Furthermore, it places great power in the hands of the person who has apparently been enlightened, above all others, to the point where he, and it appears he alone, is qualified to make such a momentous decision” (Hooper, It Is Written, p. 58).
Matthew Vogan wrote: "The Authorised Version stands alone as the translation in the English language that follows the providentially preserved text in its entirety" (Hooper, It is Written, p. 171). This statement by Matthew Vogan could be considered KJV-only, and Vogan's statement is not true.
Douglas W. B. Somerset wrote: "The main use of the Vulgate for the Old Testament is in the translation of difficult words and passages. For example, in Psalm 22:16, the Authorised Version and most other English translations follow the Septuagint and Vulgate in translating the Hebrew word as 'they pierced' rather than 'like a lion'" (Hooper, It Is Written, p. 255). This statement by Douglas Somerset would conflict with Matthew Vogan's claim that the KJV "follows the providentially preserved text in its entirety."
