Eternal Rest
Best for: Praying for someone who has died — at the grave, on an anniversary, in November
Eternal rest grant unto them, O Lord, and let perpetual light shine upon them. May they rest in peace. Amen.
May their souls and the souls of all the faithful departed, through the mercy of God, rest in peace. Amen.
