The difference is seen very clearly by looking at the argument which Butler’s reasoning is intended to confute. Suppose a professed revelation to be laid before a person who was before unacquainted with it, and that he finds in it several perplexing points. According to Butler’s principle, or what is supposed by Mr. Rogers to be Butler’s principle, it is enough to reply: You have those same difficulties in nature before; you cannot consistently object to them now; they have not prevented your ascribing nature to a Divine Author; they should not prevent you from ascribing to Him this revelation. Nature is so full of difficulties, that almost every doctrine that has ever been attributed to revelation may be provided with a parallel more or less apt. Consequently, it would be almost needless to criticise the contents of any alleged revelation, when we may be met so easily by such a reply. No careful reasoner would attempt that criticism. According to the doctrine which we have reiterated, we should deem it a difficulty that these perplexing points should be found in a revelation; but that difficulty would not amount to much, would not counterbalance strong evidence, if it could be shown that the system claiming to be revealed, although leaving these points unexplained, threw ample light on others; that what gave cause for perplexity was quite subordinate to what removed perplexity; that no immoral actions were enjoined on man; no unworthy motives imputed to God; no vice attributed to the whole scheme and plan of the Creator. There would therefore remain the largest scope for internal criticism on all systems claiming to be messages from God; on the very face they must seem worthy of Him: in their very essence they must seem good. This is plainly the obvious view. The natural opinion certainly is that the moral and religious faculties would be those on which we should primarily depend, in judging of an alleged communication from heaven; in deciding whether it have a valid claim to that character or no. These faculties are those which, antecedently to revelation, determine our belief in all other moral and religious questions, and it is therefore natural to look to them as the best judges of the authenticity of an alleged revelation. Many divines, however, struggle to deny this. Thus, in the memoir of Butler we are now reviewing, Mr. Rogers observes,—
