32 Can anyone, therefore, doubt that laws in favor of divorce would have a result equally baneful and calamitous were they to be passed in these our days? There exists not, indeed, in the projects and enactments of men any power to change the character and tendency with things have received from nature. Those men, therefore, show but little wisdom in the idea they have formed of the well-being of the commonwealth who think that the inherent character of marriage can be perverted with impunity; and who, disregarding the sanctity of religion and of the sacrament, seem to wish to degrade and dishonor marriage more basely than was done even by heathen laws. Indeed, if they do not change their views, not only private families, but all public society, will have unceasing cause to fear lest they should be miserably driven into that general confusion and overthrow of order which is even now the wicked aim of socialists and communists. Thus we see most clearly how foolish and senseless it is to expect any public good from divorce, when, on the contrary, it tends to the certain destruction of society.
