The Catholic of a living faith, and he alone, can make this investigation. Our investigation goes only so deep as our love goes. An attitude of mere neutrality, or a cold realism is of no use here. Or, rather, only the man who himself lives in the Catholic life-stream, who in his own life daily feels the forces which pulsate through the vast body of Catholicism and which make it what it is: only he can know the full meaning and complete reality of it. Just as the loving child alone can truly know the character of its beloved mother, and just as the deepest elements of that character, the tenderness and intimacies of her maternal love, cannot be demonstrated by argument but only learnt by experience, just so only the believing and loving Catholic can see into the heart of Catholicism, and feeling, living, experiencing, discover with that “esprit de finesse” of which Pascal speaks, that is with the comprehensive intuition of his innermost soul, the secret forces and fundamental motive powers of its being.** And so an investigation into the nature of Catholicism inevitably becomes a confession of faith, an expression of the Catholic consciousness.** It is nothing else, and seeks to be nothing else, than the simple analysis of this consciousness, and becomes of itself an analysis of the Church’s self-consciousness. It is the answer to the question: How does the Catholic experience his Church, how does it work on him, where lie for him the creative forces of Catholicism, the intimate center of its creative being?
