If you grew up in a conservative Protestant church, there is a decent chance you heard a fairly simple explanation of Genesis 6. The “sons of God” were the godly descendants of Seth, the “daughters of men” were the sinful descendants of Cain, and the problem was that the righteous line compromised itself through intermarriage. It was a tidy interpretation, it kept angels from having sex with humans, and for a long time it was treated in many churches as though Christians had basically always read the passage that way.

They did not. In fact, if you walked into a Christian community in the second century and announced that the “sons of God” could not possibly be heavenly beings, you would be arguing against some of the most important Christian writers of the age. Justin Martyr, Athenagoras, Irenaeus, Clement of Alexandria, and Tertullian all knew versions of the tradition in which heavenly beings transgressed their appointed order, desired human women, descended, and became connected with the corruption of the pre-Flood world.

That does not automatically make the angelic interpretation correct. The church fathers are not inspired, early Christian popularity is not the same thing as apostolic authority, and the elaborate Watcher mythology of 1 Enoch should not simply be poured back into the four terse verses of Genesis 6 as though every later detail appeared there. But the history matters, because the interpretation popularized in modern evangelical circles by Michael Heiser is not a modern invention. The surprising question is not, “When did Christians invent the idea that the sons of God were angels?” The better historical question is, when did many Christians stop reading them that way?

The short answer: there was no single moment

There was no council where bishops voted the Watchers out of Genesis 6. There was no pope who decreed that the “sons of God” were now Sethites, and Augustine did not simply invent the human interpretation out of thin air. The evidence instead shows a gradual shift beginning by the early third century, becoming much more aggressive in the late fourth century, and becoming dominant across major Greek and Latin theological traditions during the fifth century.

Jaap Doedens, whose major study The Sons of God in Genesis 6:1–4 traces the history of interpretation in detail, identifies Julius Africanus as an important early witness to the Sethite reading. Doedens also notes that from roughly the fifth through the twelfth century the Sethite interpretation was applied with remarkable dominance. That does not mean every Christian abandoned the angelic reading in AD 400, but it does mean something substantial had changed.

Even around AD 400, the change was not complete. Sulpicius Severus could still narrate the pre-Flood story straightforwardly as a story about angels marrying women and producing giants. At approximately the same time, John Chrysostom was preaching that people who interpreted the passage in precisely that way were turning Scripture into mythology. The disagreement is almost too perfect: two Christians separated by geography and theological culture, living at roughly the same moment, preserve opposite sides of a transition already underway.

Before the church fathers, there was the Book of the Watchers

Genesis 6:1–4 is frustratingly brief. Human beings multiply, the “sons of God” see that the daughters of humanity are beautiful, they take wives, the Nephilim appear in the story, and the narrative moves rapidly toward the violence and wickedness preceding the flood. Genesis never calls these beings “Watchers,” never names Semjaza or Azazel, and never says that two hundred angels descended on Mount Hermon.

Those details come from the ancient Jewish work we call 1 Enoch, particularly the Book of the Watchers in 1 Enoch 1–36. George Nickelsburg’s major Hermeneia commentary treats this section as a substantial Jewish interpretation of Genesis 6 in which the brief biblical story is expanded into a cosmic account of transgression, forbidden revelation, giant violence, and judgment. Nickelsburg observes that the Watcher narrative deliberately intensifies the sin implied in Genesis and connects the violence before the flood to both unlawful unions and the disclosure of forbidden knowledge.

The Book of the Watchers was not a medieval fantasy written a thousand years after Christianity began. It belongs to Second Temple Judaism, and the Enochic fallen-angel tradition was already circulating centuries before many of the fathers discussed Genesis 6. Loren Stuckenbruck has documented how widely the rebellious-angel myth was received and adapted across Second Temple Jewish literature, while Archie Wright has traced the relationship between Genesis 6, the Watcher tradition, and developing Jewish explanations for the origin of evil spirits.

