The state of the modern bible is predicted in the Book of Enoch, a book that the catholic church attempted to eliminate, and some nice people in Ethiopia kept it and it reappeared in the 19th century and then more recently the text was found multiply amongst the Dead Sea Scrolls.

Of course the catholic priesthood, who were just roman politicians trying to coopt a revolution that would have seen them with the contemporary equivalent of guillotines, didn't want christians to keep reading the book that said they would hide the truth and twist what remained.
