Man has not to do a crusade to burn every other bible which is not a KJV, because no one preaching recalls all the exacts words of God therefore everyone would pollute them. Also apostles repeated verses of the Old Testament with some changings, but changings can be of two kinds: 1) the ones who doesn't pervert the doctrine and the spirit and 2) the ones which, under the alibi of the impossibility to repeat everything 100% exactly, are purposely changing/perverting doctrine & spirit. God knows when you repeat his commands with some mistakes about His original words but your heart is sincere, and knows when someone is changing the spirit of the God's words with the alibi that "no one can recall all perfectly".
It is clear that every other Bible not-KJV has to be compare with the KJV as final authority, and the author of this pages explains that to you very well:
"...The kinds of errors outlined in this and the previous post reveal more than just the usual mistakes that are made in any translation. They reveal a cavalier attitude toward the doctrine of VERBAL inspiration. The NIV is not interested in translating the WORDS of God, but the CONCEPTS of God. Yet such cannot be done apart from the words. I would remind anyone interested in the truth, that Paul based an important aspect of the "seed theology" on the fact that the word occurred in the SINGULAR and NOT the PLURAL form. If even singulars and plurals are important to a correct understanding of God's word, how dare we take such an attitude toward it that we will translate "idea by idea" rather than word by word?"
Edited: notice the punctualization of the author. The NIV focusing on the CONCEPTS betray that it is built on the HUMAN REASON, of which the "concepts" are the raw material, the food to make grow rationality like a wild plant which (in the plans of Satans code-named "Gnosticism") had to suffocate the plant of the faith. Doc Martin Luther who was more Catholic than what it ever appeared, said well when he affirmed that "the reason is the prostitute of Satan".
