It is mutual respect which makes friendship lasting.

Knowledge is one thing, virtue is another.

Go down again - I dwell among the people.

Good is never accomplished except at the cost of those who do it, truth never breaks through except through the sacrifice of those who spread it.

We should ever conduct ourselves towards our enemy as if he were one day to be our friend.

God has created all things for good; all things for their greatest good; everything for its own good. What is the good of one is not the good of another; what makes one man happy would make another unhappy. God has determined, unless I interfere with His plan, that I should reach that which will be my greatest happiness. He looks on me individually, He calls me by my name, He knows what I can do, what I can best be, what is my greatest happiness, and He means to give it me.

Without self-knowledge you have no root in yourselves personally; you may endure for a time, but under affliction or persecution your faith will not last. This is why many in this age (and in every age) become infidels, heretics, schismatics, disloyal despisers of the Church. They cast off the form of truth, because it never has been to them more than a form. They endure not, because they never have tasted that the Lord is gracious; and they never have had experience of His power and love, because they have never known their own weakness and need.
