Abstract
From the perspective of Gabriel Marcel’s juvenile writings, most notably Fragments Philosophiques and Journal Métaphysique, this study discuss the first theoretical statute of the experience of God. This reflexive movement, strictly speaking, phenomenological-existential is based on the critique of absolute knowledge which, according to Marcel, is an unavoidable contradiction: at the same time, it affirms the being, it denies the being. What draws attention is the fact that such explanatory model is transposed and, therefore, applied using the classical formulation of the so-called problem of the existence of God, of which theodicy has one of the most eloquent and emblematic metaphysical discourses. For the young French thinker, God cannot be verified or justified as an ontological proof: God is the Inverifiable Absolute, since it has to be experienced in the act of faith, in the expression of love and grace.
