¹ tc Most later mss (P Ï) have ἀμήν (amhn, “amen”) at the end of this letter. Such a conclusion is routinely added by scribes to NT books because a few of these books originally had such an ending (cf. Rom 16:27; Gal 6:18; Jude 25). A majority of Greek witnesses have the concluding ἀμήν in every NT book except Acts, James, and 3 John (and even in these books, ἀμήν is found in some witnesses). It is thus a predictable variant. Further, the earliest and best witnesses, along with several others (א A B Ψ 33 323 630 1505 1739 al sy co), lack the inoffensive particle, rendering its omission as the authentic reading.

² tc πάντες (pantes, nominative plural in “you all know”) is read by א B P Ψ sa. A C 049 33 1739 Ï latt sy bo have the accusative πάντα (panta, “you know all things”). The evidence favors the nominative reading, but it is not overwhelming. At the same time, the internal evidence supports the nominative for a variety of reasons. A scribe would naturally tend to give the transitive verb a direct object, especially because of the parallel in the first half of the verse. And intrinsically, the argument seems to be in balance with v. 19: The “all” who have gone out and are not “in the know” with the “all” who have an anointing and know that they are true believers. Further, as R. E. Brown points out, “the fact of their knowledge (pantes), not the extent of its object (panta), seems best to fit the reassurance” (Epistles of John [AB], 349). Brown further points out the connection with the new covenant in Jer 31 with this section of 1 John, esp. Jer 31:34 – “they all [pantes] shall know me.” Since 1 John alludes to Jer 31, without directly quoting it, this is all the more reason to see the nominative as original: Allusions are often overlooked by scribes (transcriptional evidence), but support the intrinsic evidence. Thus, the evidence is solidly (though not overwhelmingly) behind the nominative reading.

³ tn Or “just.”

⁴ tn The ἵνα (Jina) followed by the subjunctive is here equivalent to the infinitive of result, an “ecbatic” or consecutive use of ἵνα according to BDAG 477 s.v. 3 where 1 John 1:9 is listed as a specific example. The translation with participles (“forgiving, …cleansing”) conveys this idea of result.

⁵ tn Or “purifying.”

⁴ tn Or “purifies.”

⁵ tn BDAG 50 s.v. ἁμαρτία 1 defines this term as “a departure fr. either human or divine standards of uprightness” (see 1 John 5:17 where ἁμαρτία [Jamartia] and ἀδικία [adikia] are related). This word occurs 17 times in 1 John, of which 11 are singular and 6 are plural.
