Here again, from the Eastern Orthodox P.O.V., Jesus had to have the "co-operation" of His human "side"/"nature" to accomplish everything. Thus, Jesus was "synergistic"...
Not sure about the use of the term, or even how the Eastern Orthodox view of this subject. It was a clear choice of God to use the situation to redeem His creation. His nativity as a human reconciled humans, and not any other creature, including animals and angels.
Man took upon Himself the EGO, the Fallen Nature, and the accompanying term, "flesh." In some ways "flesh" is used to describe the blood, meat and bones of humans and animals. Also, God uses it to describe the natural state of fallen man and the current default status of Human Nature. The actual human blood, flesh and bones of man are not the cause of his fallen status before God. However, in that state, there is no place for Him except in this temporal life.
For promises of glory with God to be realized by anyone in human flesh, God must change their physical bodies. The idea that we may be ushered into God's presence as a human requires the change of the nature of the person before the change in the nature of the body. Those not made into a new creation by God, are to be cast away, and share in the torment of Hell and the Lake of Fire with the fallen angels (for whom these were created.) Their bodies will be changed to be able to continue throughout eternity in the torments they have chosen when rejecting Christ as their LORD and Savior.
That God was in Christ and that God existed as a human required that He be subject to the limitations of mortal flesh and blood. I am amazed at all the iterations of ideas used to somehow diminish this, and eventually, they seem to tie back into the false idea of the physical frailty being equivalent to the LORD being subject to giving-in to temptation of the devil. This was proven to be wrong when Jesus Christ endured 40 days of fasting, and THEN was tempted with things none of us can imagine or endure.
At the weakest point in the physical existence of our LORD as a human, He endured the harshest of temptations. MAN has faced similar things (all humans) and each have failed long before the level of Jesus' temptation. Jesus endured these things and triumphed over them. The devil left Him after being resisted, and we are told the same will happen for us as we are obedient in resisting the devil. It does not mean the temptation won't return, but that there is a limit to what Satan can do to us.
If the feeble mind of man must find a word or idea to describe the relationship of God and the human body with which He clothed Himself. The use of SYNERGISTIC, may not be completely incorrect in the general use of the word, but the situation was so unique as to NOT be subject to such a pigeonhole. Already, even here, the thoughts that this made Christ subject to failing in sin have been entertained by some. My main problem with the whole concept is how the finite mind uses only what it understands to describe what it cannot understand.
This does not even begin to cover the issues of the infinite complexity of God's manner of reconciling that which could not be physically, spiritually or even legally reconciled. Our understanding is enough to grasp His requirements of us, but Christians will likely have an eternity of discovering the depths of what God has done for us.
