Wrong. They have the authority to decide who gets what "privileges" in the congregation. And they have the authority to strip people of those privileges. And they have the authority to expel people from the congregation if they arbitrarily decide that they aren't repentant enough for their sins.
You're either a liar, trying to deceive less knowledgable people who may be lurking, or you simply have no idea what you're talking about
