Informant38

Religion has been, he says, corrupted by the wickedness of those to whom it was communicated, and has lost part of its efficacy, by its connexion with temporal interest and human passion.

He justly observes, that from all this no conclusion can be drawn against the divine original of Christianity, since the objections arise not from the nature of the revelation, but of him to whom it is communicated.

All this is known, and all this is true; but why, we have not yet discovered. Our author, if I understand him right, pursues the argument thus: the religion of man produces evils, because the morality of man is imperfect; his morality is imperfect, that he may be justly a subject of punishment; he is made subject to punishment, because the pain of part is necessary to the happiness of the whole; pain is necessary to happiness, no mortal can tell why, or how.

Thus, after having clambered, with great labour, from one step of argumentation to another, instead of rising into the light of knowledge, we are devolved back into dark ignorance; and all our effort ends in belief, that for the evils of life there is some good reason, and in confession, that the reason cannot be found. This is all that has been produced by the revival of Chrysippus's untractableness of matter, and the Arabian scale of existence. A system has been raised, which is so ready to fall to pieces of itself, that no great praise can be derived from its destruction. To object, is always easy, and, it has been well observed by a late writer, that "the hand which cannot build a hovel, may demolish a temple."
