an excerpt from the chapter: THE DIVINE MYSTERY 1. The first author to invent the word Demoniality was no doubt John Caramuel, in his "Fundamental Theology." Before him there is no one who is known to have distinguished that crime from Bestiality. All theological moralists, following in the train of St. Thomas, include, under the specific beastiality, "every kind of carnal intercourse with anything whatever of a different species." Such are the words used by St. Thomas. Cajetanus, for instance, in his commentary on that question, classes intercourse with the Demon under the description of beastiality; so does Sylvester, "De Luxuria," Bocancia, "De Matrimonio." 2. However, it is clear that in the above passage St. Thomas did not at all allude to intercourse with the Demon. As shall be demonstrated further on, that intercourse cannot be included in the very particular species of beastiality; and in order to make that sentence of the holy doctor tally with truth, it must be admitted that when saying of the natural sin, "that committed through the intercourse with a thing of different species, takes the name of beastiality." St. Thomas, by a thing of different species, means a living animal of another species than man; for he could not here use the word this in the most general sense, to mean indiscriminately an animate or inanimate being. In fact, if a man should fornicate cum cadavere human he would have to do with a thing of a species quite different from his own; similarly si cadaveri beastiali copularetur; and yet, talis coitus would not be beastiality, but pollution. What, therefore, St. Thomas intended here to specify with preciseness is carnal intercourse with a living thing of a species different from that of man, that is to say, with a beast, and he never in the least thought of intercourse with the Demon.
