Byblos: As for the rest of the links, I have no interest in debating such topics and even less interest in reading so-called 'sources'.
Well, those "so-called sources" are SCRIPTURE - a very specific and careful examination of what the Catholic Church teaches vs. what Scripture actually says and clearly reveals to be true. I can see why that might be a problem to those whom are determined to only swallow the Catholic Church koolaid! Because once a person has bought into the belief that there is some asserted/authorized descendancy that can not only break new "Scriptural" ground exists, but that can also clearly CONTRADICT established Scripture (which ended in the 1st Century), then NO Scripture in our Bibles will sway them otherwise.
For those of you who REALLY care, I'd advise you to read through the links. Either they will validate and give confidence to one's Catholic beliefs OR they will make them seriously question as to HOW or WHY of key Catholic teachings - particularly concerning Salvation - could actually be true! Are we to believe that men given the authority and inspiration to break new Scriptural teachings were given no absolutely clear and unmistakable mandate in SCRIPTURE???!!! And so unclear is this that a HUGE percentage of Christians - and I'm talking amongst those Scripturally literate - vehemently disagree, due to their comprehensive study of the Scripture that Catholics assert give such authority. Now, how is it that something supposedly so clear, WOULDN'T be to so many Christians around the world who take Scripture and its study extremely seriously? So, what is asserted to be a clear mandate by the Catholic Church, simply isn't so clear. In fact, it's not only not clear, but Scripture's plain wording and reading show the Catholic teaching of its church authority and Popes, to break new Scripture, directly CONTRADICTS Scripture. So, ignore the links, if you don't care/if you've already made up your mind.
And, BTW, what I showed the CC asserts about Salvation is no caricature, but a direct documented teaching by the church - spin it as one will.
