Do you mean these verses:
1Pe 3:18 For Christ also suffered once for sins, the just for the unjust, that He might bring us to God, being put to death in the flesh but made alive by the Spirit,
1Pe 3:19 by whom also He went and preached to the spirits in prison,
1Pe 3:20 who formerly were disobedient, when once the Divine longsuffering waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight souls, were saved through water.
It doesn't say that the spirits were in Hades. It says the spirits were in prison. The Bible says that unsaved sinners are captives (prisoners) of the devil:
2Ti 2:26 and that they may come to their senses and escape the snare of the devil, having been taken captive by him to do his will.
Jesus certainly preached to such captives, and made many of them free.
Notable supporters or strong advocates include
Thomas R. Schreiner,
Peter H. Davids,
J. Ramsey Michaels, and a number of contemporary Petrine scholars; the interpretation also has deep roots in early Christian interpretation because Genesis 6 was widely read as an angelic transgression. Schreiner's current position is particularly clear: the
πνεύματα ἐν φυλακῇ are demonic/fallen angelic spirits associated with the rebellion of Genesis 6:1–4, and Christ's proclamation announces His victory and their defeat—not an offer of salvation.
The Greek is remarkably favorable to the angel interpretation
The crucial expression is:
τοῖς ἐν φυλακῇ πνεύμασιν
tois en phylakē pneumasi
“to the spirits in prison”
The important word is
πνεύμασιν — pneumasi, dative plural of
πνεῦμα, pneuma.
When the New Testament uses
πνεύματα, “spirits,” absolutely—that is, without qualifying them as the spirits of human beings—it very commonly means
supernatural spirit beings: angels or demons. Schreiner specifically notes this. Examples include Matthew 8:16; 12:45; Mark 3:11; Luke 10:20; Acts 8:7; 19:12–13.
That matters because when Scripture wants unmistakably to identify departed human beings as “spirits,” it normally supplies a qualifier. For example:
Hebrews 12:23:
πνεύμασι δικαίων τετελειωμένων
“the
spirits of righteous men made perfect.”
David Gooding makes precisely this observation: Hebrews does not simply call deceased believers
pneumata; it identifies them as the spirits
of righteous people. In 1 Peter 3:19 Peter simply says
the spirits.
So:
πνεύματα alone → naturally supernatural beings
πνεύματα + human qualifier → can clearly denote deceased humans
That by itself doesn't prove the angel interpretation, but it certainly pushes in that direction.
Then comes φυλακή — phylakē
This may be even more significant.
φυλακή means a place of guarding, custody, confinement—hence
prison.
Schreiner points out a striking problem for the human interpretation:
φυλακή is not otherwise used in the NT as the postmortem abode of deceased human souls, whereas the concept of supernatural beings being held in confinement awaiting judgment is explicitly biblical.
Compare:
Jude 6
angels who abandoned their proper domain are kept in eternal bonds under darkness awaiting judgment.
And:
2 Peter 2:4
God did not spare angels when they sinned, but committed them to Tartarus, keeping them for judgment.
Gooding therefore observes that we already know from Jude and 2 Peter that
fallen spirit beings are being held in confinement awaiting judgment, making
pneumata en phylakē an extraordinarily natural description of them.
And Peter himself tells us WHEN they sinned
This is where the argument becomes formidable.
Peter doesn't merely say:
He continues:
1 Peter 3:20
“Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing...”
So Peter gives us:
spirits → disobedience → Noah → Flood.
Now compare Peter's second epistle:
2 Peter 2:4–5
angels sinned → imprisoned → Noah → Flood.
And Jude:
Jude 6
angels → abandoned proper habitation → imprisoned → judgment.
That produces an extraordinary three-text correspondence:
| 1 Peter 3 | 2 Peter 2 | Jude 6 |
|---|
| πνεύματα spirits | ἀγγέλων angels | ἀγγέλους angels |
| disobeyed | sinned | abandoned proper domain |
| imprisoned | Tartarus/confinement | eternal bonds |
| Noah | Noah | boundary violation |
| Flood | Flood | judgment |
This is one of the principal reasons Schreiner accepts the angelic interpretation. He says 1 Peter 3:20 identifies these spirits with the rebellious angels associated with Genesis 6, and notes that
Second Temple Jewish literature, Jude 6, and 2 Peter 2:4 all reflect this reading of Genesis 6.
The word κηρύσσω is important too
Peter says:
ἐκήρυξεν — ekēryxen
from
κηρύσσω — kēryssō
It means
to herald, announce, proclaim.
Peter does
not say:
εὐαγγελίζομαι — euangelizomai
“to evangelize / announce good news.”
That considerably weakens the idea that Jesus went there offering salvation to dead humans.
Schreiner expressly makes this distinction:
kēryssō does not inherently mean evangelistic preaching. Christ may be
announcing His triumph and their judgment.
That interpretation also makes excellent sense of the end of the paragraph.
Peter begins:
3:19 — Christ went/proclaimed to imprisoned spirits.
And ends:
3:22
Christ “is gone into heaven, and is on the right hand of God; angels and authorities and powers being made subject unto him.”
Remarkably, Peter uses the same verb:
πορευθείς — poreutheis, “having gone”
in
3:19 and
3:22.
Schreiner consequently sees the whole thing as a triumphal sequence:
Death → Resurrection → Ascension → proclamation of victory over supernatural powers.
And then Genesis 6 suddenly makes perfect sense
Without the angel interpretation, Peter's sudden reference to Noah is rather peculiar:
Christ → spirits → prison → Noah → ark → baptism → resurrection → angels subjected to Christ.
But under the Genesis 6 interpretation there is a continuous thought:
Genesis 6 angelic rebellion
↓
fallen spirits confined
↓
Noah/Flood judgment
↓
eight humans delivered through water
↓
Christ's resurrection
↓
Christ ascends victoriously
↓
angels, authorities and powers subjected to Him
Schreiner explicitly says the Genesis 6 interpretation explains
why Peter suddenly introduces Noah at all.
And there is another important background piece:
1 Enoch. Peter's Jewish audience would have known a widespread interpretation in which the “sons of God” of Genesis 6 were rebellious heavenly beings who violated their assigned order and were subsequently
bound/imprisoned awaiting judgment. Jarvis Williams notes that this same interpretive tradition appears in 1 Enoch, Jubilees, Jude and 2 Peter.
So I would rank the linguistic evidence roughly this way:
πνεύματα — favors supernatural spirits.
ἐν φυλακῇ — strongly fits supernatural beings confined for judgment.
ἀπειθήσασίν ποτε — they committed a particular former rebellion.
ἐν ἡμέραις Νῶε — explicitly locates it in Noah's era.
ἐκήρυξεν — proclamation, not necessarily evangelization.
πορευθείς in vv.19 and 22 — links the proclamation with Christ's victorious ascension.
ἀγγέλων...ἐξουσιῶν...δυνάμεων in v.22 — concludes the passage with Christ's supremacy over precisely the sort of supernatural beings introduced in v.19.
Put
1 Peter 3:19–22 + 2 Peter 2:4–5 + Jude 6 + Genesis 6:1–4 beside one another, and the fallen-angel interpretation becomes, in my assessment,
exegetically very strong. It also arguably gives
pneumata en phylakē its most straightforward meaning:
supernatural spirits held in confinement because of their antediluvian rebellion.
One correction to my previous answer is warranted:
Schreiner definitely supports this view; the current Logos discussion with him states it explicitly.
