Modern methods of communication can be of great benefit, and of great harm when misused. This is nothing new.
The Church recognizes that these media, if properly utilized, can be of great service to (humankind), since they greatly contribute to (human) entertainment and instruction as well as to the spread and support of the Kingdom of God. The Church recognizes, too, that (people) 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. Hence, this sacred Synod, attentive to the watchful concern manifested by the Supreme Pontiffs and Bishops in a matter of such great importance, judges it to be its duty to treat of the principal questions linked with the media of social communication. It trusts, moreover, that the teaching and regulations it thus sets forth will serve to promote, not only the eternal welfare of Christians, but also the progress of all (humankind).
As with many other documents, the Church has hope on two fronts here. First, that the welfare of believers will benefit. Second, the Council is always solicitous of possible benefits for the whole human culture.
