² tn The Greek term “brother” can mean “fellow believer” or “fellow Christian” (cf. BDAG 18 s.v. ἀδελφός 2.a) whether male or female. It can also refer to siblings, though here it is used in a broader sense to connote familial relationships within the family of God. Therefore, because of the familial connotations, “brother” has been retained in the translation here in preference to the more generic “fellow believer” (“fellow Christian” would be anachronistic in this context).

¹ sn This verse really explains John 15:10 in another way. Those who keep Jesus’ commandments are called his friends, those friends for whom he lays down his life (v. 13). It is possible to understand this verse as referring to a smaller group within Christianity as a whole, perhaps only the apostles who were present when Jesus spoke these words. Some have supported this by comparing it to the small group of associates and advisers to the Roman Emperor who were called “Friends of the Emperor.” Others would see these words as addressed only to those Christians who as disciples were obedient to Jesus. In either case the result would be to create a sort of “inner circle” of Christians who are more privileged than mere “believers” or average Christians. In context, it seems clear that Jesus’ words must be addressed to all true Christians, not just some narrower category of believers because Jesus’ sacrificial death, which is his act of love toward his friends (v. 13), applies to all Christians equally (cf. John 13:1).

¹ tn The meaning of ἀδικία (adikia) here is “unrighteousness” (BDAG 20 s.v. 2). It refers to the opposite of that which is δίκαιος (dikaios, “right, just, righteous”) which is used by the author to describe both God and Jesus Christ (1 John 1:9; 2:2, 29). Here, having implied that sins committed by believers (sins “not to death”) may be prayed for and forgiven, the author does not want to leave the impression that such sin is insignificant because this could be viewed as a concession to the views of the opponents (who as moral indifferentists have downplayed the significance of sin in the Christian’s life).

² sn From the author’s “either/or” perspective (which tends to see things in terms of polar opposites) the use of a generalization like everyone who presents a way of categorizing the opponents on the one hand and the recipients, whom the author regards as genuine Christians, on the other. Thus everyone who loves refers to all true Christians, who give evidence by their love for one another that they have indeed been begotten by God and are thus God’s children. The opposite situation is described in the following verse, 4:8, where (although everyone [πᾶς, pas] is omitted) it is clear that a contrast is intended.

⁵ tn The closest meaning for σπέρμα (sperma) in this context is “male generating seed” (cf. BDAG 937 s.v. 1.b), although this is a figurative rather than a literal sense. Such imagery is bold and has seemed crudely anthropomorphic to some interpreters, but it poses no more difficulty than the image of God as a male parent fathering Christians that appears in John 1:13 and is behind the use of γεννάω (gennaō) with reference to Christians in 1 John 2:29; 3:9; 4:7; 5:1, 4, and 18.

¹ sn The one who hates his fellow Christian. The author’s paradigm for the opponents portrays them as those who show hatred for fellow Christians (Grk “brothers,” but not referring to one’s physical siblings). This charge will be much more fully developed in chap. 3, where the author will compare the opponents to Cain (who is the model for one who hates a brother, since he ultimately murdered his own brother). In 1 John 3:17 the specific charge against the opponents will be failing to give material aid to a brother in need.

³ sn No prophecy of scripture ever comes about by the prophet’s own imagination. 2 Pet 1:20-21, then, form an inclusio with v. 16: The Christian’s faith and hope are not based on cleverly concocted fables but on the sure Word of God—one which the prophets, prompted by the Spirit of God, spoke. Peter’s point is the same as is found elsewhere in the NT, i.e., that human prophets did not originate the message, but they did convey it, using their own personalities in the process.

¹ sn Do not give him any greeting does not mean to insult the person. It means “do not greet the person as a fellow Christian” (which is impossible anyway since the opponents are not genuine believers in the author’s opinion).

¹ tn The preposition ἐκ (ek) here indicates both source and possession: Christians are “from” God in the sense that they are begotten by him, and they belong to him. For a similar use of the preposition compare the phrases ἐκ τοῦ πατρός (ek tou patros) and ἐκ τοῦ κόσμου (ek tou kosmou) in 1 John 2:16.

¹ sn The one who practices righteousness. The participle (ὁ ποιῶν, ho poiōn) + noun constructions in 3:7 and in 3:8a, the first positive and the second negative, serve to emphasize the contrast between the true Christians (“the one who practices righteousness”) and the opponents (“the one who practices sin,” 3:8a).

¹ tn Grk “brothers,” but the Greek word may be used for “brothers and sisters” or “fellow Christians” as here (cf. BDAG 18 s.v. ἀδελφός 1., where considerable nonbiblical evidence for the plural ἀδελφοί [adelphoi] meaning “brothers and sisters” is cited).

³ tn Grk “in the Diaspora.” The Greek term διασπορά (diaspora, “dispersion”) refers to Jews not living in Palestine but “dispersed” or scattered among the Gentiles. But here it is probably metaphorical, used of Gentile Christians spread out as God’s people in the midst of a godless world.

² tn Grk “synagogue.” Usually συναγωγή refers to Jewish places of worship (e.g., Matt 4:23, Mark 1:21, Luke 4:15, John 6:59). The word can be used generally to refer to a place of assembly, and here it refers specifically to a Christian assembly (BDAG 963 s.v. 2.b.).

¹ tn Grk “brothers,” but the Greek word may be used for “brothers and sisters” or “fellow Christians” as here (cf. BDAG 18 s.v. ἀδελφός 1, where considerable nonbiblical evidence for the plural ἀδελφοί [adelphoi] meaning “brothers and sisters” is cited).

¹ tn The article τῆς (tēs) has been translated as a possessive pronoun, “your” (ExSyn 215). It may also be functioning to indicate a well-known concept (inheritance as eternal life). See BDAG 548 s.v. κληρονομία 3: “common in Christian usage (corresp. to the LXX) (the possession of) transcendent salvation (as the inheritance of God’s children).”

² sn Paul’s point is that even though the arguments seem to make sense (sound reasonable), they are in the end false. Paul is not here arguing against the study of philosophy or serious thinking per se, but is arguing against the uncritical adoption of a philosophy that is at odds with a proper view of Christ and the ethics of the Christian life.

² tn Grk “brothers,” but the Greek word may be used for “brothers and sisters” or “fellow Christians” as here (cf. BDAG 18 s.v. ἀδελφός 1, where considerable nonbiblical evidence for the plural ἀδελφοί [adelphoi] meaning “brothers and sisters” is cited).
