The injustice of certain situations cries out for God’s attention. Lacking the bare necessities of life, whole nations are under the thumb of others; they cannot act on their own initiative; they cannot exercise personal responsibility; they cannot work toward a higher degree of cultural refinement or a greater participation in social and public life. They are sorely tempted to redress these insults to their human nature by violent means.
Everyone knows, however, that revolutionary uprisings—except where there is manifest, longstanding tyranny which would do great damage to fundamental personal rights and dangerous harm to the common good of the country—engender new injustices, introduce new inequities and bring new disasters. The evil situation that exists, and it surely is evil, may not be dealt with in such a way that an even worse situation results.
We want to be clearly understood on this point: The present state of affairs must be confronted boldly, and its concomitant injustices must be challenged and overcome. Continuing development calls for bold innovations that will work profound changes. The critical state of affairs must be corrected for the better without delay.
Everyone must lend a ready hand to this task, particularly those who can do most by reason of their education, their office, or their authority. They should set a good example by contributing part of their own goods, as several of Our brother bishops have done. In this way they will be responsive to men’s longings and faithful to the Holy Spirit, because “the ferment of the Gospel,” too, has aroused and continues to arouse in man’s heart the irresistible requirements of his dignity. –from Populorum Progressio (1967)
