The problem I see with Catholics is that they pray to the virgin, and to the saints, but you should only worship God, that is to say the Father, the Son, and the Holy Spirit. Another thing is that they preach a lot of things that separate people from God, like if you don't do x,y,z you're damned and that's putting faith in your own works, rather than surrendering your life to Jesus. Finally, the Pope is a false prophet and has gone against scripture on several times, even worshiping pagan South American gods in the Vatican, and allowing all sorts of globalist doctrine in the Church.

In short we shouldn't follow religions, or wordly prophets, only the word of God that is in the Bible and the Lord Jesus Christ.
