2 In the Organic Development of the Church's Social Action It is certainly true that work, as a human issue, is at the very centre of the "social question" to which, for almost a hundred years, since the publication of the above-mentioned Encyclical, the Church's teaching and the many undertakings connected with her apostolic mission have been especially directed. The present reflections on work are not intended to follow a different line, but rather to be in organic connection with the whole tradition of this teaching and activity. At the same time, however, I am making them, according to the indication in the Gospel, in order to bring out from the heritage of the Gospel "what is new and what is old" . Certainly, work is part of "what is old"- as old as man and his life on earth. Nevertheless, the general situation of man in the modern world, studied and analyzed in its various aspects of geography, culture and civilization, calls for the discovery of the new meanings of human work. It likewise calls for the formulation of the new tasks that in this sector face each individual, the family, each country, the whole human race, and, finally, the Church herself. During the years that separate us from the publication of the Encyclical Rerum Novarum, the social question has not ceased to engage the Church's attention. Evidence of this are the many documents of the Magisterium issued by the Popes and by the Second Vatican Council, pronouncements by individual Episcopates, and the activity of the various centres of thought and of practical apostolic initiatives, both on the international level and at the level of the local Churches. It is difficult to list here in detail all the manifestations of the commitment of the Church and of Christians in the social question, for they are too numerous. As a result of the Council, the main coordinating centre in this field is the Pontifical Commission Justice and Peace, which has corresponding bodies within the individual Bishops' Conferences. The name of this institution is very significant. It indicates that the social question must be dealt with in its whole complex dimension. Commitment to justice must be closely linked with commitment to peace in the modern world. This twofold commitment is certainly supported by the painful experience of the two great world wars which in the course of the last ninety years have convulsed many European countries and, at least partially, countries in other continents. It is supported, especially since the Second World War, by the permanent threat of a nuclear war and the prospect of the terrible self-destruction that emerges from it. If we follow the main line of development of the documents of the supreme Magisterium of the Church, we find in them an explicit confirmation of precisely such a statement of the question. The key position, as regards the question of world peace, is that of John XXIII's Encyclical Pacem in Terris. However, if one studies the development of the question of social justice, one cannot fail to note that, whereas during the period between Rerum Novarum and Pius XI's Quadragesimo Anno the Church's teaching concentrates mainly on the just solution of the "labour question" within individual nations, in the next period the Church's teaching widens its horizon to take in the whole world. The disproportionate distribution of wealth and poverty and the existence of some countries and continents that are developed and of others that are not call for a levelling out and for a search for ways to ensure just development for all. This is the direction of the teaching in John XXIII's Encyclical Mater et Magistra, in the Pastoral Constitution Gaudium et Spes of the Second Vatican Council, and in Paul VI's Encyclical Populorum Progressio. This trend of development of the Church's teaching and commitment in the social question exactly corresponds to the objective recognition of the state of affairs. While in the past the "class" question was especially highlighted as the centre of this issue, in more recent times it is the "world" question that is emphasized. Thus, not only the sphere of class is taken into consideration but also the world sphere of inequality and injustice, and as a consequence, not only the class dimension but also the world dimension of the tasks involved in the path towards the achievement of justice in the modern world. A complete analysis of the situation of the world today shows in an even deeper and fuller way the meaning of the previous analysis of social injustices; and it is the meaning that must be given today to efforts to build justice on earth, not concealing thereby unjust structures but demanding that they be examined and transformed on a more universal scale.
