It would be pretty shakey ground IF the Johannine Comma(1 John 5:7) was in fact a later addition. I think it would do some good for people to really study the whole point that this was an addition.
The people who originated this claim about the Johannine Comma being an addition were of the modern translation movement. Most all of them attribute this addition to Erasmus who was one of the responsible parties for putting together the KJV.
So this would mean the Johannine Comma would have popped up somewhere around 1590-1610AD.
Problem with this?
Well in [SIZE=-1]200AD[/SIZE] [SIZE=-1]Tertullian quoted the verse in his "Apology Against Praxeas".
Also in 250AD [/SIZE][SIZE=-1]Cyprian of Carthage, wrote, "And again, of the Father, Son, and Holy Ghost it is written: "And the three are One" in his On the Lapsed, On the Novatians.
If you were to look in a Waldensian or Vaudois Bible, you'd also see the Johannine Comma there as well. The interesting thing here is, that this would date us all the way back to 157AD.
So if we maintain the most popular belief concerning Erasmus or any KJV affiliate adding the Johannine Comma, we have to either erase history, or pretty much find a way to make time travel possible as Erasmus would have had to travel back in time 1400 or so years and put the Johannine Comma in history.
Do some studying on the Vaudois vs the Roman Catholic Church. You'll find somewhere in the reading that the Vaudois faught for some 1400 or so years to preserve the bible they had, received from Antioch of Syria in 120AD. They died for their bibles, trying to keep it in tact. However modern days, Roman Catholic Church has succeeded in their mission.
I'm not attempting to show prejudice, just facts. If anyone here is Catholic and offended by this, I'm sorry, I'm simply stating clear history. Research it for yourself if you don't want to take my word for it
Anyways, for this reason and many others, I detest new age translations, and so the Johannine Comma (1 John 5:7) is more than enough proof of the "Trinity" for me.
[/SIZE][SIZE=-1]Dr. S. Franklin Rogers, the co creator of the NASV for instance has gone on to say: [/SIZE]"I must, under God, renounce every attachment to the New American Standard Version". But thats another topic really, something else however it's worth researching. God bless you. [SIZE=-1]
Edit:
[/SIZE][SIZE=-1]I forgot to address the Isaac Newton thing. [/SIZE]He argued<sup id="cite_ref-4" class="reference">
</sup>that the Johannine Comma was first taken into a Greek text in 1515 by Cardinal Ximenes on the strength of a late Greek manuscript corrected from the Latin. Finally, Newton considered the sense and context of the verse, concluding that removing the interpolation makes "the sense plain and natural, and the argument full and strong; but if you insert the testimony of 'the Three in Heaven' you interrupt and spoil it."<sup id="cite_ref-5" class="reference">

So Newton would have as well had to explain how Cardinal Ximenes traveled back to 120 or so AD to corrupt the Vaudois Bible.
