¹ 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 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.

³ 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 sn The one who hates his fellow Christian. The author’s paradigm for the opponents portrays them as those who show hatred for fellow Christians (Grk “brothers,” but not referring to one’s physical siblings). This charge will be much more fully developed in chap. 3, where the author will compare the opponents to Cain (who is the model for one who hates a brother, since he ultimately murdered his own brother). In 1 John 3:17 the specific charge against the opponents will be failing to give material aid to a brother in need.

⁵ sn 1 John 2:3-11. The section 2:3-11 contains three claims to intimate knowledge of God, each introduced by the phrase the one who says (participles in the Greek text) in 2:4, 6, and 9. As with the three claims beginning with “if” in the previous section (1:6, 8, 10), these indirectly reflect the claims of the opponents. Each claim is followed by the author’s evaluation and its implications.

⁶ tn The genitive βίου (biou) is difficult to translate: (1) Many understand it as objective, so that βίος (bios, “material life”) becomes the object of one’s ἀλαζονεία (alazoneia; “pride” or “boastfulness”). Various interpretations along these lines refer to boasting about one’s wealth, showing off one’s possessions, boasting of one’s social status or lifestyle. (2) It is also possible to understand the genitive as subjective, however, in which case the βίος itself produces the ἀλαζονεία. In this case, the material security of one’s life and possessions produces a boastful overconfidence. This understanding better fits the context here: The focus is on people who operate purely on a human level and have no spiritual dimension to their existence. This is the person who loves the world, whose affections are all centered on the world, who has no love for God or spiritual things (“the love of the Father is not in him,” 2:15).

sn The arrogance produced by material possessions. The person who thinks he has enough wealth and property to protect himself and insure his security has no need for God (or anything outside himself).

⁷ tn The ἵνα (Jina) clause is best understood (1) as epexegetical (or explanatory), clarifying the love (ἀγάπην, agaphn) that the Father has given to believers. Although it is possible (2) to regard the ἵνα as indicating result, the use of ποταπήν (potaphn, “what sort of”) to modify ἀγάπην suggests that the idea of “love” will be qualified further in the following context, and this qualification is provided by the epexegetical ἵνα clause.

⁸ tn “Indeed” is not in the Greek text but is supplied to indicate emphasis.

⁹ tc The phrase καὶ ἐσμεν (kai esmen, “and we are”) is omitted in 049 69 Ï. There seems to be no theological reason to omit the words. This has all the earmarks of a classic case of homoioteleuton, for the preceding word (κληθῶμεν, klhqwmen, “we should be called”) ends in -μεν (-men).

tn The indicative mood indicates that the verb ἐσμέν (esmen) at the end of 3:1a is not governed by the ἵνα (Jina) and does not belong with the ἵνα clause, since this would have required a subjunctive. If the verb ἐσμέν were subjunctive, the force of the clause would be “that we should be called children of God, and be (children of God).” With ἐσμέν as indicative, the clause reads “that we should be called children of God, and indeed we are (children of God).”

¹⁰ tn Lexically it is clear that this phrase indicates reason, but what is not clear is whether (1) τοῦτο (touto) refers to what follows, (2) to what precedes, or (3) to both (as with the ἐν τοῦτο [en touto] phrases throughout 1 John). Διὰ τοῦτο (dia touto) occurs 15 times in the Gospel of John, and a pattern emerges which is so consistent that it appears to be the key to the usage here. Six times in the Gospel of John (5:16, 18; 8:47; 10:17; 12:18, 39) the phrase refers to what follows, and in each of these instances an epexegetical ὅτι (Joti) clause follows. Nine times in John (1:31, 6:65, 7:21-22, 9:23, 12:27, 13:11, 15:19, 16:15, 19:11) the phrase refers to what precedes, and in none of these instances is it followed by a ὅτι clause. The phrase διὰ τοῦτο is used three times in the Johannine Epistles. In two of these (1 John 4:5, 3 John 10) there is no ὅτι clause following, and so the διὰ τοῦτο should refer to preceding material. Here in 3:1 there is an epexegetical ὅτι clause following, so the διὰ τοῦτο should (unless it is the only exception in the Gospel of John and the Johannine Epistles) refer to what follows, that is, to the ὅτι clause itself. This is indicated by the colon in the translation.

¹¹ sn The pronoun him is a clear reference to Jesus Christ (compare John 1:10).

¹² tn The subject of the third person singular passive verb ἐφανερώθη (efanerwqh) in 3:2 is the following clause τί ἐσόμεθα (ti esomeqa): “Beloved, now we are children of God, and what we shall be has not yet been revealed.”

sn What we will be. The opponents have been revealed as antichrists now (2:19). What believers will be is to be revealed later. In light of the mention of the parousia in 2:28, it seems likely that an eschatological revelation of the true character of believers is in view here.

