Thanks to Juan Manuel Ferrera we now know that:
Even in relatively “young” religions like Christianity, tampering with sacred words of prophets carry severe reactions.
18. For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:
19. And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.”
These are the very last words of the Bible.