That is important because the early Christians who read Genesis 6 supernaturally were not pulling an exotic interpretation out of nowhere. They inherited a Jewish interpretive world in which the phrase “sons of God” could naturally denote heavenly beings and in which Genesis 6 had already generated an enormous tradition about rebellious angels. The Hebrew Bible itself uses “sons of God” language for heavenly beings elsewhere, especially in Job, which is one reason many modern scholars also regard a supernatural reading of Genesis 6 as philologically serious.

For a fuller treatment of the biblical and Second Temple material, see Fresh Ground Theology’s earlier discussions, Who Were the Watchers in Genesis 6? and Who Were the Nephilim, and What Did Genesis Say?. The question here is narrower. What happened once Christians inherited this interpretation?

Justin Martyr treats the angelic fall as Christian history

One of the earliest clear Christian examples comes from Justin Martyr in the middle of the second century. Justin does not present the story as a weird possibility he heard from fringe Christians. He uses the fallen angels as part of his explanation for the origin of demonic religion and the corruption of humanity.

“When God had made the whole world, subjected earthly things to humanity, arranged the heavenly elements for the increase of fruits and the change of seasons, and appointed this divine law, he committed the care of humanity and of everything under heaven to angels whom he placed over them. But the angels transgressed this appointment, were captivated by love of women, and begot children who are those called demons. Afterwards they subdued the human race to themselves, partly by magical writings, partly by the fears and punishments they occasioned, and partly by teaching sacrifices, incense, and libations, which they needed after being enslaved by lustful passions. Among human beings they sowed murders, wars, adulteries, intemperate deeds, and every wickedness.”

Justin Martyr, Second Apology 5

Justin’s version is not identical to every strand of 1 Enoch, and that distinction matters. Yet Annette Yoshiko Reed argues that Justin’s treatment follows the Book of the Watchers particularly closely because he combines the sexual transgression of the angels with their corrupting influence upon human culture. Justin effectively Christianizes the Watcher tradition by using it to explain pagan worship, demons, and the spiritual corruption of the Greco-Roman world.

This is already more than an interpretation of one difficult Hebrew phrase. Genesis 6 has become part of Christian demonology, apologetics, and the theology of pagan religion. The Watcher tradition gives Justin a way to explain why spiritual powers stand behind idolatrous culture without conceding that the gods worshiped by pagans are legitimate rivals to the Creator.

Athenagoras makes the connection even more explicit

A generation later, Athenagoras describes angelic rebellion in language that would sound completely at home in a modern discussion of the Watchers. He argues that angels possess moral freedom, that some remained faithful to their appointed government, and that others violated it through lust. Their offspring become connected with the giants, while the spirits associated with those giants become demons.

“Just as human beings have freedom of choice between virtue and vice, so it is among the angels. Some were created free by God and remained in the things for which God made and appointed them; others outraged both the constitution of their nature and the government entrusted to them. The ruler of matter and its forms, and others placed over this first firmament, fell into impure love of virgins and were overcome by the flesh. Of these lovers of virgins, therefore, were begotten those who are called giants.”

Athenagoras, Plea for the Christians 24

He continues the argument in the following chapter by identifying the souls of the giants with wandering demons. That specific connection closely resembles the demonology of 1 Enoch 15–16, where the dead giant offspring of the Watchers become evil spirits operating upon the earth. This was not merely “angels fell sometime in the remote past.” It was an integrated explanation of where some demonic powers came from and why they remained active in the human world.

That wider demonological framework is one reason Stuckenbruck and Wright matter for this discussion. The significance of the Watcher myth extends beyond the identification of the “sons of God,” because it became one ancient way of explaining why the biblical world could speak so naturally about hostile spiritual beings. Modern readers often encounter demons suddenly in the Gospels and assume that an entire demonology appeared between Malachi and Matthew; Second Temple texts show that Jewish thinkers had been developing these questions for centuries.

