Peter and John are distinct persons because they are two totally different men.
Both men of flesh and with different minds and bodies.

But Jesus is the one true God and the Son of God the man Christ and so differences are seen in that you wish to make a YHVH a different person than Jesus nature as God, Jesus becomes "a god" just like your sister religion the Jehovah Witnesses hold, matter of fact, your explaination is so close to them as to be almost word for word what they hold.

Jesus is SPIRIT DEITY IF HE IS GOD, because God is Spirit John 4:24 and John 20:28 and Rev. 21:6-7 clearly show that Isa. 9:6 is fulfilled and Jesus is God.
God is not and doesn't need to be seperate persons to fulfill his word.

The Father is the eternal Spirit deity of which Jesus as , has always been and always will be.
The addition of his human body/tabernacle of flesh came in time and is how he purchased us with HIS blood of God as the Son of God, for God's blood is his own and only came about with the incarnation in the Son.
Zech. 12:10 makes it clear God counts that body as his and yet almost aloof from him when he says..."they shall look upon me whom they have pierced, they shall mourn for him."
Clearly God speaks that the body is his and yet speaks as if it is not in the same passage.
DISTINCTION IS SEEN, it isn't two persons, but two natures of that one person of God, which I proved in my affirmation by scriptures and grammar that God is only one person.

You divide God up so much as to make a polytheistic group of deities, first the God the Father is YHVH an then you have a God who is not YHVH, but a junior demigod, where the third person deity is anybodies guess.

Trinitarians deny that Jesus is the God of the O.T., you cannot even conjure up a name for him.
I showed in previous questions and your answers define two First and lasts, two Kings, two coming ones, two everythings and yet we must add the third person in and I guess he is King , though the Bible doesn’t say such and he is a First and Last as well.

The problem you have is that it is YHVH=LORD that is called LORD AND KING in the O.T. and clearly there is only ’ONE’, LORD the KING and he is Jesus and stated in Rev. 19:16 as the LORD OF LORDS AND KING OF KINGS, means you cannot rightly divide the word of God.

Your two first and lasts is absurd, the context is clear, only one is the first and last, one is not the first and the other the last, the language doesn’t state that in Rev. 22:13 compared to Isa 43:10-11 and 44:6,8.

You need the only true God, Jesus.
