The word “deity” does not appear in all Bible translations, and it is not defined in most Bible dictionaries and encyclopedias,
I noticed this on your site. It needs clarification because it is wrong. I haven't read all Bible dictionaries and encyclopedias so I don't know if most don't address the issue, but where it is addressed in Strong and Vines, it completely disagrees with your assesment. This is what I wrote in that regard.
Colossians 2:9 is convincing evidence of the divinity of Christ. It states of Christ that “in Him dwells all the fullness of the Godhead bodily” (Green’s Literal Translation). The Greek word for “Godhead” is theotes and means divinity. It “stresses deity, the state of being God (Strong and Vine’s, 115). It is to be distinguished from theiotes which refers to the attributes of God, his divine nature and properties and it is this definition which the Jehovah's Witnesses incorrectly attach to Col 2:9 when they claim that the Godhead there merely refers to His “divine qualities” (Reasoning, 420). This is manifestly incorrect according to Strong and Vine’s, and what the Jehovah's Witnesses are actually doing is swapping theiotes for theotes. Regarding the Godhead (theotes) at Colossians 2:9:
In Col 2:9, Paul is declaring that in the Son there dwells all the fullness of absolute Godhead; they were no mere rays of divine glory which gilded him, lighting up His Person for a season and with a splendor not His own; but He was, and is, absolute and perfect God; and the apostle uses theotes to express this essential and personal Godhead of the Son. Theotes indicates the divine essence of Godhood, the personality of God; (Strong and Vines, 114). [Theotes] stresses deity, the state of being God. (ibid, 115).
(Theiotes, on the other hand), … refers to the attributes of God, His divine nature and properties. (Strong and Vine’s, 114)
The Jehovah's Witnesses argue that “[b]eing truly “divinity,” or of “divine nature,” does not make Jesus as the Son of God coequal and coeternal with the Father, any more than humans are coequal or all the same age just because they share humanity or human nature” (Reasoning, 421). But that is not necessarily true. If all persons share humanity it does make them all human, and they are all equally “human.” One person is not more or less human than another. So, if the inevitability of death is one aspect of humanity, then all humans die, all are mortal; they are equal in that regard. Similarly, if divinity inherently includes an eternal nature, and Jesus and God are divine, of the same essence (consubstantial), then both are eternal.
Actually, the Jehovah's Witnesses’ comparison of Jesus with all humans who share humanity is another flawed analogy because Jesus doesn’t share God at all like humans have a share in humanity. Jesus is fully God, and not somehow made God by virtue of the hypostatic union.
At Hebrews 1:3 Christ is said to be “the very imprint of His (God’s) being” (NAB) (“the very stamp of his nature” (RS) (“the express image of His substance” (Strong and Vine’s, 269). The Greek word used here for image, stamp or imprint is charaktar and means an exact copy or representation, and stresses complete, not partial, similarity of essence.
(2) In the NT it is used metaphorically in Heb 1:3, of the Son of God as “the express image of His substance.” The phrase expresses the fact that the Son “is both personally distinct from, and yet literally equal to, Him of whose essence He is the imprint. The Son of God is not merely his “image” (His character), He is the “image” or impress of His substance, or essence. It is the fact of complete similarity which this word stresses. (Strong and Vine’s, 269)
Accordingly, such equality applies to His eternal existence, omnipotence and omniscient nature, as God and the Word are literally equal to each other with respect to their essential being.
Now, back to the topics.
