Verse explainer
One of the Bible's most debated verses — Paul isn't endorsing a ritual, he's making a logical point: if there's no resurrection, why would anyone be baptized in hope of it?
Else what shall they do which are baptized for the dead, if the dead rise not at all? why are they then baptized for the dead?
BSBIf these things are not so, what will those do who are baptized for the dead? If the dead are not raised at all, why are people baptized for them?
The plain meaning
Paul is in the middle of a sustained argument for the resurrection of the dead (ch. 15). His point in v. 29 is rhetorical: he's pointing to a practice — whatever exactly it was — as evidence that even those doing it implicitly assumed a resurrection. His logic runs, "If the dead don't rise, then this practice makes no sense at all." The verse is sandwiched between a list of Paul's own sufferings for the gospel (vv. 30-32) and a warning against those who say there is no resurrection (v. 34). Paul is not ordaining or endorsing any practice here; he's using an ad hominem argument — meeting opponents on their own ground to expose the inconsistency of denying the resurrection while still performing rites that only make sense if the resurrection is real. The surrounding chapter is a masterclass in resurrection theology: Christ rose (vv. 3-8), therefore believers will rise (vv. 20-23), therefore everything done in hope of that rising has coherent meaning.
The common misreading
What the commentators say
Clarke argues that baptism in the early church was received as an emblem of both death and resurrection — going under the water picturing burial, rising out of it picturing new life. Those baptized amid intense persecution were, in effect, dedicating themselves in view of likely martyrdom, joining the company of those who had already died in faith. To be 'baptized for the dead' was therefore to be baptized in solidarity with, and in hope of sharing in, the resurrection of believers who had already died.
JFB notes that Paul uses the practice as an ad hominem argument — the same move Jesus made in Matthew 12:27. Whatever the Corinthians were doing, their own behavior testified to a belief in resurrection. Paul does not endorse or sanction the rite; he simply turns it back on those who denied the resurrection, asking: what exactly do you think you are accomplishing if the dead are not raised? The argument exposes a glaring inconsistency in their position.
Gill reads the verse as part of Paul's larger argument that denying resurrection collapses the entire logic of the Christian life — leading inevitably to the Epicurean conclusion 'let us eat and drink, for tomorrow we die' (v. 32, echoing Isaiah 22:13). Baptism performed in any sense 'for' or 'over' the dead only has coherent meaning if the dead will in fact rise; without resurrection, the practice is empty ritual and Paul's own sufferings are pointless.
The word behind it
'To dip, immerse, baptize.' The word itself carries the image Paul exploits in Romans 6:3-5 — going under the water as burial, coming up as resurrection. That symbolic structure is exactly what makes his argument work: baptism, by its own imagery, assumes a resurrection. A baptism with no resurrection behind it is, on Paul's own theology, a burial with no rising — an incoherent act. The preposition 'for' (hyper) is the crux of interpreters' debates, but Paul's rhetorical point stands regardless of which precise practice is in view.
