“The short space of threescore years can never content the imagination of man; nor can the imperfect joys of this world satisfy his heart. Man alone, of all created beings, displays a natural contempt of existence, and yet a boundless desire to exist; he scorns life, but he dreads annihilation. These different feelings incessantly urge his soul to the contemplation of a future state, and religion directs his musings thither. Religion, then, is simply another form of hope, and it is no less natural to the human heart than hope itself. Men cannot abandon their religious faith without a kind of aberration of intellect and a sort of violent distortion of their true nature; they are invincibly brought back to more pious sentiments. Unbelief is an accident, and faith is the only permanent state of mankind. If we consider religious institutions merely in a human point of view, they may be said to derive an inexhaustible element of strength from man himself, since they belong to one of the constituent principles of human nature.
I am aware that at certain times religion may strengthen this influence, which originates in itself, by the artificial power of the laws and by the support of those temporal institutions that direct society. Religions intimately united with the governments of the earth have been known to exercise sovereign power founded on terror and faith; but when a religion contracts an alliance of this nature, I do not hesitate to affirm that it commits the same error as a man who should sacrifice his future to his present welfare; and in obtaining a power to which it has no claim, it risks that authority which is rightfully its own. When a religion founds its empire only upon the desire of immortality that lives in every human heart, it may aspire to universal dominion; but when it connects itself with a government, it must adopt maxims which are applicable only to certain nations. Thus, in forming an alliance with a political power, religion augments its authority over a few and forfeits the hope of reigning over all.
As long as a religion rests only upon those sentiments which are the consolation of all affliction, it may attract the affections of all mankind. But if it be mixed up with the bitter passions of the world, it may be constrained to defend allies whom its interests, and not the principle of love, have given to it; or to repel as antagonists men who are still attached to it, however opposed they may be to the powers with which it is allied. The church cannot share the temporal power of the state without being the object of a portion of that animosity which the latter excites.”
