When Voltaire was born there was really but one church which, of course, was ignorant, tyrannical and barbarous in the extreme. All creeds are alike, and whenever there is but one, and the rulers honestly believe in that one, they are bound to be ignorant, barbarous and cruel. All sorts of heresies were punishable by death. If anyone dared to write a pamphlet or book that questioned any part of the accepted faith, the book was at once consigned to flames and the author was lucky if he did not meet the same fate. Religion was not maintained by the precepts of the priest, but by the prison, the torture chamber and the fagot. Everyone believed; no one questioned. The religious creeds, while strict and barbarous, did not interfere with the personal conduct of any of the rulers. They were left free to act as they pleased, so long as they professed to believe in the prevailing faith.
