Requiem aeternam dona eis, Domine.
Et lux perpetua luceat eis.
Te decet hymnus, Deus, in Sion,
Et tibi reddetur votum in Jerusalem
Exaudi orationem meam
Ad te omnis caro veniet.
In paradisum deducant angeli;
in tuo adventu suscipiant te martyrus
et perducant te in civitatem sanctam Jerusalem.
Chorus angelorum te suscipat
et cum Lazaro, quondam paupere,
aeternam habeas requiem.
When I was in eighth grade, many moons ago, I went to a church connected Catholic school. The Dominican nun who taught us our regular school work also taught us music and we sang(in Latin) all of the funeral masses of the parish. I think that I see within what you posted part of a hymn that I knew as "To Paradise". That was the only one we sang in English and not Latin. We sang it as the recessional. It stuck with me because it had a sad and haunting quality.
