What Are the Lost Books of the Bible?
The lost books of the Bible are ancient Jewish and early Christian texts composed alongside the biblical writings but excluded from most Christian canons. They include the deuterocanonical books, the pseudepigrapha attributed to figures like Enoch and Moses, and gnostic gospels such as Thomas and Judas — most never truly lost, only left outside the canon.
The table below gathers the most widely read of them — roughly when scholars think each was composed, which category it belongs to, and where it survives today.
| Text | Approx. composition | Category | Where it survives |
|---|---|---|---|
| 1 Enoch | 3rd c. BCE – 1st c. CE (composite) | Pseudepigrapha | Complete in Ge'ez; Aramaic fragments among the Dead Sea Scrolls |
| Jubilees | ~160-150 BCE | Pseudepigrapha | Complete in Ge'ez; Hebrew fragments at Qumran |
| Tobit | ~225-175 BCE | Apocrypha (deuterocanonical) | Septuagint; Aramaic and Hebrew fragments at Qumran |
| Judith | ~150-100 BCE | Apocrypha (deuterocanonical) | Septuagint; Catholic and Orthodox canons |
| Wisdom of Solomon | Late 1st c. BCE | Apocrypha (deuterocanonical) | Septuagint; Catholic and Orthodox canons |
| 1-2 Maccabees | ~124-100 BCE | Apocrypha (deuterocanonical) | Septuagint; Catholic and Orthodox canons |
| Gospel of Thomas | Late 1st–2nd c. CE | Gnostic (sayings gospel) | Coptic, Nag Hammadi (1945); Greek fragments from Oxyrhynchus |
| Gospel of Mary | 2nd c. CE | Gnostic | Coptic, Berlin Codex; Greek fragments |
| Gospel of Judas | ~130-170 CE | Gnostic (Sethian) | Coptic, Codex Tchacos (published 2006) |
| Shepherd of Hermas | ~90-150 CE | Apostolic Fathers | Codex Sinaiticus; Greek and Latin manuscripts |
| Epistle of Barnabas | ~70-135 CE | Apostolic Fathers | Codex Sinaiticus; Greek manuscripts |
You will hear these texts called "banned books" or "lost books," but no single authority sat down and struck a set of titles from an existing Bible. Canon formation was a centuries-long process in which different communities reached different conclusions — and the labels people use today rarely match what actually happened.
What makes these texts worth studying is what they reveal about the diversity of ancient Jewish and early Christian thought. The Book of Enoch shaped apocalyptic imagery that appears in the New Testament. The Gospel of Thomas preserves sayings of Jesus in a form that predates some canonical Gospel material. The deuterocanonical books — included in Catholic and Orthodox Bibles but absent from Protestant ones — were composed during the four centuries between the Old and New Testaments, a period of profound religious transformation.
Understanding these texts begins with understanding why the boundaries exist — and recognizing that those boundaries have never been universal.
Banned, Lost, or Non-Canonical? What the Labels Actually Mean
No universal authority ever banned a set of books from a single, agreed-upon Bible. The phrase "banned books of the Bible" implies a dramatic act of censorship — an institution examining a complete canon and striking out the texts it wanted suppressed. The historical reality is different, and it starts with three words that popular usage tends to collapse into one: banned, lost, and non-canonical.
A non-canonical text is simply one that a given tradition did not include in its canon. A lost text is one whose contents survived only in fragments or scattered references until rediscovery. A banned text is one an authority actively condemned. Most books people call "banned" were only ever non-canonical — they were never part of the collection they are imagined to have been expelled from.
Specific authorities did make judgments about specific texts. Irenaeus of Lyon, writing Against Heresies around 180 CE, argued that only four gospels — Matthew, Mark, Luke, and John — were legitimate, comparing them to the four winds and the four corners of the earth. Athanasius of Alexandria, in his 39th Festal Letter of 367 CE, produced the earliest surviving list matching the modern 27-book New Testament, sorting texts into canonical, useful-for-instruction, and rejected. The Gelasian Decree (traditionally attributed to Pope Gelasius I, though its 6th-century authorship is debated) catalogued the writings it deemed apocryphal.
None of these was a universal banning. Each was a regional authority drawing a line within its own sphere. In Lost Christianities (2003), Bart D. Ehrman emphasizes that such lists were aspirational rather than enforceable — communities in Syria, Egypt, and Ethiopia went on using texts that Rome or Alexandria rejected.
The "banned" framing also collapses two very different categories. Some texts were genuinely debated: the Shepherd of Hermas appears in the 4th-century Codex Sinaiticus alongside canonical books, and Revelation, 2 Peter, and James were classed as "contested" by Eusebius of Caesarea (c. 260-340 CE) in his Ecclesiastical History. Other texts were never serious candidates — the Gospel of Judas was condemned by Irenaeus within decades of its 2nd-century composition. Calling both categories "banned" implies they were all removed from a collection that once held them.
