¹ tn The translation of καί (kai) at the beginning of 2:3 is important for understanding the argument, because a similar καί occurs at the beginning of 1:5. The use here is not just a simple continuative or connective use, but has more of a resumptive force, pointing back to the previous use in 1:5.

sn Now. The author, after discussing three claims of the opponents in 1:6, 8, and 10 and putting forward three counterclaims of his own in 1:7, 1:9, and 2:1, now returns to the theme of “God as light” introduced in 1:5. The author will now discuss how a Christian may have assurance that he or she has come to know the God who is light, again by contrast with the opponents who make the same profession of knowing God, but lack the reality of such knowledge, as their behavior makes clear.

² tn Grk “know him.” (1) Many take the third person pronoun αὐτον (auton) to refer to Jesus Christ, since he is mentioned in 2:1 and the pronoun αὐτός (autos) at the beginning of 2:2 clearly refers to him. But (2) it is more likely that God is the referent here, since (a) the assurance the author is discussing here is assurance that one has come to know God (all the claims of the opponents in 1:5-2:11 concern knowing and having fellowship with the God who is light); (b) when Jesus Christ is explicitly mentioned as an example to follow in 1 John 2:6, the pronoun ἐκεῖνος (ekeinos) is used to distinguish this from previous references with αὐτός; (c) the καί (kai) which begins 2:3 is parallel to the καί which begins 1:5, suggesting that the author is now returning to the discussion of God who is light, a theme introduced in 1:5. The author will now discuss how a Christian may have assurance that he or she has come to know the God who is light.

³ sn I am writing to you. The author appears to have been concerned that some of his readers, at least, would accept the claims of the opponents as voiced in 1:6, 8, and 10. The counterclaims the author has made in 1:7, 9, and 2:1 seem intended to strengthen the readers and reassure them (among other things) that their sins are forgiven. Further assurances of their position here is in keeping with such a theme, and indeed, the topic of reassurance runs throughout the entire letter (see the purpose statement in 5:13). Finally, in such a context the warning which follows in 2:15-17 is not out of place because the author is dealing with a community that is discouraged by the controversy which has arisen within it and that is in need of exhortation.

⁴ tn The ὅτι (Joti) that follows all six occurrences of γράφω/ἔγραψα (grafw/egraya) in 2:12-14 can be understood as introducing either (1) a causal clause or (2) a content clause (if content, it could be said to introduce a direct object clause or an indirect discourse clause). Many interpreters have favored a causal translation, so that in each of the six cases what follows the ὅτι gives the reason why the author is writing to the recipients. Usage in similar constructions is not decisive because only one other instance of γράφω followed by ὅτι occurs in 1 John (2:21), and that context is just as ambiguous as this one. On other occasions γράφω does tend to be followed by a noun or pronoun functioning as direct object. This might argue for the content usage here, but it could also be argued that the direct object in the six instances in these verses is understood, namely, the content of the entire letter itself. Thus the following ὅτι clause could still be causal. Grammatical considerations aside, these uses of ὅτι are more likely introducing content clauses here rather than causal clauses because such a meaning better fits the context. If the uses of ὅτι are understood as causal, it is difficult to see why the author immediately gives a warning in the section that follows about loving the world. The confidence he has expressed in his readers (if the ὅτι clauses are understood as causal) would appear to be ill-founded if he is so concerned about their relationship to the world as 2:15-17 seems to indicate. On the other hand, understanding the ὅτι clauses as content clauses fits very well the context of reassurance which runs throughout the letter.

⁵ tn “His” probably refers to Jesus Christ. Note the last reference was to Jesus in 2:8 and before that in 2:6; also the mention of sins being forgiven suggests Jesus’ work on the cross.

⁶ 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.

⁷ 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.

⁸ tn See the note on the word “message” in 1 John 1:5, where this same phrase occurs.

⁹ 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.

¹⁰ tn Because σωτῆρα (swthra) is the object complement of υἱόν (Juion) in a double accusative construction in 4:14, there is an understood equative verb joining the two, with the resultant meaning “the Father sent the Son to be the Savior of the world.”
