The Dies Irae used to be the sequence for the Requiem Mass, before Bugnini removed it during the liturgical reforms. And I quote:Requiem æternam dona eis, Domine,et lux perpetua luceat eis. Requiescat in pace. (Eternal Rest, grant unto him (her) O Lord, and let perpetual light shine upon them. May he (her) rest in peace.
"They got rid of texts that smacked of a negative spirituality inherited from the Middle Ages. Thus they removed such familiar and even beloved texts as the "Libera me, Domine", the "Dies Iræ", and others that overemphasized judgment, fear, and despair. These they replaced with texts urging Christian hope and arguably giving more effective expression to faith in the resurrection."Bugnini is absolutely wrong, and the Mass of Christian Burial is an instant-canonization service for many.
Today at Christendom College, where I am visiting for the weekend, Fr Planty said Mass ad orientem, in Latin, as is usual at the 11:30 on Fridays, wearing a black Roman-cut chasuble and with a stole crossed his body. It was beautiful, and the cantor chanted the Dies Irae as a motet at Communion. Beautiful; excellent homily too.
