There's one fact that stops KJVO dead. It cannot be refuted.
That fact is KJVO'S TOTAL LACK OF SCRIPTURAL SUPPORT. Without Scriptural support, no doctrine of faith/worship can be true, & KJVO doesn't have one quark of it!
Saying Psalm 12:6-7 are "proof-texts" for KJVO is wrong. First, those verses are about PEOPLE, as the footnote for the 2nd "them" in V7 in the AV 1611 shows. That note reads, "Heb. him,
I. Euery one of them.
Besides that, WHERE do those verses mention the KJV or any other translation?
Why Christians wanna believe a false doctrine that has no Scriptural support is beyond me !
