¹ sn Everyone who practices sin. In contrast to the πᾶς ὁ (pas Jo) + participle construction in 3:3 (everyone who has, πᾶς ὁ ἔχων [pas Jo ecwn]) which referred to believers, the use of everyone who practices sin (πᾶς ὁ ποιῶν τὴν ἁμαρτίαν [pas Jo poiwn thn Jamartian]) here refers to the author’s opponents. A similar use, referring to the opponents’ denial of the Son, is found in 2:23.

² sn The Greek word ἀνομία (anomia) is often translated “iniquity” or “lawlessness” and in the LXX refers particularly to transgression of the law of Moses. In Jewish thought the ideas of sin (ἁμαρτία, Jamartia) and lawlessness or iniquity (ἀνομία) were often equated because sin involved a violation of the Mosaic law and hence lawlessness. For example, Ps 51:5 LXX sets the two in parallel, and Paul in Rom 4:7 (quoting Ps 32:1) does the same. For the author, it is not violation of the Mosaic law that results in lawlessness, since he is writing to Christians. The ‘law’ for the author is the law of love, as given by Jesus in the new commandment of John 13:34-35. This is the command to love one’s brother, a major theme of 1 John and the one specific sin in the entire letter which the opponents are charged with (3:17). Since the author has already labeled the opponents “antichrists” in 2:18, it may well be that he sees in their iniquitous behavior of withdrawing from the community and refusing to love the brethren a foreshadowing of the apocalyptic iniquity of the end times (cf. 2 Thess 2:3-8). In Matt 24:11-12 Jesus foretold that false prophets would arise in the end times (cf. 1 John 4:1), that lawlessness (anomia) would increase, and that “the love of many will grow cold” (which would certainly fit the author’s portrait of the opponents here).

³ tn Grk “and.”

⁴ sn The person who practices sin is of the devil. 1 John 3:10 and John 8:44 might be cited as parallels, because these speak of opponents as the devil’s “children.” However, it is significant that the author of 1 John never speaks of the opponents as “fathered by the devil” in the same sense as Christians are “fathered by God” (3:9). A concept of evildoers as “fathered” by the devil in the same sense as Christians are fathered by God would imply a much more fully developed Gnosticism with its dualistic approach to humanity. The author of 1 John carefully avoids saying that the opponents are “fathered by the devil,” because in Johannine theology not to be fathered by God is to be fathered only by the flesh (John 1:13). This is a significant piece of evidence that 1 John predates the more fully developed Gnosticism of the 2nd century. What the author does say is that the opponents (“the one who practices sin”) are from the devil, in the sense that they belong to him and have given him their allegiance.

⁵ tn The present tense verb has been translated as an extending-from-past present (a present of past action still in progress). See ExSyn 520.

⁶ tn Here εἰς τοῦτο (eis touto) states the purpose for the revelation of God’s Son. However, the phrase offers the same difficulty as all the ἐν τούτῳ (en toutw) phrases in 1 John: Does it refer to what precedes or to what follows? By analogy with the ἐν τούτῳ construction it is probable that the phrase εἰς τοῦτο here refers to what follows: There is a ἵνα (Jina) clause following which appears to be related to the εἰς τοῦτο, and in fact is resumptive (that is, it restates the idea of “purpose” already expressed by the εἰς τοῦτο). Thus the meaning is: “For this purpose the Son of God was revealed: to destroy the works of the devil.”

⁷ tn In the Gospel of John λύσῃ (lush) is used both literally and figuratively. In John 1:27 it refers to a literal loosing of one’s sandal-thong, and in John 2:19 to a destruction of Jesus’ physical body which was understood by the hearers to refer to physical destruction of the Jerusalem temple. In John 5:18 it refers to the breaking of the Sabbath, in John 7:23 to the breaking of the law of Moses, and in John 10:35 to the breaking of the scriptures. The verb is again used literally in John 11:44 at the resurrection of Lazarus when Jesus commands that he be released from the graveclothes with which he was bound. Here in 1 John 3:8 the verb means, with reference to “the works of the devil,” to “destroy, bring to an end, abolish.” See BDAG 607 s.v. λύω 4 and F. Büchsel, TDNT 4:336.
