The “temporary submission” view claims that the Son’s submission to the Father was only for the period of his incarnation and not before time eternal. The concept of eternal has been discussed in this thread already. Now there is plenty passages of Scripture indicate that prior to creation the Son was eternally subject to the planning and authority of the Father with regard to our salvation.
The Father's planning and authority
Ephesians 1:9-11 he (the Father) made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, to be put into effect when the times reach their fulfillment—to bring unity to all things in heaven and on earth under Christ. In him we were also chosen, having been predestined according to the plan of him (the Father) who works out everything in conformity with the purpose of his will,
Follow up verses of the Son's subjection:
1 Corinthians 15:27-28 For he “has put everything under his feet.” Now when it says that “everything” has been put under him, it is clear that this does not include God himself (the Father), who put everything under Christ. When he has done this, then the Son himself will be made subject to him (the Father) who put everything under him, so that God may be all in all.
Ephesians 4:6 one God and Father of all, who is over all and through all and in all.
This planning and authority of the Father is before time eternal:
2 Timothy 1:9 He has saved us and called us to a holy life—not because of anything we have done but because of his own purpose and grace. The grace was given us in Christ before the beginning of time,
(πρὸ χρόνων αἰωνίων or "before time eternal").
This planning and authority of the Father is an eternal purpose:
Ephesians 3:9-11 and to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things. His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, according to his (the Father) eternal purpose that he (the Father) accomplished in Christ Jesus our Lord.
This planning and authority of the Father is before the creation:
Ephesians 1:3-5 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. For he (the Father) chose us in him (the Son) before the creation of the world to be holy and blameless in his sight. In love he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will—
Follow up verses of the Son's subjection:
1 Peter 1:19-20 but with the precious blood of Christ, a lamb without blemish or defect. He (the Son) was chosen before the creation of the world, but was revealed in these last times for your sake.
Romans 8:29 For those God foreknew he [the Father] also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters.
Revelations 13:8 All inhabitants of the earth will worship the beast—all whose names have not been written in the Lamb’s book of life, the Lamb who was slain from the creation of the world.
The Son was already in subjection to the Father's planning and authority eternally, before time and before creation. Read above Scriptures. Which brings us to my one example about creation mention in OP of this thread. To put the Father's planning and authority into action (which the Son was already in subjection to eternally), then you need a creation. From my OP:
The Scriptures says that "without him" there would be no creation and no subordination. So, the eternal subordination of the Son is done "for him" and his functional role is "for us and for our salvation."
Here is a basic subordinate framework:
From the Father and through the Son
1 Corinthians 8:6 yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
John 1:3 Through him all things were made; without him nothing was made that has been made.
Colossians 1:16 For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him.
Hebrews 2:10 In bringing many sons and daughters to glory, it was fitting that God, for whom and through whom everything exists, should make the pioneer of their salvation perfect through what he suffered.
Romans 11:36 For from him and through him and for him are all things. To him be the glory forever! Amen.
