Whence I conclude, that the Hebrews had no doubt that the spirits of the dead could return to earth, that they did return in fact, and that they discovered to the living things beyond our natural knowledge. Moses expressly forbids the Israelites to consult the dead.[339] But these apparitions did not show themselves in solid and material bodies; the Saviour assures us of it when he says, "Spirits have neither flesh nor bones." It was often only an aerial figure which struck the senses and the imagination, like the images which we see in sleep, or that we firmly believe we hear and see. The inhabitants of Sodom were struck with a species of blindness,[340] which prevented them from seeing the door of Lot's house, into which the angels had entered. The soldiers who sought for Elisha were in the same way blinded in some sort,[341] although they spoke to him they were seeking for, who led them into Samaria without their perceiving him. The two disciples who went on Easter-day to Emmaus, in company with Jesus Christ their Master, did not recognize him till the breaking of the bread.[342] Thus, the apparitions of spirits to mankind are not always in a corporeal form, palpable and real; but God, who ordains or permits them, often causes the persons to whom these apparitions appear, to behold, in a dream or otherwise, those spirits which speak to, warn, or threaten them; who makes them see things as if present, which in reality are not before their eyes, but only in their imagination; which does not prove these visions and warnings not to be sent from God, who, by himself, or by the ministration of his angels, or by souls disengaged from the body, inspired the minds of men with what he judges proper for them to know, whether in a dream, or by external signs, or by words, or else by certain impressions made on their senses, or in their imagination, in the absence of every external object. If the apparitions of the souls of the dead were things in nature and of their own choice, there would be few persons who would not come back to visit the things or the persons which have been dear to them during this life. St. Augustine says it of his mother, St. Monica,[343] who had so tender and constant an affection for him, and who, while she lived, followed him and sought him by sea and land. The bad rich man would not have failed, either, to come in person to his brethren and relations to inform them of the wretched condition in which he found himself in hell. It is a pure favor of the mercy or the power of God, and which he grants to very few persons, to make their appearance after death; for which reason we should be very much on our guard against all that is said, and all that we find written on the subject in books.
