Libera me

Líbera me ("Deliver me") is a Roman Catholic responsory that is sung in the Office of the Dead and at the absolution of the dead, a service of prayers for the dead said beside the coffin immediately after the Requiem Mass and before burial. The text of Libera Me asks God to have mercy upon the deceased person at the Last Judgment. In addition to the Gregorian chant in the Roman Gradual, many composers have written settings for the text, including Tomás Luis de Victoria, Anton Bruckner (two settings), Giuseppe Verdi, Gabriel Fauré, Maurice Duruflé, Igor Stravinsky, Benjamin Britten, Krzysztof Penderecki and David Maslanka.

Líbera me, Dómine, de morte ætérna, in die illa treménda.
Quando cœli movéndi sunt et terra.
Dum véneris iudicáre sǽculum per ignem.
Tremens factus sum ego, et tímeo, dum discússio vénerit, atque ventúra ira.
Quando cœli movendi sunt et terra.
Dies illa, dies iræ, calamitátis et misériæ, dies magna et amára valde.
Dum véneris iudicáre sǽculum per ignem.
Réquiem ætérnam dona eis, Dómine: et lux perpétua lúceat eis.
