172 And so, dear brothers, with the ardent wish that peace may come upon the flocks committed to your care, for the special benefit of those who are most lowly and in the greatest need of help and defense, lovingly in the Lord We bestow on you, on Our priests both secular and regular, on religious both men and women, on all the faithful and especially those who give wholehearted obedience to these Our exhortations, Our Apostolic Blessing. And upon all men of good will, to whom We also address this encyclical, We implore from God health and prosperity.
