Actually, Calvinism rests upon all the communicable and incommunicable attributes of God, not elevating one above the other.
Saying it doesn't make it so AMR.
Your founding father (Augustine) flatly and repeatedly stated his unconditional allegiance to the absolute immutability of God. He refused to even become a Christian until it was explained to him how the Bible could be interpreted figuratively so that God's immutability could be retained and proceeded to build his entire theological worldview around that single attribute and the others which Aristotle logically derived from it. Calvinism is nothing but reformed Augustinian theology and Augustinian theology is based entirely on the Greek (i.e. Platonist) concept of deity.
I suspect, Clete, that you might misunderstand immutability and all the associated implications on the attributes of God.
I understand the doctrine completely and I also understand how the TULIP doctines (for example) follow logically from it.
A God that is immutable is unchangeable. Yet if God can change, then it means God aquires something He did not have prior to this change.
This is not what change means. There are many things which change all the time without acquiring anything they didn't already have but I'm not even going to press that point at this time. As far as I'm concerned you just cut your own theological head off.
Did God always have a physical body with hands and feet and eye balls and nose hairs?
Did God always have scares from having been killed on a Roman cross?
Has God always had a new and ever lasting glorified body which retains those scares?
Has God always been a man (i.e. a human)?
Had God always had the experience of being dead?
Is God still experiencing death right now?
Is there anything in the entire gospel story that is not all about God acquiring all sorts of things that He had never had before?
This would mean God would be better, more complete, from this new acquisition. Therefore, God was not previously perfect for He must have lacked some perfection since He changed. Is the God of open theism is not an already perfect God, or is the God of 2007 much more perfect than the God of 6,000 B.C.?
This is also fallacious reasoning.
A change is not necessarily for the better or for the worse. Many changes can be made which are qualitatively neutral and if it is in the nature of a thing to change (i.e. any animate thing such as a clock or a relational person) then immutability would be considered a flaw.
A point which Augustine, Luther and Calvin entirely ignored. I have a difficult time believing that it was not intentional.
A God that is immutable must always exist, for whatever is not immutable can potentially cease to exist. Is the God of open theism subject to non-existence?
How does it follow necessarily that something which is mutable can potentially cease to exist?
Show me the syllogism - if you can.
A God that is immutable is unified in simplicity, for an absolutely simple being cannot be more than one. To be more than one means that a being is composed of parts, but an absolutely simple being has no composition of parts. Absolutely simple beings cannot be divided. An immutable God is an absolutely simple being, indivisible, and cannot be more than one being. Therefore there is only one God.
Do you not believe that in God, unity and plurality are both equally ultimate concepts?
If not, how do you solve the problem of the one and the many?
If so, how does what you said above not conflict with that presupposition?
Yet a God that can change is not composed of absolute simplicity. A God that changes is comprised of what changes and what do not change. In fact, if every part of a non-simple being changes then an entirely new being exists. Can the God of open theism to be relied upon since this God is always changing, even possibly becoming an entirely different God?
God's character does not change. That is to say that those things which make God who He is (His
qualitative attributes), do not change.
