The books mentioned are part of the Apocrypha, books of 'doubtful authenticity' from the Old Testament.There are fourteen altogether I believe.
Catholic Bibles, not protestant bibles, contain the apocryphal books - we don't doubt the books and writings authenticity.
However, when Martin Luther broke from The Church (which was suffering from 'bad' leadership), he made many changes to fit with his views.
If one were to attempt to condense his thesis to a few main points (as we learn in lessons) the points seem to be: (1) not in accepted scripture then not Biblical (our belief in purgatory is a good example). (2) Priesthood of all believers. (3) Salvation through faith, not works. (3) Salvation through grace alone.
Catholics have 7 Biblical sacraments, if I understand correctly many Christain Churches have only 2 sacraments - the other 5 are not in their gospel? Well, as noted our Bible contains more books and other works.
