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.
your orthodox brethren might beg to differ with some of your commentary tonight
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.
I look at God as HE reveals HIMSELF in Scripture. Not on how some churchmen have defined him. When one looks at Scripture, one does see God as an angry God. He declares such. I'm not going to argue with Him.
