O magnum mysterium, et admirable sacramentum, ut animalia viderent Dominum natum, jacentum in praesepio!
Beata Virgo, cujus viscera meruerunt portare Dominum Christum. Alleluia!
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. Alleluia!
