Catholic social teaching pays attention to the necessity of showing greater interest in theprocess of evangelization by means of social communications, especialy through new mediaplatforms. These platforms promote and impose their own lifestyles, behaviors, preferences, choices,hierarchies of values and motivations. The presence of the Church on these platforms leads toa greater awareness of what Christianity is. With an increased involvement of the Church inthe media, there will be a greater space given in conversations about such themes as Church, God,faith, conscience and responsibility. Mass media puts pastoral ministry in a new perspective, but italso constitutes a real challenge, especially in so far as ethical requirements are concerned.
