La Belleza del Espiritu Sancto - Harpa Dei

This is one of the most beautiful things I’ve ever seen on YouTube.
The highlights for me were O Virgin Pure at minute 12. The Swahili Ave María at minute 29 and the last song written by Saint Hildegard at minute 51.
The notes of one of the compositions is even read from the stars on the cloak of Our Lady Guadalupe and sung in the Aztec language of San Juan Diego.
Enjoy.

Here are the beautiful words to the Orthodox Hymn O Bride Unwedded.

O Virgin pure, immaculate/ O Lady Theotokos
O Virgin Mother, Queen of all/ and fleece which is all dewy
More radiant than the rays of sun/ and higher than the heavens
Delight of virgin choruses/ superior to Angels.
Much brighter than the firmament/ and purer than the sun's light
More holy than the multitude/ of all the heav'nly armies.
Rejoice, O Bride Unwedded!
O Ever Virgin Mary/ of all the world, the Lady
O bride all pure, immaculate/ O Lady Panagia
O Mary bride and Queen of all/ our cause of jubilation
Majestic maiden, Queen of all/ O our most holy Mother
More hon'rable than Cherubim/ beyond compare more glorious
than immaterial Seraphim/ and greater than angelic thrones.
Rejoice, O Bride Unwedded!
Rejoice, O song of Cherubim/ Rejoice, O hymn of angels
Rejoice, O ode of Seraphim/ the joy of the archangels
Rejoice, O peace and happiness/ the harbor of salvation
O sacred chamber of the Word/ flow'r of incorruption
Rejoice, delightful paradise/ of blessed life eternal
Rejoice, O wood and tree of life/ the fount of immortality.
Rejoice, O Bride Unwedded!
I supplicate you, Lady/ now do I call upon you
And I beseech you, Queen of all/ I beg of you your favor
Majestic maiden, spotless one/ O Lady Panagia
I call upon you fervently/ O sacred, hallowed temple
Assist me and deliver me/ protect me from the enemy
And make me an inheritor/ of blessed life eternal.
Rejoice, O Bride Unwedded!
