O magnum mysterium et admirabile sacramentum,
ut animalia viderent Dominum natum,
jacentem in præsepio.
Beata virgo, cujus viscera meruerunt portare Dominum Christum,
O great mystery and wondrous sacrament,
that animals should see the newborn Lord lying in their manger.
Blessed is the Virgin whose womb was worthy to bear the Lord Jesus Christ.
