Gnostics did not reject the Bible — they reread it. Using allegorical interpretation, they found in Genesis, the Psalms, and Paul's letters a hidden cosmological teaching that orthodox Christians had missed. The God of the Old Testament was identified as the Demiurge; the serpent in Eden became a liberator; Paul's "rulers of this age" (1 Corinthians 2:6-8) became the Archons. The Gospel of John — with its prologue about the divine Word — was the most favoured Gnostic scripture in the entire New Testament.
How Gnostics Read Scripture
The common assumption that Gnostics rejected the Bible is incorrect. Most Gnostic teachers — especially the Valentinians — engaged intensively with Jewish and Christian scripture, using the same allegorical methods of interpretation developed by Philo of Alexandria and later by Origen. The difference was not whether to interpret scripture allegorically but what the allegory revealed.
For orthodox Christians, allegorical interpretation pointed toward moral and theological truths consistent with the emerging mainstream theology. For Gnostics, the same allegorical reading revealed a hidden cosmological teaching: evidence of the true God above the creator, the divine spark within humanity, and the path of gnosis toward liberation.
Genesis — The Most Contested Text
Genesis was the single most important and contested biblical text in Gnostic interpretation. Multiple Nag Hammadi texts — the Secret Book of John, the Reality of the Rulers, On the Origin of the World — retell the Genesis creation narrative from a Gnostic perspective:
- Genesis 1:1-2 ("In the beginning God created...") — the "God" here is the Demiurge, not the true divine being. The "formless void" (tohu wa-bohu) is the chaos into which Sophia's passion has fallen.
- Genesis 1:26 ("Let us make man in our image") — the Demiurge speaks to his Archons. The "image" that inspires them is actually the divine Anthropos (heavenly Human) reflected in the waters of chaos — they create an earthly human body to trap a divine spark they cannot properly contain.
- Genesis 2:7 (God breathes life into Adam) — the Demiurge accidentally breathes his own divine power into the human he creates, inadvertently giving the human more spiritual capacity than the Demiurge himself possesses.
- Genesis 3 (The serpent and Eden) — the serpent is the divine Sophia, or a divine agent, who gives Eve the gnosis the Demiurge has forbidden. Eating the fruit is not sin but liberation. The Demiurge's punishment of Adam and Eve reveals his fear: "the man has become like one of us" (Genesis 3:22) — exactly what the divine wanted for humanity.
And he blew into his face the spirit, which is the power of his mother; he did not know this, for he exists in ignorance. And the power of the mother went out of Yaldabaoth into the natural body, which they had fashioned after the image of the one who exists from the beginning.
Paul — The Gnostic Apostle
Gnostic teachers — especially Valentinus and his school — regarded Paul as their primary apostolic authority, arguing that he preserved a secret inner teaching alongside his public one. Several Pauline passages lent themselves naturally to Gnostic interpretation:
- 1 Corinthians 2:6-8 — "We speak wisdom among the perfect... the wisdom of this age or of the rulers (archons) of this age who are perishing." The Gnostics read "rulers of this age" as the Archons — the planetary rulers who govern the material world. Paul knew about them.
- 2 Corinthians 4:4 — "The god of this age has blinded the minds of unbelievers." The Gnostic reading: "the god of this age" is the Demiurge, not the true God.
- Galatians 4:8 — those "enslaved to beings that by nature are not gods" — the Archons, again.
- 1 Corinthians 15:44 — "There is a natural body and there is a spiritual body." The Valentinians used this to support their three-tier anthropology (pneumatic/psychic/hylic).
Heracleon — the first Valentinian to write a biblical commentary — produced an extensive commentary on the Gospel of John that interpreted it entirely through a Valentinian lens. His work, preserved in quotes by Origen (who was arguing against it), shows the sophistication of Gnostic biblical exegesis.
The Gospel of John — The Gnostic Gospel
Among all the New Testament writings, the Gospel of John was the most naturally amenable to Gnostic interpretation. Its prologue — "In the beginning was the Word (Logos), and the Word was with God, and the Word was God" — maps directly onto Gnostic Aeon cosmology: the Logos is one of the divine emanations of the Pleroma. The Gospel's themes of light vs darkness, knowledge vs ignorance, the heavenly origin of Jesus, and his descent from and return to the Father all read naturally through a Gnostic lens.
The Gospel of Truth (attributed to Valentinus) cites the Gospel of John more than any other scripture. The Gospel of Philip and the Secret Book of John both engage extensively with Johannine themes. Pagels's The Johannine Gospel in Gnostic Exegesis (1973) — her scholarly work before The Gnostic Gospels — documented this in detail: the Gospel of John was the Gnostic gospel par excellence.
The Old Testament — Gnostic Attitudes
Gnostic attitudes toward the Old Testament varied by tradition and were more nuanced than simple rejection:
- Sethians — engaged intensively with Genesis, retelling it from a Gnostic perspective. Used the Psalms as hymns of the fallen soul crying out to the true God (as in the Pistis Sophia).
- Valentinians — allegorised the Old Testament extensively. Ptolemy's "Letter to Flora" distinguishes three parts of the Mosaic Law: that given by God (the true God, partially), that given by Moses himself, and that given by elders — only some of which is binding.
- Marcionites — rejected the Old Testament entirely as the work of the Demiurge, not the supreme God. The most radical position.
Did Gnostics believe the Old Testament was evil?
Not uniformly. Marcionites rejected it entirely. Sethian Gnostics engaged with it intensively but reinterpreted it, reading the God of the Old Testament as the Demiurge rather than the true God. Valentinians used allegorical interpretation to find deeper meanings consistent with their theology. The range of Gnostic attitudes toward the Old Testament was wide — from near-total rejection (Marcion) to intensive allegorical engagement (Valentinus).
Is the serpent in Genesis a positive figure in Gnosticism?
Yes, in most Gnostic readings. The serpent is the agent who gives humanity the knowledge (gnosis) the Demiurge was withholding. In some texts (On the Origin of the World, the Reality of the Rulers) the serpent is explicitly identified with the divine Sophia descending to liberate humanity. The Naassenes, the Ophites, and other Gnostic sects venerated the serpent as a symbol of divine wisdom. See our full article on Gnostic symbols for the serpent's cosmological meaning.
