Who is the image of the invisible God, the firstborn of every creature: Who is the image of the invisible God - The counterpart of God Almighty, and if the image of the invisible God, consequently nothing that appeared in him could be that image; for if it could be visible in the Son, it could also be visible in the Father; but if the Father be invisible, consequently his image in the Son must be invisible also. This is that form of God of which he divested himself; the ineffable glory in which he not only did not appear, as to its splendor and accompaniments, but concealed also its essential nature; that inaccessible light which no man, no created being, can possibly see. This was that Divine nature, the fullness of the Godhead bodily, which dwelt in him.
The first-born of every creature - I suppose this phrase to mean the same as that, Philippians 2:9 : God hath given him a name which is above every name; he is as man at the head of all the creation of God; nor can he with any propriety be considered as a creature, having himself created all things, and existed before any thing was made. If it be said that God created him first, and that he, by a delegated power from God, created all things, this is most flatly contradicted by the apostle's reasoning in the 16th and 17th verses. As the Jews term Jehovah בכורו של עולם becoro shel olam, the first-born of all the world, or of all the creation, to signify his having created or produced all things; (see Wolfius in loc.) so Christ is here termed, and the words which follow in the 16th and 17th verses are the proof of this. The phraseology is Jewish; and as they apply it to the supreme Being merely to denote his eternal pre-existence, and to point him out as the cause of all things; it is most evident that St. Paul uses it in the same way, and illustrates his meaning in the following words, which would be absolutely absurd if we could suppose that by the former he intended to convey any idea of the inferiority of Jesus Christ.
