Unfortunately, fatally for the liberties of France, the leading writers were infidels. Mistaking the corruptions of Christianity for Christianity itself, they assailed religion furiously, and succeeded in eradicating from men's souls all apprehensions of responsibility to God. Nothing could more effectually brutalize and demonize the soul of man. And yet the Papal Church, as a towering hierarchy, had become so corrupt, such an instrument of oppression, and such a support of despotism, that no reform could have been accomplished but by its overthrow.[28] It was the monarch's right arm of strength; it was the rampart which was first to be battered down. The Church had no word of censure for vice in high places. It spread its shield before the most enormous abuses, and, by its inquisitorial censorship of the press, protected the most execrable institutions. The Church, enervated by wealth and luxurious indulgence, had also become so decrepit as to invite attack. No man could summon sufficient effrontery to attempt her defense. The only reply which bloated and debauched ecclesiastics could make to their assailants was persecution and the dungeon. There were a few truly pious men in the Church; they did, however, but exhibit in clearer contrast the general corruption with which they were surrounded. Diderot, though educated by the Jesuits--perhaps _because_ he was educated by the Jesuits--commenced his career by an attack upon Christianity in his _Pensées Philosophiques_. He was sent to prison, and his book burned by the public executioner. Still, multitudes read and so warmly applauded that he was incited to form the plan of the celebrated Encyclopedia which was to contain a summary of all human knowledge. In this grand enterprise he allied with him the ablest scholars and writers of the day--Mably, Condillac, Mercier, Raynal, Buffon, Helvetius, D'Alembert, and others. Nearly all these men, despising the _Church_, were unbelievers in _Christianity_. They consequently availed themselves of every opportunity to assail religion. The court, alarmed, laid a prohibition upon the work, but did not dare to punish the writers, as they were too numerous and powerful. Thus infidelity soon became a fashion. Notwithstanding the prohibition, the work was soon resumed, and became one of the most powerful agents in ushering in the Revolution. "Christianity was hated by these philosophers," writes De Tocqueville, "less as a religious doctrine than as a political institution; not because the ecclesiastics assumed to regulate the concerns of the other world, but because they were landlords, seigneurs, tithe-holders, administrators in this; not because the Church could not find a place in the new society which was being established, but because she then occupied a place of honor, privilege, and might in the society which was to be overthrown."
