[5:2]  ¹ tn Once more there is the familiar difficulty of determining whether the phrase refers (1) to what precedes or (2) to what follows. Here, because ἐν τούτῳ (en toutw) is followed by a clause introduced by ὅταν (Jotan) which appears to be related, it is best to understand ἐν τούτῳ as referring to what follows. The following ὅταν clause is epexegetical to ἐν τούτῳ, explaining how we know that we love God’s children: “by this we know that we love God’s children, whenever we love God and keep his commandments.”

[3:11]  ² tn It could be argued (1) that the ὅτι (Joti) at the beginning of 3:11 is grammatically subordinate to the preceding statement at the end of 3:10. As BDF §456.1 points out, however, “Subordination with ὅτι and διότι is often very loose…and must be translated ‘for.’” Thus (2) ὅτι assumes an inferential sense, standing at the beginning of a new sentence and drawing an inference based upon all that has preceded. This is confirmed by the structural parallel between the present verse and 1:5.

[3:11]  ³ tn The word “gospel” is not in the Greek text but is supplied to clarify the meaning. See the notes on the words “gospel” and “message” in 1 John 1:5.

[3:11]  ⁴ tn See the note on the word “message” in 1 John 1:5, where this same phrase occurs.

[3:11]  ⁵ sn For this is the gospel message…that we should love one another. The structure of this verse is parallel to 1:5, indicating the beginning of a second major section of the letter.

[3:18]  ³ sn The noun truth here has been interpreted in various ways: (1) There are a number of interpreters who understand the final noun in this series, truth (ἀληθείᾳ, alhqeia) in an adverbial sense (“truly” or “in sincerity”), describing the way in which believers are to love. If the two pairs of nouns are compared, however, it is hard to see how the second noun with tongue (γλώσσῃ, glwssh) in the first pair can have an adverbial sense. (2) It seems better to understand the first noun in each pair as produced by the second noun: Words are produced by the tongue, and the (righteous) deeds with which believers are to love one another are produced by the truth.

[4:19]  ⁴ sn No object is supplied for the verb love (the author with his propensity for obscurity has left it to the readers to supply the object). The obvious objects that could be supplied from the context are either God himself or other believers (the brethren). It may well be that the author has both in mind at this point; the statement is general enough to cover both alternatives, although the following verse puts more emphasis on love for the brethren.

[3:14]  ⁵ tn The first ὅτι (Joti) clause, following a verb of perception, introduces an indirect discourse clause giving the content of what the readers are assumed to know: that they have passed over from death to life, that is, that they possess eternal life. The author gives a similar reassurance to his readers in 5:13. Alternation between the verbs οἶδα (oida) and γινώσκω (ginwskw) in 1 John is probably a matter of stylistic variation (of which the writer is extremely fond) rather than indicative of a subtle difference in meaning.

[3:14]  ⁶ tn This verb essentially means “to transfer from one place to another, go/pass over,” according to BDAG 638 s.v. μεταβαίνω 1.

[3:14]  ⁷ sn Cf. John 5:24, where this phrase also occurs.

[3:14]  ⁸ tn The second ὅτι (Joti) clause in 3:14 is also related to οἴδαμεν (oidamen), but in this case the ὅτι is causal, giving the reason why the readers know that they have passed from death to life: because they love the brothers.

[3:14]  ⁹ tn See note on the phrase “fellow Christian” in 2:9.

[3:14]  ¹⁰ sn The one who does not love remains in death. Again, the author has the secessionist opponents in view. Their refusal to show love for the brothers demonstrates that they have not made the transition from (spiritual) death to (spiritual) life, but instead have remained in a state of (spiritual) death.

[4:12]  ⁶ sn An allusion to John 1:18.

[4:12]  ⁷ 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).

[4:12]  ⁸ 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).
