In 20 AD Jesus Christ said "Do unto others as you would have them do unto you UNLESS you are full of shit!"
He called this his "Golden Stool" (back then Stool meant what we would call today "Shit" or Turd" or "Bullshit". in Ancient Greek Aramaic.)
When the Priests decided to use him as the front man for their new religion (Christianity) -They felt "Golden STOOL" was not the best name for Jesus' basic philosophy SO they changed "Stool" to "Rule" AND SO it came down through the millenia as
"The Golden RULE"
