In the history of Christendom we see many churches which started of as so called cults or so called heretic movements, though many years later they sometimes outgrew their original group and/or became one of the many main churches. Therefore one should be very careful by damning a group or calling ti a cult or sect, when there is not really anything what qualifies it to become called a sect or cult.
We may not forget that language is always changing and that written language fossilizes it and makes it stop changing. The Bible, especially the King James Version, has been very influential on keeping language the same because it has been so widely read, but even there we must be aware that certain words have changed and that today certain phrases in spoken as well as written English may be brought differently than the 1611 version. King James Version people are people who work against the Will of God, not willing to recognise that today we may have people with more and better knowledge of God's Holy Word than those of the 17th century. By not willing to accept the advancement which is made in Bible archaeology KJV-only people become adversaries of God.
