Can a person be possessed by an evil spirit / angel?Yes!
How it is done we do not know for sure since scripture does not tell us. One could assume
by living contrary to Gods word, or wanting to communicate with evil angels
might facilitate it.
What Defines Demonic Possession?
Demonic possession involves the involuntary loss of control of ones faculties and emotions.
Also, though incomprehensible, a person can have more than one demonic spirit
residing within them.
(Matthew 4:24) "And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them."
(Mark 1:23-27) "And there was in their synagogue a man with an unclean spirit; and he cried out, Saying, Let us alone; 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. And Jesus rebuked him, saying, Hold thy peace, and come out of him. And when the unclean spirit had torn him, and cried with a loud voice, he came out of him. And they were all amazed, insomuch that they questioned among themselves, saying, What thing is this? what new doctrine is this? for with authority commandeth he even the unclean spirits, and they do obey him."
(Mark 1:34) "And he healed many that were sick of divers diseases, and cast out many devils; and suffered not the devils to speak, because they knew him."
(Mark 5:2-18) "And when he was come out of the ship, immediately there met him out of the tombs a man with an unclean spirit, Who had his dwelling among the tombs; and no man could bind him, no, not with chains: Because that he had been often bound with fetters and chains, and the chains had been plucked asunder by him, and the fetters broken in pieces: neither could any man tame him. And always, night and day, he was in the mountains, and in the tombs, crying, and cutting himself with stones. But when he saw Jesus afar off, he ran and worshipped him, And cried with a loud voice, and said, What have I to do with thee, Jesus, thou Son of the most high God? I adjure thee by God, that thou torment me not. For he said unto him, Come out of the man, thou unclean spirit. And he asked him, What is thy name? And he answered, saying, My name is Legion: for we are many. And he besought him much that he would not send them away out of the country. Now there was there nigh unto the mountains a great herd of swine feeding. And all the devils besought him, saying, Send us into the swine, that we may enter into them. And forthwith Jesus gave them leave. And the unclean spirits went out, and entered into the swine: and the herd ran violently down a steep place into the sea, (they were about two
thousand;) " and were choked in the sea. And they that fed the swine fled, and told it in the city, and in the country. And they went out to see what it was that was done. And they come to Jesus, and see him that was possessed with the devil, and had the legion, sitting, and clothed, and in his right mind: and they were afraid. And they that saw it told them how it befell to him that was possessed with the devil, and also concerning the swine. And they began to pray him to depart out of their coasts. And when he was come into the ship, he that had been possessed with the devil prayed him that he might be with him."
(Mark 7:25-30) "For a certain woman, whose young daughter had an unclean spirit, heard of him, and came and fell at his feet: The woman was a Greek, a Syrophenician by nation; and she besought him that he would cast forth the devil out of her daughter. But Jesus said unto her, Let the children first be filled: for it is not meet to take the children's bread, and to cast it unto the dogs. And she answered and said unto him, Yes, Lord: yet the dogs under the table eat of the children's crumbs. And he said unto her, For this saying go thy way; the devil is gone out of thy daughter. And when she was come to her house, she found the devil gone out, and her daughter laid upon the bed."
(Luke 4:33-35) "And in the synagogue there was a man, which had a spirit of an unclean devil, and cried out with a loud voice, Saying, Let us alone; 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. And Jesus rebuked him, saying, Hold thy peace, and come out of him. And when the devil had thrown him in the midst, he came out of him, and hurt him
(Luke 4:41) "And devils also came out of many, crying out, and saying, Thou art Christ the Son of God. And he rebuking them suffered them not to speak: for they knew that he was Christ."
(Luke 8:2) "And certain women, which had been healed of evil spirits and infirmities, Mary called Magdalene, out of whom went seven devils,"
(Luke 8:27-33) "And when he went forth to land, there met him out of the city a certain man, which had devils long time, and ware no clothes, neither abode in any house, but in the tombs. When he saw Jesus, he cried out, and fell down before him, and with a loud voice said, What have I to do with thee, Jesus, thou Son of God most high? I beseech thee, torment me not. (For he had commanded the unclean spirit to come out of the man. For oftentimes it had caught him: and he was kept bound with chains and in fetters; and he brake the bands, and was driven of the devil into the
wilderness.) " And Jesus asked him, saying, What is thy name? And he said, Legion: because many devils were entered into him.
And they besought him that he would not command them to go out into the
deep. And there was there an herd of many swine feeding on the mountain: and they besought him that he would suffer them to enter into them. And he suffered them. Then went the devils out of the man, and entered into the swine: and
the herd ran violently down a steep place into the lake, and were choked."
I find it interesting that they asked to not be sent into the deep. Could
it be that the angels that sinned are being held in the deepest of waters
where it is eternally dark and thus asked not to be sent back to the deep.
Even more interesting is that Jesus did not say he would not send them back,
only that they could enter the swine. After allowing them to enter the
swine, the swine ended up sending them back into the water anyways.
(2 Peter 2:4-5) "For if God spared not the angels that sinned, but cast them down to
hell (G5020), and delivered them into chains of darkness (G2217), to be reserved unto judgment; And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the
G5020 = (the deepest abyss of Hades); to incarcerate in eternal torment: - cast down to hell. G2217 = Akin to the base of G3509; gloom (as shrouding like a
cloud): - blackness, darkness, mist.
Both cloud and mist are in context with water, another clue?
The angels were cast so far down as to be out of sight and darkness. Their place of restraint was so far down that one would think they would never be able to
get out, but some have managed to escape, maybe with Satan's help, since he
is the one who reigns upon the earth at this time.
(Luke 9:39-42) "And, lo, a spirit taketh him, and he suddenly crieth out; and it teareth him that he foameth again, and bruising him hardly departeth from him. And I besought thy disciples to cast him out; and they could not. And Jesus answering said, O faithless and perverse generation, how long shall I be with you, and suffer you? Bring thy son hither. And as he was yet a coming, the devil threw him down, and tare him. And Jesus rebuked the unclean spirit, and healed the child, and delivered him again to his father."
(Luke 10:17) "And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name."
(Luke 11:24-26)"When the unclean spirit is gone out of a man, he
walks through dry places, seeking rest; and finding none, he saith, I will
return unto my house whence I came out. And when he comes, he finds it swept
and garnished. Then goes he, and takes to him seven other spirits more
wicked than himself; and they enter in, and dwell there: and the last state
of that man is worse than the first."
(Luke 13:16) "And ought not this woman, being a daughter of Abraham, whom Satan hath bound, lo, these eighteen years, be loosed from this bond on the sabbath day?"
(Luke 22:3) "Then entered Satan into Judas surnamed Iscariot, being of the number of the twelve."
(Acts 5:14-16) "And believers were the more added to the Lord, multitudes both of men and women.) Insomuch that they brought forth the sick into the streets, and laid them on beds and couches, that at the least the shadow of Peter passing by might overshadow some of them. There came also a multitude out of the cities round about unto Jerusalem, bringing sick folks, and them which were vexed with unclean spirits: and they were healed every one."
(Acts 16:16)"And it came to pass, as we went to prayer, a certain
damsel possessed with a spirit of divination met us,"
(Acts 8:7) "For unclean spirits, crying with loud voice, came out of many that were possessed with them: and many taken with palsies, and that were lame, were healed."
(Acts 10:38) "How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him."
(Acts 19:11-16) "And God wrought special miracles by the hands of Paul: So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them. Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth. And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so. And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded."
