I’m going to go out on a limb here (hah) and say that this is going to be very, very controversial…oh well!
There are several things that I want to say, but the first is this. Not all Catholics are non-Christians. This post is simply things that I believe are wrong with the Catholic Church in general. Okay, here we go.
The first thing is the pope. There is no need for a pope, seriously. Catholics (and most people in general) treat the pope as if he is some special. His very title (your holiness) treats him with an unBiblical air. The Bible is very clear. No one is righteous. Even the pope. To claim otherwise is blasphemy, period. No one is holy except God. End of discussion.
The next thing is the whole “you can earn your salvation” junk. That, also, is unBiblical. This is also very clear. Ephesians 2:8-9: “For it is by grace that you have been saved, through faith-and this not from yourselves, it is the gift of God-not by works, so that no one can boast.” Okay. End of discussion. Well, not really. There is also Purgatory. This is pretty much the same thing. Once you die, you go to Purgatory, where you work off your sins. Obviously, this is also unBiblical, for the same reasons (not even to mention that Purgatory isn’t ever mention in the Bible).
Something else (this is the one that kills me the most, figuratively speaking) is that Catholics pray to Mary (and the other saints). First of all this is absolutely unBiblical, period, end of discussion. Christ instructs us to pray only to God, and He will hear our prayers through Jesus Christ. There is one mediator between man and God. One. ONE.
So, that is about it. There’s more I could go into, but that’s enough to prove that Catholicism (which wasn’t actually establish by the apostles. The Church meaning the organized gathering of Christians (not the Catholic Church alone) was set up by the apostles.) is very, very off on a lot of extremely important things.
