Sollicitudo Rei Socialis §6

⁶ We should see something more in this than simple chronological proximity. The Encyclical Populorum Progressio presents itself, in a certain way, as a document which applies the teachings of the Council. It not only makes continual reference to the texts of the Council, but it also flows from the same concern of the Church which inspired the whole effort of the Council-and in a particular way the Pastoral Constitution Gaudium et Spes - to coordinate and develop a number of themes of her social teaching. We can therefore affirm that the Encyclical Populorum Progressio is a kind of response to the Council's appeal with which the Constitution Gaudium et Spes begins: "The joys and the hopes. the griefs and the anxieties of the people of this age, especially those who are poor or in any way afflicted, these too are the joys and hopes, the griefs and anxieties of the followers of Christ. Indeed, nothing genuinely human fails to raise an echo in their hearts." These words express the fundamental motive inspiring the great document of the Council, which begins by noting the situation of poverty and of underdevelopment in which millions of human beings live. This poverty and underdevelopment are, under another name, the "griefs and the anxieties" of today, of "especially those who are poor." Before this vast panorama of pain and suffering, the Council wished to suggest horizons of joy and hope. The Encyclical of Paul VI has the same purpose, in full fidelity to the inspiration of the Council.
