102 We also address Ourselves with a father's love to the members of the diocesan and religious clergy: those who are your close assistants in your Curia, Venerable Brethren; those who toil in seminaries at a very important work, the formation and education of youths called to the Lord's service; those, finally, who are parish priests in crowded cities, in towns, or in distant and lonely outposts and whose mission today is very difficult, very demanding, and of the utmost importance.
