The Jews, besides their public code of revelation, had their Urim and Thummim for the particulars of duty. Is it certain? Is it even rational to suppose that the few answers of that oracle mentioned in the scriptures, are the only ones ever communicated? Prophets, too, were sent to manifest the particulars of duty, and angels, some of whom _might be_ the spirits of just men. And we have no reason to doubt but Moses was a Spectre when he conversed with Christ on the Holy Mount; notwithstanding that old fiction of his resurrection, which has dishonored the antiquities of Josephus. Now the question is, what person ever yet demonstrated that no such occasional revelation was ever wanted in any hour since the completion of the scriptures? Certainly this completion never precluded spectral missions in the view of the christian fathers. And their continuation has been the constant faith of christians in general, down to this day of deism. And the war of the deists against this opinion is easily accounted for: because the admission of Spectres is the admission of miracle; and the admission of occasional revelation, brings a question to their door which would be a troublesome neighbor. _Why then should not a revelation be needful for the public?_ Great is their obligation to modern christians for their assistance in this warfare. It may be asked, if these missions have been thus continued, why have they generally been attended with so few witnesses? But if there be evidence enough for him, or those who are interested in the message, it is sufficient for their purpose, whether others believe it or not. When David was told by the Urim that the men of Keilah would deliver him into the hand of Saul, no person appears to have been present but Abiather; but if the oracle was attended with the evidence described by Josephus, there was evidence enough for the purpose of David and his men, whether five other persons in the whole nation believed it or not. After all, it is not our duty to expect apparitions, for they never come to gratify curiosity; nor to pray for their coming, unless our case be peculiar as that of Manoah; nor to entertain the idea that their speaking to us, would make a more durable impression than the preaching of the living. Such conduct and apprehensions are erroneous, and expose us to greater delusion. Our Lord has expressly taught us that, if we believe not Moses and the prophets, neither shall we be persuaded, though one rose from the dead. And accordingly the affectionate and persuasive addresses of the Spectre in this place, which drew tears from every eye, had no happy, durable influence on the unregenerate character in a single instance.
