¹ tn See note on the translation of the Greek verb μένω (menw) in 2:6. Here μένω has been translated as “remained” since it is clear that a change of status or position is involved. The opponents departed from the author’s congregation(s) and showed by this departure that they never really belonged. Had they really belonged, they would have stayed (“remained”).

² tn Because of the length and complexity of the Greek sentence, a new sentence was started here in the translation.

³ tn The phrase “they went out from us” is not repeated a second time in the Greek text, but constitutes an ellipsis. For clarity it is necessary to repeat it in the English translation.

⁴ tn Grk “in order that it may be demonstrated.” The passive infinitive has been translated as active and the purpose clause translated by an infinitive in keeping with contemporary English style.

⁵ sn All of them do not belong to us. The opponents chose to depart rather than remain in fellowship with the community to which the author writes and with which he associates himself. This demonstrates conclusively to the author that they never really belonged to that community at all (in spite of what they were claiming). 1 John 2:19 indicates that the departure was apparently the opponents’ own decision rather than being thrown out or excommunicated. But for John, if they had been genuine believers, they would have remained in fellowship. Now they have gone out into the world, where they belong (compare 1 John 4:5).

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.
