Apostolic Exhortation Catechesi tradendae (extract)
46. From the oral teaching by the Apostles and the letters circulating among the Churches down to the most modern means, catechesis has not ceased to look for the most suitable ways and means for its mission, with the active participation of the communities and at the urging of the pastors. This effort must continue.
I think immediately of the great possibilities offered by the means of social communication and the means of group communication: television, radio, the press, records, tape-recordings -- the whole series of audio-visual means. The achievements in these spheres are such as to encourage the greatest hope. Experience shows, for example, the effect had by instruction given on radio or television, when it combines a high aesthetic level and rigorous fidelity to the Magisterium. The Church now has many opportunities for considering these questions--as, for instance, on Social Communications Days--and it is not necessary to speak of them at length here, in spite of their prime importance.
