24 As for the rest, this sacred Synod is confident that its issuance of these instructions and norms will be gladly accepted and religiously kept by all the Church's children. By using these helps they will experience no harm and, like salt and light, they will give savor to the earth and brighten the world. Moreover, the Synod invites all men of good will, especially those who have charge of these media, to strive to turn them solely to the good of society, whose fate depends more and more on their proper use. Thus, as was the case with ancient works of art, the name of the Lord may be glorified by these new discoveries in accordance with those words of the Apostle: "Jesus Christ, yesterday and today, and the same forever."
