But don't ignore the verses that I quoted that said that Jesus came down from heaven when he became human, and that he was in heaven before he was made human, that he was with God before the world was made, existing in the "form of God".
I don't think that is correct. Paul wrote that "
all things" were created through (by) Jesus, even the thrones, etc.. The 'thrones, dominions, principalities and powers' existed before Jesus' ministry. They had been visibly on the earth for thousands of years, and if they had been created "through" Jesus then Jesus must have existed before he became human. Hebrews 1:1-2 (WEB):
(1) God, having in the past spoken to the fathers through the prophets at many times and in various ways,
(2) has at the end of these days spoken to us by his Son, whom he appointed heir of all things, through whom also he made the worlds.
or as other translations put it, e.g. TLV:
(2) In these last days He has spoken to us through a Son, whom He appointed heir of all things and through whom He created the universe.
The Greek word (
aion) that is translated as "worlds" or "universe" could be translated as "ages" - a period of time - in which case if the ages were made through Jesus then once again Jesus must have existed before he became human.
1 Corinthians 8:6 (WEB):
(6) yet to us there is one God, the Father, of whom are all things, and we for him; and one Lord, Jesus Christ, through whom are all things, and we live through him.
Ephesians 3:9 (WEB):
(9) and to make all men see what is the administration of the mystery which for ages has been hidden in God, who created all things through Jesus Christ;
When speaking about Jesus Paul wrote, Hebrews 1:8-13 (WEB):
(8) But of the Son he says, “Your throne, O God, is forever and ever. The scepter of uprightness is the scepter of your Kingdom.
(9) You have loved righteousness, and hated iniquity; therefore God, your God, has anointed you with the oil of gladness above your fellows.”
(10) And, “You, Lord, in the beginning, laid the foundation of the earth. The heavens are the works of your hands.
(11) They will perish, but you continue. They all will grow old like a garment does.
(12) You will roll them up like a mantle, and they will be changed; but you are the same. Your years will not fail.”
(13) But which of the angels has he told at any time, “Sit at my right hand, until I make your enemies the footstool of your feet?”
And in a message from Jesus, Revelation 3:14 (ESV):
(14) “And to the angel of the church in Laodicea write: ‘The words of the Amen, the faithful and true witness, the beginning of God's creation.
ISV:
(14) "To the messenger of the church in Laodicea, write: 'The Amen, the witness who is faithful and true, the originator of God's creation,
YLT:
(14) 'And to the messenger of the assembly of the Laodiceans write: These things saith the Amen, the witness—the faithful and true—the chief of the creation of God;
But Paul wrote "all things", not just certain positions of authority in the Church. What are these "thrones, lordships, governments and authorities" that are needed for the Church? We are all equal in Christ, and we have just one head, one Lord - Jesus.
Galatians 3:26-28 (WEB):
(26) For you are all children of God, through faith in Christ Jesus.
(27) For as many of you as were baptized into Christ have put on Christ.
(28) There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus.
