19 Especially must there be appeals to the kindly assistance of those whose rank, wealth, and intellectual as well as spiritual culture give them a certain standing in the community. If their help is not extended, scarcely anything can be done which will help in promoting the well-being of the people. Assuredly, the more earnestly many of those who are prominent citizens conspire effectively to attain that object, the quicker and surer will the end be reached. We would, however, have them understand that they are not at all free to look after or neglect those who happen to be beneath them, but that it is a strict duty which binds them. For, no one lives only for his personal advantage in a community; he lives for the common good as well, so that, when others cannot contribute their share for the general good, those who can do so are obliged to make up the deficiency. The very extent of the benefits they have received increases the burden of their responsibility, and a stricter account will have to be rendered to God who bestowed those blessings upon them. What should also urge all to the fulfillment of their duty in this regard is the widespread disaster which will eventually fall upon all classes of society if his assistance does not arrive in time; and therefore is it that he who neglects the cause of the distressed masses is disregarding his own interest as well as that of the community.
