It’s a minor pet peeve, but it is everywhere today so errrr…. please keep in mind that “Rest in Peace”/RIP literally comes from a latin phrase and is a very very deeply Christian expression.
When talking about the departed, Jews say “may their memory be a blessing.”
So please, when talking about a dead person who is Jewish, try to keep in mind that RIP is a Christian phrase.
I learned something today, so I’ll pass it on so someone else can learn too
