Such are the important services which religion has a thousand times rendered to kings. The people, blinded by superstition, could hesitate but little between God and the princes of the earth. The priests, being the visible organs of an invisible monarch, have acquired an immense credit with prejudiced minds. The ignorance of the people places them, as well as their sovereigns, at the mercy of the priests. Nations have continually been dragged into their futile though bloody quarrels; princes, for a long series of years, have either had to dispute their authority with the clergy, or become their tools or dupes.

The continual attention which the princes of Europe have been forced to pay to the clergy has prevented them from occupying their thoughts about the welfare of their subjects, who, in many instances the dupes of the priesthood, have opposed even the good their rulers desired to procure them. In like manner, the heads of the people, their kings and governors, too weak to resist the torrent of opinions propagated by the clergy, have been forced to yield, to bow, nay, even to caress the priesthood, and to consent to grant it all its demands. Whenever they have wished to resist the encroachments of the clergy, they have encountered concealed snares or open opposition, as the _holy_ power was either too weak to act in the face of day, or strong enough to contend in the sunshine. When princes have wished to be listened to by the clergy, these last have invariably contrived to make them cowardly, and to sacrifice the happiness and respect of their people. Often have the hands of parricides and rebels been armed, by a proud and vindictive priesthood, against sovereigns the most worthy of reigning. The priests, under pretext of avenging God, inflict their anger upon monarchs themselves, whenever the latter are found indisposed to bend under their yoke. In a word, in _all_ countries we perceive that the ministers of religion have exercised in all ages the most unbridled license. We every where see empires torn by their dissensions; thrones overturned by their machinations; princes immolated to their power and revenge; subjects animated to revolt against the prince that ought to give them more happiness than they actually enjoyed; and when we take the retrospect of these, we find that the ambition, the cupidity, and vanity of the clergy have been the true causes and motives of all these outrages on the peace of the universe. And it is thus that their religion has so often produced anarchy, and overturned the very empires they pretended to support by its influence.
