Atonement occupies a complex and contested position in the depth-psychology corpus, functioning simultaneously as a theological datum, a mythological archetype, and a psychological process requiring reinterpretation. The term appears across at least three distinct registers. In the biblical-theological register, represented most systematically by Thielman, atonement designates the sacrificial mechanism by which Christ’s death addresses the universal condition of sin, drawing on the Suffering Servant pattern, the Day of Atonement ritual, and covenantal frameworks across the canonical literature. In the comparative-mythological register, Campbell and Miller read atonement theories as thinly veiled polytheistic narratives — the ransom theory echoing Zeus and Prometheus, penal theories shadowing Trojan War epics — thereby dissolving Christian uniqueness into recurring mythic structures. Most critically for depth psychology proper, Jung subjects the orthodox atonement doctrine to a decisive inversion: he argues that the wrong may belong not to humanity before God but to God before humanity, repositioning the Cross as divine reparation rather than human debt-payment. Peterson, drawing on Jung, further psychologizes the term as ‘at-one-ment’ — the individuation process by which the ego–Self split, inaugurated in Eden, is healed through ego-dissolution. Armstrong’s rabbinic voice adds a further tradition: acts of loving-kindness as atonement’s functional substitute after the Temple’s destruction. Together these voices reveal atonement as a site where soteriology, depth psychology, and comparative mythology productively collide.
