And why do these men get so agitated when when we refer to the "King James Version," rather than calling it the "King James Bible?"
It may be a result or by-product of their human KJV-only reasoning or exclusive only claims for the KJV.
Some KJV-only advocates often do not even refer to the KJV as a version or as a translation as they may use only the name King James Bible for it, and they may suggest that only the KJV should be called the Bible.
KJV-only author Troy Clark asserted: “I will never call inspired Scripture a ‘version’” (Perfect Bible, p. 30). After referring to the King James Bible, Jim Ellis declared: “I don’t call it the King James Version” (Only Two Bibles, p. 17). D. A. Waite asserted: “I call the King James Bible the Bible” (Foes of the KJB, p. 44), but he also admitted: “The King James Bible is a translation” (p. 46). In a personal word in William Grady’s book Final Authority, Jack Hyles maintained that “the King James is not A version, but THE Bible” (p. iii).
D. A. Waite claimed: “The New King James Version is not a Bible, but a version” (Central Seminary Refuted, p. 19), showing KJV-only inconsistency.
