Particularly some bible teachings? Now I know the bible is used as an excuse for some very biggotted behaviour so obviously I'm being selective but things like "unclean" foods are there things thatvwoukd likely have made you I'll in a world without good hygiene and refrigeration.
An old memory came to me today while I'm run ing around like a mad person, trying to get a week's worth of chores done. My Grandma was an avid follower of the day of rest. I remember her horror at seeing the vicar cutting his grass on a Sunday.
AIBU to think that a society that imposed one day of rest a week actually knew what it was doing?
