1 John 5:20
“We know, too, that the Son of God has come and has given us the power to know the true God. We are in the true God, as we are in his Son, Jesus Christ. This is the true God, this is eternal life.”
According to standard grammatical usage, the demonstrative pronoun houtos (“this”) normally refers to the nearest antecedent within the context. In this case, houtos most naturally points to its immediate referent, Jesus Christ. Consequently, the most direct and coherent reading is Christological:
“Jesus Christ is the true God and eternal life.”
Theological or interpretative considerations may lead some to prefer an alternative reading (for example, referring the pronoun to the Father). However, from a strictly grammatical standpoint, this is not the most natural option.
Furthermore, comparison with other Johannine texts (John 1:14, 18; 20:28) supports the Christological interpretation of 1 John 5:20. In these passages as well, houtos most readily refers to Jesus Christ. This reading is consistent with both the Evangelist’s style and the theological perspective found throughout the Gospel and the Johannine Epistles.
In Johannine literature, “eternal life” is consistently associated with the person of Christ (cf. John 3:15–16; 5:24; 6:47–48; especially 1 John 5:11–12). This further reinforces, on both grammatical and theological grounds, the Christological interpretation of 1 John 5:20.
Therefore, the most coherent reading is:
“houtos (the Son, Jesus Christ) is the true God and eternal life.”
