Hodie Christus natus est;
hodie Salvator apparuit;
hodie in terra canunt angeli, letantur archangeli;
hodie exultent justi, dicentes:
Gloria in excelsis Deo! Alleluia.

On this day Christ was born for us;
on this day the Saviour appeared to us;
on this day on the earth sing with the angels, rejoicing with archangels;
on this day exult, ye righteous, saying:
Glory be to God in the highest! Alleluya.
