Latin:

Quem pastores laudavere
Quibus angeli dixere
Absit vobis jam timere
Natus est rex gloriae
Ad quem magi ambulabant
Aurum, thus, myrrham portabant
Immolabant haec sincere
Nato regi gloriae
Christo regi, Deo nato
Per Mariam nobis dato
Merito resonet vere
Laus, honor et gloria

English:

Shepherds left their flocks a-straying
God's command with joy obeying
When they heard the angel saying:
"Christ is born in Bethlehem."

Wise Men came from far, and saw him
Knelt in homage to adore him;
Precious gifts they laid before him:
Gold and frankincense and myrrh
Let us now in every nation
Sing his praise with exultation
All the world shall find salvation
In the birth of Mary's Son
