Eternal Rest — The Prayer for the Dead
The prayer the Church has said over her dead for centuries — in English and in the Latin of the Requiem.
Catholics do not abandon their dead to silence. We pray for them — that God, in His mercy, would bring the faithful departed through their purification into the perfect light of heaven. The Eternal Rest is the prayer the Church puts in every Catholic's mouth for that purpose: short enough to say at a graveside, ancient enough to have been said over a thousand years of them.

In Latin (Requiem aeternam)
When to pray it
Pray it whenever you remember your dead — at the moment of a death, at the graveside, on the anniversary, and especially in November, the month the Church devotes to the Holy Souls, beginning with All Souls' Day (November 2). It is the natural response to hearing that someone has died: not "rest in peace" as a slogan, but as a petition you actually make to God.
Why Catholics pray for the dead
The prayer rests on two ancient convictions: that there is a purification after death (what the Church calls Purgatory), and that the living can help the dead by prayer. The wording itself echoes the Mass for the Dead, whose introit antiphon draws on 2 Esdras 2:34–35. This is not optional sentiment but a work of mercy — the Catechism names praying for the dead among the spiritual works of mercy (cf. CCC §1032).
