Sollicitudo Rei Socialis §35

³⁵ Precisely because of the essentially moral character of development, it is clear that the obstacles to development likewise have a moral character. If in the years since the publication of Pope Paul's Encyclical there has been no development - or very little, irregular, or even contradictory development - the reasons are not only economic. As has already been said, political motives also enter in. For the decisions which either accelerate or slow down the development of peoples are really political in character. In order to overcome the misguided mechanisms mentioned earlier and to replace them with new ones which will be more just and in conformity with the common good of humanity, an effective political will is needed. Unfortunately, after analyzing the situation we have to conclude that this political will has been insufficient. In a document of a pastoral nature such as this, an analysis limited exclusively to the economic and political causes of underdevelopment (and, mutatis mutandis , of so-called superdevelopment) would be incomplete. It is therefore necessary to single out the moral causes which, with respect to the behavior of individuals considered as responsible persons, interfere in such a way as to slow down the course of development and hinder its full achievement. Similarly, when the scientific and technical resources are available which, with the necessary concrete political decisions, ought to help lead peoples to true development, the main obstacles to development will be overcome only by means of essentially moral decisions. For believers, and especially for Christians, these decisions will take their inspiration from the principles of faith, with the help of divine grace.
