Well the way I see it is that, everything in any bible is supposed to be the word of god. The Revelation to John as far as my understanding goes is that he was told to write down these revelations by Jesus SON OF GOD and God in three persons as we are taught in our schools.
And besides this, it shouldn't (to my mind) divert from the fact that no matter what bible one decides to read those verses are the same, examples:
I warn everyone who hears the words of the prophecy of this book: if anyone adds to them, God will add to him the plagues described in this book, and if anyone takes away from the words of the book of this prophecy, God will take away his share in the tree of life and in the holy city, which are described in this book. Revelation 22:18-19 (English Standard Version).
I testify unto every man that heareth the words of the prophecy of this book, if any man shall add unto them, God shall add unto him the plagues which are written in this book:and if any man shall take away from the words of the book of this prophecy, God shall take away his part from the tree of life, and out of the holy city, which are written in this book. Revelation 22:18-19 (American Standard Version).
And I solemnly declare to everyone who reads this book: If anyone adds anything to what is written here, God shall add to him the plagues described in this book. And if anyone subtracts any part of these prophecies, God shall take away his share in the Tree of Life, and in the Holy City just described. Revelation 22:18-19 (Living Bible).
I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll. And if anyone takes words away from this scroll of prophecy, God will take away from that person any share in the tree of life and in the Holy City, which are described in this scroll. Revelation 22:18-19 (New International Version).
The bible then it seems is warning against doctoring (tampering with, adding to, and taking away) what is written in the revelation from god via Jesus via a messenger.
I am sure you get my point 4Consideration.
