What do you mean by "interpolation," Tim?
I was referring to the opinion of the scholars I mentioned in my response that the wording in the cited verse after the word "record" had not been part of the original inspired text but had been inserted by an unknown source at a later time. ("Interpolation" = the insertion of something of a different nature into something else)
So you would go along with this that follows? "”RSV scholars say that this verse is an interpolation, a concoction, a fabrication.”
Among the thousands of careful English translations available, the King James translation is the only one which includes this ending to 1 John 5:7—”For there are three that bear record in heaven, the Father, the Word and the Holy Ghost, and these three are one.”
It is abundantly clear that the King James translation made a serious mistake here, for this passage is found in no original Greek manuscript before the sixteenth century. Its inclusion probably resulted from a scribe inadvertently incorporating a marginal comment (gloss) into the text as he copied the manuscript."
The wording that you quote in your comment appears to agree with the opinion of the scholars that I mentioned in my response. I do not view this dispute as in any way compromising the inspiration of the original text, or of any other portions of the Bible.
I agree wholeheartedly with you, Tim.
