[On the respective roles of Church and State in the lives of citizens]
 Nonetheless, the agencies of the Church and those of civil society should be united in their common concern, so that the greatest good can be achieved. Therefore we should consider what role the State can justly play in providing relief.  The State, properly speaking, refers not to any particular form of government but to any government conformable to right reason, natural law, and the dictates of Divine law, as set out in the encyclical On the Christian Constitution of the State [see also Catholic Encyclopedia online]. Its chief duty is to make sure that its laws and institutions promote and protect public well-being and private prosperity; this being so, it should promote everything that makes its citizens better and happier, including public morality, well-ordered family life, respect for religion and justice, moderate taxation, productive use of land, etc. If these things are seen to, there will be fewer poor and less need for public relief.
 While, as we have said, the State must not absorb the individual or the family, nonetheless it should show a paternal interest in the well-being of its individual members, just as it should safeguard the commonwealth as a whole.  Since the State’s responsibility is to secure the public good, it may intervene in public or private affairs when that general good is threatened by circumstances or events; for instance, when workers are not afforded time to carry out familial or religious duties, or if they are required to work in unhealthy or immoral conditions, or if a threatened labor strike would endanger the public peace. In such cases, the law may intervene, provided that it do no more than required to remedy the situation.
 While all legitimate human rights must be protected by law, the poor and the needy should be especially protected, since they have no resources to fall back on as the rich do, aside from the State’s assistance.  Nonetheless, the right to private property must be protected by law, nor should private property be seized and redistributed under pretext of justice.  The State should ensure humane working conditions and reasonable pay, in order to forestall workers' strikes, because the disruptions caused by strikes are injurious to the public peace.
 The human condition of workers should be respected, in such a way that they are not used simply as tools to create profit for their greedy employers. Therefore, the hours and conditions of work should not be so taxing as to work men beyond their endurance, nor should women and children be required to work as long or as hard as grown men, and all workers should be given enough time off to recuperate from their labors. Even if workers and employers should agree on conditions that would make no allowance for man’s duty to God and himself, doing so would be wrong.
