Col 1:19 and 2:9 clearly and emphatically state the FULLNESS of the Godhead dwells in Christ in bodily form.
If the FULLNESS of the Godhead dwells in Jesus Christ, then how much more of the Godhead needs to dwell in Him for Him to be considered God?
FRiend, that same "fullness" is found in Ephesians 3:19, where it refers not to Jesus but to all Christians.
Surely you would not suggest this means that all Christians are also God Himself?
FRiend, the key to understanding here is realizing that, first and foremost, New Testament writers were all Jews, and while they certainly believed in Christ's divinity, they would, as Jews, in no possible way compromise the Oneness of God.
If that creates certain theological problems, I would suggest those can well remain unanswered, since obviously nobody knows enough to more concretely define God.
