That is not a picture of the holy spirit IN heaven. In context the full idea:
1Pe 1:11 searching what, or what manner of time, the Spirit of Christ who was in them was indicating when He testified beforehand the sufferings of Christ and the glories that would follow.
1Pe 1:12 To them it was revealed that, not to themselves, but to us they were ministering the things which now have been reported to you through those who have preached the gospel to you by the Holy Spirit sent from heaven—things which angels desire to look into.
It's the spirit of christ, the holy spirit that God gives us as a gift. Notice how it's synonomous with Christ. It's not a different "person" in a Godhead but a portion of God's spirit that lives in us.
The rest of your scriptures mention the holy spirit but specify no membership in the Godhead. They're understood as what they are....the interaction of God with humans.
How would you explain the lack of the holy spirit co-existent and co-eternal here:
Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
Joh 1:2 He was in the beginning with God.
Joh 1:3 All things were made through Him, and without Him nothing was made that was made.
This is a clear picture of the Godhead. The divinity and personhood of Christ and the father are clearly stated and expressed. Was it a colossal oversight of John NOT to mention the supposedly co-equal, co-eternal 3rd "person" in the Godhead? What is your explanation?
I see you keep using the term 'Holy Spirit'. Since ONLY GOD is Holy, are inferring there is a binary God and another god named 'Holy Spirit'? Think long and hard before you respond. The term 'Holy' should not be used for any but HE Who IS Holy. The term is misused often, referring to men of different denominations and all different religions. They are not Holy in the same meaning of Holy Spirit. So, is The Holy Spirit another god, or does the Holy Spirit issue from The One God? Think man, THINK!
In Ref. to boatbums post:
“I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. He shall glorify me: for he shall receive of mine, and shall shew it unto you. All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew it unto you. (John 16:7-15)”
Ask her why the pronoun “he” isn’t capitalized, as it is when used to refer to Christ?
That verse DID say the Holy Spirit was "sent FROM heaven", did it not? If He was sent from heaven, He must have been IN heaven. As for the Holy Spirit being part of creation, you can turn to the beginning as told in Genesis:
You linked the United Church of God websites and I see that on one of the major doctrines of the historical Christian faith, your denomination is:
Would it be correct to say you don't believe that Jesus is the incarnation of Almighty God but a separate "god" from the Father? Because if so, we have far more disagreements than just the deity of the Holy Spirit.
