- I don't believe in praying to saints. There is only one mediator and that is Jesus Christ. (1 Timothy 2:5)
- Out of every catholic church I had been to in my lifetime, I had yet to attend one where the learning process was interactive (i.e. bibles at each chair for others to follow along). Ofcourse, this is purely a matter of taste.
- The priest is viewed as holy and above the rest of the church, as is the pope. Yet, we must refer to Romans 3:23 to understand that even he is a sinner, so we should not treat him any differently than we would a fellow church member.
- Idolatry is abundant in the catholic church. Ofcourse, it isn't fair to say that every catholic is an idolator, but it is seen much more often in catholocism than in the baptist denomination (although I'm not baptist, my church is non-denominational). Mostly we see this happen with statues of saints, Jesus, and the Virgin Mary.
- It is catholic belief that Mary was pure and sinless. This is why she is often put right next to Jesus in level of importance. As offensive as this may seem to many catholics, she was not pure...but she was the most suitable candidate to conceive our great messaiah. (Romans 3:23)
- Baptism must be include an understanding and acceptance of the faith. Catholics baptize at birth, then allow the children to understand through catechism (I would know, I went through most of it). If we take notice of Mark 16:16, we read "He that believeth and is baptized shall be saved; but he that believeth not shall be damned." Never does it state it in the reverse.
- In the catholic church, during communion, wine is given to those who take the communion. Yet, Numbers 6:3 and Proverbs 23:31 affirm that we should not drink fermented wine, but fruit of the vine, a.k.a grape juice. I never liked that idea as a child, and the truth behind that act was revealed to me in becoming a born again Christian.
- Finally, the catholic church emphasizes strongly on works in order to be saved. 2 Timothy 1:9 clearly states that it is not by works but by grace that we are saved. That is not to say that we are not obligated to do works in the Lord's name for His glorification, but it is to say that our works don't determine our salvation, only our understanding and acceptance of His sacrifice for us on the cross can do that.
