[T]hey take occasion to revile the Christian religion, because they misunderstand it. They imagine that it consists simply in the worship of a God considered as great, powerful, and eternal; which is strictly deism, almost as far removed from the Christian religion as atheism, which is its exact opposite. And thence they conclude that this religion is not true, because they do not see that all things concur to the establishment of this point, that God does not manifest Himself to men with all the evidences which He could show.

But let them conclude what they will against deism, they will conclude nothing against Christian religion, which properly consists in the mystery of the Redeemer, who, uniting in Himself the two natures, human and divine, has redeemed men from the corruption of sin in order to reconcile them in His divine person of God.

The Christian religion then teaches men to hear two truths; that there is a God whom men can know, and that there is a corruption in their nature which renders them unworthy of Him. It is equally important to men to know both these points; and it is equally dangerous for man to know God without knowing his own wretchedness, and to to know his own wretchedness without knowing the Redeemer who can free him from it. The knowledge of one of these points gives either to the pride of philosophers, who have known God, and not their own wretchedness, or to the despair of atheists, who know their own wretchedness, but not the Redeemer.
