What about Excommunication? Sometimes it is commanded of God to bring condemnation upon unrighteous dominion by the wicked priests of King Noah, in the case of Abinadi in the Book of Mormon, for example and in the case of the man healed of blindness being cast out of their (Jew's) synagogues!

 11 But Alma said unto him: The Spirit constraineth me that I must not stretch forth mine hand; for behold the Lord receiveth them up unto himself, in glory; and he doth suffer that they may do this thing, or that the people may do this thing unto them, according to the hardness of their hearts, that the judgments which he shall exercise upon them in his wrath may be just; and the blood of the innocent shall stand as a witness against them, yea, and cry mightily against them at the last day.

(Alma 14:11)

"Persons sometimes say that they have enjoyed the spirit of the work as much since they were cut off as while they were in the Church. Have they enjoyed the Spirit? Yes. Why? Simply because they were wrongfully cut off. They were cut off in such a way that it did not take the Spirit of God from them. And the reason why they were cut was because they did not come up to the particular standard of perfection of those who dealt with them, or they did not come up to their feelings. I have heard of a man who was cut off because he would not believe that Adam was our Father and God. `Well, but was it not so?' Its being so does not change the fact that we are sinners and need salvation, and such preaching does not help men and women to repent of their sins." (Mill. Star 24:99)

 

So we answer, yes, it is a blessing to those unrighteously handled as was Jesus and Paul!

 34 They answered and said unto him, Thou wast altogether born in sins, and dost thou teach us? And they cast him out (excommunicated him).
35 Jesus heard that they (chief rulers of he synagogue) had cast him out (excommunicated him); and when he had found him, he said unto him, Dost thou believe on the Son of God?
36 He answered and said, Who is he, Lord, that I might believe on him?
37 And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee.
38 And he said, Lord, I believe. And he worshipped him.

(John 9:34-38)
 

I cast devils out of Shirley's body after being "cut off the Church". A devil cannot cast out a devil as per the statement of Jesus, my Jesus:

24 But when the Pharisees heard [it], they said, This [fellow] doth not cast out devils, but by Beelzebub the prince of the devils. 25 And Jesus knew their thoughts, and said unto them, Every kingdom divided against itself is brought to desolation; and every city or house divided against itself shall not stand:
26 And if Satan cast out Satan, he is divided against himself; how shall then his kingdom stand? 27 And if I by Beelzebub cast out devils, by whom do your children cast [them] out? therefore they shall be your judges. 28 But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you.

(Matt 12:24-28)

EXCOMMUNICATION

"Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue: For they loved the praise of men more than the praise of God." (John 12:42-43)

"These things have I spoken unto you, that ye should not be offended. They shall put you out of the synagogues." (John 16:2)

"You cannot take any man's priesthood away without transgression." (John Taylor, Times Seasons 6:922)

"The next day the Prophet came to our home and stopped in our carpenter shop and stood by the turning lathe. I went and got my map for him. `Now,' he said, `I will show you the travels of this people.' He then showed our travels thru Iowa, and said, `Here you will make a place for the winter; and here you will travel west until you come to the valley of the Great Salt Lake! You will build cities to the North and to the South, and to the East and to the West; and you will become a great and wealthy people in that land. *** You will live to see men arise in power in the Church who will seek to put down your friends and the friends of our Lord and Savior, Jesus Christ. Many will be hoisted because of their money and the worldly learning which they seem to be in possession of; and many who are the true followers of our Lord and Savior will be cast down because of their poverty.'" (Mosiah Hancock Journal, p. 19)

"No endowments or blessings in the house of the Lord, no patriarchal blessings, no ordination to the Priesthood, can be taken away, once given. To prevent a person for (just) cause from exercising the rights and privileges of acting in the offices of the Priesthood (within the Church: brackets ours), may be and has been done, and the person so silenced still remain a member of the Church, but this does not take away from him any priesthood that he held." (Joseph F. Smith, Imp. Era. 11:466)

"Persons sometimes say that they have enjoyed the spirit of the work as much since they were cut off as while they were in the Church. Have they enjoyed the Spirit? Yes. Why? Simply because they were wrongfully cut off. They were cut off in such a way that it did not take the Spirit of God from them.

Its being so does not change the fact that we are sinners and need salvation, and such preaching does not help men and women to repent of their sins." (Mill. Star 24:99)

"After that he [John Taylor] talked for about an hour and then sat down and wrote the revelation which was given him by the Lord upon the question of Plural Marriage. Then he talked to us for some time, and said, `Some of you will be handled and ostracized and cast out from the Church by your brethren because of your faithfulness and integrity this principle, and some of you may have to surrender your lives because of the same, but woe, woe, unto those who shall bring these troubles upon you.'" (Statement by Lorin C. Woolley, Questions on Plural Marriage, Dennis R. Short, p. 67)
