Christ alone. The Catholic religion does not accept this. Catholicism adds human righteousness to the requirements, including that we must:
The Bible says that Christ is the only way of salvation. Biblical Protestant convictions have always been that no sinner can be saved apart from the saving work of Christ granted to him through faith. Christ’s word, “No one comes to the Father except through Me,” means that those only who are united to Christ will be saved; all others will die in their sins and suffer the wrath of God in hell forever.
The Catholic church teaches that only through faith in Christ plus Catholic baptism is salvation granted. There are exceptions; e.g., in the cases of martyrs for the faith (Catechism 1258), and infants dying without baptism (Catechism 1261).
The Second Vatican Council’s Decree on Ecumenism states:
Furthermore, Catholicism teaches that all mankind, whether they come to faith in Christ or not, if they have a desire to please God and to be right with Him, though ignorant of Jesus Christ, can be saved! Hosts of Protestants and many adherents of all other religions, may be saved because they receive the benefits of Catholic baptism through their ignorance and desire!
This doctrine called “Rapprochement” makes Catholicism a kind of universal religion, placing all religions to some degree under its umbrella. All people are thus capable of being saved, even in their unbelief (see Catechism 1257-1261).
God’s Word says:
See: Will all mankind eventually be saved? Answer
See: Am I good enough to go to Heaven? The true answer: No you’re not.
