1 John 1:3

1:3 What we have seen and heard we announce ¹  to you too, so that ²  you may have fellowship ³  with us (and indeed our fellowship is with the Father and with his Son Jesus Christ).

1 John 1:7

1:7 But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses ⁴  us from all sin. ⁵ 

1 John 3:23

3:23 Now ⁶  this is his commandment: ⁷  that we believe in the name of his Son Jesus Christ and love one another, just as he gave ⁸  us the commandment.

1 John 5:20

5:20 And we know that the Son of God has come and has given us insight to know ⁹  him who is true, and we are in him who is true, in his Son Jesus Christ. This one ¹⁰  is the true God and eternal life.

[1:3]  ¹ tn Or “proclaim.”

[1:3]  ² tn The ἵνα (Jina) here indicates purpose.

[1:3]  ³ tn Or “communion”; or “association” (a reality shared in common, so in this case, “genuine association”). This term also occurs in vv. 6, 7.

[1:7]  ⁴ tn Or “purifies.”

[1:7]  ⁵ tn BDAG 50 s.v. ἁμαρτία 1 defines this term as “a departure fr. either human or divine standards of uprightness” (see 1 John 5:17 where ἁμαρτία [Jamartia] and ἀδικία [adikia] are related). This word occurs 17 times in 1 John, of which 11 are singular and 6 are plural.

[3:23]  ⁷ tn The καί (kai) is epexegetical/explanatory (or perhaps resumptive) of the commandment(s) mentioned in the preceding verse.

[3:23]  ⁸ 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.

[3:23]  ⁹ 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.

[5:20]  ¹⁰ 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]  ¹¹ 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.
