In his "Testament", Meslier repudiated not only the God of conventional Christianity, but even the generic God of the natural religion of the deists. For Meslier, the existence of evil was incompatible with the idea of a good and wise God. He denied that any spiritual value could be gained from suffering, and he used the deist's argument from design against god, by showing the evils that he had permitted in this world. To him, religions were fabrications fostered by ruling elites; although the earliest Christians had been exemplary in sharing their goods, Christianity had long since degenerated into encouraging the acceptance of suffering and submission to tyranny as practised by the kings of France: injustice was explained away as being the will of an all-wise Being. None of the arguments used by Meslier against the existence of God were original. In fact, he derived them from books written by orthodox theologians in the debate between the Jesuits, Cartesians, and Jansenists. Their inability to agree on a proof for God's existence was taken by Meslier as a good reason not to presume that there were compelling grounds for belief in God.
