katabiblon.com is a great interlinear of the NT and Septuagint.
It has an interesting footnote on Col 2:9:
Gr. θε?της, God-ness; that is, in him resides (in bodily form) everything you need as regards God-related stuff, such that nothing you need is to be obtained by turning to extraneous traditions and rules.
This is right in line with John 1:18. Jesus teaches us everything we need to know about God. The Father is beyond the realm of our comprehension, so man-made dogmas are unnecessary and likely to be wrong. Keep in mind, most English Bibles are translated by people just like you; people with agendas who see their dogma everywhere they look. So, when presented with an opportunity to interpret the Scriptures - which is occasionally necessary when translating - they lean toward their pre-conceived ideas. But that is dishonest and the Bible warns against adding to or taking away from God's Word.
I actually address John 1:1 in a post I've pointed you toward, before. If you have opted not to read it, then I'll opt not to repeat it.
As far as Philippians 2, even in the awkward translations that push the Trinity agenda by twisting the meaning, this passage does more harm than good for the Trinity:
God exalted him
and gave him the name
Jesus Christ is Lord, to the glory of God the Father
If God exalted Jesus, who is God again? If God gave Jesus the name above all others, who is God again? If Christ is Lord, to the glory of God the Father, who is God again?
Where this scripture is properly translated, it merely contrasts Jesus with Satan. Jesus didn't attempt a coup d'état in Heaven, even though he held a higher position than Satan. Jesus, the only-begotten and being above the angels, remained subservient to God, whereas Satan - a mere angel - rebelled and sought to usurp God's rule and upset the proverbial "apple cart".
Show me in the Bible where belief in the Trinity is required. You made this statement
The Deity of Christ is not negotiable, but essential, salvific truth.
and I want to know where you got it. I found it in a man-made creed (which you reject adherence to) but nowhere in Scripture (which is where you claim all your beliefs come from).
One cannot be a Christian and deny who He is (God).
So, when Jesus said "the Father is greater than I", " the Father who sent me", " I love the Father and do exactly what my Father has commanded me", " I will ask the Father", " no one knows, not even the angels in heaven, nor the Son, but only the Father", etc, etc, etc... was he just screwing with us and making it impossible to understand, then later demanding we believe something he'd denied the whole time he was here? The Trinity calls Jesus a liar and that is entirely unChristian. The Hellfire doctrine maligns God and the Trinity doctrine insults Jesus. The way you're shouting them from the rooftops, I'd hate to be in your shoes.
