Families need to take a firm stance in safeguarding the threshold of their homes, in defending the dignity of each person. Guard your families against pornography, which nowadays under various forms affects people's minds, especially those of children and young people. Defend the purity of morals in your homes and in society. ... The purer families are, the healthier the nation will be." - POPE JOHN PAUL II, Sandomierz, Poland, June 12, 1999
