The Great Mystery is a nice bit of Literny from the Roman Catholic Tradition, often used as an Antiphone
Latin text
O magnum mysterium,
et admirabile sacramentum,
ut animalia viderent Dominum natum,
jacentem in praesepio!
Beata Virgo, cujus viscera
meruerunt portare
Dominum Christum.
Alleluia.
English translation
O great mystery,
and wonderful sacrament,
that animals should see the new-born Lord,
lying in a manger!
Blessed is the Virgin whose womb
was worthy to bear
Christ the Lord.
Alleluia!
Another Carol from Russia, which was turned into a carillion on bells

...and finally for now I leave you with the etherial Golden Light (Lux Aurumque)

Lux,
calida gravisque pura velut aurum
et canunt angeli molliter
modo natum.
English Lyrics:
Light,
warm and heavy as pure gold
and the angels sing softly
to the new-born baby
