Hello tigger 2!
It is great to be able to communicate with you! After having read some (not exhaustively) of what you have written on this forum and on your website, I wanted to share a few of my thoughts on Philippians chapter 2. But first let me state that I am no theologian, so though I believe the doctrine of the trinity please don't consider me any kind of authority or hold me too firmly to my ramblings
Regarding Phil. 2, I understand you to believe that "morphe" should be understood not to mean "nature" but rather "appearance" or "likeness to the eye" (for both verses 5 and 6...and morphe can indeed mean "appearance", as you have pointed out). Thus, we should understand this chapter to be compatible with the belief that Christ is a highly exalted created being that is perhaps very similar to God, but not God. If we assume this understanding of "morphe", however, I am inclined to believe that we lose the entire thrust of Paul's intent in this passage (2:1-11), which I believe you have rightly identified as an exhortation to humility.
Let me try to clarify. All created things are by their nature and appearance slaves/servants of God (if something is a servant of God, then its appearance is that of a servant of God). If Christ is a created being, then he has the nature and appearance (glorified to whatever degree) of a slave/servant--and has
always had the nature and appearance of such from the moment he was created (whatever his appearance or appearances, it/they would still be the appearance of a slave/servant). However, the language of verse 7 seems to quite clearly imply that before his incarnation, Christ did
not have the form of a slave/servant. Rather, he "
took a slave's [servant's] form" during the incarnation. If morphe in this passage means "appearance", then Paul's statement seems nonsensical. Why would Paul tell us that Christ "took" on the "appearance" of a slave/servant when he already had the appearance of one? I guess it could be said that Paul is telling us that Christ exchanged one appearance of a slave/servant (highly exalted spirit being appearance) for another (human appearance). I'm sure that such a transformation would be from higher to lower aesthetically, and to be willing to do that would take a measure of humility. But I don't think the context suggests that this is the thrust of Paul's use of Christ's example.
However, if we understand "morphe" to mean "nature" (which it can also sometimes mean), then the force of the passage really comes through. Christ, who from eternity was
not a servant by nature (only God is not a servant by nature),
took on the nature of a servant (to be human is to be a servant). This is condescension indeed and a better example of humility I don't think is possible to imagine. This condescension went beyond appearance to the character, actions, and attitude that Christ exemplified while on earth ("became obedient to the point of death"). It was an attitude that willingly forsook his rights and privileges in order to serve others who were not greater (either positionally or ontologically) than he. And this is the attitude that Christians should have towards one another--though we are all equal in Christ, we are to set aside any rights due to this fact and serve one another humbly and in love.
In regards to verse 6b, there are seemingly two different possible Greek renderings. One favors a unitarian view and the other a trinitarian view. I think Dr. James White does a good job discussing the possible interpretations in chapter 8 of his book, "The Forgotten Trinity".
May God direct you and I into his will and ways.
