Printing presses not only deliver the information that is stored inside of them, but they also remain a conduit for additional information. They have to become a known source for the delivery of information that is accurate, trustworthy, and beyond reproach.
A printing press has no capacity to change the information that it contains. It merely delivers, with unabashed tolerance as to the nature of the information being communicated. A printing press that has the ability to change the information contained within it would be considered defective. So too is a messenger of God who dares to amend the message. The Lord God Almighty is a God of truth. The Lord God Almighty is true.
