Let all mortal flesh keep silence

Let all mortal flesh keep silence,
And with fear and trembling stand;
Ponder nothing earthly-minded,
For with blessing in his hand,
Christ our God to earth descendeth,
Our full homage to demand.

King of kings, yet born of Mary,
As of old on earth he stood,
Lord of lords, in human vesture,
In the body and the blood;
He will give to all the faithful
His own self for heavenly food.

At his feet the six-winged seraph,
Cherubim, with sleepless eye,
Veil their faces to the presence,
As with ceaseless voice they cry:
Alleluia, Alleluia,
Alleluia, Lord Most High!
