For in him dwells all the fullness of the Deity bodily.
All Commentaries on Colossians 2:9 Go To Colossians 2
Ambrose of Milan
AD 397
The law has proved God’s oneness. It speaks of one God, as also the apostle when he says of Christ: “In whom dwells all the fullness of the Godhead bodily.” For if, as the apostle says, all the fullness of the Godhead, bodily, is in Christ, then must the Father and the Son be confessed to be of one Godhead. Or if one desired to sunder the Godhead of the Son from the Godhead of the Father, as long as the Son possesses all the fullness of the Godhead bodily, what is supposed to be further reserved, seeing that nothing remains over and above the fullness of perfection? Therefore the Godhead is one. .
