I think I misrepresented my position. This is very important, and I'm not arguing against trinity. It is speaking about the trinity but in a different way than saying Jesus is the word. All that I am saying is this passage does not claim Jesus equal God. It claims he is a light proceeding out of God. It does not bar him from also being one with God or me or you. The light is important for several reasons and not a restatement. These folks do not think of light as photons like we do. Light enters into all things revealing what is in them, both the world and the person. It judges. There is light that reveals the floor, and there is light that reveals the heart. It also has a further meaning. If Jesus proceeds as light from the Word, then it is suggesting he is the exact representation of the Word like the wax seal on an envelope bears the impression of a ring. It is like saying Jesus is the signature on the envelope, pressed with God's seal. This is good for trinitarian positions not bad. Look at the importance of light in Hebrews 1:3 "The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word." This all ties together and shows a common thought between John and Hebrews. Hebrews then says of the Son "Your throne, Oh God, will last forever and ever..."
In Revelation 21:23 the Lamb is the "Lamp" and the Light itself is God. So, Jesus is indeed shining the Light of God as a Lamp does. This is how Jesus is the "Light of the world". The Son of man is the Lamp and the Light within is God.
Also Jesus is the "Alpha and Omega" so He literally is spelling each Word that God speaks. Jesus is the Word of God.
John is unveiling the mystery hidden from the foundation of the world. We can't really understand John chapter 1 in a Trinitarian sense. We must look to Genesis chapter 1 which is what John 1 is about. looking at 1st John chapter 1 is also beneficial.
The Light of Life and the Word of Life is resurrection from the dead. It is Life overcoming death.
The darkness is the "shadow of death" as spoken of famously in Psalm 23 and Isaiah 9 and elsewhere in the scriptures. The "shadow of death" is the sentence of death that covers all people. As it is written "For, behold, the darkness shall cover the earth, and great darkness the people ..." The only way to overcome it and bring Life is through the resurrection from the dead. Jesus is the resurrection and the Life. He is the Sun of Righteousness that has healing in His wings. This is the Light of Genesis 1:3 that overcomes the darkness.
First He rises within us and so the resurrection is in the inner person. As it says ", until the day dawn, and the day star arise in your hearts ..." and then He will also be external when He raises the church up bodily from their graves.
