So... when you say "add to salvation requirements", how do you get that? Where did you get your "list of requirements", and how do you know that you have the right list?
Luther translated all of those books, put them in an appendix nad had a similar view of them as many other Catholic scholars. (Some who were deemed Saints BTW> Is EENS still Catholic dogma, is the requirement to be subject to the Roman pontiff in order to be saved still Catholic teaching?
