Archbishop Joseph F. Naumann of Kansas City, KS has initiated an important program aimed at fostering the virtue of chastity and building awareness of the evil effects of pornography, including suggesting ways Catholics can protect their families from its influence and counseling persons caught in this sin. [Although, the best help I personally can think of is to make a good confession that will supply God's grace to avoid the near occasions of sins.]
Every parish was required to show a movie of the Archbishop announcing As for Me and My House at all weekend Masses. As people left the churches they were handed material to take home, including a good checklist for a spiritually healthy family. The Archbishop's newspaper, The Leaven, also provided an important article on pornography. [I can vouch for the problem of pornography within the workplace--several years ago we had to discharge a good employee. He was warned, but continued his pornographic viewing anyway.]
What is missing from As for Me and My House? I don't see a recommendation that parents install and use filters on their internet and cable service. One internet filter that can be highly recommended is found here. Other filters are described and rated here.
