Without the Authority and Infallibility of the Catholic church given by the Holy Spirit there would be no Bible. If the Catholic church was fallible the the Bible is not worth the paper it is printed on.
Because the Protestant do not have this Authority they can take books(Luther) or add books(LDS) to Holy Scripture
(Note not everything the Catholic Church does is infallible it is only on Faith and Morals that the authority to declare infallible exists)

That depends on your interpretation of “doctrinal infallibility”. One can believe that the construction of the Bible was infallible, and not believe that everything the Catholic church does (doctrinally) is infallible. That certain events throughout history have been divine does not necessarily mean that divine infallibility rests eternally in one group of men.
Personally, I have seen no Biblical justification for the belief that doctrinal infallibility is forever.
