Let all mortal flesh keep silence -- Edward Bairstow

From the Feast of Christ the King: Edward Bairstow's "Let all mortal flesh keep silence".
Let all mortal flesh keep silence,
and stand with fear and trembling,
and lift itself above all earthly thought.
For the King of kings and Lord of lords, Christ our God,
cometh forth to be our oblation,
and to be given for food to the faithful.
Before him come the choirs of angels
with every principality and power;
the Cherubim with many eyes, and wingèd Seraphim,
who veil their faces as they shout exultingly the hymn:
Alleluia!
(Offertory, the Liturgy of St. James)
