That persecution is necessarily ingrained in priests of every denomination, and that they will have recourse to it whenever they have the power, we have a memorable instance in the much vaunted reformer, John Calvin, who, when armed with authority by the magistrates of Geneva, wrote to the high Chamberlain of the King of Navarre, (of date the 30th Sept., 1561) as follows:--"Honor, glory, and riches, shall be the reward of your pains; but, above all, do not fail to rid the country of those zealous scoundrels who stir up the people to revolt against _us_. Such monsters should be exterminated, as I have exterminated Michael Servetus, the Spaniard." Now the fact is well known, that when Calvin found himself unable to cope in argument with this learned Spaniard, he took the true orthodox way of getting a riddance, by roasting him alive at a slow fire, _inhumanly made on purpose, of green wood._ The intrepid Bruno resolutely suffered at the stake for condemning that baleful source of distraction to the human race--the spirituality of priests. In latter times matters are not much mended. A considerable portion of the 19th century has now elapsed, and has been deemed a period of science; yet free discussion, and the exercise of reason on all subjects have made but small progress; and it is melancholy to reflect that plain truth is still at the bottom of her well, where she is stifled by the demon of supernatural theology and its political colleagues, from whence she has been suffered to emit only partial glimmerings of light; whilst, from base interest, she is shunned or unacknowledged by those very men of science by whom alone she can be rescued from this detestable thraldom of the mind. By corrupt judges and packed juries she is jealously excluded from courts of pretended justice, lest she should expose, in her odious colors, the reigning hag of superstition, with her Bibyline books of mystery and fraud; hence the fines, the robberies, and the incarcerations of a great number of the most virtuous, enlightened, and most talented advocates of free discussion and mental liberty, for the last thirty years. Thus has the peace of countries been incessantly disturbed and outraged, for nearly two thousand years, by this strange fabrication of artificial theology; thus has it been perpetually in exercise as an instrument in the persecution of great and good men, and raised up the most inextinguishable flames of hatred, wars, and devastations amongst nations. Such will ever be its effects, particularly where it is iniquitously upheld as a device to strangle mental liberty, through the hopes and fears of ignorance; and as an engine of state to sustain corrupt government.
