The Archdiocese of St. Louis has begun an initiative for anti-pornography: As for Me and My House. This parish based initiative is aimed at fostering the virtue of chastity by building awareness of the effects of pornography in society, offering support and healing for those harmed by it, and educating Catholics on what they can do to protect their families from its influence.
 

What is pornography?
According to Catholic Catechism:
“Pornography consists in removing real or simulated sexual acts from the intimacy of the partners,  in order to display them deliberately to third parties.  It offends against chastity because it perverts the conjugal act,  the intimate giving of spouses to each other. It does grave injury to the dignity of its participants  (actors, vendors, the public), since each one becomes an object of base pleasure and illicit profit for others. It immerses all who are involved in the illusion of a fantasy world. It is a grave offense. Civil authorities should prevent the production and distribution of pornographic materials” (CCC, 2354).
