1893 Widespread participation in voluntary associations and institutions is to be encouraged. In accordance with the principle of subsidiarity, neither the state nor any larger society should substitute itself for the initiative and responsibility of individuals and intermediary bodies. 1895 Society ought to promote the exercise of virtue, not obstruct it. It should be animated by a just hierarchy of values. Where sin has perverted the social climate, it is necessary to call for the conversion of hearts and appeal to the grace of God.
Charity urges just reforms.
