2 Corinthians 11:3
2 Corinthians 11:33I am afraid, however, that just as Eve was deceived by the serpent’s cunning, your minds may be led astray from your simple and pure devotion to Christ.
JWs invoke ("the serpent seduced Eve by its cunning... your minds might be corrupted away from the sincerity and the chastity that are due the Christ") as a warning against deception by "apostate" teachings and independent Bible study. The "sincerity that is due the Christ" is understood as unified submission to the organisation's interpretation — deviation from which is framed as Satan-orchestrated corruption of the mind.
Paul's actual fear is something quite different — and quite specific. What Paul worries will be corrupted is the simplicity (ESV/NIV) or sincerity (NWT) that belongs to Christ. The gospel is plain: Christ crucified for sinners, righteousness received through faith (), salvation as a completed perfect- tense gift ("you have been saved" — , NWT). When anything is added to that simplicity, it is corrupted.
The NWT's rendering of pisteuō as "exercise faith" throughout , , and elsewhere is exactly the corruption Paul warns about — a stative verb ("believe") converted to an ongoing effort ("keep exercising"), adding a works-component to what Paul calls simplicity. Ray Comfort's parachute analogy puts it bluntly: a parachute plus arm-flapping is not "mostly parachute"; it is distrust of the parachute. warns against the very drift JWs are trained to make — trust Christ plus obey the organisation — because Christ plus anything is Christ zero.
