To the Bishops, Priests Religious Families, sons and daughters of the Church and all people of good will for the twentieth anniversary of "Populorum Progressio" 1987.12.30
Venerable Brothers and dear Sons and Daughters, Health and the Apostolic Blessing!
1. The social concern of the Church, directed towards an authentic development of man and society which would respect and promote all the dimensions of the human person, has always expressed itself in the most varied ways. In recent years, one of the special means of intervention has been the Magisterium of the Roman Pontiffs which, beginning with the Encyclical Rerum Novarum of Leo XIII as a point of reference,1 has frequently dealt with the question and has sometimes made the dates of publication of the various social documents coincide with the anniversaries of that first document.2
