Evangelii Nuntiandi §42

42. Secondly, it is not superfluous to emphasize the importance and necessity of preaching. "And how are they to believe in him of whom they have never heard? And how are they to hear without a preacher?... So faith comes from what is heard and what is heard comes by the preaching of Christ."[69] This law once laid down by the Apostle Paul maintains its full force today.

Preaching, the verbal proclamation of a message, is indeed always indispensable. We are well aware that modern man is sated by talk; he is obviously often tired of listening and, what is worse, impervious to words. We are also aware that many psychologists and sociologists express the view that modern man has passed beyond the civilization of the word, which is now ineffective and useless, and that today he lives in the civilization of the image. These facts should certainly impel us to employ, for the purpose of transmitting the Gospel message, the modern means which this civilization has produced. Very positive efforts have in fact already been made in this sphere. We cannot but praise them and encourage their further development. The fatigue produced these days by so much empty talk and the relevance of many other forms of communication must not however diminish the permanent power of the word, or cause a loss of confidence in it. The word remains ever relevant, especially when it is the bearer of the power of God.[70] This is why St. Paul's axiom, "Faith comes from what is heard,"[71] also retains its relevance: it is the Word that is heard which leads to belief.
