¹ tn The καί (kai) at the beginning of 1:5 takes on a resumptive force, indicated by the phrase “heard from him and announce to you,” which echoes similar phrases in 1:2 and 1:3.

² tn The word “gospel” is not in the Greek text but is supplied to clarify the meaning. See the note on the following word “message.”

³ tn The word ἀγγελία (angelia) occurs only twice in the NT, here and in 1 John 3:11. It is a cognate of ἐπαγγελία (epangelia) which occurs much more frequently (some 52 times in the NT) including 1 John 2:25. BDAG 8 s.v. ἀγγελία 1 offers the meaning “message” which suggests some overlap with the semantic range of λόγος (logos), although in the specific context of 1:5 BDAG suggests a reference to the gospel. (The precise “content” of this “good news’ is given by the ὅτι [Joti] clause which follows in 1:5b.) The word ἀγγελία here is closely equivalent to εὐαγγέλιον (euangelion): (1) it refers to the proclamation of the eyewitness testimony about the life and ministry of Jesus Christ as proclaimed by the author and the rest of the apostolic witnesses (prologue, esp. 1:3-4), and (2) it relates to the salvation of the hearers/readers, since the purpose of this proclamation is to bring them into fellowship with God and with the apostolic witnesses (1:3). Because of this the adjective “gospel” is included in the English translation.

⁴ tn The referent of the pronoun “him” is not entirely clear in the Greek text; it could be either (1) God the Father, or (2) Jesus Christ, both of whom are mentioned at the end of v. 3. A reference to Jesus Christ is more likely because this is the nearest possible antecedent, and because God (the Father) is specifically mentioned in the following clause in v. 5.

⁵ tn The key to understanding the first major section of 1 John, 1:5-3:10, is found in the statement in v. 5: “God is light and in him there is no darkness at all.” The idea of “proclamation” – the apostolic proclamation of eyewitness testimony which the prologue introduces (1:2, 3) – is picked up in 1:5 by the use of the noun ἀγγελία (angelia) and the verb ἀναγγέλλομεν (anangellomen), cognate to the verb in 1:3. The content of this proclamation is given by the ὅτι (Joti) clause in 1:5 as the assertion that God is light, so this statement should be understood as the author’s formulation of the apostolic eyewitness testimony introduced in the prologue. (This corresponds to the apostolic preaching elsewhere referred to as κήρυγμα [khrugma], although the term the Apostle John uses here is ἀγγελία.)

sn Following the theme statement in 1:5, God is light and in him there is no darkness at all, the author presents a series of three claims and counterclaims that make up the first unit of 1 John (1:5-2:2). The three claims begin with “if” (1:6, 8, 10) and the three counterclaims begin with “but if” (1:7, 9; 2:1).

⁶ 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).

⁷ tn See the note on the first occurrence of “that” in v. 21.

⁸ tn See the note on the first occurrence of “that” in v. 21.

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

¹⁰ sn Everyone who hates his fellow Christian is a murderer. On one level it is easy to see how the author could say this; the person who hates his brother is one and the same with the person who murders his brother. Behind the usage here, however, is John 8:44, the only other occurrence of the Greek word translated murderer (ἀνθρωποκτόνος, anqrwpoktonos) in the NT, where the devil is described as a “murderer from the beginning.” John 8:44 refers to the devil’s role in bringing death to Adam and Eve, but even more to his involvement (not directly mentioned in the Genesis account, but elaborated in the intertestamental literature, especially the writings of Philo) in Cain’s murder of his brother Abel. This was the first incident of murder in human history and also the first outward demonstration of the full implications of sin’s entry into the world. Ultimately, then, the devil is behind murder, just as he was behind Cain’s murder of Abel. When the hater kills, he shows himself to be a child of the devil (cf. 1 John 3:10). Once again, conduct is the clue to paternity.

¹¹ tn The verb μένω (menw) in 3:15 refers to a spiritual reality (eternal life) which in this case does not reside in the person in question. To speak in terms of eternal life not “residing” in such an individual is not to imply that at some time in the past this person did possess eternal life and subsequently lost it, however. The previous verse (3:14) makes it clear that the individual under discussion here has “remained” in death (the realm of spiritual death) and so has never possessed eternal life to begin with, no matter what he may have claimed. Taken together with the use of μένω in 3:14, the use here implies that the opponents have “remained” in death all along, and have not ever been genuine believers. Thus “residing” rather than “remaining” is used as the translation for μένουσαν (menousan) here.

¹² sn An allusion to John 1:18.

¹³ tn The phrase “God resides in us” (ὁ θεὸς ἐν ἡμῖν μένει, Jo qeo" en Jhmin menei) in 4:12 is a reference to the permanent relationship which God has with the believer. Here it refers specifically to God’s indwelling of the believer in the person of the Holy Spirit, as indicated by 4:13b. Since it refers to state and not to change of status it is here translated “resides” (see 2:6).

¹⁴ tn The phrase “his [God’s] love is perfected (τετελειωμένη ἐστίν, teteleiwmenh estin) in us” in 4:12 is difficult. First it is necessary to decide whether αὐτοῦ (autou), which refers to God, is (1) subjective (God’s love for us) or (2) objective (our love for God). It is clear that a subjective genitive, stressing God’s love for us, is in view here, because the immediate context, 4:11a, has believers as the objects of God’s love (ὁ θεὸς ἠγάπησεν ἡμᾶς, Jo qeo" hgaphsen Jhma"). The entire phrase ἡ ἀγάπη αὐτοῦ ἐν ἡμῖν τετελειωμένη ἐστίν (Jh agaph autou en Jhmin teteleiwmenh estin) then refers to what happens when believers love one another (note the protasis of the conditional sentence in 4:12, ἐάν ἀγαπῶμεν ἀλλήλους [ean agapwmen allhlou"]). The love that comes from God, the love that he has for us, reaches perfection in our love for others, which is what God wants and what believers are commanded to do (see 3:23b).
