The claim runs about 200 years ahead of the evidence.
Transformative knowledge requires lived participation and reverent ritual, not merely abstract speculation.
Iamblichus, De Mysteriis (c. 300 CE); Gregory Shaw, Theurgy and the Soul (1995).
Ritual invocation of divine hierarchies to purify the soul and achieve henosis.
Neoplatonic theurgy emerged in Late Antiquity through the Chaldean Oracles and the writings of Syrian philosopher Iamblichus as a ritual response to purely intellectual contemplation. In De Mysteriis Aegyptiorum, Iamblichus defended theurgy against Porphyry, arguing that human reason alone cannot transcend mortal limitations; rather, divine ascent (henosis) requires active communion with spiritual hierarchies through sacred sympathy, divine names, and material tokens (synthemata) implanted throughout creation.
Light
Humble reverence, participatory union with transcendent principles, and sacralizing material reality.
Shadow
Superstitious ritualism, prideful manipulation of spirits, and neglecting rational discernment.
