when some scribe added 1 John 5:7, (most likely to "prove" the trinity doctrine which really needs no defense as it is an obvious teaching of the Bible) he "added" to the Bible a verse that shouldn't be there. There are plenty of other verses that prove the Trinity---God doesn't need help from a scribe.
So you bring up the supposed interpolation of 1st John 5:7. As far as can be seen it does not seem to appear before the 1300s actually. The reason this is not an interpolation is because without verse 7 verse 8 makes absolutely no sense. The priest who first compiled the TR originally left it out. When he was asked why he left it out his answer was "show me one Greek MSS that has it and I will put it in." A few years later he was shown an older text that had it and so true to his word he put it back in.
the reason why we can see that this was in the original autograph is because, 6This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
7For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
8And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.
take out verse 7 and the whole statement is here left wanting. Not to mention that the Spirit, water, and blood are gender neuter terms. Yet they are not used as such in verse 8. They make clear reference to verse 7.
So it was not the translators of the AV that "added" this it was found in an older Greek MSS and then placed in the TR after having been shown to the priest(I will get his name for you as soon as I can remember it)who first compiled the TR.
Not because they do not desire to understand it but because in many cases it is VERY HARD TO READ!
I was a High School drop out and I had an AV that I could understand perfectly, this is why I hated reading it, because it convicted me of my sin. If you are reading a book, any book, and you do not understand a word, you look it up in the dictionary. You want to talk about dropping things out of the scriptures look at every single one of the Revised Perversions. They all drop the deity of Christ, they all take out the last half of Mark 16. why do they do that, do you suppose? Every last one of them takes away the last half of Romans 8:1
There is therefore now, no condemnation to them that are in Christ Jesus; who walk not after the flesh, but after the Spirit.
They all drop the stipulation for what being in Christ Jesus is.
And just to help you out a little bit here "thee" means you, "thou" means you, and "ye" is plural for you.
