The devil could transport men, at his will, through the air. He could beget children; and Martin Luther himself had come in contact with one of these children. He recommended the mother to throw the child into the river, in order to free their house from the presence of a devil. It was believed that the devil could transform people into any shape he pleased. Whoever denied these things was denounced as an infidel. All the believers in witchcraft confidently appealed to the bible. Their mouths were filled with passages demonstrating the existence of witches and their power over human beings. By the bible they proved that innumerable evil spirits were ranging over the world endeavoring to ruin mankind; that these spirits possessed a power and wisdom far transcending the limits of human faculties; that they delighted in every misfortune that could befall the world; that their malice was superhuman. That they caused tempests was proved by the action of the devil toward Job; by the passage in the book of Revelation describing the four angels who held the four winds, and to whom it was given to afflict the earth. They believed the devil could carry persons hundreds of miles, in a few seconds, through the air. They believed this, because they knew that Christ had been carried by the devil in the same manner and placed on a pinnacle of the temple. "The prophet Habakkuk had been transported by a spirit from Judea to Babylon; and Philip, the evangelist, had been the object of a similar miracle; and in the same way Saint Paul had been carried in the body into the third heaven." "In those pious days, they believed that _Incubi_ and _Succubi_ were forever wandering among mankind, alluring, by more than human charms, the unwary to their destruction, and laying plots, which were too often successful, against the virtue of the saints. Sometimes the witches kindled in the monastic priest a more terrestrial fire. People told, with bated breath, how, under the spell of a vindictive woman, four successive abbots in a German monastery had been wasted away by an unholy flame." An instance is given in which the devil not only assumed the appearance of a holy man, in order to pay his addresses to a lady, but when discovered, crept under the bed, suffered himself to be dragged out, and was impudent enough to declare that he was the veritable bishop. So perfectly had he assumed the form and features of the prelate that those who knew the bishop best were deceived. One can hardly imagine the frightful state of the human mind during these long centuries of darkness and superstition. To them, these things were awful and frightful realities. Hovering above them in the air, in their houses, in the bosoms of friends, in their very bodies, in all the darkness of night, everywhere, around, above and below, were innumerable hosts of unclean and malignant devils.
