"You will know my people by the love they have amongst themselves", (or somesuch), guess that rules out the Witnesses then, even when they have said Love, they arnt allowed to actually demonstrate it in case they all have sex with each other or some such nonsense.
"My people will know my name", is an identifying scripture, well the JWs admit Gods name is more likely to be Yahwey so why are they then using the name Jehovah?
