"Gibney was not what you would call pious. In fact, he had an attitude that would be commonly called impious, only I believe God understood well enough that his violence and sarcasms covered a sense of deep metaphysical dismay--an anguish that was real, though not humble enough to be of much use to his soul. What was materially impiety in him was directed more against common ideas and notions which he saw or considered to be totally inadequate, and maybe it subjectively represented a kind of oblique zeal for the purity of God, this rebellion against the commonplace and trite, against mediocrity, religiosity."
~Merton, The Seven Storey Mountain, pp. 200-201
