My take on the KJV-only movement is that it includes a streak of Anglo-American, English-speaking exceptionalism — “the various reformations happened, Christian believers were finally free from the yoke of papal Rome, and God inspired and protected in a special way English translators, for He knew that England would spread her influence throughout much of the world in a few decades and beyond, and that English would become the principal language of world evangelization as well as colonization”. In other words, English became the fourth sacred language, after Hebrew, Greek, and Latin (with an honorable mention to Aramaic, I suppose), for God’s reformed Christian Church, and the KJV became the next best thing to the original MSS.
