Seven brothers, sons of a Jewish chief priest named Sceva, attempted an exorcism in Ephesus using a Name they had no standing in: I adjure you by the Jesus whom Paul preaches. The spirit’s reply is one of the coldest sentences in the New Testament: Jesus I know, and Paul I know — but who are ye? The possessed man then set upon all seven, stripped them, and drove them bleeding from the house.
The Casting-Out chapter uses this as the clearest demonstration of what borrowed, ungrounded authority does. The sons of Sceva invoked a reference they could not trace back to themselves — a Name that pointed genuinely outside the loop, but not their loop. Invoking it without the standing to do so is not neutral; it does not merely fail. It recoils. The spirit treated the gap between the invoked authority and the invokers’ actual position as an opening rather than a barrier.
The structural lesson: you cannot expel a sovereign with a peer, and you cannot expel one with a peer’s borrowed credential either. The exorcism operation requires appeal up the chain — all the way to the reference that cannot itself be captured, because it refuses to be located. Anything short of that is not a third point; it is the loop wearing a third point’s name.
