A few quotes to get an idea:
"All priests have as their primary duty the proclamation of Jesus Christ, the incarnate Word of God, and the communication of His saving grace in the Sacraments. ... Responding adequately to this challenge amid today's cultural shifts, to which young people are especially sensitive, necessarily involves using new communications technologies. ... Priests stand at the threshold of a new era: as new technologies create deeper forms of relationship across greater distances, they are called to respond pastorally by putting the media ever more effectively at the service of the Word."
"Using new communication technologies, priests ... must learn, from the time of their formation, how to use these technologies in a competent and appropriate way, shaped by sound theological insights and reflecting a strong priestly spirituality grounded in constant dialogue with the Lord. Yet priests present in the world of digital communications should be less notable for their media savvy than for their priestly heart, their closeness to Christ. This will not only enliven their pastoral outreach, but also will give a 'soul' to the fabric of communications that makes up the 'Web'."
"Our pastoral presence in that world must thus serve to show our contemporaries, especially the many people in our day who experience uncertainty and confusion, 'that God is near; that in Christ we all belong to one another'. Who better than a priest, as a man of God, can develop and put into practice, by his competence in current digital technology, a pastoral outreach capable of making God concretely present in today's world?"
"The development of the new technologies and the larger digital world represents a great resource for humanity as a whole. ... But this development likewise represents a great opportunity for believers. No door can or should be closed to those who, in the name of the risen Christ, are committed to drawing near to others. To priests in particular the new media offer ever new and far-reaching pastoral possibilities, encouraging them to embody the universality of the Church's mission, to build a vast and real fellowship, and to testify in today's world to the new life which comes from hearing the Gospel of Jesus."
As I have read on a number of other blogs, perhaps the Holy Father is saying, "Go forth and blog." :)
