Excommunicated for Righteous Sake?

This closing chapter is the summary of Isaiah's prophecies as to the last days; hence the similarity of its sentiments with what went before.
The spiritual temple of the heart is G-d's favorite dwelling (John 14:23). In the final state in heaven there shall be "no temple," but "the L-rd G-d" Himself (Rev. 21:22).
[Isa. 66:5] Hear the word of the LORD, ye that tremble at his word; your brethren that hated you, that cast you out for my name's sake, said, Let the LORD be glorified: but he shall appear to your joy, and they shall be ashamed.
Have you been cast out for His name's sake? Excommunicate, as if too polluted to worship with them? Thinking they did G-d good service, John 16:2. Isaiah shows how those with a shallow, empty religion mock those of genuine faith.
First, empty religion hates genuine faith (hated you).
Second, empty religion rejects true faith (cast you out).
Third, empty religion acts in the name of the G-d (for My name's sake).
Fourth, empty religion mocks with spiritual sounding words ("Let the G-d be glorified, that we may see your joy").
Your brethren, who should have loved you and encouraged you for their work's sake hated you, and cast you out of their services, excommunicated you as if you had been the greatest blemishes, when you were really the greatest blessings, of their church and cause of teaching the new-born.
Those that hated Messiah hated His disciples, because they supported His kingdom and interest (John 15:18), and they cast them out for His name's sake. They did not recognize your calling, that you were called by His name, and called upon His name, and laid out yourself to advance His name. Note it is no new thing for church censures to be misapplied, and for her artillery, which was intended for her defense, to be turned against her best friends, by the treachery of her governors.
But they shall be ashamed: Most importantly, empty religion will never ultimately triumph. At the end of days, if not before, they shall be ashamed, when they hear the voice of the G-d, who fully repays His enemies!
How you were encouraged under these persecutions: "Let your faith and patience hold out yet a little while; your enemies hate you and oppress you, your brethren hate you and cast you out, but your Father in heaven loves you, and will appear for you when no one else will or dare. His providence shall order things so as shall be for comfort to you; He shall appear for your joy and for the confusion of those that abuse you and trample on you; they shall be ashamed of their enmity to you."
Lift up your head with joy, knowing that your redemption drew nigh, Luke 21:26, 28. Though G-d seems to hide Himself, He will in due time show Himself.
You may not fit in with their services but you do fit in the Fathers, and vindication is on its way.
