Magnifica Humanitas §36

³⁶ In Octogesima Adveniens , written on the occasion of the eightieth anniversary of Rerum Novarum , Paul VI applied this perspective to postindustrial society, marked by urbanization, new forms of poverty and rapid cultural changes that called into question the future of individuals and communities. Paul VI believed that although the Gospel was proclaimed, written and lived out in a historical and cultural context very different from our own, its message was not “outdated.” Instead, it offers a vision of the human person, relationships, authority and the common good that is still capable of guiding economic, political and cultural choices today. In other words, the Gospel remains relevant because it provides the criteria for recognizing what humanizes or dehumanizes and what liberates or oppresses in ever-changing situations. For the Social Doctrine of the Church, Paul VI ’s most demanding legacy is precisely this: as long as there are people in the world who are excluded from the development befitting human dignity, the Christian community cannot be content with a theoretical proclamation of peace. Rather, beginning where people are marginalized, it must allow the Gospel to pass judgment on those economic and political structures which — as John Paul II would later remind us — can become veritable “structures of sin.” As a result, no person or people will be treated as expendable in the processes of development.
