1 John 5:1

5:1 Everyone who believes that Jesus is the Christ ¹  has been fathered ²  by God, and everyone who loves the father ³  loves the child fathered by him. ⁴ 

1 John 5:20

5:20 And we know that the Son of God has come and has given us insight to know ⁵  him who is true, and we are in him who is true, in his Son Jesus Christ. This one ⁶  is the true God and eternal life.

[5:1]  ¹ tn Or “the Messiah.”

[5:1]  ² 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.

[5:1]  ³ 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.

[5:1]  ⁴ 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.

[5:20]  ⁵ tn The ἵνα (Jina) introduces a purpose clause which gives the purpose of the preceding affirmation: “we know that the Son of God has come and has given us insight (so that we may) know him who is true.”

[5:20]  ⁶ sn The pronoun This one (οὗτος, Joutos) refers to a person, but it is far from clear whether it should be understood as a reference (1) to God the Father or (2) to Jesus Christ. R. E. Brown (Epistles of John [AB], 625) comments, “I John, which began with an example of stunning grammatical obscurity in the prologue, continues to the end to offer us examples of unclear grammar.” The nearest previous antecedent is Jesus Christ, immediately preceding, but on some occasions when this has been true the pronoun still refers to God (see 1 John 2:3). The first predicate which follows This one in 5:20, the true God, is a description of God the Father used by Jesus in John 17:3, and was used in the preceding clause of the present verse to refer to God the Father (him who is true). Yet the second predicate of This one in 5:20, eternal life, appears to refer to Jesus, because although the Father possesses “life” (John 5:26, 6:57) just as Jesus does (John 1:4, 6:57, 1 John 5:11), “life” is never predicated of the Father elsewhere, while it is predicated of Jesus in John 11:25 and 14:6 (a self-predication by Jesus). If This one in 5:20 is understood as referring to Jesus, it forms an inclusion with the prologue, which introduced the reader to “the eternal life which was with the Father and was manifested to us.” Thus it appears best to understand the pronoun This one in 5:20 as a reference to Jesus Christ. The christological affirmation which results is striking, but certainly not beyond the capabilities of the author (see John 1:1 and 20:28): This One [Jesus Christ] is the true God and eternal life.
