Georgia, actually, doctrine matters. Just take a look at the New Testament.
Not saying it doesn't....just saying that Protestants and Catholics have much more in common than we have apart. I happen to believe in once saved, always saved...but also don't think that absolves one of taking responsibility for their actions. I think that someone who "loses their salvation" never had it in the first place. That's one difference in believer's baptism and infant baptism. There is a conscious choice made to accept Christ at an age where one knows that they are a sinner and apart from God except through Christ.
I'm not trying to impugn Catholicism. Just giving my point of view as a Protestant...that being said, we are all children of God. Not meaning to offend anyone.
