John 14:10
John 14:1010Do you not believe that I am in the Father and the Father is in Me? The words I say to you, I do not speak on My own. Instead, it is the Father dwelling in Me, performing His works.
Read as relational unity — Jesus is "in union with" the Father in the same way believers are "in union with" Christ (). The language is downgraded from ontological mutual indwelling to a shared- purpose relationship. The Watchtower's NWT itself does the downgrading by inserting "in union with" wherever the Greek says simply "in."
The Greek preposition is the simple en — "in." Jesus is "in" the Father, the Father is "in" Jesus. That mutual indwelling — what later theology calls perichoresis — is unique to the persons of the Trinity. Pair with ("the Father is in me, and I am in the Father") and ("all the fullness of the divine quality dwells bodily"). The believer's "abiding in" Christ (John 15) is real and important, but it is not the same kind of mutual indwelling Jesus describes between himself and the Father. Jesus does the works of the Father; the Father does works in and through the Son. That is a unity no creature can claim.
Where the Greek reads simply "in the Father" (ἐν τῷ πατρί) and "in me" (ἐν ἐμοί), the NWT renders "in union with the Father" / "in union with me." The phrase "in union with" is a paraphrase consistently inserted across John's gospel and Paul's letters wherever the simple "in [Christ/Father]" formula appears. The cumulative effect is to dissolve the New Testament's mutual-indwelling language into a weaker relational-union vocabulary that fits a JW Christology in which the Father and Son are not ontologically one. The "remains" language at the end of the verse — "the Father who remains in union with me is doing his works" — is the same expansion.
