All men know how much harm is done by bad films; they sing the praises of lust and desire, and at the same time provide occasions of sin; they seduce the young from the right path; they present life in a false light; they obscure and weaken the wise counsels of attaining perfection; they destroy pure love, the sanctity of matrimony and the intimate needs of family life. They seek moreover to inculcate prejudiced and false opinions among individuals, classes of society and the different nations and peoples. (Papal Encyclical, Vigilanti Cura, 29 June 1936).
