I actually don't have a huge problem with the Catholic Church..not like some people do. I don't think the Pope is the antichrist, and I don't think just because someone is Catholic then they can't possibly be a Christian. Catholic doctrine today is far less heretical...when the reformation happened the Catholic Church was forced to look into it's own doctrine and revise it...for the benefit of everyone, I think.
I know many people who are Catholics who are genuine, lovely Christians.
I think my two biggest problems with the RCC is the doctrine of purgatory and the Pope. Purgatory, in my opinion, teaches a Jesus plus doctrine. It teaches that people can 'work off sin' in that place. Sin is either, in it's entirety, placed on us or on Jesus. If it's on us, we go to hell, if it's on Jesus, we go to heaven. Simple, and what the bible teaches.
The Pope may indeed be a very good man. Moral, caring, all of that. But as Foreigner said, when he took the position of Pope he was putting himself behind a position that is not biblical. I have no problems with Church leaders, and I most certainly think that leaders need to be shepherded and under authority as well, but that authority should not be one man who is seen to be the ultimate 'mouthpiece' of God.
But, as a general rule, I don't feel the need to spray the Pope, what he does or does not will be dealt by God. I do worry that many Catholics who are not strong in knowledge of scripture will tend to put him on a pedestal of worship that he should not be on, and I don't know that the Catholic Church discourages that as it should.
I would also say, that if you felt ashamed by your ignorance, well and good...that is entirely up to you, the Spirit and what He convicts you of. But you cannot assume that everyone else is making judgements from the same place of ignorance...in fact, it's kind of the same thing...your making judgements based on ignorance, because you simply cannot know what others already understand. If you are making a general comment of warning based on your own experiences, then perhaps it would be best to leave out phrases like "wind bags" and "simpletons".
