I think you need to read a bit closer what I actually said: "
Phil 2:6 most certainly is part of
a trinitarian passage. It makes no sense if the Son wasn't God and it makes no sense if the Son really was the Father."
My point is that the whole context of Phil 2:6 (I've never heard or read a trinitarian who argued to only Phil 2:6) is thoroughly Trinitarian. In the very least, it proves the deity of Jesus. But, given that the Son is not the Father, it also proves the Trinity.
Php 2:5 Have this mind among yourselves, which is yours in Christ Jesus,
Php 2:6 who,
though he was in the form of God, did not count equality with God a thing to be grasped,
Php 2:7 but
emptied himself, by taking the form of a servant, being born in the likeness of men.
Php 2:8 And
being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
Php 2:9 Therefore God has highly exalted him and bestowed on him the name that is above every name,
Php 2:10 so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth,
Php 2:11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. (ESV)
Some important points to note about this passage:
1. Jesus was in "the form of God." This is supported by
John 1:1--"the Word was with God, and the Word was God." The NIV has a clearer rendering of what is meant in verse 6: "being in very nature God."
The Expositor's Greek Testament and M. R. Vincent (
Word Studies in the New Testament) agree. That Paul is referring to the divinity of Christ is without question.
2. He "did not count equality with God a thing to be grasped"; that is, being in the form of God, being equal with the Father, he did not consider that equality something to be "forcefully retained [or held onto]." The meaning is that anything to do with the appearance of his glory as God had to be let go of in order for the completion of his humiliation, which was necessary for man's salvation. Again, the NIV brings out the meaning a bit better: "did not consider equality with God something to be used to his own advantage."
3.
He, being Jesus, emptied
himself. Firstly then, it was he who did the emptying. And, secondly,
he emptied himself of something. That is, there is something that he emptied himself of something that was necessary in the taking on of a human form. Jesus willingly chose to take the form of a human for the salvation of mankind. Whatever Paul means here, and we must always be careful to not say more or less than what the Bible says, Jesus, as God Incarnate, still maintains his full deity in becoming truly and fully human.
4. In emptying himself, he took on the "form of a servant," "being born in the likeness of men"--this is what
John 1:14 is speaking of. Paul is contrasting Jesus's "being born in the likeness of men" with being in the "form of God."
5. Being found in "human form"--again, as opposed to his having been in "the form of God"--he "
humbled himself by becoming obedient."
The whole point of this passage is to show the humility of Christ, which we are to have (verses 1-5). There is no greater example of humility that could be conceived than that of God (the Son) coming to earth and taking on the form of one of his creatures.
