I commend you for your effort.
when we learn to rightly divide the word of truth, we find out that God the Father alone is "the God". We learn that God the Father is spirit, not flesh, thus we must worship him in spirit and in truth, for the flesh profits nothing. God is holy and God is spirit, John 4:24 ,therefore God calls himself "the Holy Spirit" for that is what he is, he is holy and he is spirit.
God gave to us of his spirit, it is now our spirit, I John 4:13.
Since we have God's spirit in us, we can fellowship with God as sons. We are no longer body and soul, but with the addition of God's spirit in us, we are now body and soul and spirit.
I John 1:3 tells us that this epistle was written that we might have fellowship with the believers and with the Father and with his son Jesus Christ. Why is "the Holy Spirit" not part of this fellowship?
Because "the Holy Spirit" is simply another one of the scores of names that God calls himself by, it is not another being or person.
When we rightly divide the word of truth, truth being the Greek word "logos", when we rightly divide the logos of truth, we find that God is spirit, He choose to send a son to cause him to be conceived divinely so as for our redemption and salvation.
The son obeyed the Father, because the son is inferior, derived and subordinate to the Father.
Hence, I commend you for your effort, but that verse no more teaches a trinity than does
Matthew 17:1
And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart,
or Job 1:8
8 And the Lord said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?
or Matthew 1:18
Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