Irenaeus and Tertullian are not embarrassed by the Watchers

Irenaeus of Lyons, writing around AD 180, also assumes angelic transgression in the pre-Flood world. In Against Heresies 4.16.2, Enoch becomes God’s envoy to the sinful angels, a detail that goes well beyond the bare narrative in Genesis and fits the Enochic story in which the Watchers ask Enoch to intercede for them. Elsewhere Irenaeus says that the flood came upon a world corrupted after sinful angels had “commingled” with humanity.

Tertullian takes the tradition even further. He does not merely believe angels sinned with women; he deploys Enochic material repeatedly to explain magic, astrology, metallurgy, cosmetics, idolatry, demonology, and even Paul’s difficult phrase “because of the angels” in 1 Corinthians 11:10. Whatever we think of those applications, they show that the supernatural reading was deeply embedded in his theological imagination.

“The angels, deserters from God, were inflamed with desire for women. They revealed the operations of metallurgy, disclosed the natural properties of herbs, divulged the powers of enchantments, and made known every curious art, even the interpretation of the stars. They especially bestowed upon women the means of feminine display: necklaces, armlets, dyes for wool, the dark powder for the eyes, and the arts of ornamenting and painting the face.”

Tertullian, On the Apparel of Women 1.2

Tertullian even recognizes that the authority of Enoch is disputed and mounts an explicit defense of the book. That fact is important because it shows both sides of the developing problem at once: the Watcher tradition remained influential, but Christians were already debating the status of the literature that preserved its fullest form. The eventual decline of the angelic reading therefore cannot be separated completely from the declining authority of Enochic books.

Julius Africanus gives us the first major turn

The earliest Christian evidence for the Sethite interpretation is often associated with Julius Africanus in the early third century. His surviving discussion is especially valuable because he knows both interpretations. He does not write as though nobody had ever heard the angelic reading; he presents it and then states that he prefers to identify the sons of God with the descendants of Seth.

“When men had multiplied on the earth, angels of heaven came together with the daughters of men. In some copies I found ‘sons of God.’ In my judgment, however, it is related of the descendants of Seth that they were called sons of God because of the righteous men and patriarchs descended from him, down to the Savior himself; but the descendants of Cain were called the seed of men because they had nothing divine in them. Yet if we understand the passage to refer to angels, we must take them to be those who dealt with magic and juggling, who taught women the motions of the stars and the knowledge of heavenly things, and through whose power the women conceived the giants.”

Julius Africanus, Chronography, fragment 2

Africanus matters precisely because he stands near the hinge of the history. He knows the older supernatural explanation, he knows the traditions about forbidden heavenly knowledge, yet he judges the Sethite explanation preferable. Doedens treats Africanus as an important point in the emergence of the explicitly Christian Sethite trajectory that would later become overwhelmingly influential.

We should not turn Africanus into the man who single-handedly changed Christian interpretation. He did not. But by the early third century, a Christian intellectual could look at a tradition embraced by Justin, Athenagoras, Irenaeus, and Tertullian and say, in effect, “I know that reading, but I do not think it is the best interpretation of Genesis.”

Origen shows another part of the transition

Origen is even more interesting because he does not simply reject Enoch. He cites the Book of Enoch, knows traditions about the descent of the sons of God, and is capable of treating Enochic material as exegetically useful. At the same time, he repeatedly signals that its authority is uncertain.

In his Commentary on John, Origen refers to the descent of the sons of God to the daughters of men “as it is written in the Book of Enoch,” but adds a revealing qualification: this works “if anyone cares to accept that book as sacred.” In his Homilies on Numbers, he declines to build an argument upon material in Enoch because those books do not appear to be accepted as authoritative among the Hebrews. By the time he answers Celsus, Origen explicitly insists that the books circulated under Enoch’s name are not generally regarded as divine in the churches.

