[2:4]  ¹ tn Grk “know him.” See the note on the phrase “know God” in 1 John 2:3 for explanation.

[2:18]  ² sn Antichrists are John’s description for the opponents and their false teaching, which is at variance with the apostolic eyewitness testimony about who Jesus is (cf. 1:1-4). The identity of these opponents has been variously debated by scholars, with some contending (1) that these false teachers originally belonged to the group of apostolic leaders, but departed from it (“went out from us,” v. 19). It is much more likely (2) that they arose from within the Christian communities to which John is writing, however, and with which he identifies himself. This identification can be seen in the interchange of the pronouns “we” and “you” between 1:10 and 2:1, for example, where “we” does not refer only to John and the other apostles, but is inclusive, referring to both himself and the Christians he is writing to (2:1, “you”).

[2:21]  ³ tn The interpretation of the three ὅτι clauses in v. 21 is very difficult: (1) All three instances of ὅτι (Joti) may be causal (so NASB, NIV, NEB). (2) The first two may be causal while the third indicates content (declarative or recitative ὅτι, so KJV, RSV, TEV, NRSV). (3) However, it is best to take all three instances as indicating content because this allows all three to be subordinate to the verb ἔγραψα (egraya) as compound direct objects. The author writes to reassure his readers (a) that they do indeed know the truth (first two uses of ὅτι) and (b) that no lie is of the truth (third use).

[2:21]  ⁴ tn See the note on the first occurrence of “that” in v. 21.

[2:21]  ⁵ tn See the note on the first occurrence of “that” in v. 21.

[4:21]  ⁴ tn The ἵνα (Jina) clause in 4:21 could be giving (1) the purpose or (2) the result of the commandment mentioned in the first half of the verse, but if it does, the author nowhere specifies what the commandment consists of. It makes better sense to understand this ἵνα clause as (3) epexegetical to the pronoun ταύτην (tauthn) at the beginning of 4:21 and thus explaining what the commandment consists of: “that the one who loves God should love his brother also.”

[4:21]  ⁵ tn See note on the phrase “fellow Christian” in 2:9.

[5:3]  ⁵ tn The force of the γάρ (gar) at the beginning of 5:3 is similar to another introductory formula used by the author of 1 John, καὶ αὕτη ἐστίν (kai Jauth estin; used in 1:5; 5:4, 11, and 14). The γάρ draws an inference based on the preceding statements, particularly the one in 5:2b, regarding the love of God. If in 5:2 loving God and keeping his commandments is the key to knowing that we love God’s children, it is important to define what the love of God involves, and this is what the author is doing in 5:3. In fact, as the following ἵνα (Jina) clause makes clear, loving God consists in keeping his commandments.

[5:3]  ⁶ tn Once again the genitive could be understood as (1) objective, (2) subjective, or (3) both. Here an objective sense is more likely (believers’ love for God) because in the previous verse it is clear that God is the object of believers’ love.

[5:3]  ⁷ tn Contrary to the punctuation of NA²⁷ and UBS⁴, it is best to place a full stop (period) following τηρῶμεν (thrwmen) in 5:3. The subordinate clause introduced by ὅτι (Joti) at the beginning of 5:4 is related to the second half of 5:3 which begins with καί (kai). Καί is commonly used by the author to begin a new sentence, probably by analogy with the Hebrew vav consecutive.

[5:11]  ⁶ tn The ὅτι (Joti) clause in 5:11 is epexegetical (explanatory) to the phrase καὶ αὕτη ἐστίν (kai Jauth estin) at the beginning of the verse and gives the content of the testimony for the first time: “And this is the testimony: that God has given us eternal life, and this life is in his Son.”

[5:11]  ⁷ sn In understanding how “God’s testimony” (added to the three witnesses of 5:8) can consist of eternal life it is important to remember the debate between the author and the opponents. It is not the reality of eternal life (whether it exists at all or not) that is being debated here, but rather which side in the debate (the author and his readers or the opponents) possesses it (this is a key point). The letter began with a testimony that “the eternal life” has been revealed (1:2), and it is consummated here with the reception or acknowledgment of that eternal life as the final testimony. This testimony (which is God’s testimony) consists in eternal life itself, which the author and the readers possess, but the opponents do not. This, for the author, constitutes the final apologetic in his case against the opponents.

[5:13]  ⁷ tn Theoretically the pronoun ταῦτα (tauta) could refer (1) to what precedes or (2) to what follows. Since it is followed by a ἵνα (Jina) clause which gives the purpose for the writing, and a new subject is introduced in 5:14 (ἡ παρρησία, Jh parrhsia), it seems almost certain that the ταῦτα in 5:13 refers to preceding material. Even at this, some would limit the referent of ταῦτα (1) only to 5:1-12 or even 5:12, but more likely ταῦτα in 5:13 refers (2) to the entirety of the letter, for two reasons: (a) based on the structural analogy with the Gospel of John, where the conclusion refers to all that has preceded, it is probable that the conclusion to 1 John refers likewise to all that has preceded; and (b) the statement ταῦτα ἔγραψα ὑμῖν (tauta egraya Jumin) in 5:13 forms an inclusion with the statement καὶ ταῦτα γράφομεν ἡμεῖς (kai tauta grafomen Jhmei") at the end of the prologue (1:4) and encompasses the entire body of the letter.

[5:13]  ⁸ tn The dative participle πιστεύουσιν (pisteuousin) in 5:13 is in simple apposition to the indirect object of ἔγραψα (egraya), ὑμῖν (Jumin), and could be translated, “These things I have written to you, namely, to the ones who believe in the name of the Son of God, in order that you may know.” There is an exact parallel to this structure in John 1:12, where the pronoun is αὐτοῖς (autois) and the participle is τοῖς πιστεύουσιν (toi" pisteuousin) as here.

[5:13]  ⁹ tn This ἵνα (Jina) introduces a clause giving the author’s purpose for writing “these things” (ταῦτα, tauta), which refers to the entirety of the preceding material. The two other Johannine statements about writing, 1 John 1:4 and John 20:31, are both followed by purpose clauses introduced by ἵνα, as here.
