Not in the slightest keypurr.
For the Greek word χαρακτήρ (character) in Heb 1:3, Vine's states;
the special function of creating and upholding the universe is ascribed to Christ under His titles of Word, Image, and Son, respectively. The kind of Creatorship so predicated of Him is not that of a mere instrument or artificer in the formation of the world, but that of One 'by whom, in whom, and for whom' all things are made, and through whom they subsist. This implies the assertion of His true and absolute Godhood" (Laidlaw, in Hastings' Bib. Dic.).
The fact is if you move OFF the one word you are fixated on, you will see that Jesus is described as; "sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven."
This describes God, not just a man.
Again as the scriptures say that ONLY God is our savior, Is 43:11-12 (NIV), then Jesus has to be God, because He is clearly our savior, or at least He is mine. Is He yours?
Of course I agree with StanJ in his main argument, represented here that Jesus is God....it seems however that however clearly scriptures states the fact the revelation can only come directly from God himself
