¹ tn Or “purifies.”

² tn BDAG 50 s.v. ἁμαρτία 1 defines this term as “a departure fr. either human or divine standards of uprightness” (see 1 John 5:17 where ἁμαρτία [Jamartia] and ἀδικία [adikia] are related). This word occurs 17 times in 1 John, of which 11 are singular and 6 are plural.

sn From all sin. Sometimes a distinction between singular “sin” and plural “sins” has been suggested: Some would see the singular all sin of 1:7 as a reference to sinfulness before conversion and the plural sins of 1:9 as a reference to sins committed after one became a Christian. This amounts to making 1:7 refer to initial justification and 1:9 to sanctification. But the phrase all sin in 1:7 is so comprehensive that it can hardly be limited to preconversion sins, and the emphasis on “walking” in 1:7 strongly suggests that the Christian life is in view (not one’s life before conversion). In 1 John 1:8 sin appears as a condition or characteristic quality, which in 1:10 is regarded as universal. Apart from forgiveness in Christ it results in alienation from God (2:15) and spiritual death (3:14). But according to 1 John 1:7, cleansing from sin is possible by the blood (representing the sacrificial death) of Jesus.

³ 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.

⁴ 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.

⁵ 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.

⁶ 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.”

⁷ 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.”

⁸ 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.”

⁹ 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.

¹⁰ 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.

¹¹ 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.”

¹² 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.

¹³ 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).

¹⁴ 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.

¹⁵ tn The verb μένω (menw) has been translated “resides” here because this verse refers to the mutual and reciprocal relationship between God and the believer.

sn The verb resides (μένω, menw) here and again in the second clause of 3:24 refers to the permanence of relationship between God and the believer, as also in 2:6; 4:12, 13, 15, and 16 (3x).

¹⁶ tn Grk “in him.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).

¹⁷ tn Grk “he.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).

¹⁸ tn Once again there is the (by now familiar) question of whether the phrase ἐν τούτῳ (en toutw) refers to what precedes or to what follows. In this case, the following phrase ἐκ τοῦ πνεύματος (ek tou pneumato") explains the ἐν τούτῳ phrase, and so it refers to what follows.

¹⁹ tn Grk “he.” In context this is almost certainly a reference to God (note the phrase “his Son Jesus Christ” in 3:23).
