We Only Know a Limited Sketch of God

Our knowledge of God is the imprint of the knowledge God has of himself but always on a creaturely level and in a creaturely way. The knowledge of God present in his creatures is only a weak likeness, a finite, limited sketch, of the absolute self-consciousness of God accommodated to the capacities of the human or creaturely consciousness. But however great the distance is, the source (principium essendi) of our knowledge of God is solely God himself, the God who reveals himself freely, self-consciously, and genuinely.
