The last reference from verse 18 corresponds with that of verse 1,
as is seen by the structure:
`The Word was God' (as to His substance or essence).
`No man hath seen God' (as to His substance or essence).
A similar usage of the article, or rather of its absence, is found in
verse 14: `The Word was made flesh'. It would be manifestly absurd
to translate this `The Word was made a flesh'.
The word Theos is used of God in the Scriptures in three different
ways:
(1) Essentially, as in John 4:24: `God is Spirit'.
(2) Personally, as of the Father: `God the Father' (Gal. 1:1).
Personally, as of the Son: `Unto the Son, He saith ... O God'
(Heb. 1:8).
Personally, as of the Spirit: `The Holy Ghost ... God' (Acts
5:3,4).
(3) Manifestly, as of the Word: `The Word was God' (1:1).
In the narrative section of the Gospel, John seizes many
opportunities to bring into prominence the controversy concerning the
Deity of Christ. These passages will come before us in their order as
we follow the exposition of the Gospel, but there are three that most
readers will call to mind that seem to carry the theme forward from
argument and hostility to adoration and worship:
(1) `Therefore the Jews sought the more to kill Him, because He
not only had broken the sabbath, but said also that God was His
Father, making Himself equal with God' (5:18).
(2) `I and My Father are one. Then the Jews took up stones again
to stone Him ... Thou, being a man, makest Thyself God'
(10:30-33).
(3) `Thomas answered and said unto Him, My Lord and my God'
(20:28).
We have already seen that it is the object of this Gospel to expand
and prove the truth revealed in the prologue, and we shall hope to deal
in detail with the passages quoted above as we come to them in the
course of our exposition.
