The Fate of the Nephilim and the Origin of Demons

Question: What happened to the spirits of those born of the sons of God and the daughters of men who died in the flood? Could their spirits be what the King James Version calls "devils" (demons), rather than demons being fallen angels?

This answer argues from the text, not from tradition. If the passage will not carry a doctrine, the doctrine is set aside.

Originally published in Vol. 1, Number 1, Ask The Theologian Journal.

The question challenges a common assumption: that demons are simply fallen angels. It proposes an alternative: that demons might be the disembodied spirits of the Nephilim---the offspring of the "sons of God" and the "daughters of men" in Genesis 6---who perished in the flood. This is a thoughtful inquiry that deserves careful consideration.

subsection*1. The Standard View: Demons as Fallen Angels

The widespread traditional view is:

  • "Sons of God" in Genesis 6 are understood as angels who took human women and produced offspring.
  • Some angels fell with Satan and became what we now call demons.
  • Demons are thus fallen angels, of the same basic nature as other angels but morally corrupt and opposed to God.

This view has strengths: - It fits the broad biblical picture that associates evil spirits with Satan's angelic hosts. - It allows for a unified category of heavenly beings, some loyal and some fallen.

However, Scripture does not plainly state, "Demons are fallen angels." That connection is inferred. This leaves conceptual space for exploring whether something more complex is going on.

subsection*2. The Alternative Hypothesis: Demons as Nephilim Spirits

The alternative proposal is as follows:

  1. The "sons of God" (Genesis 6) are angelic beings.
  2. Their unions with human women produced hybrid offspring, often called the Nephilim.
  3. These hybrid beings were destroyed in the flood. Their bodies perished.
  4. Their spirits---neither fully angelic nor fully human---were left in an anomalous state.
  5. The suggestion is that these spirits, now disembodied, are what Scripture calls demons or "devils" in the King James Version.

This view attempts to explain: - Why demons might seem to be "homeless" spirits seeking embodiment. - Why they are consistently evil and associated with rebellion. - Why their activity appears principally after the flood in the narrative.

subsection*3. The "Spirits in Prison" and Their Possible Relation

There is a passage---likely the one you have in mind---in 1 Peter (or 2 Peter) that refers to "spirits in prison." It connects these imprisoned spirits with the days of Noah.

Without reproducing the full passage word-for-word, the relevant points are:

  • There are spirits that are "kept" or "in prison."
  • They are associated in some way with the time of Noah and the events around the flood.
  • Later prophetic passages indicate a future release of imprisoned beings for a brief period of intense activity.

How might this fit with the Nephilim hypothesis?

One way to synthesize the data is:

  • The Nephilim died in the flood; their bodies disintegrated over time.
  • Their spirits were placed under restraint---"in prison," "in the abyss," or some similar state of confinement.
  • Revelation speaks of imprisoned entities that will be released for a limited time of tormenting activity.
  • It is at least conceivable that some of the demonic manifestations in the Gospels could have been a foretaste or limited release of that same class of spirits.

Under this view, demons would not be fallen angels per se, but the disembodied spirits of hybrid beings judged in the flood.

subsection*4. Evaluating the Two Views Side by Side

To handle this responsibly, it is helpful to set the two models side by side and ask which one fits the whole of Scripture more plausibly.

subsubsectionA. Demons as Fallen Angels

  • Pros: beginitemize
  • Keeps all supernatural spiritual beings in two main categories: God's angels and Satan's fallen angels.
  • Aligns with texts that speak of Satan's "angels" and evil spiritual powers under his authority.
  • Explains demonic intelligence and power as angelic in nature.

item Challenges:

  • Does not, by itself, explain the peculiar "homeless" language of demons seeking rest and hosts.
  • Requires some explanation for why fallen angels would not simply behave like other angels, other than moral corruption.

subsubsectionB. Demons as Nephilim Spirits

  • Pros: beginitemize
  • Explains why demons seem to be disembodied and eager to inhabit bodies.
  • Connects the timing of demonic activity with the aftermath of Genesis 6.
  • Uses the category of "spirits in prison" as a possible textual foothold.

item Challenges:

  • Needs a clear biblical statement that these specific spirits are what we later call demons, which Scripture never explicitly provides.
  • Still must explain where Satan's angelic host fits, if demons are now something distinct from fallen angels.
  • Could risk multiplying categories of hostile spiritual beings beyond what Scripture clearly delineates.

subsection*5. Could Both Elements Be Present?

It is conceptually possible that: - There are fallen angels (Satan's angels), and - There are other evil spirits related to the Nephilim episode.

In that case, some of what we call "demons" might be fallen angels, and some might be Nephilim spirits. But this quickly becomes speculative. Scripture rarely draws fine-grained distinctions among varieties of evil spirits. It tends to speak more generally of "unclean spirits," "demons," or Satan's "angels."

subsection*6. A Cautious Assessment

You asked whether the spirits of those Nephilim who died in the flood could be what the King James Version calls "devils." The answer is: they could be, in the sense that nothing in Scripture definitively forbids that line of thought. The idea has some internal coherence and interacts seriously with the biblical storyline.

However, a few cautions are appropriate:

  • Scripture never directly says that "demons" are the spirits of the Nephilim. The connection must be built by inference and synthesis.
  • Scripture frequently associates Satan with "his angels," and the New Testament uses "demons" for hostile spirits active in the Gospels and Acts. The most straightforward reading is that these belong to the fallen angelic host.
  • The "spirits in prison" language gives us a category, but we must not too quickly equate it with all demons without a clear textual bridge.

Given this, a responsible position might be:

  1. The primary, simplest identity for demons is that they are fallen angels, members of Satan's hostile spiritual host.
  2. The Nephilim episode and the "spirits in prison" may indicate a special subset of evil spirits under particular judgment, possibly distinct in some ways from the broader demonic host.
  3. The proposal that demons are exclusively or primarily Nephilim spirits is an interesting conjecture that invites study, but it cannot be asserted with the same confidence as doctrines directly and repeatedly taught in Scripture.

subsection*7. How to Proceed Theologically

Your question does exactly what good theological reflection should do: it questions assumptions and checks whether those assumptions are textually grounded or merely traditional. To develop this line of inquiry further, one would:

  1. Carefully catalog every biblical reference to: beginitemize
  2. Demons/unclean spirits.
  3. The Nephilim and Genesis 6.
  4. "Spirits in prison" or spirits associated with the days of Noah.
  5. Imprisoned fallen angels and later releases of evil beings.

item For each reference, ask:

  • What is explicitly stated?
  • What is implied but not directly stated?
  • What must be imported from other texts, and is that import justified?

item Then build parallel arguments:

  • One argument for demons as fallen angels.
  • One argument for demons as Nephilim spirits.
  • Possibly a combined model if the evidence appears mixed.

endenumerate

Only after such work could one responsibly prefer one model over another.

subsection*8. A Balanced Conclusion

  • The standard view that demons are fallen angels is coherent and grounded in the broader biblical association of evil spirits with Satan's angelic host.
  • The proposal that demons might be the disembodied spirits of the Nephilim is not without merit and can be developed in engagement with texts about the days of Noah and "spirits in prison."
  • At present, Scripture does not explicitly equate Nephilim spirits with demons, so any such equation remains a theological hypothesis rather than a clear, defined doctrine.

Therefore, your suggestion is a legitimate and interesting way to "question the assumptions," and worth exploring further. However, it should be held with appropriate tentativeness alongside the more widely supported identification of demons as fallen angels.
