Romans 6:6
Romans 6:66We know that our old self was crucified with Him so that the body of sin might be rendered powerless, that we should no longer be slaves to sin.
JWs read as describing the believer's break with the former corrupt personality through Christ's sacrifice — applied pastorally to the brother fighting compulsive sin, often paired with the expectation that visible behaviour change should follow the union with Christ as evidence of the spirit's operation.
Paul's logic is union-with-Christ-as-the-ground-of-mortification. The old self was crucified with Christ; the body of sin is rendered powerless; the believer is no longer enslaved to sin. This is Paul's theological architecture for the rescue of the brother fighting pornography — UNION first (v. 6 — old self crucified), then mortification by the Spirit ( — "if by the Spirit you put to death the deeds of the body, you will live"), inside a fellowship of mutual confession (). The Watchtower's tribunal-and-classification model interrupts that architecture by making confession institutionally costly — the brother fights alone in shame, with the rescue mechanism scripture prescribes locked behind a judicial committee door.
The NWT 2013 renders palaios anthropos as "old personality" — distinctive of the NWT and consistent with its psychological rather than theological framing of conversion. Standard translations (BSB, ESV, NASB) render "old self"; KJV "old man". The "personality" rendering shifts the metaphor from the representative-headship language Paul uses (Adam vs Christ) toward modern psychological vocabulary, which can soften the judicial- representative dimension of union with Christ. The NWT also renders stauros as "stake" rather than "cross" — a translation consistent with Watchtower teaching that Jesus died on an upright pole rather than a traditional cross-shaped instrument; this is not exegetically forced by the Greek but is a Watchtower distinctive.
