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 Again, as at the end of 2:27, the verb μένετε (menete) may be read as either (1) indicative or (2) imperative mood. At the end of 2:27 the translation opted for an indicative because the author had been attempting to reassure his readers that they did indeed possess eternal life, and also because an indicative at the end of 2:27 balances the indicative reference to the “anointing” residing in the readers at the beginning of the verse. With the return in 2:28 to the eschatological note introduced in 2:18, however, it appears that the author switches from reassurance to exhortation. At the time he is writing them, the readers do still “remain” since they have not yet adopted the heretical teaching of the opponents. But now the author wants to forestall the possibility that they might do so at some point, and so he begins this section with an exhortation to the readers to “reside/remain” in Christ. This suggests that μένετε in the present verse should be read as imperative rather than indicative, a view made even more probable by the following ἵνα (Jina) clause which states the purpose for the exhortation: in order that at the parousia (second advent) when Jesus Christ is revealed, the readers may have confidence and not shrink back from him in shame when he appears.

⁷ sn A reference to Jesus Christ is more likely here. Note the mention of the second coming (second advent) at the end of this verse.

⁸ tn In this context ἐάν (ean) does not indicate uncertainty about whether or not Christ will return, but rather uncertainty about the exact time when the event will take place. In the Koine period ἐάν could mean “when” or “whenever” and was virtually the equivalent of ὅταν ({otan; see BDAG 268 s.v. ἐάν 2). It has this meaning in John 12:32 and 14:3.

⁹ tn Grk “at his coming.”

sn Have confidence…shrink away from him in shame when he comes back. Once again in the antithetical framework of Johannine thought (that is, the author’s tendency to think in terms of polar opposites), there are only two alternatives, just as there are only two alternatives in John 3:18-21, a key section for the understanding of the present passage in 1 John. Anyone who does not ‘remain’ demonstrates (just as the opponents demonstrated by their departure from the community in 2:19) that whatever profession he has made is false and he is not truly a believer.

¹⁰ tn The καί (kai) is epexegetical/explanatory (or perhaps resumptive) of the commandment(s) mentioned in the preceding verse.

¹¹ tn This verse begins with the phrase καὶ αὕτη ἐστίν (kai {auth estin; cf. the similar phrase in 3:11 and 1:5), which is explained by the following ἵνα (Jina) clause, “that we believe in the name of his Son Jesus Christ.” The ἵνα thus introduces a clause which is (1) epexegetical (explanatory) or (2) appositional. By analogy the similar phrase in 3:11 is also followed by an epexegetical ἵνα clause and the phrase in 1:5 by an epexegetical ὅτι (Joti) clause.

sn His commandment refers to what follows – the commandment from God is to believe in his Son, Jesus Christ, and to love one another.

¹² sn The author of 1 John repeatedly attributes the commandments given to believers as given by God the Father, even though in John 13:34-35 it was Jesus who gave the commandment to love one another. 2 John 4-5 also attributes the commandment to love one another directly to the Father. Thus it is clear that God the Father is the subject of the verb gave here in 3:23.

¹³ tn After a verb of perception (the participle ὁ πιστεύων [Jo pisteuwn]) the ὅτι (Joti) in 5:5 introduces indirect discourse, a declarative or recitative clause giving the content of what the person named by the participle (ὁ πιστεύων) believes: “that Jesus is the Son of God.” As in 4:15, such a confession constitutes a problem for the author’s opponents but not for his readers who are genuine believers.
