Theurgy
Theurgy (Greek: theourgia, "divine work") denotes a tradition of ritual practices within late antique Neoplatonism, primarily developed by philosophers such as Iamblichus of Chalcis (c. 245–325 CE), aimed at invoking higher divine entities to purify the soul, facilitate its ascent through metaphysical hierarchies, and achieve henosis, or mystical union with the transcendent One.[1][2] Distinct from thaumaturgy, which involves practical wonder-working for material effects through personal will or lower spirits, theurgy emphasizes subordination to divine agency via symbolic rites, invocations, and consecrated objects like statues to effect spiritual transformation rather than earthly manipulation.[3][4] Emerging from the second-century Chaldean Oracles, attributed to Julian the Theurgist, these practices integrated Platonic philosophy with mystery cult elements, positioning ritual as essential complement to intellectual contemplation for overcoming material embodiment's limitations.[2][1] Iamblichus defended theurgy in works like On the Mysteries against critics such as Porphyry, arguing that divine sympathy with material symbols enables gods to descend and elevate the practitioner, a view influencing subsequent Neoplatonists like Proclus and shaping pagan resistance to Christian dominance until the fifth century.[1][5] While empirical validation of its causal claims remains absent, theurgy's emphasis on embodied ritual over abstract theology marked a pivotal shift in esoteric traditions, prioritizing participatory divine encounter.[1]
