You will never hear *me* say that the KJV is "above" the original Greek and Hebrew. *I* do not believe that the KJV [ itself ] is "inspired" in the same sense that the original Greek and Hebrew were and are.
But -- for people who speak / read English --
the KVJ is the most accurate English-translated Bible available...
I understand what you are saying - and, can even agree with it - based on your intent ( as I understand it ) for saying it. However, what you must understand is - each case had / has its purpose.
The reason for the Koine Greek is obvious. That was the "common" language of people to speak / read / write. Being Greek - the "full" language that it was - it contained the complete measure - "every nuance" - of meaning that the Greek language was capable of containing.
Nothing was lost in the Greek language. And, this is why the [ original ] NT was written in the Koine Greek.
"God knew what He was doing..."
With English, it is different. The English language cannot contain all of the "nuance" that is in the Greek language. And, the 'Shakespearean Middle English' was the best 'language' to use to "contain the most" of the "nuance" of the scriptures in Greek.
"God knew what He was doing..."
