Here is what Jack Hyles said in his book "Enemies of Soul Winning:"
"The words of God are the genes of regeneration. Titus 3:5, 'Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost.' Actually the word 'regeneration' means 'to be re-gened.' Just as the genes of my parents brought my old nature into existence, even so the genes of God brought my new nature into existence. Your old nature is sinful because there was sin in the genes, but the genes of the Word of God are incorruptible, meaning that which is born of God; that is, the new nature, cannot sin. Now if the very words of God must be pure, and if in fact the King James Bible contains the preserved words of God, then any other words are not the words of God. ... we must have the incorruptible seed in order to be re-gened, or regenerated, or born again. Suppose corruptible seed is used. Can a person then be born again from it? You answer that question. According to I Peter 1:23 we read, 'Being born again, not of corruptible seed ...' Then , if corruptible seed is used, one cannot be born again. I have a conviction as deep as my soul that every English-speaking person who has ever been born again was born of incorruptible seed; that is, the King James Bible. Does that mean that if someone goes soul winning and takes a false Bible that the person who receives Christ is not saved? I believe with all of my soul that the incorruptible seed must have been used somewhere in that person's life. If all a person has ever read is the Revised Standard Version, he cannot be born again, because corruptible seed is used, and I Peter 1:23 is very plain to tell us that a person cannot be born again of corruptible seed, but of incorruptible seed, and it explains that that incorruptible seed is the Word of God, and it explains that it liveth and abideth forever. ..."
Here it appears that Hyles, like some others, left some "wiggle room." In theory, if the soul-winner leads someone to pray the "sinner's prayer" using the Revised Standard Version, that person may be saved if they had previously read the KJV or had it read to them - otherwise, they are definitely not saved.
I totally disagree with this statement by Jack Hyles. I don't know if there are still any "lunatics" who still hold to this teaching. Hyles supporters and KJVO people are welcome to chime in and tell us that they disavow this teaching, as Twisted has just done - which is commendable.
As recently as 2013, this extremist teaching by Hyles was being circulated via the article "False Bibles: An Enemy of Soul Winning" which was printed in the Flaming Torch, July-Sept. 2013 issue. (The Flaming Torch is now under a new editor and management, so the current management of that paper may not necessarily still agree with Hyles' extreme teaching on the subject).