¹³ tc The Byzantine text, the Syriac Peshitta, the Bohairic Coptic, and one ms of the Sahidic Coptic supply δέ (de) after οἴδαμεν (oidamen) in 3:2b. Additions of coordinating conjunctions such as δέ are predictable variants; this coupled with the poor external credentials suggests that this addition is not likely to be original.

tn The relationship of 3:2b to 3:2a is difficult. It seems best to regard this as a case of asyndeton, although the Byzantine text, the Syriac Peshitta, the Bohairic Coptic, and some mss of the Sahidic Coptic supply δέ (de) after οἴδαμεν (oidamen) in 3:2b. This addition is not likely to be original, but it does reflect a tendency among scribes to see an adversative (contrastive) relationship between 3:2a and 3:2b. This seems to be an accurate understanding of the relationship between the clauses from a logical standpoint: “and what we shall be has not yet been revealed; but we know that whenever he should be revealed, we shall be like him.”

¹⁴ tn The first ὅτι (Joti) in 3:2 follows οἴδαμεν (oidamen), a verb of perception, and introduces an indirect discourse clause which specifies the content of what believers know: “that whenever it should be revealed, we shall be like him.”

¹⁵ tn In this context ἐάν (ean) does not indicate (1) uncertainty about whether or not what believers will be shall be revealed, but rather (2) uncertainty about the exact time the event will take place. In the Koine period ἐάν can mean “when” or “whenever” and is virtually the equivalent of ὅταν (Jotan; see BDAG 268 s.v. ἐάν 2). It has this meaning in John 12:32 and 14:3. Thus the phrase here should be translated, “we know that whenever it is revealed.”

¹⁶ tn Many take the understood subject (“he”) of φανερωθῇ (fanerwqh) as a reference to Jesus Christ, because the same verb was used in 2:28 in reference to the parousia (second advent). In the immediate context, however, a better analogy is ἐφανερώθη τί ἐσόμεθα (efanerwqh ti esomeqa) in 3:2a. There the clause τί ἐσόμεθα is the subject of the passive verb: “what we shall be has not yet been revealed.” From a grammatical standpoint it makes better sense to see the understood subject of φανερωθῇ as “it” rather than “he” and as referring back to the clause τί ἐσόμεθα in 3:2a. In the context this makes good sense: “Beloved, now we are children of God, and what we shall be has not yet been revealed. We know that whenever it shall be revealed, we shall be like him, because we shall see him just as he is.” This emphasizes the contrast in the verse between the present state (“not yet been revealed”) and the future state (“shall be revealed”) of believers, and this will of course take place at the parousia.

¹⁷ sn Is revealed. It may well be that the use of the same passive verb here (from φανερόω, fanerow) is intended to suggest to the reader the mention of the parousia (Christ’s second coming) in 2:28.

¹⁸ tn The second ὅτι (Joti) in 3:2 is best understood as causal, giving the reason why believers will be like God: “we shall be like him, because we shall see him just as he is.”

¹⁹ sn The phrase we will be like him, because we will see him just as he is has been explained two ways: (1) believers will really become more like God than they now are, and will do this through seeing God as he really is; or (2) believers will realize that they are already like God, but did not realize it until they see him as he is. One who sees a strong emphasis on realized eschatology in the Gospel of John and the Epistles might opt for the second view, since it downplays the difference between what believers already are in the present age and what they will become in the next. It seems better, though, in light of the statement in 3:2a that “what we will be has not yet been revealed” and because of the reference to Christ’s parousia in 2:28, that the author intends to distinguish between the present state of believers and what they will be like in the future. Thus the first view is better, that believers really will become more like God than they are now, as a result of seeing him as he really is.

²⁰ sn The person who practices sin is of the devil. 1 John 3:10 and John 8:44 might be cited as parallels, because these speak of opponents as the devil’s “children.” However, it is significant that the author of 1 John never speaks of the opponents as “fathered by the devil” in the same sense as Christians are “fathered by God” (3:9). A concept of evildoers as “fathered” by the devil in the same sense as Christians are fathered by God would imply a much more fully developed Gnosticism with its dualistic approach to humanity. The author of 1 John carefully avoids saying that the opponents are “fathered by the devil,” because in Johannine theology not to be fathered by God is to be fathered only by the flesh (John 1:13). This is a significant piece of evidence that 1 John predates the more fully developed Gnosticism of the 2nd century. What the author does say is that the opponents (“the one who practices sin”) are from the devil, in the sense that they belong to him and have given him their allegiance.

²¹ tn The present tense verb has been translated as an extending-from-past present (a present of past action still in progress). See ExSyn 520.

²² tn Here εἰς τοῦτο (eis touto) states the purpose for the revelation of God’s Son. However, the phrase offers the same difficulty as all the ἐν τούτῳ (en toutw) phrases in 1 John: Does it refer to what precedes or to what follows? By analogy with the ἐν τούτῳ construction it is probable that the phrase εἰς τοῦτο here refers to what follows: There is a ἵνα (Jina) clause following which appears to be related to the εἰς τοῦτο, and in fact is resumptive (that is, it restates the idea of “purpose” already expressed by the εἰς τοῦτο). Thus the meaning is: “For this purpose the Son of God was revealed: to destroy the works of the devil.”

