I think you hit it on the dot. Those were my thoughts as well. Being raised catholic, we were taught that it was through faith AND through good works that we gained salvation. I wouldn't say it's anti-biblical, though. Good deeds done by Catholics is a practice done to emulate the good that Jesus did and by doing so is spreading the goodness of God through action. A life of service was seen as a noble thing to do. I agree with this still, even though I'm not Catholic. To do good things to benefit the less fortunate or to benefit more people than yourself is always a good thing, whether you're religious or not. I don't think many people would argue about whether helping the homeless is a good thing or not. Catholics may emphasize it, but works are not the main factor in terms of finding salvation -- BUT it is the defining factor that differentiates Protestant from Catholic in terms of practice. HOWEVER I'm not rejecting the christian pursuit and value it as well. To have faith in something is a great thing, and to base the belief that faith will lead to salvation is itself a noble pursuit aswell.
I'm not saying that good works have no place....but according to scripture, good works do not earn you salvation. It's by grace alone. Good works should be a natural outgrowth of your faith, not an attempt to get on GOD's good side. Also the whole confessing to priests thing. Not found in scripture. Praying to the saints, including mary; not found in scripture. Trans substantiation: not found in scripture. There's more...but you get the picture. 90% of it isn't so much taught by the Christ they claim to follow as much as it is dogmas that man created to seem more pious.
Another big difference, as you mentioned, are the texts. Both are called the Bible and are taken from the same source, or at least similar sources, but interperetation is different. As well as additional texts. Catholicism of the modern day has been defined by various theologic philosophers and thinkers throughout the ages who have shaped the religion into what it is through their views on faith and God. an example of this would be Dante's "The Divine Comedy", where the modern day concept of Hell is based. I could also discuss, the saints; Acquinas, Francis of assisi, but then I'd be going on and on and on
Dante's divine comedy is fabricated out of speculation and is not found in scripture. Some dudes were on point. The ones who were came from a time before statue worship and/or had a lot of problems with the condition of the catholic church. This is why we eventually had the reformation.
Also, we really do not have the same bible as far as I know...for example, the Maccabees. Not in the protestant bible. Esdras. Not in the bible. 2nd Daniel. I forget the others...but you get the point.
I could go on and on but I'm not a big fan of the concept of a Pope either. I especially have criticisms of the current one. The previous, Pope John Paul II was an intensely wise and loving man in my eyes, though. Had he not been the pope he would probably still affect global change in some way. He never let his title make his head swell, unlike Ratzinger.
Pope=not deity=fallible and so his OPINION should not be put on the same level as scripture.
I just think your convictions in your faith are strong. You had no intention of bashing catholicism, but I feel as if you misunderstand Catholics. They're good people with strong faith... I just personally don't agree with the faith which is why I'm no longer catholic, lol.
My convictions ARE strong. I believe my misunderstanding of Catholicism stems from my ignorance to the fact that there must be a ton of different versions of Catholicism that I was unaware of. I'm only going off what I've been told. Sometimes my language may seem strong and condemning when in reality I'm just stating fact. The sky is blue, water's wet, the bible says this, and such beliefs don't fit. I know that there are many good people who are catholic...many good muslims too...bhuddists...atheists...etc...by man's standards, I've met a ton of good people with strong belief in their religions...It's no bash on them. I'm just stating what I believe...and it so happens to offend even if that's not my intention.