That is not yet the full Sethite rejection we encounter later in Chrysostom and Augustine. It is nevertheless significant because one of the foundations under the older interpretation is becoming unstable. If Christians increasingly distinguish canonical Genesis from a disputed Enochic expansion of Genesis, then the detailed Watcher story can no longer function as unquestioned interpretive background.

Reed’s reception history is especially helpful here because she warns against imagining a simple straight line from Second Temple Enoch to medieval Christianity. Enochic traditions could survive even where Enochic books lost authority, and individual motifs could be preserved, adapted, allegorized, or rejected independently of one another. The history is therefore not “Christians believed Enoch, then they stopped.” It is a gradual disentangling of Genesis, demonology, angelology, and Enochic literature.

But the angelic interpretation did not disappear in the third century

Any clean timeline falls apart when we reach Lactantius. Writing in the early fourth century, Lactantius still presents the angelic interpretation with extraordinary confidence. Angels are sent for humanity’s benefit, the devil tempts them through women, mixed offspring result, and the spirits associated with those offspring become the demons haunting the earth.

“God sent angels for the protection and improvement of the human race, but he forbade them to be polluted by earthly contagion. The devil enticed them to pleasures, defiled them through intercourse with women, and made them unable to return to heaven. Thus they fell to earth. From them and the women were born offspring neither angels nor human beings, but a mixed kind. These became the first earthly race of demons, unclean spirits and authors of the evils later practiced among humankind.”

Lactantius, Divine Institutes 2.15

Even more striking is Sulpicius Severus around AD 403. By this point Chrysostom had already condemned the angelic interpretation in the Greek East, yet Sulpicius could still write sacred history in which heavenly angels marry women and produce giants. His account shows why we should speak of a changing Christian consensus rather than a universal doctrinal reversal.

“At this time, when the human race had multiplied, certain angels whose dwelling was in heaven were captivated by the beauty of virgins. Leaving the higher region of which they were inhabitants, they joined themselves in earthly marriages. These angels gradually spread wicked habits, corrupted the human family, and from their unlawful unions giants sprang forth, beings of enormous bodies and savage character. In this way the whole earth was filled with monsters and violence until God resolved to destroy the corrupted race by the flood.”

Sulpicius Severus, Sacred History 1.2

That passage was written at almost exactly the historical moment when the competing interpretation was becoming dominant. It is an excellent reminder that “the early church believed” is almost always a dangerous sentence unless we specify which Christians, where, and when. Christian interpretation did not change everywhere at the same speed.

John Chrysostom calls the angelic reading mythology

The tone changes dramatically with John Chrysostom in the late fourth century. Chrysostom does not approach the supernatural reading as an honorable alternative. He treats it as an irresponsible interpretation that needs to be refuted.

“Some speak carelessly and turn the passage into a myth, claiming that it refers not to men but to angels, whom Scripture supposedly calls sons of God. First let them show where angels are called sons of God. They cannot. Scripture calls them angels, archangels, cherubim, and seraphim, but never sons of God. The descendants of Seth were called sons of God because of their virtue, while the daughters of men were the descendants of Cain.”

John Chrysostom, Homilies on Genesis 22

Modern readers familiar with Job 1:6, 2:1, and 38:7 will immediately see the difficulty in Chrysostom’s categorical claim that Scripture never calls heavenly beings “sons of God.” That does not mean his entire argument can be dismissed. It does mean that the argument arises within a different exegetical framework than the one used by many contemporary Hebrew Bible scholars.

Doedens’ historical survey captures the significance of this stage. The angelic, ruler, and Sethite interpretations competed for centuries, but the Sethite reading rose dramatically in late patristic Christianity and became nearly exclusive for much of the medieval period. Chrysostom is therefore not an isolated eccentric; he represents a theological and hermeneutical current that was rapidly becoming stronger.

