O great mystery

Here are two settings of a Gregorian chant which I love. Apparently I'm on a bit of a Latin kick right now. But it is beautiful and the words absolutely swell through me and make my heart soar.

O Magnum Mysterium - Tomás Luis de Victoria - New York Polyphony

O Magnum Mysterium - Morten Lauridsen - Kings College

O magnum mysterium, et admirabile saramentum, ut animalia viderent Dominum natum, jacentem in præsepio! Beata Virgo, cujus viscera meruerunt portare Dominum Christum. Alleluia.

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!
