"Filthy talk makes us feel comfortable with filthy action. But the one who knows how to control the tongue is prepared to resist the attacks of lust."
-St. Clement of Alexandria
"Never talk of impure things or events, not even to deplore them. Look, it's a subject that sticks more than tar. Change the conversation, or if that's not possible, continue, but speaking of the need and beauty of holy purity--a virtue of the men who know what their souls are worth."
-St. Josemaria Escriva
The man of impure speech is a "person whose lips are but an opening and a supply pipe which hell uses to vomit its impurities upon the earth."
-St. John Vianney
"That conversation . . . was as dirty as a sewer! It is not enough for you to take no part in it. You must show your repugnance to it strongly!"
-St. Josemaria Escriva
"I have never talked about impurity. . . . But I have spoken many times, as I have to do, about chastity, purity, and the joyful affirmation of love."
-St. Josemaria Escriva
