What is Gnosticism?


Listen Later

What if one of the oldest heresies in Church history never really died — but just changed names?

In this episode, we explore what Gnosticism actually is: not just a strange ancient idea, but a worldview that still shapes how modern people think about truth, identity, and salvation. We’ll define Gnosticism in its original context, trace its development into esoteric and Hermetic forms, and uncover how it continues to influence everything from New Age spirituality to revolutionary politics.

Far from being a relic of the past, Gnosticism is alive and well — often hiding in plain sight.

Topics covered:

What the word gnosis means, and why it matters

Gnosticism’s core beliefs: dualism, hidden knowledge, salvation through awakening

The difference between Gnosticism, esotericism, and Hermeticism

How Gnosticism reappears in today’s ideologies, technologies, and spiritual movements

Why this matters for Christians — and what the Gospel offers instead

This is the first in a series exploring the deep roots of modern confusion — and why the Church’s ancient witness still speaks today.
