15 Young widows, of whom some “are already turned aside after Satan, when they have begun to wax wanton against Christ” and wish to marry, generally make such excuses as these. “My little patrimony is daily decreasing, the property which I have inherited is being squandered, a servant has spoken insultingly to me, a maid has neglected my orders. Who will appear for me before the authorities? Who will be responsible for the rents of my estates? Who will see to the education of my children, and to the bringing up of my slaves?” Thus, shameful to say, they put that forward as a reason for marrying again, which alone should deter them from doing so. For by marrying again a mother places over her sons not a guardian but a foe, not a father but a tyrant. Inflamed by her passions she forgets the fruit of her womb, and among the children who know nothing of their sad fate the lately weeping widow dresses herself once more as a bride. Why these excuses about your property and the insolence of slaves? Confess the shameful truth. No woman marries to avoid cohabiting with a husband. At least, if passion is not your motive, it is mere madness to play the harlot just to increase wealth. You do but purchase a paltry and passing gain at the price of a grace which is precious and eternal! If you have children already, why do you want to marry? If you have none, why do you not fear a recurrence of your former sterility? Why do you put an uncertain gain before a certain loss of self-respect?
A marriage-settlement is made in your favour today but in a short time you will be constrained to make your will. Your husband will feign sickness and will do for you what he wants you to do for him. Yet he is sure to live and you are sure to die. Or if it happens that you have sons by the second husband, domestic strife is certain to result and intestine disputes. You will not be allowed to love your first children, nor to look kindly on those to whom you have yourself given birth. You will have to give them their food secretly; yet even so your present husband will bear a grudge against your previous one and, unless you hate your sons, he will think that you still love their father. But your husband may have issue by a former wife. If so when he takes you to his home, though you should be the kindest person in the world, all the commonplaces of rhetoricians and declamations of comic poets and writers of mimes will be hurled at you as a cruel stepmother. If your stepson fall sick or have a headache you will be calumniated as a poisoner. If you refuse him food, you will be cruel, while if you give it, you will be held to have bewitched him. I ask you what benefit has a second marriage to confer great enough to compensate for these evils?
