He ought to have a sound knowledge of all questions which confront the souls of Christians with regard to Motion Pictures, Radio and Television. As We said in a discourse to those taking part in a Study Week for the bringing up to date of pastoral practice in Italy at the present time, "The priest with `the care of souls' can and must know what modern science, art and technique assert whenever they touch on the end of man and his moral and religious life".56 Let him learn to use these aids correctly as often as, in the prudent judgment of ecclesiastical authority, the nature of the ministry entrusted to him and the need of assisting an increasing number of souls demand it. Finally, if these arts are employed by the priest to advantage, his prudence, self-control and sense of responsibility will shine out as an example to all Christians.
