"Suppose, for example, a woman burns with love for a certain man and desires to be taken as his wife. Will she not do everything and rule all her emotions in such a way that she may learn how to please the one she affectionately loves, lest perhaps if she acts in anything against his will, that excellent man might refuse her as his wife and scorn her? Could that woman, who burns with her love of that man with all her heart, all her soul, and all her strength, commit either adultery when she knew he loved chastity, or murder when she knew he was gentle, or theft when she knew that generosity pleased him or desire anything else when she had all her desires bound up with her love of that man? This, then, is how in the perfection of loving affection every commandment is said to be summed up and the meaning of the Law and the prophets to depend upon it."
