“We are not surprised at the corruption which Christianity has undergone. Christianity itself, as we have already seen, foretold it; and the doctrine of human depravity fully accounts for it. When the Christian religion was adopted by the state, it is natural to suppose there were great numbers of unprincipled men who professed it; and where its leading characters in any age are of this description, it will certainly be corrupted. The pure doctrine of Christ is given up in favour of some flesh-pleasing system, the holy precepts of Christian morality are lowered to the standard of ordinary practice, and the worship and ordinances of Christ are mingled with superstition, and modelled to a worldly temper. It was thus that Judaism was corrupted by the old Pharisees, and Christianity by the papal hierarchy.
The success with which evil men and seducers meet, in propagating false doctrine, is no more than, from the present state of things, may be expected. So long as a large proportion of the professors of Christianity receive not the love of the truth, error will be certain to meet with a welcome reception. The grossest impostor has only to advance a system suited to corrupt nature, to assert it with effrontery, and to flatter his adherents with being the favourites of heaven, and he will be followed.”
