“The Church sees these media as ‘gifts of God' which, in accordance with his providential design, unite men in brotherhood and so help them to cooperate with his plan for their salvation”

"As the Church understands it, the history of human communication is something like a long journey, bringing humanity “from the pride-driven project of Babel and the collapse into confusion and mutual incomprehension to which it gave rise (cf. Gen 11:1-9), to Pentecost and the gift of tongues: a restoration of communication, centered on Jesus, through the action of the Holy Spirit”.⁶ In the life, death, and resurrection of Christ, “communication among men found its highest ideal and supreme example in God who had become man and brother”.⁷

The modern media of social communication are cultural factors that play a role in this story. As the Second Vatican Council remarks, “although we must be careful to distinguish earthly progress clearly from the increase of the kingdom of Christ”, nevertheless “such progress is of vital concern to the kingdom of God, insofar as it can contribute to the better ordering of human society”.⁸ Considering the media of social communication in this light, we see that they “contribute greatly to the enlargement and enrichment of men's minds and to the propagation and consolidation of the kingdom of God”.⁹

Today this applies in a special way to the Internet, which is helping bring about revolutionary changes in commerce, education, politics, journalism, the relationship of nation to nation and culture to culture—changes not just in how people communicate but in how they understand their lives."
