Within the depth-psychology corpus, Satan occupies a position far exceeding that of a merely theological antagonist: the figure becomes a primary symbol through which writers map the dynamic structure of the psyche, the problem of evil, and the limits of monotheistic God-images. Jung’s treatment is foundational and multi-layered. In ‘Answer to Job’ and ‘Psychology and Religion: West and East,’ he traces Satan’s literary evolution from the Old Testament’s relatively minor adversarial figure, through Persian Ahriman and Egyptian Set, to the full-blown personification of the infimum malum demanded by Christianity’s elevation of God to summum bonum — a balance that, Jung insists, is not logical but psychologically inevitable. Critically, Satan functions within the divine economy itself: as God’s left hand in Clement of Rome, as elder son of Yahweh in Judaeo-Christian tradition, and as the catalyst for Job’s ordeal, which becomes the indirect cause of the Incarnation. Sanford extends this into pastoral psychology, reading Satan as the personification of collective demonic forces within human nature — those dissociative passions that sever the ego from its center. Armstrong historicizes the figure, documenting how the witch craze exteriorized collective shadow onto Satan-worship. The tension across the corpus is consistent: Satan must be understood as an intra-psychic and cosmological reality simultaneously, neither reduced to mere metaphor nor hypostatized naively.
