As faith deepens, and as communion deepens with it, it becomes more and more intensive and at the same time reaches out to affect everything else we think and do. I do not mean merely that now all our thoughts are couched in certain fideist or pietistic formulas, but rather that faith gives a dimension of simplicity and depth to all our apprehensions and to all our experiences.
What is this dimension of depth? It is the incorporation of the unknown and of the unconscious into our daily life. Faith brings together the known and the unknown so that they overlap: or rather, so that we are aware of their overlapping. Actually, our whole life is a mystery of which very little comes to our conscious understanding. But when we accept only what we can consciously rationalize, our life is actually reduced to the most pitiful limitations, though we may think quite otherwise.
