I will not now enter upon the consideration of a multitude of other magic ceremonies, admitted by some Christian sectaries and rejected by others, but to which the devotees who embrace them, attach the most lofty ideas, in the firm persuasion, that God will, on that account, visit them with his invisible grace. All these ceremonies, doubtless, contain great mysteries, and the method of handling or speaking of them is exceedingly mysterious. It is thus that the water on which a priest has pronounced a few words, contained in his conjuring book, acquires the invisible virtue of chasing away wicked spirits, who are invisible by their nature. It is thus that the oil, on which a bishop has muttered some certain formula, becomes capable of communicating to men, and even to some inanimate substances, such as wood, stone, metals, and walls, those invisible virtues which they did not previously possess. In fine, in all the ceremonies of the church, we discover mysteries, and the vulgar, who comprehend nothing of them, are not the less disposed to admire, to be fascinated with, and to respect with a blind devotion. But soon would they cease to have this veneration for these fooleries, if they comprehended the design and end the priests have in view by enforcing their observance.
The priests of all nations have begun by being charlatans, castle builders, divines, and sorcerers. We find men of these characters in nations the most ignorant and savage, where they live by the ignorance and credulity of others. They are regarded by their ignorant countrymen as superior beings, endowed with supernatural gifts, favorites of the very Gods, because the uninquiring multitude see them perform things which they take to be mighty marvellous, or which the ignorant have always considered marvellous. In nations the most polished, the people are always the same; persons the most sensible are not often of the same ideas, especially on the subject of religion; and the priests, authorized by the ancient folly of the multitude, continue their old tricks, and receive universal applause.
You are not, then, to be surprised, Madam, if you still behold our pontiffs and our priests exercise their magical rites, or rear castles before the eyes of people prejudiced in favor of their ancient illusions, and who attach to these mysteries a degree of consequence, seeing they are not in a condition to comprehend the motives of the fabricators. Every thing that is mysterious has charms for the ignorant; the marvellous captivates all men; persons the most enlightened find it difficult to defend themselves against these illusions. Hence you may discover that the priests are always opinionatively attached to these rites and ceremonies of their worship; and it has never been without some violent revolution that they have been diminished or abrogated. The annihilation of a trifling ceremony has often caused rivers of blood to flow. The people have believed themselves lost and undone when one bolder than the rest wished to innovate in matters of religion; they have fancied that they were to be deprived of inestimable advantages and invisible but saving grace, which they have supposed to be attached by the Divinity himself to some movements of the body. Priests the most adroit have overcharged religion with ceremonies, and practices, and mysteries. They fancied that all these were so many cords to bind the people to their interest, to allure them by enthusiasm, and render them necessary to their idle and luxurious existence, which is not spent without much money extracted from the hard earnings of the people, and much of that respect which is but the homage of slaves to spiritual tyrants.
