A mortal sin of scandal committed by women that go with them shamelessly exposed breast, or that expose their members incorrectly. Also by the actors in lewd comedies , and more par people who make up these comedies ; also by painters who paint obscene images or like, and by the heads of families who keep these photos in their homes . The father who speaks obscene or blasphemous saints in the presence of her children, and the mother who brings in her home to live among his girls young men who are in love with them Or fiancées or other suspects, are guilty of a more serious sin of scandal. Some mothers say, “I do not think any harm.” I reply that it is their duty to suspect; otherwise they shall give account to God for all the sins that can follow.