Augustine helps make the new reading dominant in the West

Augustine is often blamed for “inventing” the Sethite interpretation, which is historically inaccurate. Julius Africanus had proposed it almost two centuries earlier, and Chrysostom was already defending it vigorously in the Greek-speaking church. Augustine’s importance lies elsewhere: his enormous influence helped make the interpretation normative in the Latin West.

In City of God 15.22, Augustine connects Genesis 6 to the two cities that structure his reading of human history. The sons of God belong to the godly line descended from Seth, while the daughters of men belong to Cain’s earthly line. The sin is therefore not angel-human reproduction but the collapse of separation between two human communities ordered toward different loves.

“The sons of God who took wives from the daughters of men were the sons of Seth according to the flesh, belonging to the city of God, while the daughters of men were descended from Cain and belonged to the earthly city. Scripture calls these men angels because they were messengers and because of the holiness by which they adhered to God. It is therefore unnecessary to suppose that spiritual angels entered bodily unions with women.”

Augustine, City of God 15.22

Augustine’s treatment becomes even more interesting in the next chapter because he does not simply declare all stories about sexual spirits impossible. He is willing to acknowledge reports about spirits behaving sexually and is more cautious than people sometimes remember. What he rejects is the idea that the holy angels called “sons of God” in Genesis should be identified with such beings and the idea that the Enochic books circulating in his day possess sufficient canonical authority to settle the question.

Augustine also connects the Genesis 6 debate with the problem of Enoch’s textual authority. He accepts Jude’s statement that Enoch prophesied, yet he argues that the writings attributed to Enoch cannot be reliably authenticated simply because they bear the patriarch’s name. Here canon, textual transmission, and exegesis begin reinforcing one another: a disputed Enochic book should not control the interpretation of canonical Genesis.

That development fits the larger history charted by Reed. The Book of the Watchers had once powerfully shaped Jewish and Christian readings of primeval history, but Enochic literature became increasingly marginal within the dominant Greek and Latin churches. As that happened, Genesis 6 was increasingly interpreted without the narrative world that had once surrounded it.

By the fifth century, the rejection becomes much broader

Augustine was not alone. John Cassian rejects the angelic interpretation because, in his view, spiritual beings cannot generate bodily offspring and because the flood narrative emphasizes human guilt. His alternative is explicitly Sethite: the sons of God are Seth’s descendants, the daughters of men are Cain’s descendants, and the giants remain fully human.

Cyril of Alexandria makes a similar move from the Greek East. He regards the fallen-angel interpretation as both exegetically unwarranted and theologically incoherent, arguing that Scripture’s “sons of God” are the righteous descendants of Seth and Enosh. Theodoret of Cyrus later adds a moral argument: if angels caused the catastrophe through sexual sin, why does the flood fall upon humanity?

These are not identical objections. One concerns angelic embodiment, another concerns the wording of Scripture, another concerns human responsibility, and another concerns the justice of divine judgment. Their convergence is what matters historically.

By the middle of the fifth century, substantial representatives of both Greek and Latin Christianity are no longer merely cautious about Enoch. They are actively reconstructing Genesis 6 around a human interpretation, and the older angelic reading increasingly appears to them not as inherited Christian common sense but as an exegetical problem requiring correction.

Why did the interpretation change?

No single explanation accounts for the shift. The first major factor was almost certainly the changing status of Enochic literature itself. The early Christians who inherited the Watcher reading possessed a living interpretive tradition in which Enoch provided names, motives, punishments, demonology, and narrative connections that Genesis leaves unstated; once Enoch became increasingly disputed or marginalized, those connections became much easier to question.

Reed’s work is crucial here because she treats the history of Enoch as a history of reception, adaptation, and community boundaries rather than simply a question of “canonical versus noncanonical.” Proto-orthodox Christians initially appropriated Enochic traditions enthusiastically, sometimes using the fallen angels to explain pagan religion and forbidden knowledge. Later Christian interpretation could preserve portions of that supernatural worldview while becoming increasingly suspicious of the textual traditions that had carried it.

