If Raymond franz had used prostitutes and was a narcissist would it make crisis of conscience any less valuable? It would be a shame they weren’t an upstanding human that we could respect but C OF C would still be accurate and useful
Yes, if the facts of your hypothetical were true, it would make COC less valuable because adultery, regardless of whether it's with a paid prostitute or anyone else, has a negative bearing on the credibility of the adulterer. Put simply, if a person is cheating on his wife who later discovers his adultery, the wife will likely never trust her husband to be honest ever again. Why would anyone of sound mind and reasonable intelligence expect an adulterer to be honest with anyone else?
Unlike the slob that you are here to support, I am unaware of any allegations of adultery made against Raymond Franz.
