Mysterium Tremendum

The mysterium tremendum stands as one of the most consequential concepts imported from the phenomenology of religion into depth-psychological discourse. Rudolf Otto coined the term in Das Heilige (1917) to name the irreducibly non-rational core of religious experience: the overwhelming, awe-inducing, and finally ungraspable character of the holy as it seizes consciousness. Within the depth-psychology corpus, the term travels far from its origins. Jung appropriates it as shorthand for the numinous quality of archetypal encounters — the dread-laden autonomy of unconscious contents that can neither be willed nor domesticated by the ego. Campbell recasts it as the existential shock that myth is uniquely equipped to mediate, placing it at the centre of the mythological function: humanity’s need to absorb and orient itself toward the terror of mortality and the groundlessness of existence. Eliade uses Otto’s framework as his point of departure for the sacred/profane distinction. Hillman, characteristically, democratises and miniaturises it — the tremendum need not arrive in cosmic scale; it may come as the brush of an insect wing. Burkert, by contrast, explicitly refuses to apply mysterium tremendum to Greek hieros, insisting the term implies an inwardness alien to the Greek sacred. The key tension running through the corpus is whether the mysterium tremendum names a universal, irreducible datum of consciousness or a culturally constructed interpretive category.

its original designation as ‘mysterium tremendum’ that it at the same time exercises a supreme ‘fascination’. And this its dual character, as at once an object of boundless awe and boundless wonder, quelling and yet entrancing the soul, constitutes the proper positive content of the ‘mysterium’

Otto establishes the mysterium tremendum as inherently bipolar — simultaneously a source of overwhelming dread and irresistible fascination — constituting the full positive content of numinous experience.

the ‘feeling of reality’, the feeling of a ‘numinous’ object objectively given, must be posited as a primary immediate datum of consciousness, and the ‘feeling of dependence’ is then a consequence, following very closely upon it

Otto situates the mysterium tremendum as the primary datum from which the feeling of creaturely dependence is derived, anchoring the numinous in an objective givenness prior to reflection.

It is the absolute ‘numen’, felt here partially in its aspect of ‘maiestas’ and ‘tremendum’. And the reason I introduced these terms above to denote the one side of the numinous experience was in fact just because I recalled Luther’s own expressions

Otto traces the etymological and experiential roots of tremendum directly to Luther’s language of divine majesty and consuming wrath, grounding the concept in concrete religious biography.

he concentrated chiefly on its irrational aspect. For Otto had read Luther and had understood what the ‘living God’ meant to a believer. It was not the God of the philosophers… it was a terrible power, manifested in the divine wrath.

Eliade frames Otto’s mysterium tremendum as a recovery of the pre-rational terror at the heart of religious experience, distinguishing it decisively from philosophical and moral conceptions of the divine.

the tremendum element in Christian mysticism is subdued, it is not entirely lacking. It remains a living factor in the Caliga and the altum silentium, in the ‘Abyss’, the ‘Night’, the ‘Deserts’ of the divine nature, into which the soul must descend

Otto traces the tremendum element through Christian mysticism, showing how the abyss, night, and annihilation motifs preserve the overwhelming character of the numinous even in its most refined contemplative forms.

The ‘shudder’ reappears in a form ennobled beyond measure where the soul, held speechless, trembles inwardly to the furthest fibre of its being… It has become a mystical awe, and sets free as its accompaniment… that ‘creature-feeling’

Otto traces the evolution of the tremendum from primitive shudder to mystical awe, showing how the bodily-somatic dimension of the mysterium tremendum persists even in its highest devotional forms.

in adulthood, to be prepared to face the mystery of death: to absorb the mysterium tremendum of being: for [humans], like no other animal,…[know] that [they] too will die

Campbell appropriates the mysterium tremendum as the existential horizon that myth must address — the uniquely human confrontation with mortality as the ground of all mythological function.

Noel’s analysis of Campbell confirms that the mysterium tremendum functions in Campbell’s thought as the transcendental dimension of myth, exceeding mere sociological imprinting by confronting humans with death.

religious feelings may be attached directly to the deity, as in Otto’s mysterium tremendum, or to the beliefs, rituals, practices, symbols, and communities built around God

Pargament positions Otto’s mysterium tremendum as one pole of a spectrum of religious feeling, contrasting direct numinous encounter with the mediated affect produced by religious practices and communities.

No special feeling is implied or to be evoked, neither mysterium tremendum nor fascinans. It would also be totally impossible to call a god himself hieros

Burkert explicitly denies that the Greek concept of hieros carries the experiential charge of Otto’s mysterium tremendum, marking a significant cross-cultural limit to the term’s applicability.

Theology says the divine is a tremendum, but a tremendum can come in small tremulous ways, a mere tremor, a shake, brush, shrug — the swift reaction to an insect.

Hillman radically scales down the tremendum, arguing that the numinous encounter need not be cosmically overwhelming but may arrive in the smallest, most easily dismissed somatic reactions.

The numinous experience of the individuation process is, on the archaic level, the prerogative of shamans and medicine men; later, of the physician, prophet, and priest; and finally, at the civilized stage, of philosophy and religion.

Jung situates the numinous — the psychological equivalent of the mysterium tremendum — as the transformative core of the individuation process across all historical stages of human development.

in his battles with ‘desperatio’ and with Satan, in his constantly recurring religious catastrophes and fits of melancholy, in his wrestlings for grace, perpetually renewed, which bring him to the verge of mental disorder, in all these there are more than merely rational elements at work

Otto reads Luther’s psychological crises as live evidence of the non-rational tremendum operating within individual religious consciousness, approaching what depth psychology would later term numinous encounter.

Archetypal inner objects are numinous, overwhelming, and mythological. They exist in the psyche as antinomies or opposites, which gradually come together in the unconscious as dual unities which are alternately blissful or terrifying

Kalsched implicitly evokes the structure of the mysterium tremendum — its dual character of terror and fascination — in describing the numinous, overwhelming quality of archetypal objects encountered in early trauma.
