1 John 5:18
5:18 We know that everyone fathered 1 by God does not sin, but God 2 protects 3 the one he has fathered, and the evil one cannot touch him.
1 John 5:21
5:21 Little children, guard yourselves from idols. 4
1 tn The concept represented by the verb γεννάω (gennaw) here means to be fathered by God and thus a child of God. The imagery in 1 John is that of the male parent who fathers children (see 2:29).
2 tn Grk “he”; see the note on the following word “protects.”
3 tn The meaning of the phrase ὁ γεννηθεὶς ἐκ τοῦ θεοῦ τηρεῖ αὐτόν (Jo gennhqeis ek tou qeou threi auton) in 5:18 is extraordinarily difficult. Again the author’s capacity for making obscure statements results in several possible meanings for this phrase: (1) “The fathering by God protects him [the Christian].” Here a textual variant for ὁ γεννηθείς (ἡ γέννησις, Jh gennhsi") has suggested to some that the passive participle should be understood as a noun (“fathering” or perhaps “birth”), but the ms evidence is extremely slight (1505 1852 2138 latt [syh] bo). This almost certainly represents a scribal attempt to clarify an obscure phrase. (2) “The One fathered by God [Jesus] protects him [the Christian].” This is a popular interpretation, and is certainly possible grammatically. Yet the introduction of a reference to Jesus in this context is sudden; to be unambiguous the author could have mentioned the “Son of God” here, or used the pronoun ἐκεῖνος (ekeinos) as a reference to Jesus as he consistently does elsewhere in 1 John. This interpretation, while possible, seems in context highly unlikely. (3) “The one fathered by God [the Christian] protects himself.” Again a textual problem is behind this alternative, since a number of mss (א Ac P Ψ 33 1739 Ï) supply the reflexive pronoun ἑαυτόν (Jeauton) in place of αὐτόν in 5:18. On the basis of the external evidence this has a good possibility of being the original reading, but internal evidence favors αὐτόν as the more difficult reading, since ἑαυτόν may be explained as a scribal attempt at grammatical smoothness. From a logical standpoint, however, it is difficult to make much more sense out of ἑαυτόν; to say what “the Christian protects himself” means in the context is far from clear. (4) “The one fathered by God [the Christian] holds on to him [God].” This results in further awkwardness, because the third person pronoun (αὐτοῦ, autou) in the following clause must refer to the Christian, not God. Furthermore, although τηρέω (threw) can mean “hold on to” (BDAG 1002 s.v. 2.c), this is not a common meaning for the verb in Johannine usage, occurring elsewhere only in Rev 3:3. (5) “The one fathered by God [the Christian], he [God] protects him [the Christian].” This involves a pendant nominative construction (ὁ γεννηθεὶς ἐκ τοῦ θεοῦ) where a description of something within the clause is placed in the nominative case and moved forward ahead of the clause for emphatic reasons. This may be influenced by Semitic style; such a construction is also present in John 17:2 (“in order that everyone whom You have given to him, he may give to them eternal life”). This view is defended by K. Beyer (Semitische Syntax im Neuen Testament [SUNT], 1:216ff.) and appears to be the most probable in terms both of syntax and of sense. It makes God the protector of the Christian (rather than the Christian himself), which fits the context much better, and there is precedent in Johannine literature for such syntactical structure.
4 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.
sn The modern reader may wonder what all this has to do with idolatry. In the author’s mind, to follow the secessionist opponents with their false Christology would amount to idolatry, since it would involve worshiping a false god instead of the true God, Jesus Christ. Thus guard yourselves from idols means for the readers to guard themselves against the opponents and their teaching.
