Why does having a personality with attributes imply that he is changing?
Kosta, you are astounding me tonight with your rejection of the abundantly clear record of Scripture. The things you reject are explicitly stated in Scripture. Your argument is with God, not with us.
Lastly, wasn't it you who accused me of Nestorianism because somehow you construed that I said a nature was crucified not a person? It seems that it was. Perhaps not. But if not, your orthodox brethren might beg to differ with some of your commentary tonight.
The Divine Hypostates (Persons, not personalities) are how God revals Himself to us in the Divine Economy of our salvation. Divine Nature, on the other hand, His essence, is immutable and unchanging. Christian theology 101.
Your argument is with God, not with us
Hardly. My argument is with those who deny that Christ is God as much as the Father and the Spirit are the same God. My argument is with those who suggest that the eternal God is changing, mutable, subject to passions, subject to necessity, etc.
...wasn't it you who accused me of Nestorianism ...
When what you said appeared to be denying dual natures of Christ, yes. And it wasn't only I, but many others who had the same impression.

No doubt, some may, but I would wager that they would recognize their own beliefs in my insistance that God is not subject to passions and mutation. It is rather we, who experience God's love differently depending on our spiritual state. We are the mutable creatures, not God.
