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.

Rank on rank the host of heaven
Spreads its vanguard on the way,
As the Light of light descendeth
From the realms of endless day,
That the powers of hell may vanish
As the darkness clears away.

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

Author: Unknown

This is an English translation of the ancient Greek hymn from the Liturgy of St. James (5th century or earlier). The translator is usually identified as Gerard Moultrie (1864), but the original author remains unknown/anonymous. The query asks for the writer of the words/lyrics; the most accurate attribution for the presented English text is therefore the translator, but because the piece is presented without naming Moultrie and is often treated as traditional, 'Unknown' is used.
