While Jesus was still speaking--the tense of the verb implies an unfinished discourse--suddenly He was interrupted by a loud, wild shout: "Ah, what have we to do with Thee, Thou Jesus of Nazareth? Art Thou come to destroy us? I know Thee, who Thou art, the Holy One of God." It was the cry of a man who, as our Evangelist expresses it, "had a spirit of an unclean devil." The phrase is a singular one, in fact unique, and savours a little of tautology; for St. Luke uses the words "spirit" and "devil" as synonyms (ix. 39). Later in his Gospel he would simply have said "he had an unclean devil;" why, then, does he here amplify the phrase, and say he had "a spirit of an unclean devil"? We can, of course, only conjecture, but might it not be because to the Gentile mind--to which he is writing--the powers of evil were represented as personifications, having a corporeal existence? And so in his first reference to demoniacal possession he pauses to explain that these demons are evil "spirits," with existences altogether separate from the diseased humanity which temporarily they were allowed to inhabit and to rule. Neither can we determine with certainty the meaning of the phrase "an unclean devil," though probably it was so called because it drove its victim to haunt unclean places, like the Gadarene, who had his dwelling among the tombs. The whole subject of demonology has been called in question by certain modern critics. They aver that it is simply an after-growth of Paganism, the seeds of worn-out mythologies which had been blown over into the Christian mind; and eliminating from them all that is supernatural, they reduce the so-called "possessions" to the natural effects of purely natural causes, physical and mental. It is confessedly a subject difficult as it is mysterious; but we are not inclined, at the bidding of rationalistic clamour, so to strike out the supernatural. Indeed, we cannot, without impaling ourselves upon this dilemma, that Jesus, knowingly or unknowingly, taught as the truth what was not true. That Jesus lent the weight of His testimony to the popular belief is evident; never once, in all His allusions, does He call it in question, nor hint that He is speaking now only in an accommodated sense, borrowing the accents of current speech. To Him the existence and presence of evil spirits was just as patent and as solemn a fact as was the existence of the arch-spirit, even Satan himself. And granting the existence of evil spirits, who will show us the line of limitation, the "Hitherto, but no farther," where their influence is stayed? Have we not seen, in mesmerism, cases of real possession, where the weaker human will has been completely overpowered by the stronger will? when the subject was no longer himself, but his thoughts, words, and acts were those of another? And are there not, in the experiences of all medical men, and of ministers of religion, cases of depravity so utterly foul and
