[1:18] 1 tc The textual problem μονογενὴς θεός (monogenh" qeo", “the only God”) versus ὁ μονογενὴς υἱός (Jo monogenh" Juio", “the only son”) is a notoriously difficult one. Only one letter would have differentiated the readings in the mss, since both words would have been contracted as nomina sacra: thus qMs or uMs. Externally, there are several variants, but they can be grouped essentially by whether they read θεός or υἱός. The majority of mss, especially the later ones (A C3 Θ Ψ Ë1,13 Ï lat), read ὁ μονογενὴς υἱός. Ì75 א1 33 pc have ὁ μονογενὴς θεός, while the anarthrous μονογενὴς θεός is found in Ì66 א* B C* L pc. The articular θεός is almost certainly a scribal emendation to the anarthrous θεός, for θεός without the article is a much harder reading. The external evidence thus strongly supports μονογενὴς θεός. Internally, although υἱός fits the immediate context more readily, θεός is much more difficult. As well, θεός also explains the origin of the other reading (υἱός), because it is difficult to see why a scribe who found υἱός in the text he was copying would alter it to θεός. Scribes would naturally change the wording to υἱός however, since μονογενὴς υἱός is a uniquely Johannine christological title (cf. John 3:16, 18; 1 John 4:9). But θεός as the older and more difficult reading is preferred. As for translation, it makes the most sense to see the word θεός as in apposition to μονογενής, and the participle ὁ ὤν (Jo wn) as in apposition to θεός, giving in effect three descriptions of Jesus rather than only two. (B. D. Ehrman, The Orthodox Corruption of Scripture, 81, suggests that it is nearly impossible and completely unattested in the NT for an adjective followed immediately by a noun that agrees in gender, number, and case, to be a substantival adjective: “when is an adjective ever used substantivally when it immediately precedes a noun of the same inflection?” This, however, is an overstatement. First, as Ehrman admits, μονογενής in John 1:14 is substantival. And since it is an established usage for the adjective in this context, one might well expect that the author would continue to use the adjective substantivally four verses later. Indeed, μονογενής is already moving toward a crystallized substantival adjective in the NT [cf. Luke 9:38; Heb 11:17]; in patristic Greek, the process continued [cf. PGL 881 s.v. 7]. Second, there are several instances in the NT in which a substantival adjective is followed by a noun with which it has complete concord: cf., e.g., Rom 1:30; Gal 3:9; 1 Tim 1:9; 2 Pet 2:5.) The modern translations which best express this are the NEB (margin) and TEV. Several things should be noted: μονογενής alone, without υἱός, can mean “only son,” “unique son,” “unique one,” etc. (see 1:14). Furthermore, θεός is anarthrous. As such it carries qualitative force much like it does in 1:1c, where θεὸς ἦν ὁ λόγος (qeo" hn Jo logo") means “the Word was fully God” or “the Word was fully of the essence of deity.” Finally, ὁ ὤν occurs in Rev 1:4, 8; 4:8, 11:17; and 16:5, but even more significantly in the LXX of Exod 3:14. Putting all of this together leads to the translation given in the text.

The unique One (John 1:14), the One who has taken on human form and nature by becoming incarnate (became flesh, 1:14), who is himself fully God (the Word was God, 1:1c) and is to be identified with the ever-living One of the Old Testament revelation (Exod 3:14), who is in intimate relationship with the Father, this One and no other has fully revealed what God is like. As Jesus said to Philip in John 14:9, “The one who has seen me has seen the Father.”
