O magnum mysterium
et admirabile sacramentum,
ut animalia viderent Dominum natum
jacentem in praesepio.
O beata Virgo, cujus viscera meruerunt
portare Dominum Jesum Christum.
Alleluia!
O great mystery
And wonderful sacrament,
That animals should see the new-born Lord
Lying in a manger!
O blessed is the Virgin, whose womb
Was worthy to bear Christ the Lord.
Alleluia!
