1. “In the Philippian passage we see that it was the Son of God who emptied himself”
The context says the one who emptied Himself was made in the likeness of men. It appears clear to me that the only one in this passage who was “in the likeness of men” was “Jesus the man”.
"Is Paul speaking here in Phil 25-8 about the pre-incarnate or about the incarnate Christ?" It is not difficult to answer. The two must not be separated. The One who in his pre-incarnate state [Son of God] exists in a manner equal to God and is the same divine Person who in his incarnate state becomes obedient even to the extent of death,...Naturally, in order to show the greatness of our Lord's sacrifice, the apostle's
starting-point is the Christ in his pre-incarnate state. Then follows of necessity Christ in his incarnate state. This strongly reminds one of 2Cor 8:9. 'Though he was rich, yet for your sake he became poor.' One might compare this transition to what is found in the Gospel of John, Chapter 1: 'In the beginning was the Word, and the Word was face to face with God, and the Word was God. He himself was in the beginning face to face with God . . . And the Word became flesh, and dwelt among us as in a tent, and we beheld his glory.'"
Again, one must carefully distinguish between the divine and the human natures of Christ and not confuse them which you are wanting to do. The divine nature, the Son of God is eternal but the human nature is temporal; i.e., it had a beginning but with no end.
2.“God remained the eternal God, the creator of all things while the human nature, Jesus of Nazareth remained perfectly human.”
When Jesus asked his disciple who do you say that I am. Peter, looking at Jesus the man said, "You are the Christ, the Son of the living God." And Jesus said to him, "Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven. From here it is reasonable to conclude that Jesus the man was also the Son of God “at the same time”. In other words, being human did not stop him from being God. (More on this later.)
Yes, the LORD Christ was both divine and human. There is no dispute concerning this truth. The issue is whether
Jesus in his incarnate state was eternal. I, along with the entire Church answers, "No!", but you answer, "Yes!". More on this later.
4. “according to the divine testimony, the Lamb was already considered as “slain from the foundation of the world”.
Important point! If he was consider “slain before the foundation of the world” he should be consider to be “Jesus before the foundation of the world”.
An illogical leap without warrant. ALL things were considered as done before the foundation of the world, but that does not mean all things existed before the foundation of the world. To do so, in the least, would negate prophecy; a foretelling of that which did not exist but would happen later in space and time.
5. “How could a man who was born into this world in space and time have created all things?”
Being man and God at one time in history does not require he be in the form of a man at the beginning of time.
Oh, but it certainly does, otherwise the incarnation was not real, which I have already pointed out to you. Two distinct natures were joined in the one person of Jesus Christ. And until that supernatural event occurred, the human nature did not exist. Again, I already pointed this out as well, e.g., "For unto us a child is born, unto us a son is given;..." Isa 9:6a. A 'child' [Jesus, son of Mary] was born, i.e., it came into existence for the very first time. A 'son' [God the Son] was given, i.e., one who already existed.
6. To state that Jesus was the "Word" (Jh 1:1-3) vs. the Son of God was the "Word, is to deny the incarnation (Jh 1:14). For Jesus of Nazareth having been CONCEIVED by the Holy Spirit was BORN of the virgin Mary, and thus cannot be eternal.
I do not believe the human body of Jesus was eternal or that the human body of Jesus was involved in creation. I do not see where anything I said denies the incarnation. See 4 above regarding your statement related to divine testimony. It supports my view.
I have already addressed this as well on several occasions. Jesus did not exist in eternity and thus could not have created all things. You can say you aren't denying the incarnation, but this is exactly what you are doing.
7. “The divine nature of Jesus Christ did not 'die', but rather the human nature died.”
You need to define “nature” for me to understand what you are saying. I believe the Bible is clear regarding what died. The human body of Jesus died.
No, it was not
just the 'human body of Jesus' that died. This is yet another serious error. It was the human NATURE of Christ that died, i.e., that which constitutes a human died; both body and spirit. There are 2 natures co-existing in the one person of the Lord Jesus Christ; divine and human. The Son of God did not occupy just a fleshly shell. But rather two distinct natures were present. I've already covered this too.
