ET LUX IN TENEBRIS

Chanted by Benedictine Catholic Monks in Spain (San Domingo de Silos Monastery)

And the Light shineth in darkness: and the darkness did not comprehend it...
et lux in tenebris lucet et tenebrae eam non conprehenderunt... erat lux vera quae inluminat omnem hominem venientem in mundum...
That was the True Light, which enlighteneth every man that cometh into this world.
