Faith is illuminative, not operative; it does not force obedience, though it increases responsibility; it heightens guilt, but it does not prevent sin. The will is the source of action.

Thought and speech are inseparable from each other. Matter and expression are parts of one; style is a thinking out into language.

How can we feel our need of His help, or our dependence on Him, or our debt to Him, or the nature of His gift to us, unless we know ourselves.... This is why many in this age (and in every age) become infidels, heretics, schismatics, disloyal despisers of the Church.... They have never had experience of His power and love, because they have never known their own weakness and need.

God has created me to do Him some definite service; He has committed some work to me which he has not committed to another, I have my mission ... He has not created me for naught ... If I am in sickness, my sickness may serve Him; If I am in sorrow, my sorrow may serve Him. He does nothing in vain. He knows what He is about.

Man is emphatically self-made.
