¹ tn Or “the Messiah”

² tn The καί (kai) is epexegetical/explanatory (or perhaps resumptive) of the commandment(s) mentioned in the preceding verse.

³ tn This verse begins with the phrase καὶ αὕτη ἐστίν (kai {auth estin; cf. the similar phrase in 3:11 and 1:5), which is explained by the following ἵνα (Jina) clause, “that we believe in the name of his Son Jesus Christ.” The ἵνα thus introduces a clause which is (1) epexegetical (explanatory) or (2) appositional. By analogy the similar phrase in 3:11 is also followed by an epexegetical ἵνα clause and the phrase in 1:5 by an epexegetical ὅτι (Joti) clause.

sn His commandment refers to what follows – the commandment from God is to believe in his Son, Jesus Christ, and to love one another.

⁴ sn The author of 1 John repeatedly attributes the commandments given to believers as given by God the Father, even though in John 13:34-35 it was Jesus who gave the commandment to love one another. 2 John 4-5 also attributes the commandment to love one another directly to the Father. Thus it is clear that God the Father is the subject of the verb gave here in 3:23.

⁵ tn There is no subordinating conjunction following the ἐν τούτῳ (en toutw) here in 4:2, so the phrase could refer either (1) to what precedes or (2) to what follows. Contextually the phrase refers to what follows, because the following clause in 4:2b-3a (πᾶν πνεῦμα ὃ ὁμολογεῖ ᾿Ιησοῦν Χριστὸν…ἐκ τοῦ θεοῦ ἐστιν, καὶ πᾶν πνεῦμα ὃ μὴ ὁμολογεῖ τὸν ᾿Ιησοῦν ἐκ τοῦ θεοῦ οὐκ ἔστιν), while not introduced by a subordinating conjunction, does explain the preceding clause beginning with ἐν τούτῳ. In other words, the following clause in 4:2b-3a is analogous to a subordinate clause introduced by an epexegetical ἵνα (Jina) or ὅτι (Joti), and the relationship can be represented in the English translation by a colon, “By this you know the Spirit of God: Every Spirit that confesses Jesus as the Christ who has come in the flesh is from God, but every Spirit that does not confess Jesus is not from God.”

⁶ tn Or “acknowledges.”

⁷ tn This forms part of the author’s christological confession which serves as a test of the spirits. Many interpreters have speculated that the author of 1 John is here correcting or adapting a slogan of the secessionist opponents, but there is no concrete evidence for this in the text. Such a possibility is mere conjecture (see R. E. Brown, Epistles of John [AB], 492). The phrase may be understood in a number of different ways, however: (1) the entire phrase “Jesus Christ come in the flesh” may be considered the single object of the verb ὁμολογεῖ (Jomologei; so B. F. Westcott, A. Brooke, J. Bonsirven, R. E. Brown, S. Smalley, and others); (2) the verb ὁμολογεῖ may be followed by a double accusative, so that both “Jesus Christ” and “come in the flesh” are objects of the verb; the meaning would be “confess Jesus Christ as come in the flesh” (so B. Weiss, J. Chaine, and others). (3) Another possibility is to see the verb as followed by a double accusative as in (2), but in this case the first object is “Jesus” and the second is “the Christ come in the flesh,” so that what is being confessed is “Jesus as the Christ come in the flesh” (so N. Alexander, J. Stott, J. Houlden, and others). All three options are grammatically possible, although not equally probable. Option (1) has a number of points in its favor: (a) the parallel in 2 John 7 suggests to some that the phrase should be understood as a single object; (b) option (2) makes “Jesus Christ” the name of the preincarnate second Person of the Trinity, and this would be the only place in the Johannine literature where such a designation for the preincarnate Λόγος (Logos) occurs; and (c) option (3) would have been much clearer if Χριστόν (Criston) were accompanied by the article (ὁμολογεῖ ᾿Ιησοῦν τὸν Χριστόν, Jomologei Ihsoun ton Criston). Nevertheless option (3) is preferred on the basis of the overall context involving the secessionist opponents: Their christological views would allow the confession of the Christ come in the flesh (perhaps in the sense of the Spirit indwelling believers, although this is hard to prove), but they would have trouble confessing that Jesus was (exclusively) the Christ incarnate. The author’s failure to repeat the qualifying phrases (Χριστὸν ἐν σαρκὶ ἐληλυθότα, Criston en sarki elhluqota) in the negative repetition in 4:3a actually suggests that the stress is on Jesus as the confession the opponents could not or would not make. It is difficult to see how the parallel in 2 John 7 favors option (1), although R. E. Brown (Epistles of John [AB], 492) thinks it does. The related or parallel construction in John 9:22 (ἐάν τις αὐτὸν ὁμολογήσῃ Χριστόν, ean ti" auton Jomologhsh Criston) provides further support for option (3). This is discounted by R. E. Brown because the verb in John 9:22 occurs between the two accusative objects rather than preceding both as here (Epistles of John [AB], 493 – although Brown does mention Rom 10:9 as another parallel closer in grammatical structure to 1 John 4:2). Brown does not mention the textual variants in John 9:22, however: Both Ì⁶⁶ and Ì⁷⁵ (along with K, ˹³ and others) read ὁμολογήσῃ αὐτὸν Χριστόν (Jomologhsh auton Criston). This structure exactly parallels 1 John 4:2, and a case can be made that this is actually the preferred reading in John 9:22; furthermore, it is clear from the context in John 9:22 that Χριστόν is the complement (what is predicated of the first accusative) since the object (the first accusative) is αὐτόν rather than the proper name ᾿Ιησοῦν. The parallel in John 9:22 thus appears to be clearer than either 1 John 4:2 or 2 John 7, and thus to prove useful in understanding both the latter constructions.

⁸ tn Or “the Messiah.”

⁹ tn 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 the note on “fathered” in 2:29 for further discussion of this imagery.

¹⁰ tc ‡ Most witnesses ([א] A P 1739 Ï sy) have καί (kai, “also”) before the article τόν (ton). But the external evidence for the shorter reading is significant (B Ψ 048^vid 33 pc sa), and the conjunction looks to be a motivated reading in which scribes emulated the wording of 4:21 (ἀγαπᾷ καὶ τόν, agapa kai ton). NA²⁷ places the conjunction in brackets, indicating doubts as to its authenticity.

¹¹ sn Also loves the child fathered by him. Is the meaning of 5:1b a general observation or a specific statement about God and Christians? There are three ways in which the second half of 5:1 has been understood: (1) as a general statement, proverbial in nature, applying to any parent: “everyone who loves the father also loves the child fathered by him.” (2) This has also been understood as a statement that is particularly true of one’s own parent: “everyone who loves his own father also loves the (other) children fathered by him (i.e., one’s own brothers and sisters).” (3) This could be understood as a statement which refers particularly to God, in light of the context (5:1a): “everyone who loves God who fathered Christians also loves the Christians who are fathered by God.” Without doubt options (2) and (3) are implications of the statement in its present context, but it seems most probable that the meaning of the statement is more general and proverbial in nature (option 1). This is likely because of the way in which it is introduced by the author with πᾶς ὁ (pas Jo) + participle. The author could have been more explicit and said something like, “everyone who loves God also loves God’s children” had he intended option (3) without ambiguity. Yet that, in context, is the ultimate application of the statement, because it ultimately refers to the true Christian who, because he loves God, also loves the brethren, those who are God’s offspring. This is the opposite of 4:20, where the author asserted that the opponents, who profess to love God but do not love the brethren, cannot really love God because they do not love the brethren.
