I'm a little late for this party although I will give my 2 cents in on at least Col 1:15-18. I agree with your OP...
I can add nearly the same commentary..
In
verse 15: the image of God speaks volumes and certainly that an image surely cannot be God himself. The Son of man reflected perfectly, as the perfect completed image of his Father.
The 'first born' here refers to Jesus specifically after his resurrection from the dead by his Father. And of all creatures does mean
all creatures of all time and the future. It relates to
Christ being the firstborn to the new eternal life and 'all' the 'new' creatures of believers are those that follow(ed) him, the Father's elect.
Verse 16 is not about the creation act depicted in Genesis by God Almighty. Trinitarians and other who believe Yahshua pre-existed, make the error of suggesting that Paul is speaking of Genesis and creation of ‘all things.’ and this time by Jesus. This is a verse they claim says that Jesus is the creator of ‘all.’
‘All’ or the Greek transliteration ‘pas’ here, has an association and a definite limitation of scope and a limited context. It is related to Christ and the scope of what his Father gave him authority to create since his ascension. These things created in heaven and earth are such things as angels governance and order with their dedicated service to Christ’s body, and the nurture of new believers in the Spirit. As you pointed out..
The structure of verse 16 is conveyed as a beginning statement and a restatement of it at the end to ensure the reader understands the context or meaning is read in between them. (Beginning) In him 'all' things were created… things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities….’all’ (THESE things as a list are stated) things were created through him (End). So between ‘them’ spells out what this creation means, and it does not mean the creation of ‘all things’ as in Genesis. It is limited in scope and cannot mean ALL the universe etc. That exotic meaning would be way out of context.
In the beginning of Genesis 1 and now here what I call 'Genesis 2' as the new creation in his Son, God created the world and all things with a certain outcome in mind and with
his word and spirit - the means by which to bring about salvation for mankind, so in this sense all things and the world were made with Jesus in mind, and through him. The things spoken of in this verse however are for the development and maturing of Kingdom in his Body or his church. As you also indicated..
Paul has certain expressions he used quite frequently. One is the expression “in him” as in “in Christ” or “in Jesus.”
The context and setting for verse 16, begins before it as in most cases of scripture.
The error in translation of the verse is critical.
(Col 1:16) For in him (by his Father’s word – my addition) were all things created, in the heavens and upon the earth, things visible and things invisible, whether thrones or dominions or principalities or powers. All things have been created on account of him and for him (by his Father’s word – my addition) . (NEV)
For through the Son (by his Father’s word – my addition) everything was created, both in the heavenly realm and on the earth, all that is seen and all that is unseen. Every seat of power, realm of government, principality, and authority—it was all created through him (by his Father’s word – my addition) and for his purpose! (TPT)
Many translations of Col 1:16 incorrectly read ‘ For by him…’ as if to say that Jesus himself actually created these things instead of his Father by his word and spirit. And then they go off context completely and extend this creation of the Son to old Genesis, and say he created the heavens and the earth. I guess I made this point already.
Everything pertinent to this world runs through Jesus Christ because his Father desires it and created it all. His mission given by his Father is to establish and grow the Kingdom of his Father. To tear down all powers and authorities, and to destroy evil and eliminate death completely. When completed, Jesus shall return the Kingdom of his Father, representing the full restoration of creation to his Father so his Father can dwell in or be in ‘all’ creation.
Verses 13 and 14 speaks to the Kingdom given to Jesus who was raises to immortality.
In him we have redemption.
Verse 15 is about the new creation the Kingdom of God given to the head,
the first risen. He is the head of all believers - the
whole of creation.
And of verse 17, Christ is indeed before 'all' these same (the same limited scope) things, again he is in charge of all these things he created by him for the church's life. There is no mention of a Genesis creation here. And why should there be mention of it? It would stick out like a sore thumb indeed!
And again, in
verse 17, Paul uses the same “in him” expression to mean “for him” he was ‘before’ or the first in rank and in preeminent, and from all believers within his body.
Verse 18 provides more context that the subject is all about Jesus in heaven. It reiterates the fact that Jesus is and
became first, the firstborn of any dead human being. And also, Jesus should have pre-eminent in all things, of the Kingdom.
God, his Father does not need to have pre-eminence of anything or to anyone. He already has it!. He gave authority to Jesus, and he then would require him being first in all things or the pre-eminent one in, or of all things in this Kingdom and in the heavens and on the earth. And he does have this as he sits in power at the right hand of his Father, in heaven.
In Christ and for Christ, God the Father brought all the new creation back to order. He uses Christ to fix creation on the earth, and in the heavens, both with the creation of believers of the Kingdom.
In verse 18b it explains more clearly verse 15b, that Christ is the beginning, not of Genesis because we are drawn to the word 'beginning,' He is the beginning, or even the father of the new life (cf.
Isaiah 9:6 - everlasting father) and firstborn from the dead, indeed.
...end it now as it may well become a rant .....
