Ad Petri Cathedram §128

¹²⁸ We ask these dear children of Ours to realize that the Church is not hostile to them or their rights. On the contrary, she cares for them as would a loving mother. She preaches and inculcates a social doctrine and social norms which would eliminate every sort of injustice and produce a better and more equitable distribution of goods, if they were put into practice as they should be. (64) At the same time, she encourages friendly cooperation and mutual assistance among the various classes, so that all men may become in name and in fact not only free citizens of the same society but also brothers within the same family.
