19. There should be nothing about your behavior to attract attention. Besides, you should not seek to please by your apparel, but by a good life.
20. Whenever you go out, walk together, and when you reach your destination, stay together.
21. In your walking, standing, and every movement, let nothing occur to give offense to anyone who sees you, but only what becomes your holy state of life.
22. Although your eyes may chance to rest upon persons of the other sex, you must not fix your gaze on them. Seeing them when you go out is not forbidden, but it is sinful to desire them or to wish them to desire you, for it is not by touch or passionate feeling alone but by one’s gaze as well that lustful desires mutually arise. And do not say that your hearts are pure if there is immodesty of the eye, because the unchaste eye carries the message of an impure heart. And when such hearts disclose their unchaste desires in a mutual gaze, even without saying a word, then it is that chastity itself suddenly goes out of their life, even though their bodies remain unsullied by unchaste acts.
23. And whoever fix their gaze upon a person of the other sex and like to have that person’s gaze fixed upon them, must not suppose that others do not see what they are doing. They are very much seen, even by those they think do not see them. But suppose that all this escapes the notice of human beings -- what will they do about God who sees from on high and from whom nothing is hidden? Or are you to imagine that he does not see because he sees with a patience as great as his wisdom? Let religious, then, have such fear of God that they will not want to be an occasion of sinful pleasure to those of the other sex. Ever mindful that God sees all things, let them not desire to look at such persons lustfully. For it is on this point that fear of the Lord is recommended, where it is written: An abomination to the Lord is he who fixes his gaze (Proverbs 27:20).
24. So when you are together in church and anywhere else where persons of the other sex are present, exercise a mutual care over purity of life. Thus, by mutual vigilance over one another will God, who dwells in you, grant you his protection.
25. If you notice in any of your brothers or sisters this wantonness of the eye, of which I am speaking, admonish them at once so that the beginning of evil will not grow more serious, but will be promptly corrected.
26. But if you see them doing the same thing again on some other day, even after admonition, then whoever had occasion to discover this must report them as they would a wounded person in need of treatment. But let the offense first be pointed out to two or three so that the persons can be proven guilty on the testimony of these two or three and be punished with due severity. And do not charge yourselves with ill-will when you bring this offense to light. Indeed, yours is the greater blame if you allow your brothers or sisters to be lost through your silence when you are able to bring about their correction by your disclosure. If your brothers or sisters, for example, were suffering a bodily wound that they wanted to hide for fear of undergoing treatment, would it not be cruel of you to remain silent and a mercy on your part to make this known? How much greater then is your obligation to make their condition known lest they continue to suffer a more deadly wound of the soul.
27. But if they fail to correct the fault despite this admonition, they should first be brought to the attention of the superior before the offense is made known to the others who will have to prove their guilt, in the event that they deny the charge. Thus, corrected in private, their fault can perhaps be kept from the others. But should they feign ignorance, the others are to be summoned so that in the presence of all they can be proven guilty, rather than stand accused on the word of one alone. Once proven guilty, they must undergo salutary punishment according to the judgment of the superior or priest having the proper authority. If they refuse to submit to punishment, they shall be expelled from your brotherhood or sisterhood even if they do not withdraw of their own accord. For this too is not done out of cruelty, but from a sense of compassion, so that many others may not be lost through their bad example.
28. And let everything I have said about not fixing one’s gaze be also observed carefully and faithfully with regard to other offenses: to find them out, to ward them off, to make them known, to prove and punish them -- all out of love for our fellows and a hatred of sin.
29. But if any should go so far in wrongdoing as to receive letters in secret from a person of the other sex, or small gifts of any kind, you ought to show mercy and pray for them if they confess this of their own accord. But if the offense is detected and they are found guilty, they must be more severely chastised according to the judgment of the priest or superior.