Elaine Pagels, whose The Gnostic Gospels (1979) shaped public understanding of early Christian diversity, has argued that texts like the gnostic gospels genuinely threatened the consolidation of orthodoxy by offering alternative models of authority — direct spiritual knowledge without institutional mediation, and leadership roles that challenged emerging hierarchies. The suppression was real, even if it was not a single act of book-banning. "Suppressed gradually by the winners of theological debates" is simply a harder story to tell than "banned by the Church."

The Apocrypha and Deuterocanonical Books
The terms "apocrypha" and "deuterocanonical" refer to the same set of texts, but the labels carry different theological weight. Protestants call them the Apocrypha (from the Greek apokryphos, "hidden"); Catholics and Orthodox Christians call them deuterocanonical ("second canon"), indicating that while they were accepted later than the primary Hebrew texts, they carry full canonical authority in those traditions.
These texts include Tobit, Judith, Wisdom of Solomon, Sirach (Ecclesiasticus), Baruch, 1 and 2 Maccabees, and additions to Esther and Daniel. Catholic Bibles include seven of these books; Orthodox Bibles include additional texts such as 1 Esdras, the Prayer of Manasseh, Psalm 151, and 3 Maccabees. All of them were composed during the Second Temple period (roughly 300 BCE to 100 CE) and were included in the Septuagint — the Greek translation of Jewish texts that served as the Old Testament for early Christians.
The Protestant Reformation brought the question of these books to a head. Martin Luther, following Jerome's earlier distinction, moved them to a separate section between the Old and New Testaments in his 1534 Bible, noting they were "useful and good to read" but not equal to canonical texts. The Council of Trent (1546) responded by formally defining the deuterocanonical books as part of the Catholic canon. The divide persists today: Catholic and Orthodox Bibles include these books; Protestant Bibles do not.
For a fuller account of the deuterocanonical books — what each one contains and how they became the subject of a five-century Protestant debate — the spoke articles below go deeper.
Canon Across Traditions
There is no single biblical canon. Different Christian traditions include different books, and the differences are not minor. The table below shows how four major traditions handle key categories of texts that fall outside the Protestant canon.
| Text Category | Protestant (66 books) | Catholic (73 books) | Eastern Orthodox (76-78 books) | Ethiopian Orthodox (81 books) |
|---|---|---|---|---|
| Tobit, Judith, Wisdom, Sirach, Baruch, 1-2 Maccabees | Not included | Included | Included | Included |
| Additions to Esther and Daniel | Not included | Included | Included | Included |
| 1 Esdras, Prayer of Manasseh, Psalm 151 | Not included | Not included | Included | Included |
| 3 Maccabees | Not included | Not included | Included | Included |
| 1 Enoch, Jubilees | Not included | Not included | Not included | Included |
| Meqabyan (1-3), Broader Ethiopian Canon | Not included | Not included | Not included | Included |
The Ethiopian Orthodox Tewahedo Church has the most expansive canon of any Christian tradition, with 81 books. This includes 1 Enoch and the Book of Jubilees — texts that no other major Christian tradition treats as canonical. The Ethiopian canon reflects a textual tradition that developed independently from the Western and Byzantine traditions, preserving texts in Ge'ez (classical Ethiopic) that were lost to European Christianity for centuries.
These differences are not abstract theological disputes. They reflect centuries of independent development, different manuscript traditions, and different criteria for what constitutes authoritative religious text. A Catholic Bible has seven more books than a Protestant Bible. An Ethiopian Orthodox Bible has fifteen more than a Catholic one. The question "what's in the Bible?" has never had a single answer.
The Pseudepigrapha: Texts Written in Ancient Names
The pseudepigrapha are ancient Jewish and early Christian texts attributed to biblical figures who did not compose them. The term comes from the Greek pseudepigraphos ("falsely attributed"), though scholars stress that the modern connotation of forgery is misleading. Writing under a revered name — Enoch, Moses, Solomon, Isaiah, Ezra, the twelve patriarchs — was a recognized literary convention, a way of honoring a tradition and claiming ancient authority rather than deceiving readers. Robert Kraft has described it as reflecting a communal sense of authorship in which ideas belonged to traditions, not individuals.
James Charlesworth, whose two-volume The Old Testament Pseudepigrapha (1983-1985) remains the standard collection, gathered 65 texts composed across roughly six centuries — from the 3rd century BCE to the 3rd century CE — in Hebrew, Aramaic, and Greek. Unlike the deuterocanonical books, which have a defined list, the pseudepigrapha is an open-ended scholarly category with no fixed canon. Its boundaries are a modern construction imposed on literature that its original communities did not sort in these terms.
Charlesworth's collection organizes these writings into recognizable literary forms:
- Apocalypses — visions of heaven, cosmic history, and divine judgment. The Book of Enoch (1 Enoch) is the most prominent, a composite work covering angelic rebellion, astronomical calculation, and the "Son of Man" figure that parallels language in the Gospels. 4 Ezra, composed after the destruction of the Jerusalem Temple in 70 CE, wrestles with divine justice amid catastrophe; Michael Stone's 1990 commentary calls it one of the most profound theological works of ancient Judaism.
