St. Augustine, to whom Evodius writes all this, acknowledges that there is a great distinction to be made between true and false visions, and that he could wish he had some sure means of discerning them correctly. The same saint relates on this occasion a remarkable story, which has much connection with the matter we are treating upon. A physician named Gennadius, a great friend of St. Augustine's, and well known at Carthage for his great talent and his kindness to the poor, doubted whether there was another life. One day he saw, in a dream, a young man who said to him, "Follow me;" he followed him in spirit, and found himself in a city, where, on his right hand, he heard most admirable melody; he did not remember what he heard on his left.
Another time he saw the same young man, who said to him, "Do you know me?" "Very well," answered he. "And whence comes it that you know me?" He related to him what he had showed him in the city whither he had led him. The young man added, "Was it in a dream, or awake, that you saw all that?" "In a dream?" he replied. The young man then asked, "Where is your body now?" "In my bed," said he. "Do you know that now you see nothing with the eyes of your body?" "I know it," answered he. "Well, then, with what eyes do you behold me?" As he hesitated, and knew not what to reply, the young man said to him, "In the same way that you see and hear me now that your eyes are shut, and your senses asleep; thus after death you will live, you will see, you will hear, but with eyes of the spirit; so doubt not that there is another life after the present one."
The great St. Anthony, one day when he was wide awake, saw the soul of the hermit St. Ammon being carried into heaven in the midst of choirs of angels. Now, St. Ammon died that same day, at five days' journey from thence, in the desert of Nitria. The same St. Anthony saw also the soul of St. Paul Hermitus ascending to heaven surrounded by choirs of angels and prophets. St. Benedict beheld the spirit of St. Germain, Bishop of Capua, at the moment of his decease, who was carried into heaven by angels. The same saint saw the soul of his sister, St. Scholastica, rising to heaven in the form of a dove. We might multiply such instances without end. They are true apparitions of souls separated from their bodies.
