Hillel said “What is hateful to you, do not do to your fellow” (translated from the original).
Somehow that got inverted by Christians to ” do unto others as you would have them do unto you”.
It changed from “do not do” to “do”.
Which has a really big effect on what people do or don’t do to each other. For example, if I truly feel that my soul is at stake and in danger, I would want someone to come and save it, so it would make sense that Christians would proactively go out and try to save people’s souls.
In Judaism the Golden rule is essentially telling us to just keep our hands to ourselves, and stop bothering other people just like we don’t want to be bothered.
At what point did the Golden rule get inverted? When did it turn from a command to keep to yourself and not bother others, to a command to go out and do what one think is best to other people and force one’s beliefs on them?
