At "real" seminaries, the history of the development of the Bible is taught.
I don't use the KJV because I find that there are too many archiac words not in use today and it distracts from my understanding of a passage. I don't mind the "thys and thous. I mostly use the New King James version.
When I do research, I use the internet. I go to BibleGateway.com and look at several versions, always including the King James.
Whaa? This topic is getting stranger and stranger!! Seems like the Bible was codified in the 390s and "development" shoulda stopped by and at that time. And what exactly is "the history of the development of the Bible" anyway?
