Martin Luther's Words Against the Book of Revelation
About this book of the Revelation of John…I miss more than one thing in this book, and it makes me consider it to be neither apostolic nor prophetic…I can in no way detect that the Holy Spirit produced it. Moreover he seems to me to be going much too far when he commends his own book so highly-indeed, more than any of the other sacred books do, though they are much more important-and threatens that if anyone takes away anything from it, God will take away from him, etc.
Again, they are supposed to be blessed who keep what is written in this book; and yet no one knows what that is, to say nothing of keeping it. This is just the same as if we did not have the book at all. And there are many far better books available for us to keep…My spirit cannot accommodate itself to this book. For me this is reason enough not to think highly of it: Christ is neither taught nor known in it” (Luther, M. Preface to the Revelation of St. John, 1522).