A second factor was the developing Christian understanding of angelic nature. If angels are incorporeal spiritual beings, what exactly would it mean for them to produce biological children with women? Cassian and Theodoret press that objection hard, and once the metaphysical problem becomes central, the Sethite reading offers an elegant escape from it.

A third factor was the theological location of human guilt. Genesis moves from the strange sons-of-God episode directly toward the declaration that human wickedness had become great upon the earth. Later interpreters worried that the Watcher interpretation seemed to shift the responsibility for the flood away from humanity and toward invading spiritual beings; Cassian and Theodoret explicitly make versions of that argument.

A fourth factor was hermeneutical restraint. The Book of the Watchers answers questions Genesis itself does not answer, but that strength can also become a weakness once an interpreter begins asking whether an apocryphal expansion has been allowed to control the canonical narrative. The same concern is still legitimate today, even for those of us who think the supernatural interpretation of Genesis 6 is probably correct.

Does modern scholarship simply prove the early fathers were right?

Not quite. Modern scholarship has certainly made it much harder to dismiss the supernatural interpretation as primitive mythology. The Hebrew expression bene ha’elohim has close parallels elsewhere in the Hebrew Bible where heavenly beings are clearly in view, and the supernatural reading makes good sense within the wider ancient Near Eastern and Second Temple context.

At the same time, we should distinguish Genesis 6 from the entire Enochic narrative built around it. Nickelsburg’s analysis shows that the Book of the Watchers is itself interpreting and expanding Genesis, not simply preserving four missing verses accidentally left out of our Bibles. Its stories about angelic instruction, giant spirits, named Watchers, and cosmic secrets represent developed traditions with their own compositional histories.

Amar Annus pushes the comparative question still further by arguing that parts of the Watcher tradition interact polemically with Mesopotamian traditions about antediluvian sages, the apkallu. On his reading, the Jewish Watchers tradition turns revered culture-bearing figures into dangerous or rebellious transmitters of forbidden knowledge. Whether every part of that reconstruction convinces us or not, the comparison reminds us that 1 Enoch is doing sophisticated ancient theology, not merely giving us a stenographic report of events omitted from Genesis.

That distinction matters for a Fresh Ground Theology approach. We can say that Genesis 6 most naturally refers to heavenly beings without insisting that every detail of 1 Enoch must therefore be historical. We can also acknowledge that 1 Enoch preserves enormously important evidence for how ancient Jews interpreted Genesis without quietly granting it the authority of Genesis itself.

Jude and 2 Peter make the Sethite solution harder

There is also a New Testament problem for the idea that the supernatural interpretation can simply be dismissed as pagan mythology. Jude describes angels who did not keep their proper domain but abandoned their dwelling, places their judgment near language about sexual transgression, and then explicitly quotes a prophecy attributed to Enoch. Second Peter likewise speaks of angels who sinned, their confinement for judgment, and the flood of Noah in the same sequence.

That does not prove that Jude canonizes the entire Book of Enoch. It does mean that the New Testament writers operate within a conceptual world in which rebellious angels associated with the primeval age are readily intelligible. Fresh Ground Theology has discussed that evidence in more detail in Who Were the Nephilim, and What Did Genesis Say?.

This is where the Sethite interpretation is weakest for me. It may solve the metaphysical problem of angel-human reproduction, and it keeps the flood focused squarely on human wickedness, but it does not explain the Second Temple and New Testament evidence nearly as naturally as the heavenly-being interpretation. Jude and 2 Peter do not read like writers trying to rescue Genesis 6 from an embarrassing angelic misunderstanding.

Michael Heiser did not resurrect a fringe interpretation

One of Michael Heiser’s most important contributions to popular evangelical theology was not inventing the supernatural reading but reminding modern readers that the biblical world contains a populated supernatural realm. The “sons of God” language in Job, the divine council material, Second Temple traditions, Jude, 2 Peter, and the history of early Christian interpretation all make considerably more sense once readers stop assuming that every spiritual being in Scripture must fit into the single modern category “angel.” Fresh Ground Theology’s broader discussion of that framework can be found in Who Are the “Gods” of the Old Testament?.

