And that, by definition, is hypocrisy. And if the split with Chu is based on lies, deceit and hypocrisy it was not authorized by the Lord. And if they acted without authorization in excommunicating brothers and churches they are worthy of being judged. Therefore they will be judged by their own words.
The point is that "it all revolves around WL" in word but not in fact. The reality is they have ulterior motives and use "being faithful to WL" as some kind of bogus justification. Expose that lie and the structure they have built up collapses. The point is this is their action that they must be held accountable for. They do not have "plausible deniability". WL was dead. WL never excommunicated TC. If they can complain about being held accountable for WL sins, then this is a case where it is not WL's sin, it is their sin.
