You absolutely do not believe in the doctrine of preservation, because there is nowhere to find a preserved pure word, it's strictly imaginative in your minds.
You misrepresent and distort the views of believers who accept the preservation of the Scriptures.
Does a consistent application of your own inconsistent or faulty assertion or reasoning maintain that KJV-only advocates absolutely do not believe in the doctrine of preservation since there was nowhere a preserved pure word in the original languages before 1611 that match 100% the KJV or even one today that they can demonstrate matches the KJV 100% without changes being made to the existing preserved original language manuscripts from other sources?
A consistent and true view of preservation would concern the specific original language words given to the prophets and apostles.
A consistent and true view of preservation would be true both before and after 1611.
