The Sixteen

Traditional

Resonet in laudibus
cum iucundis plausibus
Sion cum fidelibus:
Apparuit quem genuit Maria.

Sunt impleta quae praedixit
Gabriel: eia.
Virgo Deum genuit,
quem divina voluit
clementia.

Hodie apparuit
in Israel:
ex Maria virgine
est natus Rex.

Magnum nomen Domini
Emmanuel,
quod annunciatum est
per Gabriel.
