Mysterium Tremendum

The literature of religious experience abounds in references to the pains and terrors overwhelming those who have come, too suddenly, face to face with some manifestation of the mysterium tremendum. In theological language, this fear is due to the in-compatibility between man’s egotism and the divine purity, between man’s self-aggravated separateness and the infinity of God.
The numinous, the awe-inspiring element of religious experience, according to Otto ,evades precise formulation in words. Like the beauty of a musical composition, it is non-rational and eludes complete conceptual analysis.
Mysterium can be experienced in feelings that convey the qualitative content of the numinous experience. This content presents itself under two aspects: (1) that of “daunting awfulness and majesty,” and (2) “as something uniquely attractive and fascinating.” From the former comes the sense of the uncanny, of divine wrath and judgment; from the latter, the reassuring and heightening experiences of grace and divine love.
