It must be owned that, out of a hundred of these pretended appearances, hardly two will be found to be true. The ancients are not more to be credited on that point than the moderns, since they were, at least, equally as credulous as people are in our own age, or rather they were more credulous than we are at this day. I grant that the foolish credulity of the people, and the love of everything that seems marvelous and extraordinary, have produced an infinite number of false histories on the subject we are now treating of. There are here two dangers to avoid: a too great credulity, and an excessive difficulty in believing what is above the ordinary course of nature; as likewise, we must not conclude what is general from what is particular, or make a general case of a particular one, nor say that all is false because some stories are so; also, we must not assert that such a particular history is a mere invention, because there are many stories of this latter kind. It is allowable to examine, prove, and select; we must never form our judgment but with knowledge of the case; a story may be false in many of its circumstances (as related), but true in its foundation. The history of the deluge, and that of the passage across the Red Sea, are certain in themselves, and in the simple and natural recital given of them by Moses. The profane historians, and some Hebrew writers, and even Christians, have added some embellishment which must militate against the story in itself. Josephus the historian has much embellished the history of Moses; Christian authors have added much to that of Josephus; the Mahometans have altered several points of the sacred history of the Old and New Testament. Must we, on this account, consider these histories as problematical? The life of St. Gregory Thaumaturgus is full of miracles, as are also those of St. Martin and St. Bernard. St. Augustine relates several miraculous cures worked by the relics of St. Stephen. Many extraordinary things are related in the life of St. Ambrose. Why not give faith to them after the testimony of these great men, and that of their disciples, who had lived with them, and had been witnesses of a good part of what they relate? It is not permitted us to dispute the truth of the apparitions noted in the Old and New Testament; but we may be permitted to explain them. For instance, it is said that the Lord appeared to Abraham in the valley of Mamre;[417] that he entered Abraham's tent, and that he promised him the birth of a son; also, it is allowed that he received three angels, who went from thence to Sodom. St. Paul[418] notices it expressly in his Epistle to the Hebrews; _angelis hospitio receptis_. It is also said that the Lord appeared unto Moses, and gave him the law; and St. Stephen, in the Acts,[419] informs us that it was an angel who spoke to him from the burning bush, and on Mount Horeb; and St. Paul, writing to the Galatians, says, that the law was given by angels.[420]
