Luther's statement that the Bible is the simplest and clearest of any writing on earth is false, whether in or out of the context of debating the Papal Bull.
No, one must read statements in context, that's how honest evaluations of texts should be performed. I seriously doubt you've actually read the quote you're citing in its context... as you keep cutting-and-pasting the quote with "5. Martin Luther, Luther’s Works..." which is the same format R. Scott Clark used in his blog post here. If you actually did utilize Clark's post, it's all the more obvious yours is an agenda absent of treating contexts fairly. Luther (and Clark) are simply saying the Bible is the final authority which determines the veracity secondary authorities. In that sense, if the Bible is the final authority that judges secondary authorities, it is simpler and clearer able to be judge and jury of lesser authorities. In practice: if one picks up any volume of Christian theology, however old or new, its veracity is determined by whether or not it can be substantiated by the ultimate authority.
Rather than deal with excessive Luther quotes... which... is often the typical method of propagandists, I'll re-post the quote from LW 32 and add some commentary on the Lutheran board.We could open a thread made solely of Luther quotes or other foundational Lutheran quotes explicitly using phrases like "Bible alone", "NT and OT alone", etc. to show how they explicitly defined the phrase.
