Sollicitudo Rei Socialis: On Social Concern
36 It is important to note therefore that a world which is divided into blocs, sustained by rigid ideologies, and in which instead of interdependence and solidarity different forms of imperialism hold sway, can only be a world subject to structures of sin. The sum total of the negative factors working against a true awareness of the universal common good, and the need to further it, gives the impression of creating, in persons and institutions, an obstacle which is difficult to overcome. If the present situation can be attributed to difficulties of various kinds, it is not out of place to speak of "structures of sin," which, as I stated in my Apostolic Exhortation Reconciliatio et Paenitentia , are rooted in personal sin, and thus always linked to the concrete acts of individuals who introduce these structures, consolidate them and make them difficult to remove. And thus they grow stronger, spread, and become the source of other sins, and so influence people's behavior. "Sin" and "structures of sin" are categories which are seldom applied to the situation of the contemporary world. However, one cannot easily gain a profound understanding of the reality that confronts us unless we give a name to the root of the evils which afflict us. One can certainly speak of "selfishness" and of "shortsightedness," of "mistaken political calculations" and "imprudent economic decisions." And in each of these evaluations one hears an echo of an ethical and moral nature. Man's condition is such that a more profound analysis of individuals' actions and omissions cannot be achieved without implying, in one way or another, judgments or references of an ethical nature. This evaluation is in itself positive, especially if it is completely consistent and if it is based on faith in God and on his law, which commands what is good and forbids evil. In this consists the difference between sociopolitical analysis and formal reference to "sin" and the "structures of sin." According to this latter viewpoint, there enter in the will of the Triune God, his plan for humanity, his justice and his mercy. The God who is rich in mercy, the Redeemer of man, the Lord and giver of life, requires from people clear cut attitudes which express themselves also in actions or omissions toward one's neighbor. We have here a reference to the "second tablet" of the Ten Commandments (cf. Ex 20:12-17; Dt 5:16-21). Not to observe these is to offend God and hurt one's neighbor, and to introduce into the world influences and obstacles which go far beyond the actions and brief life span of an individual. This also involves interference in the process of the development of peoples, the delay or slowness of which must be judged also in this light.
