The Emphatic Diaglott has a footnote
"This text concerning the heavenly witnesses {as found in some versions} is NOT contained in ANY Greek manuscript which was written earlier than the 15th century. It is not cited by ANY of the Greek ecclesiastical writers; nor by ANY of the early Latin fathers..."
The Holy Bible - New Catholic Version: "For there are three that bear witness {in heaven: the Father, the Word, and the Holy Spirit; and these three are one. And there are three that bear witness on earth}: the Spirit, and the water, and the blood; and these three are one."
The brackets are supplied by the translators. This version also has a footnote:
"According to the evidence of many manuscripts, and the majority of commentators, these verses should read: ‘For there are three that bear witness: the Spirit, and the water, and the blood; and these three are one.’ The Holy See reserves to itself the right to pass finally on the origin of the present reading."
The New Testament from 26 Translations: Footnote, page 1183:
"The words between ‘bear record’ (verse 7) and ‘the spirit’ (verse 8) are now recognized as not adequately supported by original manuscripts."
As those words were hand written in a copy of a manuscript as late as the 15th century and do not appear in ANY Greek manuscript, they have no place in the inspired Word of God. I know of only one other verse that is not supported by original manuscripts, and that is Acts 28, verse 30. This added verse in Acts 28 is not, however, as harmful as the added verse in I John 5:7.
"I and the Father, We are ONE" (John 10:30).
Let me be perfectly clear, logical, and Scriptural on this matter:
One plus one plus one DOES NOT equal one!
One God plus one God plus one God DOES NOT equal one God!
One third of a God plus one third of a God plus one third of a God DOES NOT equal one whole God!
The Holy Spirit of God cannot also be that same God! ANYTHING that is either "from" or "of" something ELSE cannot also "BE" that something else no matter what or who it is!
