What Is Gnosticism?

**What Is Gnosticism?**

Gnosticism is a Christian philosophical and theological movement that emerged in the early centuries of the Common Era, growing out of Jewish philosophical traditions and shaped by the surrounding Hellenistic world. While there is no single creed that defines Gnosticism, the various Gnostic systems share a common focus on *gnosis*—a Greek word meaning "knowledge." This knowledge, however, is not merely intellectual or doctrinal; it is experiential and transformative. To "know oneself" is, in the Gnostic worldview, to begin the process of liberation from the powers that bind the soul to ignorance and decay.

Though Gnosticism took many forms, two of its most influential expressions are found in the Sethian and Valentinian schools. Each of these developed complex mythologies and cosmologies to describe the nature of reality, the origin of the world, and the means of salvation. At its heart, Gnosticism is about the pursuit of wisdom and the recognition of divine truths hidden beneath the surface of conventional religion and scripture.

### Roots in Jewish Philosophy and Allegory

The earliest seeds of Gnostic thought can be traced to Jewish communities grappling with Greek philosophy during the Hellenistic period. Influential figures like Philo of Alexandria employed allegorical methods to harmonize Hebrew Scripture with Platonic metaphysics. This tendency to read sacred texts symbolically, rather than literally, laid the groundwork for Gnostic reinterpretations of the creation story, the role of divine beings, and the nature of human identity.

However, Gnosticism moved beyond Philo's rational synthesis. Where Philo still revered the Mosaic Law and saw Greek philosophy as compatible with Jewish faith, Gnostics took a more radical turn. They began to question whether the God of the Hebrew Bible—the creator of the physical world—was truly the Highest Deity. In many Gnostic systems, he is not. Rather, he is a subordinate being, a lesser power ignorant of the true, invisible, and transcendent God above him.

### Know Thyself

Central to Gnostic teaching is the ancient maxim: *Know thyself*. This self-knowledge is not psychological in the modern sense but ontological—it concerns one's true origin and nature. According to Gnostic myth, the human being contains a divine spark, a remnant of the heavenly world, trapped in a corrupt physical body within a hostile cosmos. This spark is often said to originate from the Aeons, emanations or aspects of the divine fullness (Greek: *Pleroma*).

To know oneself, then, is to realize that one is not truly part of this world. One’s body and social identity are not the whole story. Beneath them lies a divine element that yearns for reunion with its heavenly source. This insight is the beginning of liberation. As the Gospel of Thomas famously states: “If you bring forth what is within you, what you bring forth will save you.”

### The Study of the Aeons

In Gnostic cosmology, the divine realm—the Pleroma—is inhabited by Aeons. These are not gods in the polytheistic sense, but rather divine attributes or emanations of the Most High. They represent qualities such as Truth, Wisdom (Sophia), Grace, and Light. The Aeons together express the fullness of the invisible God, much like rays express the nature of the sun.

Sophia, the Aeon of Wisdom, plays a crucial role in many Gnostic myths. In some stories, she attempts to understand or approach the ineffable God on her own, resulting in a fall from the Pleroma. This fall leads to the creation of a flawed being—often identified as Yaldabaoth or the Demiurge—who then creates the material world in ignorance or arrogance. Thus, the study of the Aeons and their interactions is central to understanding how the world came to be and how humanity can return to the divine fullness.

### A God Above God

One of the most provocative aspects of Gnosticism is its doctrine of a god above God. For the Sethians, this means understanding that Yaldabaoth—the creator god of Genesis—is not the true Highest God. Yaldabaoth is depicted as a blind and arrogant being who falsely claims to be the only god. In reality, he is a product of Sophia’s error, a lesser being who fashions the cosmos not out of benevolence but out of ignorance.

The Valentinians, while somewhat more moderate in tone, also teach that the creator god (the Demiurge) is not the ultimate source of being. He is a necessary but limited force, responsible for organizing the material world but unaware of the higher truths revealed in Christ. In this view, Christ comes not to fulfill the Law but to reveal the truth about the divine world above the creator's domain.

This distinction between the creator and the transcendent God explains the Gnostic suspicion of the material world. The physical realm is not inherently evil, but it is flawed and impermanent—a shadow of the higher, unchanging reality. Salvation, then, is not about moral improvement or ritual obedience but about awakening to one’s true origin and destiny.

### Conclusion

Gnosticism is a deeply spiritual and philosophical movement that seeks to answer life's most profound questions: Who am I? Where did I come from? Why am I here? What is wrong with the world, and how can it be set right? Through allegory, myth, and mystical insight, Gnosticism teaches that salvation comes through knowledge—knowledge of the divine, knowledge of the cosmic order, and most importantly, knowledge of oneself.

While Gnosticism was eventually labeled heretical by the emerging Catholic Church, its influence lingers in modern spiritual movements, esoteric traditions, and philosophical inquiries. At its core, it continues to invite seekers to look beneath the surface of conventional belief and to awaken to the hidden truths of existence.
