Another very important consideration, is, that, in urging the duty of charity, and the prior claims of moral and religious objects, no rule of duty should be maintained, which it would not be right and wise for _all_ to follow. And we are to test the wisdom of any general rule, by inquiring what would be the result, if all mankind should practise according to it. In view of this, we are enabled to judge of the correctness of those, who maintain, that, to be consistent, men believing in the eternal destruction of all those of our race who are not brought under the influence of the Christian system, should give up, not merely the elegances, but all the superfluities, of life, and devote the whole of their means, not indispensable to life and health, for the propagation of Christianity. But, if this is the duty of any, it is the duty of all; and we are to inquire what would be the result, if all conscientious persons gave up the use of all superfluities. Suppose, that two millions of the people in the United States, were conscientious persons, and relinquished the use of every thing not absolutely necessary to life and health. It would instantly throw out of employment one half of the whole community. The manufacturers, mechanics, merchants, agriculturists, and all the agencies they employ, would be beggared, and one half of those not reduced to poverty, would be obliged to spend all their extra means, in simply supplying necessaries to the other half. The use of superfluities, therefore, to a certain extent, is as indispensable to promote industry, virtue, and religion, as any direct giving of money or time; and it is owing entirely to a want of reflection, and of comprehensive views, that any men ever make so great a mistake, as is here exhibited.
