Voltaire's opinion of the Bible was mixed. Although influenced by Socinian works such as the Bibliotheca Fratrum Polonorum, Voltaire's skeptical attitude to the Bible separated him from Unitarian theologians like Fausto Sozzini or even Biblical-political writers like John Locke. His statements on religion also brought down on him the fury of the Jesuits and in particular Claude-Adrien Nonnotte. This did not hinder his religious practice, though it did win for him a bad reputation in certain religious circles. The deeply Christian Wolfgang Amadeus Mozart wrote to his father the year of Voltaire's death, saying, "The arch-scoundrel Voltaire has finally kicked the bucket ..." Voltaire was later deemed to influence Edward Gibbon in claiming that Christianity was a contributor to the fall of the Roman Empire in his book "The History of the Decline and Fall of the Roman Empire":As Christianity advances, disasters befall the [Roman empire—arts, science, literature, decay—barbarism and all its revolting concomitants are made to seem the consequences of its decisive triumph—and the unwary reader is conducted, with matchless dexterity, to the desired conclusion—the abominable Manicheism of "Candide", and, in fact, of all the productions of Voltaire's historic school—viz., "that instead of being a merciful, ameliorating, and benignant visitation, the religion of Christians would rather seem to be a scourge sent on man by the author of all evil."
