“Our Name Is Legion”
Men have believed hitherto that there is some one devil who is over the hells, and that he was created an angel of light; but that after he turned rebel, he was cast down with his crew into hell. Men have had this belief because the Devil is named in the Word, and Satan, and also Lucifer, and in these passages the Word has been understood according to the sense of the letter, when yet hell is meant in them by the Devil and Satan.... That there is no single Devil to whom the hells are subject, is also evident from this fact, that all who are in the hells, like all who are in the heavens, are from the human race; and that from the beginning of the creation to this time they amount to myriads of myriads, every one of whom is a devil of a sort according with his opposition to the Divine in the world.
