Please don't think me heretical in this however, this how I see it:
I have noticed that thoe who judge others as heretics are seldom saints themselves ... for myself I am not fit to judge anyone , nor desire to do so, and that judgment would only fall back against me if I did ... so i will discuss you points only as I see the scripture in hope that you realise that iam just a sinner seeking to understand how God's words fit together, I am not asserting anything, just trying to see the implicdations of
all that the words say
Divinity cannot be imperfect , but did not Jesus show us that a man can be perfected in love by means of being given baptism of the spirit [when God finally gives it] and trial of that given faith to perfect the love [baptism of fire , a term used by John the baptist] ... thus showing that man can be perfect before being made immortal by tranmslation to spirit? ... in fact more than that, that there is no other way to immortality of the spirit than to become perfect in love during life ?
and we know Christ laid aside that to indwell the man Jesus. He wasn't yet perfected as Divine-Man, purposed for Him by the Father. Though a "reality" in the Mind iof God from all eternity, there were things yet for the man Jesus to accomplish for that to be an "actuality".
It seems a fair paraphrasing of scripture

... the ultimate reality is the spirit , all spirit is from God whetehr manifesting as good or evil, all thus returns to God who gave it .... the physical relm is thus somewhat irrelevant except that it proves that love works AND that all other possible ways fail ... Jesus' task then is to show that perfection of love in the world, in life as a man, works.... Satan's task is to show that no other way works, taht all his bdevious imaginings and wily temptations lead only remorselessly to death [which then frees men from sin] but not to salvation until men follow Jesus' way of love... by menas of baptism of the spirit [promised to all men eventually -Joel 2:28- and then the precious trial of faith which Jesus and the few saints went through in this life before Jesus' return, but most men do not ... most die sinners and cannot be translated to spirit, so there would be no point in their being resurrected at the first resurrection...
Jesus was God's representation of what He wanted man, from the beginning; Adam, to be; Jesus was normal man, here to show us the Father's Ultiimate Intention for His creation! And deomonstrated by Him was "Self-renunciation": the way of the cross.
Yes, all men will follow Jesus as Lord, he says so... Revelation 5:13 ... and so all craetion is redeemed through jesus christ, but clearly not all can be first ... Jesus says how many are first Rev 7:3-8, and that inumerably many of all nations are saved after this ... but after this implies the second resurrection , thus this salvation is in the righteous new earth kingdom come, and the first few are priests because they serve the many later, and they are kings because they rule the many under jesus as king of kings in his kingdom come, but it is not on this earth that it comes :-
John 18:36 Jesus answered, My kingdom is
not of this world:
Revelation 5:10 And hast made us unto our God kings and priests: and we shall reign
on the earth.
God then comes down to dwell with men in the new earth ,in 'New Jerusalem', where righteousness is the law and is upheld by Jesus with 'rod of iron'
Revelation 21:3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and
he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God.
In His humanity Jesus learned perfection "by the things He suffered". When He satisfied His Father in the tasks and testings presented Him, He ascended to the Mount and was transfigured. That was His "Graduation day"!
That is indeed the precious trial of given fath from God , the baptism of fire taht all men must go through after baptism of the spirit, but it is clear that most men did not get given all truth from God in this life , so men are not all baptised before death [John 16:13] , in fact only the 144,000 are sealed in the spirit in this life [Rev 7:3-4] to be saints now , ceasing to sin because they are so sealed :-
2 Timothy 2:19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
Again it is true that most men die sinners , not saints, most men do not depart from iniquity in this life... but many live righteously in the new earth, not just the few who are saints in this life :-
2 Peter 3:13 Nevertheless we, according to his promise, look for new heavens and a
new earth,
wherein dwelleth righteousness.
His LOVE for the Father; his purposes for Him and for Himself brought Him back down to get us, to redeem us by going to the cross that we might be the righteousness of Christ.
Jesus ahd a short term purpsoe in this earth which he stated , and a longer term purpose to redeem the many in the new earth, which he also stated ... it is starnge really that so many men conflate the two and think that everyone who is saved must be saved in this life ... the scripture nowhere even sugest that, quite the opposite in fact, that the many are saved after the few [Rev 7:9-10], that the few are first only because God chose them from the beginning to be hs priesthood of kings [Exodus 19:6] for this kingdom come in the new earth
We can see by this, that it is not just to redeem us that He went to the cross but, when He uttered the words: "It is Finished", He made possible our salvation and with the new birth, the imputation of the Father's Nature, that we might accomplish our Son-ship as He did. That by the impartation of His Holy Spirit we can now have the Character of the Father perfected in us as He did before His tranfiguration.
Aagain, read John 16:13, and note taht most men die sinners without all truth of God.... redemption is not finished in this earth, only few find the narrow strait way of saints in this life, god never intended otherwise tahn that His kingdom should grow in stages like a tree growing huge but starting from a tiny sed, growing bit by bit ...
Simply see that the many go by the broad way through death freeing them from sin before they are baptised to knwo all truth after resuyrrection, notin this life... the few find the way now, but teh many are saved too, just afterward, not in this life, not by Kesus' return... without perfection by trial in lidfe no-one can be redeemed to spirit, so the many who die sinners must be perfected in the new earth, not now, and their salvation is at judgment day, not at the return of Jesus in this earth when they are just dead sinners, not dead saints... not raedy for translation as the few saints were BEFORE they died ...