- Testaments — farewell speeches attributed to biblical figures, such as the Testaments of the Twelve Patriarchs, each organized around a particular virtue or vice.
- Expansions of biblical narrative — the Book of Jubilees retells Genesis through early Exodus with a 364-day solar calendar, while the Life of Adam and Eve narrates the couple's life after their expulsion from Eden.
- Wisdom and prayer — the Wisdom of Solomon bridges Jewish wisdom traditions and Greek philosophical thought, and the Prayer of Manasseh imagines repentance extended to one of Judah's most notorious kings.
These texts fill a gap. Roughly four centuries separate the latest Hebrew Bible compositions (Daniel, around 165 BCE) from the earliest Christian writings (Paul's letters, around 50 CE), and the pseudepigrapha are the primary evidence for what Jewish communities were thinking during that interval. Ideas that would become central to Christianity — organized angels and demons, the resurrection of the dead, final judgment, messianic expectation, the Son of Man — developed here rather than in the Hebrew Bible.
The textual connections are direct. The letter of Jude quotes 1 Enoch by name (Jude 14-15). The cosmic warfare and angelic hierarchies of Revelation draw on Enochic tradition. Charlesworth has argued that it is impossible to understand the New Testament without understanding the pseudepigrapha — and at Qumran, 1 Enoch and Jubilees were copied alongside Deuteronomy and Isaiah, with no evident distinction in authority.
The Gnostic Texts: Alternative Early Christian Voices
The gnostic texts are early Christian writings that reflect theological perspectives significantly different from what became orthodox Christianity. Most were composed in the 2nd and 3rd centuries CE, and they were largely suppressed or lost until dramatic archaeological discoveries in the 20th century brought them back to scholarly attention.
The most significant discovery was the Nag Hammadi library, found in 1945 by an Egyptian farmer near the town of Nag Hammadi in Upper Egypt. The cache contained 13 codices with over 50 texts — gospels, apocalypses, and philosophical treatises that had been buried, probably by monks from a nearby monastery, in the late 4th century, around the time such texts were being condemned by orthodox authorities. Elaine Pagels's The Gnostic Gospels (1979) brought these texts to a wide audience, arguing that they reveal the diversity of early Christianity before orthodoxy consolidated.
The Gospel of Thomas, found at Nag Hammadi, is a collection of 114 sayings attributed to Jesus with no narrative framework — no birth, no miracles, no crucifixion, no resurrection. Some scholars, including Helmut Koester of Harvard, have argued that certain Thomas sayings preserve traditions independent of and possibly earlier than the canonical Gospels. The Gospel of Judas, published in 2006 from a Coptic manuscript discovered in the 1970s, reverses the traditional narrative by portraying Judas as Jesus's most trusted disciple, acting on Jesus's instructions. The Gospel of Mary Magdalene, surviving in fragmentary form, presents Mary as a recipient of privileged teaching from Jesus and a leader among the disciples — a portrait that stands in tension with the marginalization of her role in canonical accounts.
The gnostic gospels as a group challenge any assumption that early Christianity spoke with a single voice. They document alternative theologies, alternative leadership structures, and alternative understandings of Jesus's teaching — perspectives that existed alongside what eventually became orthodoxy, and that were actively debated before being suppressed. It is the central argument of Ehrman's Lost Christianities (2003) that the winners of these debates determined what counted as "heresy" and what counted as "truth" — and that the texts themselves tell a more complicated story than the labels suggest.
Why These Texts Still Matter
Exclusion from one canon never meant disappearance. The reasons a text was left out varied — dating, theology, or language — and so did its afterlife. Jerome, translating the Bible into Latin in the late 4th century, distinguished books preserved in Hebrew (the hebraica veritas) from those known only in Greek, treating the latter as secondary. That distinction is why Martin Luther later moved the deuterocanonical books to a separate section, and why the Council of Trent reaffirmed them as canonical for Catholics in 1546.
Yet the texts endured. The deuterocanonical books stayed in Catholic and Orthodox Bibles. 1 Enoch and Jubilees remained canonical in Ethiopia. The gnostic writings survived precisely because they were buried — the Nag Hammadi library, hidden in the Egyptian desert in the late 4th century and recovered in 1945, preserved over fifty texts that condemnation would otherwise have erased. The Dead Sea Scrolls, found beginning in 1947, carried 1 Enoch and Jubilees into the modern era in their oldest known form.
These are not footnotes to biblical history. They were composed by the same communities, in the same languages, during the same periods as the texts that entered the canon — addressing the same questions about origins, judgment, and revelation. Reading them alongside the canonical texts is how scholars reconstruct the full range of ancient Jewish and early Christian thought.
None of these texts was ever truly hidden. They survived in the Septuagint, among the Dead Sea Scrolls, in a jar buried near Nag Hammadi, and in the living canon of the Ethiopian church — waiting to be read alongside the sixty-six books that most Bibles settled on. Uncanon sets the same historical context before each of them: who composed it, when, and what it reveals about the crowded world that produced the Bible.
