Who is the image of the invisible God, the firstborn of all creation:
All Commentaries on Colossians 1:15 Go To Colossians 1
Gregory the Theologian
AD 390
He is called “image” because he is of one substance with the Father; he stems from the Father and not the Father from him, it being the nature of an image to copy the original and to be named after it. But there is more to it than this. The ordinary image is a motionless copy of a moving being. Here we have a living image of a living being, indistinguishable from its original to a higher degree than Seth from Adam and any earthly offspring from its parents. Beings with no complexity to their nature have no points of likeness or unlikeness. They are exact replicas, identical rather than like.
