Martin Luther axed the Deuterocanonicals without the benefit of the guidance of the early Church.
He did it because it contradicted certain theological points that he personally disagreed with.
He didn't "ax" them, he moved them to an appendix. He actually did have the guidance of the early Church since they didn't officially affirm them either until after Luther did what he did. Luther treated them exactly the same as many early leaders on your side, like St. Jerome. There was nothing new in what Luther did. Besides, there must be a reason why the Deuterocanicals are DIFFERENT from the "Protocanonicals". :)
