[R]est assured that, when you remain thus in the state in which obedience has placed you, the merit of this same obedience extends over everything you do, giving each action inestimable value, even when things do not turn out as you wish.

Quotes from the same author

I am determined, even if they throw mud in my face, never to show any resentment, nor break with them, nor deviate from the esteem and honor I owe them in the sight of God. If they forget themselves and say or do something offensive against your little bark, even if it is done purposely to make it sink, bear with it for the love of God, who will save you from shipwreck and calm the storm. Do not complain or even say a single work about it. In spite of everything, continue to compliment them when you meet, as if nothing were amiss.
 Vincent de Paul
I see that you are not sure of what you should do. You must remain steadfast, Monsieur. It would be a great wrong for you to leave and an irreparable scandal to the town and the Company. If you were to abandon the house, I do not think people would ever be willing to welcome us back. Fear not; calm will follow the storm, and perhaps soon.
 Vincent de Paul
In the name of God, Monsieur, let us not be so little attached to God's service that we yield to a useless fear which may cause us to abandon the task He has given us.
 Vincent de Paul
An honorable man would never abandon his friend in time of need, especially if they were in a foreign country. Why? For fear of acting like a coward or of being boorish. I repeat, I admire the fact that, those persons have, through human respect, more courage than Christians and priests have, through charity or through their good intentions.
 Vincent de Paul
Far from rejecting such a good man as you, He never even abandons a wicked man who hopes for His mercy.
 Vincent de Paul
