"Every understanding that touches upon God must have a certain fragility and transparence; it cannot be something fixed once and for all, but must itself urge us to call this understanding into question and stimulate us to seek one further along in the same direction. If such an understanding does remain fixed in our mind, we place limits on God corresponding to the boundaries of this particular understanding. We may even forget God entirely and find that our whole attention is concentrated on this particular understanding or upon the words which express God. In such a case our 'understanding' becomes an 'idol,' a false god. The understanding or the word we use must always make God transparent, as one who is not contained within it, as one who transcends all understanding and reveals himself now under one aspect of his infinite richness and now under another..."
