3. This document is concerned with concrete cooperation and does not deal directly with questions about doctrinal dialogue in communications programs or productions. It can be said, on the other hand, that the Catholic doctrinal and moral teaching is an irreplaceable reference point for Catholic communicators. It is the responsibility of the competent ecclesiastical authorities - on the different levels: local, national, continental and world - to safeguard the doctrinal and moral aspect of every communications activity. The responsible pastoral officials have the right and the duty to give their judgment and their specific directions in this regard. They will evaluate in each case the risks and the opportuneness of common initiatives, keeping in mind the necessity to safeguard the specific identity of Catholic initiatives.
