Anti-Jewish Gnosticism started in Judaism itself it first came about from a rejection of the law of Moses this can be seen from the books of Maccabees
1 Maccabees 1:11 In those days lawless men came forth from Israel, and misled many, saying, "Let us go and make a covenant with the Gentiles round about us, for since we separated from them many evils have come upon us."
[12] This proposal pleased them,
[13] and some of the people eagerly went to the king. He authorized them to observe the ordinances of the Gentiles.
[14] So they built a gymnasium in Jerusalem, according to Gentile custom,
[15] and removed the marks of circumcision, and abandoned the holy covenant. They joined with the Gentiles and sold themselves to do evil.
[16]
According to 2 Macc 4:10 When the king had granted this and Jason had taken possession of his office, he immediately made his fellow citizens change to the Greek way of life. 11 He set aside the customs established for the Jews by royal generosity, negotiated through John the father of Eupolemus (the one who had made the official journey to secure friendship and alliance with the Romans). He abolished the lawful government and introduced customs contrary to the law.
This is the creation of Anti-Jewish Gnosticism
The Origins of Gnosticism
Gnosticism, broadly defined, refers to a series of religious movements that emphasized secret knowledge (gnosis) as the path to salvation, often viewing the material world as flawed or corrupt. While it reached its height in the 2nd and 3rd centuries CE through Christianized Gnostic sects like the Valentinians and Sethians, the origins of Gnosticism trace back to a much earlier time—within Jewish Hellenistic circles influenced by Greek philosophy.
Two early witnesses, Josephus and Philo of Alexandria, offer piercing criticisms of what can rightly be seen as the seeds of early Gnosticism—individuals among the Jews who blended Greek philosophical speculation with the Hebrew Scriptures, leading to mystical reinterpretations that deviated sharply from the Law.
In Against Apion (2.256–257), Josephus laments:
“Some among us have been so delighted with Greek culture that they have not only neglected their own laws, but have laughed at them and even attempted to misinterpret them with forced allegories, for the sake of Greek philosophy.”
Here, Josephus describes a trend among certain Hellenized Jews who abandoned the traditional, literal interpretation of the Hebrew Scriptures in favor of allegorized, philosophical reinterpretations. These figures, in Josephus’s eyes, betrayed the integrity of the ancestral Law in their attempt to harmonize Judaism with the dominant intellectual currents of the Greco-Roman world.
Philo, a Jewish philosopher deeply immersed in both Torah and Platonic thought, also distinguishes himself from those who went too far. In On Dreams (1.29–31), he writes:
“Some, boasting of wisdom falsely so-called, pervert philosophy into a cloak for impiety, weaving together fictions and monstrous tales, daring to call their own baseless opinions divine oracles… mixing plausible doctrines with ridiculous delusions.”
This scathing rebuke shows that even within Philo’s own allegorical approach, there were individuals or movements he deemed to be going beyond the bounds of reason and reverence. These "boasters" likely represent a form of proto-Gnosticism—combining Jewish traditions with speculative myths, secret teachings, and the language of divine revelation.
Jewish Roots of Gnostic Thought
The historical setting that gave rise to Gnosticism was the cultural melting pot of Hellenistic Judaism, especially during and after the time of Antiochus IV Epiphanes (2nd century BCE). The trauma of foreign oppression, combined with exposure to Platonic dualism and mystery religions, led some Jewish thinkers to recast their theology.
Groups like the Essenes and the Therapeutae already show elements of this development:
-
A focus on asceticism and ritual purity
-
A dualistic worldview of light and darkness
-
A preference for symbolic and allegorical interpretations of the Law
-
A view of the material world as something to be escaped or transcended
Such groups, though still rooted in Jewish tradition, were beginning to reframe the Scriptures in ways that resemble the Gnostic mythos that would later fully emerge.
One of the most revealing facts about early Gnosticism is its reuse and reinterpretation of Jewish apocalyptic literature, especially texts like 1 Enoch, In this text, divine knowledge is imparted by angels, rather than through the direct revelation of the Mosaic law, and the origins of evil are explained through the descent of the Watchers and their impartation of forbidden knowledge. This rejection of the Torah and its institutions, such as the priesthood and sacrifices, provides an early critique of traditional Jewish practices.
In Enoch 89:73, the text states:
"Upon the return from exile, the people reared up that tower (the temple) and they began again to place a table before the tower, but all the bread on it was polluted and not pure."
This rejection of the temple and its rituals aligns with the critique of the established religious order, an attitude that would later characterize Gnostic thought, which saw the material world and its institutions as corrupt and inferior to the higher, spiritual realm.
It was from this foundation that the Sethian Gnostics would arise, venerating Seth as the father of a spiritual race and interpreting the Hebrew God as a lesser being called Yaldabaoth. These views were born in opposition to Judaism, as speculative, mystical rejections of its laws and traditions.
From Jewish to Christian Gnosticism
Early Gnostic texts like Eugnostos the Blessed are entirely devoid of Christian elements, showing that Gnostic theology originated outside the Christian movement. This text, with its complex theology of divine emanations, unknowable principles, and Aeons, later formed the core of the Christianized Sophia of Jesus Christ, where the same teachings are now placed in the mouth of the resurrected Jesus.
This shift represents the Christianization of Jewish mystical speculation. Gnosticism did not begin as a Christian heresy—it began as a radical, mystical form of Judaism influenced by Greek philosophy. It only became Christian in the 2nd century when figures began to insert Jesus into their already-developed systems.
Texts like the Apocryphon of John show the fusion point. The risen Christ appears to John the apostle, revealing the true history of the world. In this narrative, the Creator God of Genesis is reinterpreted as an ignorant or arrogant entity called Yaldabaoth, while the true Father remains hidden in the Pleroma. This represents a complete departure from Judaism, where its symbols and teachings were distorted through Hellenistic philosophy and apocalyptic myths, later being reshaped to fit a Christianized framework.
Conclusion
The origins of Gnosticism lie in a fusion of Jewish apocalyptic expectation, Greek metaphysics, and allegorical scriptural interpretation. The critiques of Josephus and Philo show that even before the Christian era, certain Jewish thinkers were blending Torah with philosophy, creating systems that emphasized secret knowledge, allegory, and speculative theology.
Later, these Jewish Gnostic streams would be absorbed into emerging Christianity, where the figure of Jesus was interpreted not just as a teacher or Messiah, but as a heavenly revealer of mysteries. But the roots are older—planted in the soil of Second Temple Judaism, watered by Greek thought, and criticized by Josephus, Philo, and later Paul, who warned Timothy to “avoid the profane babblings and contradictions of what is falsely called knowledge (gnosis)” (1 Timothy 6:20).
Gnosticism did not emerge as a mystical evolution from within Judaism but rather as a reaction to the rejection of the Torah and the customs of Israel. Beginning with the influence of Hellenistic culture under rulers like Antiochus IV Epiphanes, many Jews started to abandon their ancestral laws in favor of Greek philosophy and cultural practices. This rejection of the Law, which is evident in sources such as the Book of Maccabees, laid the groundwork for early Gnostic thought. The Gnostics adopted elements of Greek philosophy and myth, creating speculative doctrines and claiming access to secret knowledge, all while disregarding the traditional Jewish understanding of the Torah. Their approach was marked by disdain for the Jewish law, mixing Greek thought with mystical teachings that contradicted the teachings of Israel.
