O Virgin Pure
Plagal First Tone (Tone 5)
 
Refrain: Rejoice, O Unwedded Bride!
 
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 Unwedded Bride! 

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 Unwedded Bride!

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 Unwedded Bride!

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 Unwedded Bride!
