When I was a children's Pastor, I ran into this phenomenon a few times in a specific church. I later found out that some other churches were the same way in saying the King James Version is the inspired version and no other is.
In regards to scholastic and intelligence, I never could understand why and how people think this way. There were at least 7 other translations before the King James Version was written.
Furthermore, the KJV is never used in scholastic circles when doing exegetical work (translations and meanings of scripture) simply because there are so many errors in the King James Version. For example, one of the translators was a William Shakespeare fan and he hidden his name in the book of Psalms (Specifically Psalm 46 was an attribute for William Shakespeare's Birthday by adding his last name in the passage by splitting it up. In the ancient hebrew there was not a "Shake" or a "Speare" in this original passage.
Also, the KJV incorrectly used the word Jehovah. There is no Jehovah in the old testamanet in the original language. The names for God in the Hebrew was Elohem, El, Ywh, and Adonai. Jehovah is a hosh posh of german combination of Adonai and YWH so they took it on their own account to go outside the scripture and create a new word.
Also, many translations are incorrect int he KJV.
But some people are so attached to the KJV that they think the Almighty God himself written it (and some really believe that God literally wrote it...not inspired it....but sat down and wrote it)
