When reading the New Testament, modern audiences generally assume that the early Christians strictly read and referenced the exact same collection of Old Testament books that sit bound on our shelves today. However, historical-critical scholarship reveals a much more complex literary reality. The Epistle of Jude contains one of the most fascinating literary anomalies in the entire biblical canon: a direct, explicit quotation from the non-canonical Book of Enoch.
This brief reference shatters the misconception of a closed ancient library. It provides a vivid, undeniable glimpse into the theological world of first-century Judaism and demonstrates that early Christians drew inspiration from a vast and fluid collection of sacred texts.

The Direct Quotation in Jude

In the brief Epistle of Jude, the author writes to fiercely warn his community about corrupt teachers who have infiltrated their ranks. To prove that these intruders are destined for divine judgment, Jude quotes an ancient prophecy to back up his theological argument.
Jude 1:14–15 declares: “Enoch, the seventh from Adam, prophesied about them: ‘See, the Lord is coming with thousands upon thousands of his holy ones to judge everyone, and to convict all of them of all the ungodly acts they have committed in their ungodliness, and of all the defiant words ungodly sinners have spoken against him.'”
This is not a vague allusion or a passing cultural reference. Jude is quoting almost verbatim from the opening chapter of the ancient text known as 1 Enoch (specifically, 1 Enoch 1:9). More importantly, the author of the epistle treats the text not merely as good literature, but as authoritative, inspired prophecy, explicitly attributing the words to the historical, ancient figure of Enoch.

The Fluidity of the Ancient Canon

Finding a quotation from 1 Enoch in the New Testament is a goldmine for biblical scholars because it illustrates how the early Christians viewed scripture. In the first century CE, the “Bible” as a closed, definitive list of books simply did not exist. Second Temple Judaism possessed a vast, dynamic library of sacred texts.
The Book of Enoch was incredibly popular and highly revered by many Jewish communities during this era. The Essenes, the ascetic Jewish sect living at Qumran, preserved multiple copies of it in the Dead Sea Scrolls alongside texts like Isaiah and the Psalms. The author of Jude clearly belonged to a theological stream that considered 1 Enoch to be a vital, authoritative part of their religious library.

Pseudepigrapha and the Apocalyptic Worldview

Modern historians recognize that the historical Enoch—the legendary man from Genesis who lived before the Flood—did not actually write the Book of Enoch. The text was composed and expanded in stages between the third century BCE and the first century CE. It belongs to a well-known ancient literary genre called pseudepigrapha, which refers to writings falsely attributed to an ancient, revered figure in order to give the text immediate authority. Because the Book of Genesis states that Enoch “walked with God and was no more,” implying he was taken into the heavenly realm without experiencing death, he was the perfect literary vehicle for later scribes to use as a mouthpiece for heavenly visions.
1 Enoch is a masterpiece of ancient Jewish apocalyptic literature. It features fallen angels known as the Watchers, terrifying cosmic judgments, and vivid descriptions of the end of the world. The early Christian movement was deeply apocalyptic, intensely anticipating the imminent return of Jesus to judge the earth. Jude quotes Enoch precisely because 1 Enoch’s dramatic vision of God arriving with “thousands of his holy ones” perfectly fit the early Christian expectation of the final, cosmic judgment.

The Aftermath of the Canon

If an author of the New Testament quoted it as scripture, why is 1 Enoch absent from the standard modern Bible?
As the centuries passed, both Rabbinic Judaism and the early Christian Church began to formalize their canons, rigidly deciding which books were truly authoritative. The Book of Enoch eventually fell out of favor in the Mediterranean world. Its bizarre, highly mythological narratives about fallen angels mating with human women to produce giants (the Nephilim) made later, more orthodox theologians increasingly uncomfortable. By the fourth century CE, it was widely excluded from the canonical lists of the Roman and Byzantine churches.
However, the text was never entirely lost to history. The Ethiopian Orthodox Tewahedo Church, which developed somewhat independently from Western theological disputes, never stopped reading it. Because their biblical canon is broader and more inclusive, they preserved the entire Book of Enoch in the Ge’ez language, treating it as fully canonical scripture to this day.
Ultimately, Jude’s quotation remains a powerful historical footprint. It reminds modern readers that the theological landscape of the first century was far messier, richer, and more diverse than the neatly curated Bibles sitting on modern shelves.
