Nag Hammadi Books Reveal a Lost Christianity

For centuries, most of what survived about early Christianity’s rejected traditions came only from the writers who argued against them. A cache of ancient books found in Egypt changed that.

A Discovery Pieced Together After the Fact

The traditional account places the find in December 1945 near the cliffs of Jabal al-Tarif, north of Nag Hammadi in Upper Egypt. Later testimony centered on a farmer named Muhammad Ali al-Samman, who reportedly came across a large ceramic jar containing leather-bound papyrus books. No archaeologist witnessed the discovery, and Muhammad Ali himself gave varying accounts over time about exactly where and how the books surfaced. The manuscripts then passed through antiquities dealers and the Cairo market before scholars could study the full collection systematically, meaning some material may have gone undocumented before study began.

Thirteen Books, Dozens of Lost Texts

Known collectively as the Nag Hammadi codices, the manuscripts are conventionally counted as thirteen books, though the final codex survives only as loose leaves bound into another cover. According to the Claremont Coptic Encyclopedia, the collection contains 51 texts representing 45 distinct works, and 36 of those were previously unknown in any form. The books were copied in Coptic, mostly during the fourth century, from works believed to derive from earlier Greek originals. Scrap papyri reused in the cover of Codex VII carry dates of AD 341, 346, and 348, placing that particular binding no earlier than 348.

The Gospel of Thomas

The most famous text in the collection appears in Codex II. Unlike the four Gospels in the New Testament, the Gospel of Thomas tells no continuous story of Jesus’s life. It presents 114 sayings attributed to him, many introduced simply with the equivalent of Jesus said, with no birth narrative and no account of the crucifixion or resurrection. Greek fragments of the same text had already surfaced at Oxyrhynchus decades earlier, but Nag Hammadi provided the first essentially complete version, letting scholars finally see what those fragments belonged to.

Who Buried the Books, and Why

Nobody knows for certain who hid the codices or what they feared. One influential theory, strengthened by a 2024 study from Lund University scholar Paul Linjamaa, connects the books to the Pachomian monasteries active in the region during the fourth century. A tantalizing coincidence sits nearby in the historical record: in AD 367, Bishop Athanasius of Alexandria issued a letter listing exactly the 27 books that became the accepted New Testament, drawing a sharp line against other writings. No direct evidence ties that letter to the burial, but some scholars have wondered whether monks facing pressure over increasingly unacceptable books chose to hide rather than destroy them.
