WHEN Voltaire was born, the natural was about the only thing in which the church did not believe. The monks sold little amulets of consecrated paper. They would cure diseases. If laid in a cradle they would prevent a child being bewitched. So, they could be put into houses and barns to keep devils away, or buried in a field to prevent bad weather, to delay frost, and to insure good crops. There was a regular formulary by which they were made, ending with a prayer, after which the amulets were sprinkled with holy water. The church contended that its servants were the only legitimate physicians. The priests cured in the name of the church, and in the name of God, by exorcism, relics, water, salt, and oil. St. Valentine cured epilepsy, St. Gervasius was good for rheumatism, St. Michael de Sanatis for cancer, St. Judas for coughs, St. Ovidius for deafness, St. Sebastian for poisonous bites, St. Apollonia for toothache, St. Clara for rheum in the eye, St. Hubert for hydrophobia. Devils were driven out with wax tapers, with incense, with holy water, by pronouncing prayers. The church, as late as the middle of the twelfth century, prohibited good Catholics from having anything to do with physicians. It was believed that the devils produced storms of wind, of rain and of fire from heaven; that the atmosphere was a battlefield between angels and devils; that Lucifer had power to destroy fields and vineyards and dwellings, and the principal business of the church was to protect the people from the Devil. This was the origin of church bells. These bells were sprinkled with holy water, and their clangor cleared the air of imps and fiends. The bells also prevented storms and lightning. The church used to anathematize insects. In the sixteenth century, regular suits were commenced against rats, and judgment was rendered. Every monastery had its master magician, who sold magic incense, salt, and tapers, consecrated palms and relics. Every science was regarded as an outcast, an enemy. Every fact held the creed of the church in scorn. Investigators were enemies in disguise. Thinkers were traitors, and the church exerted its vast power for centuries to prevent the intellectual progress of man. There was no liberty, no education, no philosophy, no science; nothing but credulity, ignorance, and superstition. The world was really under the control of Satan and his agents. The church, for the purpose of increasing her power, exhausted every means to convince the people of the existence of witches, devils, and fiends. In this way the church had every enemy within her power. She simply had to charge him with being a wizard, of holding communication with devils, and the ignorant mob were ready to tear him to pieces.
