Note 4: The Holy Trinity---these three being one are easily shown in scripture in the verses of 1 Corinthians 12:3-6. Jesus is Lord (verse 3) by the Spirit of God, the same Spirit is also called the Holy Ghost in verse 4. It is the same Lord (verse 5). It is the same God (verse 6). All four verses are in referrence to one church---the body of Jesus Christ. For a more detailed discussion on these three being One, click here.
This is merely someone's interpretation of another verse which has absolutely no relevance to
I John 5:7. It proves nothing.
Also, our Lord Jesus Christ Himself said "our" and "we" in referrrence to the heavenly witnesses---
John 3:11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
This does not prove that Jesus is referring to the Father and the Holy Spirit, nor does it prove that Jesus, the Father and the Holy Spirit are all God.
The apostle John wrote in exactly the same way:
- I John 1:1-4
This is what we proclaim to you: what was from the beginning, what we have heard, what we have seen with our eyes, what we have looked at and our hands have touched (concerning the word of life—
and the life was revealed, and we have seen and testify and announce to you the eternal life that was with the Father and was revealed to us).
What we have seen and heard we announce to you too, so that you may have fellowship with us (and indeed our fellowship is with the Father and with his Son Jesus Christ).
Thus we are writing these things so that our joy may be complete.
There is, therefore, no argument to be made from Jesus' use of the plural in
John 3:11.
