"Humility is the safeguard of chastity. In the matter of purity, there is no greater danger than not fearing the danger. For my part, when I find a man secure of himself and without fear, I give him up for lost. I am less alarmed for one who is tempted and who resists by avoiding the occasions, than for one who is not tempted and is not careful to avoid occasions. When a person puts himself in an occasion, saying, I shall not fall, it is an almost infallible sign that he will fall, and with great injury to his soul."
