What does 'Rest In Peace' mean, and would you say that someone who has not died in Christ can rest in peace...Just curious about what other think about this...
It means requesat in pacem... Latin for "To be sung into restful peace," and you are correct. The singing part is for the soul. It's like elevator music or a lullaby.
(Took Latin in 7th Grade)
ETA: This was NOT carved into the tombstones of pagans or atheists, but for Catholics.
