Well, you start off making a claim, "The Protestants understand that the RCC teaches a "work-gospel" that can not save and the Catholic church thinks that Protestants teach a "greasy - grace" gospel that requires nothing more than a simple confession of wrong doing/sin due to the emotional preaching of a man."
Something which stands out is that you claim Protestants "understand" but the Catholic church "thinks", when referring to what is believed by others. Anyone who thinks they understand that the Catholic Church teaches a work-gospel is incorrect. The Catholic Church also does not think that Protests teach a "greasy-grace" gospel. (Some Catholics may but the Catholic Church doesn't claim this. Another thing is to try to assume that there is a Protestant Doctrine. There are many churches which consider themselves Protestants and each has their own unique beliefs regarding Christianity.
You assume, "that every Catholic believer will agree that when it comes down to deciding a theological issue about defined Catholic dogma, there isn’t anything to discuss on the Catholic's side because once Rome speaks, it is settled." Boy, you haven't heard Catholics debate about doctrine.
Then you say "Whenever there is a theological discussion when trying to debate a Roman Catholic – reason and Scripture are not the Catholic’s final authority; they can always retreat into the “safe zone” of Roman Catholic Authority." Again, you must not have discussed very many topics with Catholics because very few fall into this concept. Most good Catholic debaters are more than happy to go toe to toe with scripture.
Now, I am not here to debate my Protestant brethren on what each believes because my main focus is if God has accepted them by baptizing them in his Holy Spirit. If God accepts them, so do I, regardless of what they may teach.
God Bless
