It is with reason that obsessions and possessions of the devil are placed in the rank of apparitions of the evil spirit among men. We call it _obsession_ when the demon acts externally against the person whom he besets, and _possession_ when he acts internally, agitates them, excites their ill humor, makes them utter blasphemy, speak tongues they have never learnt, discovers to them unknown secrets, and inspires them with the knowledge of the obscurest things in philosophy or theology. Saul was agitated and possessed by the evil spirit,[242] who at intervals excited his melancholy humor, and awakened his animosity and jealousy against David, or who, on occasion of the natural movement or impulsion of these dark moods, seized him, agitated him, and disturbed from his usual tenor of mind. Those whom the Gospel speaks of as being possessed,[243] and who cried aloud that Jesus was the Christ, and that he was come to torment them before the time, that he was the Son of God, are instances of possession. But the demon Asmodeus, who beset Sara, the daughter of Raguel,[244] and who killed her first seven husbands; those spoken of in the Gospel, who were simply struck with maladies or incommodities which were thought to be incurable; those whom the Scripture sometimes calls _lunatics_, who foamed at the mouth, who were convulsed, who fled the presence of mankind, who were violent and dangerous, so that they were obliged to be chained to prevent them from striking and maltreating other people; these kinds of persons were simply beset, or obseded by the devil. Opinions are much divided on the matter of obsessions and possessions of the devil. The hardened Jews, and the ancient enemies of the Christian religion, convinced by the evidence of the miracles which they saw worked by Jesus Christ, by his apostles, and by Christians, dared neither dispute their truth nor their reality; but they attributed them to magic, to the prince of the devils, or to the virtue of certain herbs, or of certain natural secrets. St. Justin,[245] Tertullian, Lactantius, St. Cyprian, Minutius, and the other fathers of the first ages of the church, speak of the power which the Christian exorcists exercised over the possessed, so confidently and so freely, that we can doubt neither the certainty nor the evidence of the thing. They call upon their adversaries to bear witness, and pique themselves on making the experiment in their presence, and of forcing to come out of the bodies of the possessed, to declare their names, and acknowledge that those they adore in the pagan temples are but devils.
