The first of the Christian virtues is faith, which serves as a foundation for all the others. It consists in an impossible conviction of the revealed doctrines and absurd fables which the Christian religion commands its disciples to believe. Hence it appears that this virtue exacts a total renunciation of reason, and impracticable assent to improbable facts; and a blind submission to the authority of priests, who are the only guarantees of the truth of the doctrines and miracles that every Christian must believe under penalty of damnation. This virtue, although necessary to all mankind, is nevertheless, a gift of Heaven, and the effect of a special grace. It forbids all doubt and enquiry; and it deprives man of the liberty of exercising his reason and reflection. It reduces him to the passive acquiescence of beasts in matters which he is, at the same time, told are of all things the most important to his happiness. Hence it is plain, that faith is a virtue invented by men, who, shrinking from the light of reason, deceived their fellow-creatures, to subject them to their own authority, and degraded them that they might exercise an empire over them. If faith be a virtue, it is certainly useful only to the spiritual guides of the Christians, for they alone gather its fruits. It cannot but be injurious to other men, who are taught by it to despise that reason, which distinguishes them from brutes, and is their only faithful guide in this world. Christians, however, represent this reason as perverted, and as unfaithful guide; by which they seem to intimate that it was not made for reasonable beings. May we not, however, ask them how far this renunciation of reason ought to be carried? Do not they themselves, in certain cases, have recourse to reason? Do they not appeal to reason, when they endeavour to prove the existence of their God? Be this as it may, it is an absurdity to say we believe that of which we have no conception. What, then, are the motives of the Christian, for pretending to such a belief? His confidence in his spiritual guides. But what is the foundation of this confidence? Revelation. On what, then, is Revelation itself founded? On the authority of spiritual guides. Such is the manner in which Christians reason. Their arguments in favour of faith are comprised in the following sentence. To believe our religion it is necessary to have faith, and to have faith you must believe in our religion. Or, it is necessary to have faith already, in order to believe in the necessity of faith.1
