The μονογενής has “made Him known” or “explained Him.”[26] The unique One has made the Father known. Or, in light of the use of the term Father, the Only Son has revealed the Father. But this is not merely a dim reflection, a partial revelation, provided by the Only Son. This is the monogenes theos, the Only Son who is God. The divine nature of the μονογενής is again plainly asserted, just as it was in verse 1. This is what forms the “bookend,” the assertion in verse 1 that the Logos is divine, repeated and reaffirmed here in verse 18 with the statement that the Only Son is God.[27]
