So here we have it in your own words......The RCC is the final authority.<quoted text>
Jesus Christs One True (Universal)
Church which has is and will always be the Catholic Church is the "final authority". If the bible is the final authority of TRUTH than which one of your 42,000 different interpretations of the bible is the (final authority of TRUTH). God is NOT the author of your "bible only" contradicting and conflicting Protestant confusion and chaos!!!
So you would trust your eternal life to an instution which has led in the inquisition and the sex cover up and the buying and selling of indulgances and has chosen to be the leader of the RCC some of the most evil and vile men in history? You would place you faith in this institution ans the "final authority" above the infallible, inerrent word of the Living God? God help you.