²³ tn In the Gospel of John λύσῃ (lush) is used both literally and figuratively. In John 1:27 it refers to a literal loosing of one’s sandal-thong, and in John 2:19 to a destruction of Jesus’ physical body which was understood by the hearers to refer to physical destruction of the Jerusalem temple. In John 5:18 it refers to the breaking of the Sabbath, in John 7:23 to the breaking of the law of Moses, and in John 10:35 to the breaking of the scriptures. The verb is again used literally in John 11:44 at the resurrection of Lazarus when Jesus commands that he be released from the graveclothes with which he was bound. Here in 1 John 3:8 the verb means, with reference to “the works of the devil,” to “destroy, bring to an end, abolish.” See BDAG 607 s.v. λύω 4 and F. Büchsel, TDNT 4:336.

²⁴ sn Since the author states that Cain…was of the evil one (ἐκ τοῦ πονηροῦ, ek tou ponhrou), in the immediate context this imagery serves as an illustration of 3:8a: The person who practices sin is of the devil (ἐκ τοῦ διαβόλου, ek tou diabolou). This is similar to John 8:44, where Jesus told his opponents “you people are from your father the devil…[who] was a murderer from the beginning.” In both Jewish and early Christian writings Cain is a model for those who deliberately disbelieve; Testament of Benjamin 7:5 looks forward to the punishment of those who “are like Cain in the envy and hatred of brothers.” It is not difficult to see why the author of 1 John used Cain here as a model for the opponents in light of their failure to “love the brothers” (see 1 John 3:17).

²⁵ tn For the Greek verb σφάζω (sfazw) L&N 20.72 states, “to slaughter, either animals or persons; in contexts referring to persons, the implication is of violence and mercilessness – ‘to slaughter, to kill.’” As a reflection of this nuance, the translation “brutally murdered” has been used.

²⁶ 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.

²⁷ 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).

sn To say love is perfected with us means “with regard to our actions in loving our brothers.”

²⁸ 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.

²⁹ sn The entire phrase fear has to do with punishment may be understood in two slightly different ways: (1) “fear has its own punishment” or (2) “fear has to do with [includes] punishment.” These are not far apart, however, and the real key to understanding the expression lies in the meaning of the word “punishment” (κόλασις, kolasis). While it may refer to torture or torment (BDAG 555 s.v. 1) there are numerous Koine references involving eternal punishment (2 Macc 4:38; T. Reu. 5:5; T. Gad 7:5) and this is also the use in the only other NT reference, Matt 25:46. In the present context, where the author has mentioned having confidence in the day of judgment (4:17), it seems virtually certain that eternal punishment (or fear of it) is what is meant here. The (only) alternative to perfected love, which results in confidence at the day of judgment, is fear, which has to do with the punishment one is afraid of receiving at the judgment. As 4:18b states, “the one who fears [punishment] has not been perfected in love.” It is often assumed by interpreters that the opposite to perfected love (which casts out fear) is imperfect love (which still has fear and therefore no assurance). This is possible, but it is not likely, because the author nowhere mentions ‘imperfect’ love, and for him the opposite of ‘perfected’ love appears to be not imperfect love but hate (cf. 4:20). In other words, in the antithetical (‘either/or’) categories in which the author presents his arguments, one is either a genuine believer, who becomes ‘perfected’ in love as he resides in love and in a mutually indwelling relationship with God (cf. 4:16b), or one is not a genuine believer at all, but one who (like the opponents) hates his brother, is a liar, and does not know God at all. This individual should well fear judgment and eternal punishment because in the author’s view that is precisely where such a person is headed.

³⁰ tn Grk “punishment, and the person who fears.”

³¹ tn “Punishment” is not repeated in the Greek text at this point but is implied.

³² tn Grk “if anyone should say…”

³³ tn “Yet” is supplied to bring out the contrast.

³⁴ tn See note on the phrase “fellow Christian” in 2:9.

³⁵ tn See note on the phrase “fellow Christian” in 2:9.

³⁶ sn In 4:20 the author again describes the opponents, who claim to love God. Their failure to show love for their fellow Christians proves their claim to know God to be false: The one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.

³⁷ tn This ὅτι (Joti) is best understood (1) as causal. Some have taken it (2) as declarative, giving the content of the Spirit’s testimony: “and the Spirit is the One who testifies that the Spirit is the truth.” This is certainly possible, since a ὅτι clause following the cognate verb μαρτυρέω (marturevw) often gives the content of the testimony (cf. John 1:34; 3:28; 4:39, 44). But in the Gospel of John the Spirit never bears witness on his own behalf, but always on behalf of Jesus (John 15:26, 16:13). There are, in fact, some instances in the Gospel of John where a ὅτι clause following μαρτυρέω is causal (8:14, 15:27), and that is more likely here: “and the Spirit is the One who testifies, because the Spirit is the truth.”
