This is my opinion...
And to make a point...
When I was struggling with the concept of the Trinity, I searched high and low for a long time, prayed, etc. And in God's mercy, HE showed and revealed Truth to me. BUT, I realized for every person that one talks to, one will get a different view on the Trinity, a different view, a different explanation, a different illustration, etc. etc...some radical some conservative, etc.
And it hit me one day...and this is what I believe...if the Trinity view exults Jesus, Who was, is and is to come, then I am for it, but if the Trinity view does not exult Jesus, then I am against it.
In the same way...
When I look at Bibles, I find that the most important overview of the Bible is the exultation of Jesus...if it plays down Jesus, Who was, is and is to come, then I am against it.
So, when I look at modern Bibles, I find that some of them do alter the words. For example, removing the word "Name" and replacing it here and there with "authority", knowing full well, that in the Thayer's definition, that "authority" is a minor alternate meaning for that Greek word. Now, we see that word "authority" in John 5:43, 10:25, and even in Acts 2:38!!! And "Name" is a basic Greek word meaning Name. Authority is like a secondary alternate meaning.
Also, probably one of the most obvious verses is John 1:18. That word "bosom" which in the Greek is bay or between the arms, etc. But what do we see now in sooooo many translations? "Side".
Since when does Bosom become side?
In Revelations, the Lamb is in the midst of the Throne!
Oh, but people will say, oh, Jesus sat down on the Right Hand of God. True, it says that, but it means "in the place of authority". Now, why don't they translate that? Instead, they even double it in some places where it says "right hand" where in the Greek it only says "right".
But that is not in all cases.
When I see deliberate deletions from for example John 3:13, it makes me wonder about people trying so hard to invent another doctrine, when it is all so unnecessary.
So, what am I trying to say in all this?
That we can pick and pick at all the discrepancies that we find in the King James Bible or the other Modern Translations,... but what is all important? It is about Jesus, God Who came to die, shed His Blood and save us and forgive us and so many things. God did not send someone else, but it was God Himself, in a Human Body.
In that regard, don't you think that the KJVO's have a case? I think they do. For there are many, many places where it is clear Who Jesus was on earth in Human form.
But I also believe that a couple of other Bibles have a case too.
Yet, we all see the problems made by human hands.
So, what can be done? Guard the treasure and pass it on to your children. I mean really, guard the treasure.
