"Among the wonderful technological discoveries which men of talent, especially in the present era, have made with God's help, the Church welcomes and promotes with special interest those which have a most direct relation to men's minds and which have uncovered new avenues of communicating most readily news, views and teachings of every sort. The most important of these inventions are those media which, such as the press, movies, radio, television and the like, can, of their very nature, reach and influence, not only individuals, but the very masses and the whole of human society, and thus can rightly be called the media of social communication.
The Church recognizes that these media, if properly utilized, can be of great service to mankind, since they greatly contribute to men's entertainment and instruction as well as to the spread and support of the Kingdom of God. The Church recognizes, too, that men can employ these media contrary to the plan of the Creator and to their own loss. Indeed, the Church experiences maternal grief at the harm all too often done to society by their evil use.
