You are not formed to be the dupe of names and authorities. The defenders of the popular superstition will endeavor to overwhelm you by the multiplied testimony of many illustrious and learned men, who not only admitted the Christian religion, but who were also its most zealous supporters. They will adduce holy divines, great philosophers, powerful reasoners, fathers of the church, and learned interpreters, who have successively advocated the system. I will not contest the understanding of the learned men who are cited, which, however, was often faulty, but will content myself with repeating that frequently the greatest geniuses are not more clear sighted in matters of religion than the people themselves. They did not examine the religious opinions they taught; it may be because they regarded them as sacred, or it may be because they never went back to first principles, which they would have found altogether unsound, if they had considered them without prejudice. It may also have happened because they were interested in defending a cause with which their own position was allied. Thus their testimony is exceptionable, and their authority carries no great weight. With regard to the interpreters and commentators, who for so many ages have painfully toiled to elucidate the divine laws, to explain the sacred books, and to fix the dogmas of Christianity, their very labors ought to inspire us with suspicion concerning a religion which is founded upon such books and which preaches such dogmas. They prove that works emanating from the Supreme Being are obscure, unintelligible, and need human assistance in order to be understood by those to whom the Divinity wished to reveal his will. The laws of a wise God would be simple and clear. Defective laws alone need interpreters.
