John 1:14

1:14 Now ¹  the Word became flesh ²  and took up residence ³  among us. We ⁴  saw his glory – the glory of the one and only, ⁵  full of grace and truth, who came from the Father.

John 1:18

1:18 No one has ever seen God. The only one, ⁶  himself God, who is in closest fellowship with ⁷  the Father, has made God ⁸  known. ⁹ 

Genesis 22:12

22:12 “Do not harm the boy!” ¹⁰  the angel said. ¹¹  “Do not do anything to him, for now I know ¹²  that you fear ¹³  God because you did not withhold your son, your only son, from me.”

Mark 12:6

12:6 He had one left, his one dear son. ¹⁴  Finally he sent him to them, saying, ‘They will respect my son.’

Romans 5:10

5:10 For if while we were enemies we were reconciled to God through the death of his Son, how much more, since we have been reconciled, will we be saved by his life?

Romans 8:32

8:32 Indeed, he who ¹⁵  did not spare his own Son, but gave him up for us all – how will he not also, along with him, freely give us all things?

¹ tn Here καί (kai) has been translated as “now” to indicate the transition to a new topic, the incarnation of the Word. Greek style often begins sentences or clauses with “and,” but English style generally does not.

² tn This looks at the Word incarnate in humility and weakness; the word σάρξ (sarx) does not carry overtones of sinfulness here as it frequently does in Pauline usage. See also John 3:6.

³ tn Grk “and tabernacled.”

⁴ tn Grk “and we saw.”

⁵ tn Or “of the unique one.” Although this word is often translated “only begotten,” such a translation is misleading, since in English it appears to express a metaphysical relationship. The word in Greek was used of an only child (a son [Luke 7:12, 9:38] or a daughter [Luke 8:42]). It was also used of something unique (only one of its kind) such as the mythological Phoenix (1 Clem. 25:2). From here it passes easily to a description of Isaac (Heb 11:17 and Josephus, Ant., 1.13.1 [1.222]) who was not Abraham’s only son, but was one-of-a-kind because he was the child of the promise. Thus the word means “one-of-a-kind” and is reserved for Jesus in the Johannine literature of the NT. While all Christians are children of God, Jesus is God’s Son in a unique, one-of-a-kind sense. The word is used in this way in all its uses in the Gospel of John (1:14, 1:18, 3:16, and 3:18).

⁶ 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 Ë^1,13 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.

⁷ tn Grk “in the bosom of” (an idiom for closeness or nearness; cf. L&N 34.18; BDAG 556 s.v. κόλπος 1).

⁸ tn Grk “him”; the referent (God) has been specified in the translation for clarity.

⁹ sn Has made God known. In this final verse of the prologue, the climactic and ultimate statement of the earthly career of the Logos, Jesus of Nazareth, is reached. 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.”

¹⁰ tn Heb “Do not extend your hand toward the boy.”

¹¹ tn Heb “and he said, ‘Do not extend…’”; the referent (the angel) has been specified in the context for clarity. The order of the introductory clause and the direct discourse has been rearranged in the translation for stylistic reasons.

¹² sn For now I know. The test was designed to see if Abraham would be obedient (see v. 1).

¹³ sn In this context fear refers by metonymy to obedience that grows from faith.

¹⁴ tn Grk “one beloved son.” See comment at Mark 1:11.

¹⁵ tn Grk “[he] who.” The relative clause continues the question of v. 31 in a way that is awkward in English. The force of v. 32 is thus: “who indeed did not spare his own Son, but gave him up for us all – How will he not also with him give us all things?”
