Verse explainer
One of the Bible's most debated lines — but the context points to Noah's day, not a post-death second chance.
By which also he went and preached unto the spirits in prison;
BSBin whom He also went and preached to the spirits in prison
The plain meaning
Peter has just said Christ was 'put to death in the flesh but made alive in the Spirit' (v. 18), and it is by that same Spirit he 'went and preached to the spirits in prison.' Verse 20 identifies those spirits immediately: 'who formerly were disobedient, when God's patience waited in the days of Noah.' The most natural reading is that Christ, through the Spirit, preached through Noah to the antediluvian generation during the 120 years of ark-building — that generation is now 'in prison,' held under divine judgment. This reading requires no gap between death and resurrection, no descent into a literal underworld, and fits the surrounding argument: Peter is encouraging believers who suffer for doing right, pointing to Noah as a pattern of faithful witness amid a hostile world. The payoff lands in vv. 20–22: as Noah was saved through water, so believers are now saved through baptism — both upheld by Christ's resurrection and authority over all powers.
The common misreading
What the commentators say
Clarke argues that Christ, through his Spirit, preached by means of Noah to the antediluvians during the 120-year period of the ark's construction. The 'spirits in prison' are those convicted souls held under the arrest of divine justice, awaiting either repentance or the judgment that fell in the flood. He supports this by citing Genesis 6:3 — 'My Spirit shall not always strive with man' — as evidence that the Spirit's activity in that era is exactly what Peter has in mind.
Gill reads the passage in close connection with vv. 20–21, where the ark and baptism are brought together as type and antitype. His concern is less with the 'preaching to spirits' than with what Peter draws from it: Noah and his family passing through water prefigures baptism, which is linked to Christ's resurrection. The surrounding argument is about faithful endurance and the saving work of Christ — the reference to the antediluvians anchors that typology in history.
The word behind it
Dative plural of 'pneuma' — 'spirits.' The word can refer to disembodied souls, angelic beings, or, as Adam Clarke carefully argues, living persons understood as 'spirits' in the same sense as 'the Father of spirits' (Heb. 12:9) and 'the spirits of just men made perfect' (Heb. 12:23), both of which apply the word to persons still in ordinary human existence. The meaning here turns on whether these are spirits now imprisoned (having once been living people) or spirits encountered in some intermediate state — and v. 20's immediate identification of them as Noah's contemporaries strongly favors the former.
