18 And since we are seeking the advantage of continency, let us also avoid everything that is pernicious and hostile to it. And I will not pass over those things, which while by negligence they come into use, have made for themselves a usurped licence, contrary to modest and sober manners. Some are not ashamed to be present at marriage parties, and in that freedom of lascivious discourse to mingle in unchaste conversation, to hear what is not becoming, to say what is not lawful, to expose themselves, to be present in the midst of disgraceful words and drunken banquets, by which the ardour of lust is kindled, and the bride is animated to bear, and the bridegroom to dare lewdness. What place is there at weddings for her whose mind is not towards marriage? Or what can there be pleasant or joyous in those engagements for her, where both desires and wishes are different from her own? What is learned there— what is seen? How greatly a virgin falls short of her resolution, when she who had come there modest goes away immodest! Although she may remain a virgin in body and mind, yet in eyes, in ears, in tongue, she has diminished the virtues that she possessed.
