O admirabile commercium, creator generis humani animatum corpus sumens de virgine nasci dignatus est et procedens homo sine semine largitus est nobis suam deitatem.

Germinavit radix Iesse, orta est stella ex Iacob, virgo peperit salvatorem, te laudamus deus noster.



English translation: 

O admirable exchange: the creator of the humankind, taking on a living body deemed worthy to be born of a virgin, and, coming forth without seed as a man, gave us his deity.

The root of Jesse germinated, a star arose from Jacob, a virgin gave birth to the saviour. We praise you, our God.
