I would say many (most) Catholics are lost. Mainly because they have a works salvation....confession, communion, their form of baptisim, the sacraments, mass, eucharist....you CAN NOT be saved by works, or it's no longer grace.
IF a Catholic gets saved, I don't believe they'll stay Catholic for much longer. The Holy Spirit will not leave them alone after salvation. I believe some of them are deceived...let me rephrase that, most of them are deceived into believing a false gospel that Paul warns about.
There is NO other English Bible. The King James stands alone. There are many translations that have been done since our beloved KJB, but I prefer to call those perversions...because they pervert the pure Word of God. The Catholic Bible is one of those many perversions. Not only does it take out major doctrine we hold dear, but it adds entire non canonical books...the Appocrypha and that nonsense. And it doesn't have them there soley for historical reasons as the first additions of the King James did.
No wonder the nuns got in a tizy. They don't have the truth and don't know how to respond to someone who does. They've been lied to, and taught that lie all their lives.
I read in one of your posts that you are Baptist in a Catholic school. Be careful. Stand for the truth and don't let their teachings get under your skin. At the worst they are heretics and at the best they are deceived. Hold fast the KJV and it's truths as your sole authority and you should be just fine.
