John 1:14 (ESV)
14And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
you really miss the obvious. Of course Jesus came in the flesh. That was the purpose of incarnation. duh.
You take the obvious verse of his ultimate divinity of being God and you try to use that passage to reject what was just shared about the Word. I'm not sure how you can miss so many details and still argue for the unitarian idea. I think you are running out of ideas to argue since everything else has failed to support your view.
