The Rambam writes [Tumas Tzaraas 16-10] that Miriam equated Moshe to other נביאים [and therefore was critical of him for separating from his wife].
The Rambam also says that the seventh עיקר of עיקרי האמונה is to believe that Moshe was greater than all other נביאים.
So was Miraim כופרת in the seventh עיקר??
