Shunning is an ancient way to treat people who have different beliefs or practices.
The term ostracism comes from the practice of writing a person's name on pieces of pottery called ostracons in ancient Greece and tallying up how many had voted for a person to leave Athens.
How come JWs believe shunning is from Jehovah through the faithfull slave if they did it in Greece two and a half thousand years ago and they worshipped Zeus and Hera?
