How Exorcisms are Performed
How do priesthood holders perform exorcisms? Do they need some priesthood keys?
An exorcism can be performed in the manner of any priesthood blessing. Usually it involves 2 people giving the blessing, as the more faith the better. The person speaking quotes their authority after quoting the person being blessed's full name. Then words are expressed according to inspiration given. It is then closed in the name of Jesus Christ, and amen is stated.
The priesthood keys give those priesthood holders an automatic right to receive revelation on what words are stated in the blessing.
If you are dealing with someone that you know for a fact has an evil spirit within them then you should anticipate resistance to being expelled, by the evil spirit: It will fight to stay in the body. If the person is still wobbling about and/or you see the evil spirit in the victims eyes then you haven't succeeded yet. If it hasn't gone after one try then stay there until you get it to come out.
Be careful that it doesn't move from one person to another. Therefore it is better that you clear the house of other people. Also remember that the person it is being expelled from must change their ways or it will just return with a vengeance. Note the following advice from Christ _
"When the unclean spirit is gone out of a man, he walks through dry places, seeking rest; and finding none, he says, I will return to my house where I came out. And when he comes, he finds it swept and garnished. Then he goes, 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 11:24-26
Christ also advises fasting and praying first as being very helpful (Mark 9:29). I'd suggest at least a 24 hour fast.
I'd strongly advise any person taking on such a task to make sure you have the appropriate priesthood (Melchizedek) first. Please note the following from the New Testament _
"Then certain of the vagabond Jews, exorcists, took upon themselves to call over them which had evil spirits in the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preaches. 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 you? 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." Acts 19:13-16
