GOD argued with Abraham and offered to change HIS Mind about Sodom and Gomorrah so some change is NOT outside of HIS immutability. For the Son to be immutable and yet become human it only means that becoming human was within HIS nature from the git go and NOT a change, probably because humanness contains the image of GOD.
THIS IS NOT THE DOCTRINE OF IMMUTABILITY!!!!
This is not even Christianity!
God was not always human! God did not always have a physical body!
There was a time BEFORE God had ever grown inside of womb (or outside of a womb). There was a time before God had ever been hungry, or eaten, or had His belly full of home cooked food, or slept, or wept, or a thousand other things associated with being a human being. He most certainly had never been dead before and by extention had never been resurrected before!
Not only that but there are lots and lots of times throughout the scripture where God changes His mind. In fact, there's one whole book of the bible devoted to telling the story of one such incident!
Jonah 3:10 Then God saw their works, that they turned from their evil way; and God repented from the disaster that He had said He would bring upon them, and He did not do it.
---------------------
For that which is changed does not retain its own being; and that which can be changed, although it be not actually changed, is able not to be that which it had been; and hence that which not only is not changed, but also cannot at all be changed, alone falls most truly, without difficulty or hesitation, under the category of being. - Augustine - God’s Existence and Essence - Book V Chapter 2
"That which is accidental commonly implies that it can be lost by some change of the thing to which it is an accident. For although some accidents are said to be inseparable, which in Greek are called 7χ8ριστα, as the color black is to the feather of a raven; yet the feather loses that color, not indeed so long as it is a feather, but because the feather is not always. Wherefore the matter itself is changeable; and whenever that animal or that feather ceases to be, and the whole of that body is changed and turned into earth, it loses certainly that color also. Although the kind of accident which is called separable may likewise be lost, not by separation, but by change; as, for instance, blackness is called a separable accident to the hair of men, because hair continuing to be hair can grow white; yet, if carefully considered, it is sufficiently apparent, that it is not as if anything departed by separation away from the head when it grows white, as though blackness departed thence and went somewhere and whiteness came in its place, but that the quality of color there is turned and changed. Therefore there is nothing accidental in God, because there is nothing changeable or that may be lost. But if you choose to call that also accidental, which, although it may not be lost, yet can be decreased or increased, – as, for instance, the life of the soul: for as long as it is a soul, so long it lives, and because the soul is always, it always lives; but because it lives more when it is wise, and less when it is foolish, here, too, some change comes to pass, not such that life is absent, as wisdom is absent to the foolish, but such that it is less; – nothing of this kind, either, happens to God, because He remains altogether unchangeable." - Augustine - God’s Existence and Essence - Chapter 4
That crap is hard to follow but what he is saying that it isn't just "in His essense" that God is unchangeable. It's BOTH in essense and accident that God "remains altogether unchangeable". (The word 'accident' is used in the philosphical sense of the term. It refers to any attribute that may or may not belong to a subject,
without affecting its essence -
source).
And before you tell me that Augustine wasn't a Calvinist - Calvinists are Augustinians, reformed Augustinians to be sure but it wasn't this portion of his doctrine that they rejected. On the contrary, they not only acknowledge it, they fully embrace it and defend it with nashing teeth!
First, God is immutable in His essence. His nature and being are infinite, and so, subject to no mutations. There never was a time when He was not; there never will come a time when He shall cease to be. God has neither evolved, grown, nor improved. All that He is today, He has ever been, and ever will be....
...He cannot change for the better, for He is already perfect; and being perfect, He cannot change for the worse. Altogether unaffected by anything outside Himself, improvement or deterioration is impossible. He is perpetually the same. He is altogether uninfluenced by the flight of time. There is no wrinkle upon the brow of eternity. Therefore His power can never diminish nor His glory ever fade.
Secondly, God is immutable in His attributes. Whatever the attributes of God were before the universe was called into existence, they are precisely the same now, and will remain so forever. Necessarily so; for they are the very perfections, the essential qualities of His being. Semper idem (always the same) is written across every one of them. His power is unabated, His wisdom undiminished, His holiness unsullied. The attributes of God can no more change than Deity can cease to be. - A.W. Pink
Notice that Pink not only equates immutability with divinity itself but that he uses
Plato's argument for immutability virtually verbatim...
Socrates: “It is universally true, then, that that which is in the best state by nature or art or both admits least alteration by something else.”
Adeimantus: “So it seems.”
Socrates: “But God, surely, and everything that belongs to God is in every way in the best possible state.” “Of course.” “From this point of view, then, it would be least of all likely that there would be many forms in God.”
Adeimantus: “Least indeed.”
Socrates: “But would he transform and alter himself?”
Adeimantus: “Obviously,” he said, “if he is altered.”
Socrates: “Then does he change himself for the better and to something fairer, or for the worse and to something uglier than himself?”
Adeimantus: “It must necessarily,” said he, “be for the worse if he is changed. For we surely will not say that God is deficient in either beauty or excellence.”
Socrates: “Most rightly spoken,” said I. “And if that were his condition, do you think, Adeimantus, that any one god or man would of his own will worsen himself in any way?”
Adeimantus: “Impossible,” he replied.
Socrates: “It is impossible then,” said I, “even for a god to wish to alter himself, but, as it appears, each of them being the fairest and best possible abides for ever simply in his own form.”
Adeimantus: “An absolutely necessary conclusion to my thinking."
Plato, Republic, Book 2
