- O Emmanuel, Rex et legifer noster,
- exspectatio Gentium, et Salvator earum:
- veni ad salvandum nos, Domine, Deus noster.
or in English:
- O Emmanuel, our king and our lawgiver,
- the hope of the nations and their Saviour:
- Come and save us, O Lord our God.
It's based on one of the most familiar of the Advent/Christmas readings:
"Therefore the Lord himself will give you a sign. Look, the young woman is with child and shall bear a son, and shall name him Immanuel." Isaiah 7:14
