God As Mystery
“Unless we start out with a feeling of awe and astonishment- with what is often called a sense of the numinous- we shall make little progress on the Way… The Greek Fathers liken man’s encounter with God to the experience of someone walking over the mountains in the mist: he takes a step forward and suddenly finds that he is on the edge of a precipice, with no solid ground beneath his foot but only a bottomless abyss.
Or else they use the example of a man standing at night in a darkened room: he opens the shutter over a window, and as he looks out there is a sudden flash of lightning, causing him to stagger backwards, momentarily blinded. Such is the effect of coming face to face with the living mystery of God: we are assailed by dizziness; all the familiar footholds vanish, and there seems nothing for us to grasp; our inward eyes are blinded, our normal assumptions shattered.”
