¹ tn “Some” is not in the Greek text, but is supplied because the prepositional phrase beginning with ἐκ (ek) has partitive force. The partitive force of the prepositional phrase here has been taken by some interpreters to mean that the author has found some of the elect lady’s children who are living according to the truth and some who are not. This is grammatically possible, but the author has merely stated that he knows of some Christians in the church addressed who are “walking in the truth.” He does not know for certain that all of them are, and concern over this is probably part of the motivation for writing the letter.

² sn Living according to the truth (Grk “walking in [the] truth”). The use of the Greek verb περιπατέω (peripatew) to refer to conduct or lifestyle is common in the NT (see 1 John 1:6, 3 John 3-4, as well as numerous times in Paul. Here the phrase refers to conduct that results when a person has “truth” residing within, and possibly alludes to the indwelling Spirit of Truth (see 2 John 2). In the specific context of 2 John the phrase refers to true Christians who are holding fast to an apostolic Christology in the face of the secessionist opponents’ challenge to orthodoxy.

³ tn Grk “just as we received commandment from the Father.” The idiom “we received commandment from the Father” means the Father gave (a) commandment to them (the author plus the recipients).

⁴ tn The construction πᾶς ὁ (pas Jo) + participle occur frequently in 1 John (13 times) where it is used by the author to divide people into categories: “everyone who does this” as opposed to “everyone who does the opposite.”

⁵ tn Here μένω (menw) has been translated “remain” rather than “reside” since a change in status or position is present in the context: The opponents did not “remain” but “ran on ahead.” The verb μένω is used only here (twice in this verse) in the Johannine letters in connection with “teaching” but in the Gospel of John it is used three times with reference to the teaching of Jesus himself (7:16, 17; 18:19).

⁶ tn The genitive τοῦ Χριστοῦ (tou Cristou, “of Christ”) is difficult because it may be understood as objective (the teaching about Christ), subjective (Christ’s own teaching), or both (M. Zerwick’s “general” genitive [Biblical Greek §§36-39]; D. B. Wallace’s “plenary” genitive [ExSyn 119-21]). An objective genitive (with Christ as the object of the “apostolic” teaching) might seem to be the obvious reading in context, especially since verse 7 makes reference to what a person “confesses” about Jesus Christ. A good case can also be made for a subjective genitive, however, since other Johannine uses of the genitive following the noun διδαχή (didach, “teaching”) favor a subjective sense here. In John 7:16, 17 Jesus himself refers to “my teaching” and “teaching from me,” and 18:19 refers to “his (Jesus’) teaching.” Rev 2:14, 15 refers to the “teaching of Balaam” and “the teaching of the Nicolaitans,” both of which are clearly subjective in context. In the present context, to speak of “Christ's teaching” as a subjective genitive would make Christ himself (in the person of the indwelling Spirit) the teacher, and this is consistent with the author’s position in 1 John 2:27 that the community does not need other teachers. In 1 John 2:27 it is the Paraclete, referred to as “his anointing,” who does the teaching. Since the dispute with the opponents concerns the salvific significance of the earthly life and ministry of Jesus, the “teaching” here would refer to Jesus’ own teaching (reflected in the Gospel of John) concerning his person and work. Since this is ultimately one with the apostolic eyewitness testimony about Jesus, it is perhaps best to view the genitive here as both objective and subjective (perhaps the author deliberately intended not to be specific).

⁷ sn The idiom translated have God means to have a relationship to God as a genuine believer. The phrase has both the Father and the Son later in this verse should be understood the same way.
