Paul didn't want any "help" from a devil regardless of the kind.
My take away from this passage is that even if a demon speaks the truth about something, they are to be rebuked and authority established to not permit them any part in the church's ministry. I know of examples that some Christians would regard as "unchristian." They mistakenly are taught that you should allow anyone into the congregation and that they should be given opportunities to influence others.
A literal lesbian/ bi pagan was allowed to teach young children in an evangelical church. That should not happen. The woman actually was caught praying to demons.
A man possessed with a demon calling itself "Michael the Archangel" insisted the pastor read what it had written to the congregation. The demon timed his attack perfectly in sinc with the demonically influenced staff members that were leading others astray and being fired at that moment.
The demon was cast out of the church and the pastor charged with being a meanie.
The world loves their own and want feminized men in pulpits and men who submit to the devil in the name of their view of Jesus from a movie or somewhere unbiblical.
My former church had a demonized woman enter and take over a part of the service and try to cast a spell before the whole congregation. We ushers escorted her out as she raved.
So called believers and the media agree with the demons by insisting that they are allowed to speak to the churches. Then they demonize those who rebuke them. Some demons are smart and know how to manipulate. However, their strategy is often predictable.
Jesus rebuked them, told them to shut up and threw them out of the lost into pigs to be cast into the sea until they would be cast into the lake of fire at a later time.
Yeah its sad honestly, I have met a number of people who led "churches" and we part of other groups that are pagan, but they act in front of everyone. One place people kept leaving and the guy said they were "fall aways" then when the people I knew that went to his "church" found out about what the guy was really doing they also left, certianly he also called them "fall aways." But not long after he went full wacko and began doing the same stuff you said that lady was doing, sad that people look to other humans like that and get misled.
Here's one that someone was able to video record.
Demon Insistent on Changing the Name of the Lord
You'll find people who are highly influenced by these demons, like the one above, in this and other forums. Listen to hear if it sounds familiar.
The Scripture also records evil seeking to remove/replace His Name:
Jeremiah 23:26-27, "How long will this be in the heart of the prophets who prophesy lies? Yes, they are prophets of the deceit of their own minds; Who devise; plan and scheme, to cause My people to forget My Name through their dreams, which they tell every man to his neighbor, just as their fathers have forgotten My Name for Baal."
BAAL (DEITY) [Hebrew - baal] . Canaanite storm and fertility god. The name, which means “lord, ” is an epithet of the god Hadad (lit. “thunderer” ). Well-known from the OT, he is now extremely well-attested in the Ugaritic texts, in addition to being mentioned in other ancient texts. (Freedman, David Noel: The Anchor Bible Dictionary. New York : Doubleday, 1996, c1992, S. 1:546)
