The problem with that is that their own Bible, in John 1:1 says that "In the beginning was the Word and the Word was with God and the Word was God" – that the Word of God existed before the scriptures, before words, before humankind. Then in 1:14 it goes on to say that Jesus is the Word. Their own book literally (in every grammatically correct sense of the term) tells them that the book itself is NOT the Word of God.
