Luke 8:30

He enquires not his name as ignorant of it, but that when the demoniac had confessed the plague which he endured, the power of the Healer might shine forth more welcome to him. But the priests also of our time, who through the grace of exorcism are able to cast out devils, are wont to say that the sufferers can no otherwise be cured than by openly telling in confession every thing which either waking or sleeping they have endured from the unclean spirits, and above all when they imagine that the devils seek and obtain the possession of the human body. So also here the confession is added, And he said, Legion, because many devils were entered into him.

But Jesus asked him, saying: What is your name? And he said: Legion, because many demons have entered into him. He does not inquire the name as if ignorant, but so that the confessed fury endured in front of witnesses, the power of the healer …

Fourth, as regards the company of multitude in the demon responding to the Lord's interrogation, it is added: And Jesus asked him, saying: What is your name? For it belongs to him to interrogate, to whom it also belongs to judge: Wisdom 6: "The Most …

And Jesus asked him, saying, what is thy name?.... This question was put, not out of ignorance in Christ, but for the sake of those that were with him; and partly, that the miserable condition of this man might be the more known; and partly, that his own power might be the more manifest in the dispossession: and he said, legion, because many devils were entered into him; See Gill on Mar 5:9.

The well-known narrative which we have now read, is carefully recorded by all of the first three Gospel-writers. It is a striking instance of our Lord's complete dominion over the evil prince of this world. We see the great enemy of our souls for once completely vanquished — the "strong man" foiled by One stronger than he — and the lion spoiled of his prey. Let us mark, first, in this passage — the miserable condition of those over whom the devil reigns. The picture brought before us is a frightful one.

The well-known narrative which we have now read, is carefully recorded by all of the first three Gospel-writers. It is a striking instance of our Lord's complete dominion over the evil prince of this world. We see the great enemy of our souls for once completely vanquished — the "strong man" foiled by One stronger than he — and the lion spoiled of his prey. Let us mark, first, in this passage — the miserable condition of those over whom the devil reigns. The picture brought before us is a frightful one. We are told that when our Lord arrived in the country of the Gadarenes, "He was met by a demon-possessed man from the town. For a long time this man had not worn clothes or lived in a house — but had lived in the tombs." We are also told that although he had been "bound with chains and in fetters — he broke the chains, and was driven by the devil into the wilderness." In short, the case seems to have been one of the most aggravated forms of demon possession. The unhappy sufferer was under the complete dominion of Satan — both in body and soul. As long as he continued in this state — he must have been a burden and a trouble to all around him. His mental faculties were under the control of a "legion" of demons. His bodily strength was only employed for his own injury and shame. It is difficult to conceive of a more pitiable state for mortal man to be in! Cases of bodily possession by Satan, like this, are, to say the least, very rarely met with in modern times. Yet we must not, on this account, forget that the devil is continually exercising a fearful power over many hearts and souls. He still urges many, in whose hearts he reigns, into self-dishonoring and self-destroying habits of life. He still rules many with a rod of iron. He goads them on from vice to vice, and from profligacy to profligacy.
