Some theologians say subordination may be understood in terms Jesus' function or role as Saviour, but not in terms of his being as God the Son, that's how I would understand it.
My right hand can be subordinate to my left hand, but they are equal hands, in their being. My hands can be subordinate to my brain, but all are my body. My brain might be greater than my hands, in some way, but their being is the same.
Of course, Jesus is not only some impersonal part of something. Jesus is a Person . . . of love >
"God is love" (in 1 John 4:8&16). And Jesus is
"the image of God" > 2 Corinthians 4:4 > an image of gold can have nothing but gold in it, plus there is gold elsewhere than in that image.
What matters is not only what label we put on Jesus, but how Jesus is and how Jesus loves. We are commanded to become like Jesus and to love like Jesus has loved >
"And walk in love, as Christ also has loved us and given Himself for us, an offering and a sacrifice to God for a sweet-smelling aroma." (Ephesians 5:2)
So, while we may be busy with whether or not to call Jesus "God", we need to make sure we are following His example.
Pharaoh granted Joseph his Vizier complete authority over Egypt... because, ultimately, that authority was Pharaoh's to wield as he saw fit
But both were human in their being, though there were differences in who was greater in this or that.
So, yes there have been ways in which our Father has given to Jesus, but this does not automatically mean They are different in Their spiritual being.
I think of how Jesus has said >
"'For as the Father raises the dead and gives life to them, even so the Son gives life to whom He will. For the Father judges no one, but has committed all judgment to the Son, that all should honor the Son just as they honor the Father. He who does not honor the Son does not honor the Father who sent Him.'" (John 5:21-23)
So, if God wants us to honor Jesus
"just as" we honor our Heavenly Father . . . this can show that Jesus is God . . . as the Son.
God sent His own Son, in His love for us. If we truly love, we give our own selves and not less. We love God, by giving ourselves to Him (2 Corinthians 8:5) > so, I can see, God loved us by giving His own Self > His own Son, Jesus. He did not send some lesser or second-best being ministering some second-best blessing.
"'And the glory which You gave Me I have given them, that they may be one just as We are one: I in them, and You in Me; that they may be made perfect in one, and that the world may know that You have sent Me, and have loved them as You have loved Me.'" (John 17:22-23)
So, God loves us by giving us His very own
"glory". And Jesus God's Son has claimed in this prayer how our Father loves us even as He loves Jesus. So, this is how sharing God is, as
"love". And this is our example to follow > Ephesians 5:1-2, 1 John 4:17.
So, there is more to this than who gets which label.
I would say that correct theology will bring us to more and more share with God, in His own love and glory and this changing us to be and love like Jesus.
Another thing > about if the Holy Spirit is God >
"Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us." (Romans 5:5)
So, from this I think we can believe that the Holy Spirit is the Spirit of God's own love. And my opinion is that no one but God can be the Spirit of His own love.
And Jesus refers to the Holy Spirit as
"another Helper", in John 14:16. So, after Jesus had been here on earth, the Holy Spirit was going to be sent . . . as
"another Helper", which I understand means Jesus was a Helper and the Holy Spirit then would be
"another". Therefore > if the Holy Spirit is God, and
"another Helper" after Jesus was a Helper, I can see this means Jesus is equal to the Holy Spirit who is a Person of God.
