Philo-Judæus of Alexandria

In Short

Norman Bentwich presents an intellectual biography of Philo-Judæus, the first-century Alexandrian philosopher who sought to synthesize Hebrew scripture with Greek metaphysics. Writing at a crucial historical intersection, Philo uses allegorical interpretation to defend Jewish monotheism and law against Hellenistic critics while offering a universal moral code to the broader world. Though his writings were later neglected by mainstream rabbinic tradition and absorbed into Christian theology, Bentwich demonstrates that Philo’s loyalty to the Mosaic law remained absolute, making his religious philosophy an enduring testament to the creative expansion of the Hebrew mind under the influence of global culture.

The Story

The intellectual arc of the work traces the historical necessity, flourishing, and ultimate fate of Hellenistic Judaism as embodied in the life and writings of Philo of Alexandria. Born around 20 B.C.E. into a prosperous community in Egypt, Philo comes of age during an era of profound cultural cross-pollination, where Greek philosophy and Roman power meet the ancient traditions of Israel. The synthesis begins with the creation of the Septuagint, the Greek translation of the Hebrew Scriptures, which allows Jews to conceptualize their faith through Greek intellectual tools while exposing Gentile readers to Mosaic thought.

Philo’s early intellectual life consists of mastering Greek academic forms, composing philosophical exercises on conventional topics like providence and liberty, and immersing himself in the writings of Plato and the Stoics. However, as anti-Semitic tensions simmer in Alexandria—fueled by hostile Stoic agitators like Apion and the Egyptian populace—Philo steps forward as the intellectual defender of his community. He writes extensive apologetic works, demonstrating that Moses is the supreme lawgiver and ideal human, whose divine law embodies a universal code capable of bringing peace to all humanity. Attached to his broad moral treatises are passionate defenses of the law and calls to welcome converts without fear.

When the tyrannical Emperor Gaius orders his own image placed in religious sanctuaries, triggering brutal riots in Alexandria, Philo’s contemplative life is interrupted. He travels to Rome at the head of a diplomatic delegation to plead for Jewish religious liberty. Following the crisis, Philo dedicates his mature years to his masterwork: a massive allegorical commentary on the Scriptures. Through this method, he interprets biblical narratives not merely as literal history or physical miracles, but as deep spiritual allegories of the soul’s journey toward divine wisdom. Central to his theology is the concept of the Logos—the divine reason and active effluence of God that bridges the gap between an infinite Creator and mortal humanity.

The closing arc of the book examines Philo’s historical legacy and ultimate estrangement from rabbinic Judaism. Following the rise of Christianity and the destruction of the Jewish state, the Christian Church appropriates Philo’s Logos doctrine, transforming his philosophical monotheism into the dogmatic framework for the Incarnation. Fearing total spiritual disintegration and the loss of their distinct identity, the rabbinic authorities in Palestine and Babylon turn away from Greek wisdom, cutting Alexandrian literature out of traditional Jewish memory. Philo’s writings vanish from Jewish thought for over a thousand years until rediscovered during the Renaissance by Azariah dei Rossi, who recognizes that beneath his Greek terminology, Philo remained thoroughly committed to the sanctity of the Torah.

How It Unfolds

The Hellenistic cradle The book begins by detailing the historical environment of Alexandria, where the translation of the Hebrew Bible into Greek sets the stage for a dramatic intellectual encounter between Hebraic faith and Greek philosophy.

The defender steps forward Faced with bitter anti-Semitic campaigns led by local Stoic philosophers and violent civic unrest under the Emperor Gaius, Philo leaves his quiet academic life to defend the legal and moral integrity of the Jewish people.

The Mosaic gospel In his biographical and ethical writings, Philo presents Moses as the ultimate philosopher-king and lawgiver, arguing that the divine Torah provides a permanent, natural code of conduct for all human societies.

The allegorical synthesis Philo constructs his elaborate commentary on Scripture, employing allegorical interpretation to reveal hidden metaphysical truths and introducing the concept of the Logos as the connecting effluence between God and human reason.

The divergence of paths The arc concludes with the historical afterlife of Philo’s thought, showing how his doctrines were embraced by early Christian theologians while being deliberately excluded by rabbinic tradition to preserve the national purity of Judaism.

The People

• Philo-Judæus: The primary subject of the work, an Alexandrian Jewish philosopher who seeks to demonstrate that the revealed law of Moses contains the highest expressions of universal truth and moral virtue. He desires to protect his community from assimilation and external hostility, facing the constant challenge of bridging two distinct intellectual worlds before ending his life as the grand reconciler of faith and reason.
• Moses: The central figure in Philo’s philosophical system, viewed not merely as a historic leader, but as the supreme interpreter of divine law, the perfect human, and the ultimate link between human reason and divine wisdom.
• The Stoic Polemicists (Apion and Chæremon): Literary agitators in Alexandria who write hostiles attacks against Jewish customs and morality. They stand as the main intellectual adversaries threatening the social standing and safety of the Alexandrian Jewish community.
• The Rabbinic Authorities: The spiritual leaders of Palestinian and Babylonian Judaism who seek to safeguard the core identity of the Jewish people. They face the threat of spiritual chaos caused by Greek syncretism and ultimately decide to excise Greek wisdom from Jewish tradition to preserve the integrity of the Torah.

In Its Own Voice

"The weak thorn-bush, which was not consumed by the fire, is the image of the idea of Israel, which almost cries to the people in their misfortune: 'Do not despair! Your weakness is your strength, and by it you shall wound race after race.'"

— In his reading of the burning bush at Horeb, Philo extracts a spiritual symbol of Israel's miraculous survival amid constant worldly persecution.

"Nor is the Logos cupbearer only, but it is itself the pure draught, itself the joy and exultation, itself the pouring forth and the delight, itself the ambrosial philtre and potion of bliss."

— Demonstrating his rich use of imagery, Philo describes the divine Logos as both the bearer and the substance of spiritual joy in the human soul.

"All that is good in Philo agrees with our law."

— The sixteenth-century Jewish scholar Azariah dei Rossi sums up his reassessment of Philo after centuries of neglect by traditional authorities.

What It's Really About

The book explores the tense relationship between cultural assimilation and religious fidelity. At its core, it asks whether a tradition can engage deeply with foreign intellectual frameworks without losing its essential identity. Bentwich argues that Philo's attempt to reconcile Hebrew monotheism with Greek philosophy was not a compromise of Jewish integrity, but a vital expansion of the Hebrew mind. The text examines how ideas evolve across cultural boundaries, highlighting the tragedy of how Philo's allegorical methods were used by external movements to reject the Mosaic law he loved, leading his own community to disown his legacy in order to ensure their spiritual survival.

Why Read It Today

This study offers a masterful look into the early intersection of Western philosophy and Semitic faith. Readers interested in religious history, classical antiquity, and the history of ideas will appreciate Bentwich's clear, balanced prose and detailed contextualization. The book provides a thoughtful examination of how a minority culture maintains its core values while participating in a cosmopolitan world.

Reading the work requires patience, as it frequently engages with complex philosophical terminology, ancient theological debates, and historical contexts that assume a basic familiarity with classical anti-Semitism and early Hellenistic schools. The text occasionally reflects early twentieth-century academic perspectives on historical development and religious evolution. Nevertheless, it remains a deeply rewarding read for anyone curious about the roots of Western religious thought, offering an illuminating portrait of a forgotten thinker who stood at the crossroads of the ancient world.
