Yeah see, that's just it.
It's amazing to me to hear people try to justify OSAS. They counter their claims by saying, "Well wait, you Catholics say yourself that you sin every day, so isn't that the pot calling the kettle black?"
What they won't admit to, in person, nor on these forums, is that the belief that once you're saved, always saved is nothing more than a good excuse for them to do whatever they want, and they don't have to necessarily do anything, nor try to get closer and closer to God. They're saved, and life is good. If they continue to sin, and they don't need to strive not to, then, well, that's just our imperfections coming out -- God knows our hearts.
However, the anti-OSAS crew knows that this battle is a continous battle against Satan. We must continously work on not sinning. And through God's grace, he will work with us on those things that are the major issues in our life.
Maybe it's cursing, or vulgarity, or whatever -- the Lord will work with you in your life and make you stronger. As you grow stronger in God, you sin less.
I can tell you right now that as I do the little things, like penance, and Hail Mary's, and holding that door open for a person who has their hands full of coffee at
Peets, or wherever, that these are the things that have made me a stronger Christian. I'm drawing closer to God as I try to think that maybe I shouldn't cut that person off in front of me (patience) or maybe I should allow that person who do wants to cut me off, have my space anyway (graciousness)...
If I don't do those things, am I sinning? I think that if we KNOW to do good and we don't, then it's a direct disobedience towards God, which is a sin.
When we continously strive to get closer to Him, by identifying our faults, then we are making active strides in NOT sinning, and thus, we become closer to Him, we lead more peaceful lives, and Christ looks favorably upon us.
OSAS, on the other hand, breeds laziness. You don't need to strive to not sin, because, well, it's just too hard...and besides, I'm assured my salvation -- it's like welfare abusers. Why work when the government is sending you the chedda?
The reason why people will debate you until the cows come home is because they know in their hearts that the anti-OSAS crew is right. They are feeling convicted, and they don't like to hear that.
OSAS gives you this false hope and assurance that all is good and you're going to heaven.
The Bible says that we can't serve two masters.
Sorry for getting on a tangent...
