[1:2]  ¹ tn Or “proclaim.”

[1:2]  ² tn In the Greek text the prologue to 1 John (vv. 1-4) makes up a single sentence. This is awkward in Greek, and a literal translation produces almost impossible English. For this reason the present translation places a period at the end of v. 2 and another at the end of v. 3. The material in parentheses in v. 1 begins the first of three parenthetical interruptions in the grammatical sequence of the prologue (the second is the entirety of v. 2 and the third is the latter part of v. 3). This is because of the awkwardness of connecting the prepositional phrase with what precedes, an awkwardness not immediately obvious in most English translations: “what we beheld and our hands handled concerning the word of life…” As J. Bonsirven (Épîtres de Saint Jean [CNT], 67) noted, while one may hear about the word of life, it is more difficult to see about the word of life, and impossible to feel with one’s hands about the word of life. Rather than being the object of any of the verbs in v. 1, the prepositional phrase at the end of v. 1 (“concerning the word of life…”) is more likely a parenthetical clarification intended to specify the subject of the eyewitness testimony which the verbs in v. 1 describe. A parallel for such parenthetical explanation may be found in John 1:12 (τοῖς πιστεύουσιν εἰς τὸ ὄνομα αὐτοῦ, toi" pisteuousin ei" to onoma autou).

[2:8]  ³ tn “In him” probably refers to Jesus Christ since the last third person pronoun in 2:6 referred to Jesus Christ and there is no indication in the context of a change in referent.

[2:8]  ⁴ tn The clause beginning with ὅτι (Joti) is often taken as (1) epexegetical or (2) appositional to the commandment (ἐντολήν, entolhn) giving a further explanation or clarification of it. But the statement following the ὅτι is about light and darkness, and it is difficult to see how this has anything to do with the commandment, especially as the commandment is related to the “new commandment” of John 13:34 for believers to love one another. It is far more likely that (3) the ὅτι clause should be understood as causal, but this still does not answer the question of whether it offers the reason for writing the “new commandment” itself or the reason for the relative clause (“that is true in him and in you”). It probably gives the reason for the writing of the commandment, although R. E. Brown (Epistles of John [AB], 268) thinks it refers to both.

[2:8]  ⁵ sn The reference to the darkness…passing away and the true light…already shining is an allusion to John 1:5, 1:9, and 8:12. Because the author sees the victory of light over darkness as something already begun, he is writing Jesus’ commandment to love one another to the readers as a reminder to (1) hold fast to what they have already heard (see 1 John 2:7) and (2) not be influenced by the teaching of the opponents.

[4:17]  ⁵ tn The referent of ἐν τούτῳ (en toutw) here is more difficult to determine than most, because while there are both ἵνα (Jina) and ὅτι (Joti) clauses following, it is not clear whether or not they are related to the ἐν τούτῳ. There are actually three possibilities for the referent of ἐν τούτῳ in 4:17: (1) it may refer to the ἵνα clause which immediately follows, so that the love of believers is brought to perfection in that they have confidence in the day of judgment. The main problem with this interpretation is that since the day of judgment is still future, it necessitates understanding the second use of the preposition “in” (second ἐν [en]) to mean “about” or “concerning” with reference to the day of judgment in order to make logical sense. (2) The ἐν τούτῳ may refer to the ὅτι clause in 4:17b, meaning “love is perfected with us…in that just as he [Christ] is, so also are we in this world.” This makes logical sense, and there are numerous cases where ἐν τούτῳ is explained by a ὅτι clause that follows. However, according to this understanding the intervening ἵνα clause is awkward, and there is no other instance of the phrase ἐν τούτῳ explained by a following ὅτι clause where a ἵνα clause intervenes between the two in this way. (3) Thus, the third possibility is that ἐν τούτῳ refers to what precedes in 4:16b, and this also would make logical sense: “By this – by our residing in love so that we reside in God and he resides in us – is love brought to perfection with us.” This has the additional advantage of agreeing precisely with what the author has already said in 4:12: “If we love one another, God remains in us and his love is brought to perfection in us.” Thus option (3) is best, with the phrase ἐν τούτῳ referring to what precedes in 4:16b, and the ἵνα clause which follows indicates the result of this perfection of love in believers: In the future day of judgment they will have confidence. The ὅτι clause would then give the reason for such confidence in the day of judgment: because just as Jesus is, so also are believers in this world – they are already currently in relationship with God just as Jesus is.

[4:17]  ⁶ tn The preposition μετά (meta) means “with” and modifies the verb τετελείωται (teteleiwtai). If the prepositional phrase modified the noun ἡ ἀγάπη which immediately precedes it, it would almost certainly have the Greek article, thus: ἡ ἀγάπη ἡ μεθ᾿ ἡμῶν (Jh agaph Jh meq’ Jhmwn).

[4:17]  ⁷ tn Grk “that one” (a reference to Jesus is indicated in the context). Once more the author uses the pronoun ἐκεῖνος (ekeinos) to refer to Jesus Christ, as he did in 2:6; 3:3, 5, 7, and 16. A reference to Christ is confirmed in this context because the author says that “just as he is, so also are we [believers] in this world” and since 3:2 indicated that believers are to be like God in the future (but are not yet), the only one believers can be like already in the present age is Jesus Christ.
