Big Finn--In the 200th post on this thread, you equate self-exaltation with sin. That is certainly true concerning creatures, because ALL glory BELONGS to God. The earth is full not of the creature's glory, but of God's glory.
Anything in the creature which is considered glorious is from God. He looked upon His creation--"And God saw everything that He had made and, behold, it was very good."
Therefore, any self-exaltation by His creatures is an attempt to rob God of the glory which rightfully belongs to Him as having created it so.
I don't know where you get the idea of self-exaltation on God's part. He does not exalt Himself for He is from everlasting to everlasting infinitely glorious. If He could at any point exalt Himself, it would be a contradiction of His immutability. If He could exalt Himself to any degree, it would be to a glory which He did not have before.
Some Calvinist may have mistakenly used that term, but it is certainly not scriptural, nor is it true to Calvinistic theology.
God's first purpose to get glory to Himself is not self-exaltation, but a determination to make His name known upon the earth--to manifest that glory which is rightfully His, and the highest end of man is to realize God's glory and to fully enjoy Him in that glory. So no one can charge God with being either self-centered, or with attempting to exalt Himself.
You say that the selflessness of Christ shows a contradictory nature between Him and the Father--concerning that, you must realize the Jesus came as a servant to fulfill the mission given Him by the Father.
He was both God and man: two natures in one person, His humanity never becoming partially God, nor His Deity (in Him dwelt ALL THE FULLNESS of the Godhead) in anyway partially human. His purpose on earth was to manifest the glory of God, and in all His ways He did that so perfectly that He could say, "He that has seen me has seen the Father"; that is, as I am, so the Father is. He is just like me. If you want to know what the Father is like, just look at me. The writer of Hebrews said that Christ is the Father's express image.
As Jesus prepared to return to thee Father, He said, "glorify me with the glory which I had with thee before the world was." So there is no way in which the Son and Father are less than One.
