Sola fide, sola scriptura, deprecation of Mary, rejection of Holy Eucharist, dismantling of the Old Testament, etc.
"Deprecation of Mary" - what is that supposed to mean, and how does the KJV (presumably apart from other versions) do that? By not elevating Mary to an Isis-like status as "the queen of heaven"? By showing that she needed a Saviour (Luke 1:47) like anyone else, and hence, was not herself "immaculately conceived"? By giving no depiction whatsoever of any "assumption" of Mary into heaven?
I've got news for you - the reason the KJV doesn't teach any of those is because the Greek manuscriptual tradition, as well as every other ancient language version doesn't. The assumption of Mary, her immaculate conception, her status as Queen of Heaven - those are all Catholic dogmas invented at a far later date which have nothing whatsoever to do with Biblical Christian faith.
More on the others later, if I have the time.
