Paidion-Certainly Jesus was not "fully God" and "fully man" in the same sense.
But to say that He was "half man" and "half God" is even worse!
While Jesus walked on earth He was "fully God" in a different sense than the Father was "fully God". According to scripture He had divested Himself of His divine attributes, and became fully a human being. The ONLY thing He retained of His divinity as the only-begotten God, was His identity. He was the same Son of God as He was prior to His birth on earth.
"Before Abraham was, I am."
So in that sense, and in that sense only, He was fully God here upon the earth. In every other way, He was fully human.
I like the way you think. Clearly the scriptures teach that Jesus had a pre-existence with the Father. Philippians 2 teaches that he did divest himself of his divine attributes. Scripture also seems to teach a supremacy of God the Father over the Lord Jesus Christ, not a co-equality. In Philippians 2, it is God who exalted Jesus. How can one exalt another to a higher position unless he occupies a higher position? Also in Philippians 2, the end result of every tongue confessing that Jesus is Lord is the glory of God the Father. Scripture also states in several places that Jesus is at the right hand of God. The implication is that the one who is at the right hand of another is subordinate to the one whose right hand he is at. i.e. The king's right hand man carries out the wishes of the king.
This however is far different from the meaning that most Evangelicals ascribe to the phrase "Fully God and fully man." I clench my teeth when I sit in church and hear that God died on the cross. When I read the word GOD in Scripture, my assumption is that it is talking about The Father. I think that this is mostly a good assumption. In 1Cor. 8:6, Paul says, "but for us, there is one God, The Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things, and through whom we exist." (God the Father= the source of creation, Jesus Christ= the instrument of creation) All of Paul's letters begin with some version of the salutation, "Grace to you and peace from God the Father and the Lord Jesus Christ. It seems to me that the early Christians, certainly the apostle Paul, saw Jesus Christ and God the Father as two very separate and distinct beings. Modern day Trinitarians have blended and blurred the two persons to an extent that I don't see in scripture.The ONLY thing He retained of His divinity as the only-begotten God, was His identity. He was the same Son of God as He was prior to His birth on earth.
