Saint Ambrose of Milan

To avoid dissensions we should be ever on our guard, more especially with those who drive us to argue with them, with those who vex and irritate us, and who say things likely to excite us to anger. When we find ourselves in company with quarrelsome, eccentric individuals, people who openly and unblushingly say the most shocking things, difficult to put up with, we should take refuge in silence, and the wisest plan is not to reply to people whose behavior is so preposterous. Those who insult us and treat us contumeliously are anxious for a spiteful and sarcastic reply: the silence we then affect disheartens them, and they cannot avoid showing their vexation; they do all they can to provoke us and to elicit a reply, but the best way to baffle them is to say nothing, refuse to argue with them, and to leave them to chew the cud of their hasty anger. This method of bringing down their pride disarms them, and shows them plainly that we slight and despise them. 

-- Saint Ambrose of Milan

Saint Agnes of Rome

Christ made my soul beautiful with the jewels of grace and virtue. I belong to Him whom the angels serve. 

-- Saint Agnes of Rome

Saint Augustine of Hippo

I will suggest a means whereby you can praise God all day long, if you wish. Whatever you do, do it well, and you have praised God. 

-- Saint Augustine of Hippo

Saint Mary Magdalene de Pazzi

Come, Holy Spirit. Spirit of truth, you are the reward of the saints, the comforter of souls, light in the  darkness, riches to the poor, treasure to lovers, food for the hungry, comfort to those who are wandering; to sum up, you are the one in whom all treasures are contained. 

-- Saint Mary Magdalene de Pazzi

Saint Jaime Hilario Barbal

God be blessed; I’ll pray for all of you in heaven. What more could I desire than to die for no other crime but that of being a religious and for having made my contribution to the Christian education of children. Dear father and family, I have been judged and condemned to death. I accept the sentence with joy. No charges have been brought against me. I have been condemned to death only because I am a religious. Do not weep for me, I am not worthy of pity. I shall die for God and for my country. Farewell, I shall be waiting for you in heaven. 

-- Saint Jaime Hilario Barbal writing to his family after learning of his death sentence

Saint John Bosco

No matter how good food is, if poison is mixed with it, it may cause the death of him who eats it. So it is with conversation. A single bad word, an evil action, an unbecoming joke, is often enough to harm one or more young listeners, and may later cause them to lose God's grace.

-- Saint John Bosco

Saint Teresa of Avila

We always find that those who walked closest to Christ were those who had to bear the greatest trials.

-- Saint Teresa of Avila
