Encyclical Letter *Populorum Progressio*, n. 54: *loc. cit*., pp. 283f.: "Developing countries will thus no longer risk being overwhelmed by debts whose repayment swallows up the greater part of their gains. Rates of interest and time for repayment of the loan could be so arranged as not to be too great a burden on either party, taking into account free gifts, interest-free or low-interest loans, and the time needed for liquidating the debts." **[40](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-14)**. Cf.

Cf. Second Vatican Ecumenical Council, Pastoral Constitution on the Church in the Modern World, *Gaudium et Spes*, n. 78; Paul VI, Encyclical Letter *Populorum Progressio*, n. 76: *loc. cit.*, pp. 294f.: "To wage war on misery and to struggle against injustice is to promote, along with improved conditions, the human and spiritual progress of all men, and therefore the common good of humanity...peace is something that is built up day after day, in the pursuit of an order intended by God, which implies a more perfect form of justice among men." **[49](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1D)**. Cf. Apostolic Exhortation *Familiarls Consortio* (November 22, 1981), n. 6: *AAS* 74 (1982), p. 88: "...history is not simply a fixed progression toward what is better, but rather an event of freedom, and even a struggle between freedoms...." **[50](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1E)**. For this reason the word "development" was used in the Encyclical rather than the word "progress," but with an attempt to give the word "development" its fullest meaning. **[51](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1F)**. Encyclical Letter *Populorum Progressio*, n. 19: *loc. cit*., pp. 266f.: "Increased possession is not the ultimate goal of nations or of individuals. All growth is ambivalent.... The exclusive pursuit of possessions thus becomes an obstacle to individual fulfillment and to man's true greatness...both for nations and for individual men, avarice is the most evident form of moral underdevelopment"; cf. also Paul VI, Apostolic Letter *Octogesima Adveniens* (May 14, 1971), n. 9: *AAS* 63 (1971), pp. 407f. **[52](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1G)**.

Praeconium Paschale, *Missale Romanum*, ed. typ. altera, 1975, p. 272: "O certe necessarium Adae peccatum, quod Christi morte deletum est! O felix culpa, quae talem ac tantum meruit habere Redemptorem!" **[57](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1L)**.

Encyclical Letter *Populorum Progressio*, n. 23: *loc. cit.*, p. 268: "If someone who has the riches of this world sees his brother in need and closes his heart to him, how does the love of God abide in him?"(1 Jn 3:17) It is well known how strong were the words used by the Fathers of the Church to describe the proper attitude of persons who possess any thing toward persons in need." In the previous number, the Pope had cited n. 69 of the Pastoral Constitution, *Gaudium et Spes*, of the Second Vatican Ecumenical Council. **[61](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1P)**. Cf. Encyclical Letter *Populorum Progressio*, n. 47: "...a world where freedom is not an empty word and where the poor man Lazarus can sit down at the same table with the rich man." **[62](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1Q)**. Cf. *ibid*., n. 47: "It is a question, rather, of building a world where every man, no matter what his race, religion or nationality, can live a fully human life, freed from servitude imposed on him by other men..."; cf. also Second Vatican Ecumenical Council, Pastoral Constitution on the Church in the Modern World, *Gaudium et Spes*, n. 29. Such fundamental equality is one of the basic reasons why the Church has always been opposed to every form of racism. **[63](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1R)**. Cf. *Homily at Val Visdende* (July 12, 1987), n. 5: *L'Osservatore Romano*, July 13-14, 1987; Paul VI, Apostolic Letter *Octogesima Adveniens* (May 14, 1971), n. 21: *AAS* 63 (1971), pp. 416f. **[64](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1S)**.

Apostolic Exhortation *Reconciliatio et Paenitentia* (December 2, 1984), n. 16: "Whenever the Church speaks of situations of sin, or when she condemns as social sins certain situations or the collective behavior of certain social groups, big or small, or even of whole nations and blocs of nations, she knows and she proclaims that such cases of social sin are the result of the accumulation and concentration of many personal sins. It is a case of the very personal sins of those who cause or support evil or who exploit it; of those who are in a position to avoid, eliminate or at least limit certain social evils but who fail to do so out of laziness, fear or the conspiracy of silence, through secret complicity or indifference; of those who take refuge in the supposed impossibility of changing the world, and also of those who sidestep the effort and sacrifice required, producing specious reasons of a higher order. The real responsibility, then, lies with individuals. A situation - or likewise an institution, a structure, society itself - is not in itself the subject of moral acts. Hence a situation cannot in itself be good or bad": *AAS* 77 (1985), p. 217. **[66](https://www.vatican.va/content/john-paul-ii/en/encyclicals/documents/#-1U)**.