Now about those substitutions, in the gospel of John,
John 1:1-5 "In the beginning was the Word,..." John uses “the Word” to emphasis the role of Jesus as “God’s communicator to man” and as “the one who spoke man into existence” (Gen 1:26).
You are
assuming the very issue in dispute. The "Word" is the eternal Son of God; the second person of the divine Trinity and NOT as you are
assuming, Jesus of Nazareth.
In general, I believe you need to understand that different names given to Jesus has more to do with his role at a particular time then it does with compartmentalizing His internal nature. When I start compartmentalizing his internal nature I begin to walk on thin ice and a branch that may or may not be connected to the vine. I also create new revelation that can be disagreed with which can cause division and leads to claims of heresy here, there and everywhere! Man has been complicating simple things since the fall. The first commandment was simple, “you shall not eat” but man (being man), decided to explore another option and life began to be complicated (Gem 2:16-17)...
I have deliberately included your entire statement in the above quote in order to show just how astray you have gone in your denial of what the entire Church has affirmed in the Chalcedon Creed. You cannot intermix the two natures but rather they must be acknowledged. The eternal Son of God is nowhere called "Jesus" UNTIL the incarnation, wherein the Son of God BECAME flesh; i.e., joined Himself with a human nature.
Gen 1:26-27... John 20:28-29What is it about me that is made in the image of God? Isn’t it my spirit? If my spirit is in me throughout my life here on earth could the spirit of the Son be in Jesus during his earthly ministry? Notice in John 20, Thomas is looking at the body of Jesus while calling him God. Isn’t he addressing the body and spirit of the Son here?
What?

Are you now asserting that the eternal Son of God, the second person of the Trinity has a "spirit"?
Mark 7:1-8... And He said to them, "Rightly did Isaiah prophesy of you hypocrites, as it is written: THIS PEOPLE HONORS ME WITH THEIR LIPS, BUT THEIR HEART IS FAR AWAY FROM ME. BUT IN VAIN DO THEY WORSHIP ME,TEACHING AS DOCTRINES THE PRECEPTS OF MEN.' Neglecting the commandment of God, you hold to the tradition of men." NASU
Man seems to have a need to add definition and detail to things that God has said.
What are your thoughts here?
Those without the Spirit of God will always add or detract from the Word of God and make their man-made traditions on par or above the Word of God in authority. However, interpreting Scripture and codifying its teachings is hardly the same as unbiblical man-made tradition. It is God's intent for His people to not only read His inspired written Word but to interpret and then apply it. This is what the Church has done from the beginning. Jude calls it "the faith once delivered unto the saints." This phrase isn't simply referring to the Bible, but the teachings of the Bible which the Apostles gave during their earthly ministry. Even the apostle Paul humbled himself and submitted his
teachings before the elders at Jerusalem in order that they might be scrutinized and either be found wanting or acceptable. Paul also counseled Timothy to hold fast to the doctrines he had been taught. The Church was given certain gifted individuals; pastor/teachers who were to instruct the people of God from Scripture. Throughout history, the Church has put into writing summaries of biblical truth found in its Confessions and Catechisms. There are good traditions and bad traditions, e.g., read John Murray's excellent article,
Tradition: Romish and Protestant.
Do you own one or more systematic theology books? Have you ever read them? If so, which do you have? OR, do you believe you have no use for such works because you only need your Bible? Do you seriously believe that all that have gone before you have erred on this subject, e.g., Augustine, Tertullian, Luther, Calvin, Owen, Edwards, Hodge, Berkhof, etc., etc...? Are you of the opinion that the entire Church has failed to grasp the truth of this matter for 2000+ years but you have discovered the 'truth'? Personally, from my own studies and having compared them to myriad volumes I find that what I believe to be in 100% accord with what the Church has believed and taught. Can you say the same? Or, again is it that what others have believed and taught, set in writing as secondary authorities, are of no importance to you?
