According to the very principles either of natural or revealed theology, every new revelation should be regarded as false; every change in a religion emanated from the Deity should be reputed an impiety and blasphemy. Does not all reform suppose, that, in his first effort, God could not give his religion the solidity and perfection required? To say, that God, in giving a first law, conformed to the rude ideas of the people whom he wished to enlighten, is to pretend that God was neither able nor willing to render the people, whom he was enlightening, so reasonable as was necessary in order to please him.

Christianity is an impiety, if it is true that Judaism is a religion which has really emanated from a holy, immutable, omnipotent, and foreseeing God. The religion of Christ supposes either defects in the law which God himself had given by Moses, or impotence or malice in the same God, who was either unable or unwilling to render the Jews such as they ought to have been in order to please him. Every new religion, or reform of ancient religions, is evidently founded upon the impotence, inconstancy, imprudence, or malice of the Divinity.
