I need to clarify here. I do not mean a “separation of the Trinity”. I grant that you do not believe that Christ ceased being God. That said, I do view the idea as an internal inconstancy within the members of the Trinity.
Part of our disagreement may be in my rejection of covenants within the Trinity. So there is the hazard that misunderstandings may arise simply by the language we use to describe our views. If possible, I will try to avoid this by asking for clarification of you and striving to be very clear in my own responses.
Thank you. I think that will be very helpful in our discussions. I see a 'Covenant of Redemption' or 'Covenant of Grace' among the Persons (better, I think, than 'members') of the Trinity as being vital to the understanding of our salvation. Here's an extract from one of my blog posts:
'References to the Covenant of Grace can be found in various parts of the Bible if one is prepared to look for them as the following examples will show:-
Luke 22:22
. “And truly the Son of Man goes as it has been determined……” Determined where and by whom if not in the Covenant of Grace?
John 6:38-39
. “For I have come down from heaven, not to do My own will, but the will of Him who sent Me. This is the will of the Father who sent Me, that of all He has given Me I should lose nothing, but should raise it up at the last day.” Christ has been given a people and the task by the Father which He is determined to fulfil. What can this refer to if not the Covenant of Grace?
John 10:16.
“And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd.” Not, “I
will bring,” but, “I
must bring.” Our Lord had been given a commission to fulfil.
John 10:17-18.
“Therefore My Father loves Me, because I lay down My life that I may take it again. No one takes it from Me, but I lay it down of Myself. I have power to lay it down, and I have power to take it again. This command I have received from My Father.” Where did Christ receive this command, the doing of which merited so well the Father’s love? In the Covenant of Grace, of course.
Phil 2:6-8.
‘Who, being in the form of God, did not consider equality with God something to be held onto, but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross.’ In the Covenant of Grace, our Lord gave up temporarily that equality with the Father that had existed from all eternity, and became the willing servant of Exodus 21:5-6 and Psalm 40:6-8 in order to rescue those who had been given to Him (John 17:2, 6 ).
Heb 2:13.
‘Here am I and the children whom God has given to Me.’ Given by the Father to the Son in the Covenant of Grace to be redeemed from sin and brought to heaven.
In Isaiah 42:6, Christ is described as the Covenant itself. He is, in His own Person and work, the very substance of it. In Mal 3:1, He is,
‘The Messenger of the Covenant’because He came to proclaim it and make it known. In Heb 7:22, He is,
‘The Surety of a better covenant.’ Christ came as the representative of fallen Man, being engaged to fulfil the obligations incurred under the Covenant of Works. In Heb 9:15, He is,
‘The Mediator of the New Covenant’ since He has brought about legal satisfaction between God and man so that covenantal blessings are now imparted to those who had previously forfeited them, and He now stands between the two parties, advocating the cause of man to God (1 John 2:1 ) and speaking a word of the comfort of God to the weary man (Isaiah 50:4 ). I am indebted to A. W. Pink for much of the forgoing; let us now hear from him direct.
‘But how could Christ sustain such offices a these unless the covenant had been made with him (Gal 3:17)
and the execution of it had been undertaken by Him (Heb 10:5-7 )
? [Heb 13:20]
is quite sufficient to establish the fact that an organic connection existed between the Covenant of Grace and the sacrifice of Christ. In response to Christ’s execution of its terms, the Father now says to Him, “By the blood of Thy covenant I have set forth Thy prisoners [those given to Him before the foundation of the world, but in Adam fallen under condemnation] out of the pit wherein is no water” (Zech 9:11 ).’

What you describe is unity. I agree with you here. This, as I understand it, is unity between the members of the Trinity. Could we describe this as roles (i.e., a unity between Father, Son, and Spirit in their roles for accomplishing redemption)?
That said, what I still see is a disharmony – not between Father and Son (I do see it there, but that’s not my main concern) but between the Son and God (as One).
How can a person look at Christ on the Cross and say “there is the fullness of God”? It seems they could only say “there is the Son” and “there is the Father”. But it seems to me that Scripture teaches when we see the Son we see the Father, and when we behold the Son be behold the fullness of God in the flesh.
Does my question make sense to you?
First of all, let's admit that these are deep waters. Augustine wrote:
"I will be attempting to say things that cannot altogether be said as they are thought by man-- or at least as they are thought by me. In any case, when we think about God the Trinity we are aware that our thoughts are quite inadequate to their object, and incapable of grasping Him as He is....." [Augustine,
The Trinity, bk.5, 1].
Rather than ' look at Christ on the Cross and say “there is the fullness of God,”' I think we need to be saying, "There is Christ who is fully God." The Triune God does not hang upon the cross; Christ does, and that applies whether one accepts Penal Substitution or not. But is the One hanging on the cross fully God? Yes! Is He gladly and willingly carrying out the Father's will? Yes! Does He hate sin in just the same way that the Triune God does? Yes! Will He send unrepentant sinners to eternal punishment? Yes (Matthew 25:41)! Why? Because they have
'trampled the Son of God underfoot, counted the blood of the covenant by which He [Christ]
was sanctified a common thing and insulted the Spirit of grace' (Hebrews 10:29).
I hope that helps. I may not quite have grasped your concerns, but no doubt you will clarify if that is the case. But maybe we should follow the advice of Charles Wesley:
''Tis mystery all! The Immortal dies!
Who can explore His strange design?
In vain the first-born seraph tries
To sound the depths of love divine.
'Tis mercy all! Let earth adore,
Let angel minds inquire no more.'