But Heiser’s recovery of the ancient context should not become permission to erase the distinction between Scripture and Second Temple interpretation. Saying “the Watcher tradition helps explain Jude” is different from saying “everything in 1 Enoch is therefore what really happened.” The fathers themselves eventually demonstrate why the distinction is necessary, even if some of them reacted too far in the opposite direction.

There is a useful methodological lesson here. Read Genesis as Genesis, read 1 Enoch as an ancient interpretation of Genesis, read Jude and 2 Peter as inspired New Testament texts that clearly know the wider tradition, and then ask carefully where the lines of dependence and affirmation actually run. That method is slower than simply declaring either “Enoch explains everything” or “Enoch is apocrypha, so ignore it,” but it is historically and exegetically much stronger.

So when did Christians stop believing the sons of God were fallen angels?

If we need a date, we should resist the temptation. The second century gives us Justin, Athenagoras, Irenaeus, and Tertullian using versions of the angelic interpretation with remarkable confidence. The early third century gives us Julius Africanus preferring the Sethite interpretation and Origen revealing increasing uncertainty about the authority of Enochic literature.

The fourth century remains mixed. Lactantius still embraces an elaborate supernatural account, while Chrysostom attacks the angelic interpretation as mythology. Around AD 403, Sulpicius Severus proves that Christians could still narrate angel-human unions straightforwardly even after leading theologians had begun rejecting them.

The decisive consolidation comes during the late fourth and fifth centuries. Chrysostom, Augustine, Cassian, Cyril of Alexandria, and Theodoret represent a powerful Greek-and-Latin movement toward the Sethite reading, and the medieval dominance of that interpretation follows. Doedens’ history of exegesis confirms just how dramatically the balance shifted: from the fifth century onward, the Sethite reading became overwhelmingly influential for many centuries.

So the best answer is not, “Christians stopped believing the sons of God were angels when Augustine told them to.” The better answer is that the ancient angelic interpretation began losing ground during the third century and ceased to be the dominant interpretation in major Greek and Latin Christianity during the fourth and fifth centuries. Augustine helped cement the transition in the West, but he inherited an argument already well underway.

Why this history matters

The history should make both sides of the modern debate a little less comfortable. Christians who dismiss the heavenly-being interpretation as a bizarre modern novelty have to reckon with the fact that major second-century theologians accepted versions of it with little embarrassment. Christians who treat 1 Enoch as though recovering the Watchers automatically settles every question have to reckon with the fact that serious early Christian interpreters eventually distinguished the biblical text from its Enochic expansion and raised questions that still deserve answers.

For my part, I think the older supernatural reading fits the language of Genesis 6, the wider biblical use of “sons of God,” and the New Testament evidence better than the Sethite interpretation. I also think parts of the Watcher tradition preserve ancient interpretive insights that modern Christians lost when Enoch disappeared from most Christian reading. Neither conclusion requires us to pretend that 1 Enoch is canonical or that every detail in its composite tradition is historically reliable.

The most interesting result is therefore not that Michael Heiser proved Augustine wrong or that Augustine rescued Christianity from Jewish mythology. It is that Genesis 6 sits at the intersection of Scripture, Second Temple Judaism, demonology, canon formation, and the history of Christian interpretation. When we recover that history, the passage becomes stranger than many of us were taught, but it also becomes considerably more intelligible.

And perhaps that is the best reason to revisit the argument. The church’s interpretation of Genesis 6 changed because Christians were wrestling with real questions about Scripture, tradition, angels, human guilt, and the boundaries of authoritative revelation. We should be willing to wrestle with those same questions without flattening either the biblical supernatural worldview or the complexity of Christian history.
