God the Father beheld Jesus the Christ become the Sin Bearer, and as such, God cannot have fellowship with Him, and turned away and abandon Jesus to experiencing what all lost sinners will when judged for their sins!
Much of what you wrote is all talk and no Scripture.
1) God doesn't have to judge. Non-believers are already condemned. At the last judgement, there are no appeals, but a review of life in the books and a search to see if the name is written in the book of life. No name written, that person is already condemned to the Lake of Fire. When God and judgement are paired in the Scriptures, it is generally stated as having already been determined, not in a manner of some future decision to be made.
2) Believers are individually to stand before the judgement seat of Christ (
2 Corinthians 5) in which they are not judged concerning salvation but their works and motives are judged for validity.
3) It is nonsense that God cannot have contact with sinners. He does all the time both look upon and deal with sinners. One cannot be saved without such contact.
4) There is no Scripture support for God not being able to have fellowship with Christ as the Sin Bearer. In fact, Revelation 5 presentation would certainly refute that thinking.
5) If (not that I agree but to pretend) "turned away and abandon Jesus to experiencing what all lost sinner will when judged for their sins" statement is true (and it is not - for the reformed simply do not endorse that thinking by aligning all atonement benefits only believers) then it would follow a universal atonement presentation and not what you hold.
Note to the readers:
I do support the Scripture statements that the BLOOD of the Redeemer was shed for all sin of all creation. Sin became a non-issue in the reconciliation between God and Man. That is what the Scriptures teach.
However, the Scriptures are very specific concerning the death and resurrection of Christ benefiting ONLY the believers.
This is supported in various places such as this from Colossians 2:
8See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
9For in him the whole fullness of deity dwells bodily, 10and you have been filled in him, who is the head of all rule and authority. 11In him also
you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ,
12having been
buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead.
13And you, who were dead in your trespasses and the uncircumcision of your flesh,
God made alive together with him, having forgiven us all our trespasses, 14by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. 15He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him.
See how the blood is not mentioned in relationship to believers, but the death and resurrection are certainly to their benefit and not the benefit of the unbeliever?
On a side thought:
The question must be asked, did the apostle think of only earthly rulers and authorities being put to open shame and being conquered?
My opinion, the answer is No. For we don't wrestle against flesh and blood, but against those satanic forces which were put "to open shame" and Christ triumphed over them.
