Pius XI, 1922-1939

2269. The guiding principle of economics to be restored. Still another matter, closely connected with the former, must be kept in mind. Just as the unity of society cannot rest on mutual opposition of classes, so the right ordering of economic affairs cannot be given over to the free competition of forces . . . Therefore, higher and more noble principles are to be sought, with which to control this power firmly and soundly; namely, social justice and social charity.

Rom. 13:1] he may develop and evolve fully all his faculties to the praise and glory of his Creator; and by faithfully performing the duty of his trade, or of any other vocation, he may acquire for himself both temporal and eternal happiness. Socialism, however, entirely ignorant of this sublime end both of man and of society, and unconcerned about it, affirms that human society was instituted for material advantages alone. . . . Catholic and socialist have contradictory meanings. But if socialism,
