To the Name that brings Salvation
Honour, worship, laud we pay:
That for many a generation
Hid in God's foreknowledge lay;
But to every tongue and nation
Holy Church proclaims to-day.
Name of gladness, Name of pleasure,
By the tongue ineffable,
Name of sweetness passing measure,
To the ear delectable,
'Tis our safeguard and our treasure
'Tis our help 'gainst sin and hell.
'Tis the Name for adoration,
'Tis the Name of victory;
'Tis the Name for meditation
In the vale of misery:
'Tis the Name for veneration
By the Citizens on high.
'Tis the Name that whoso preaches
Finds it music in his ear:
'Tis the Name that whoso teaches
Finds more sweet than honey's cheer:
Who its perfect wisdom reaches
Makes his ghostly vision clear.
'Tis the Name by right exalted
Over every other Name:
That when we are sore assaulted
Puts our enemies to shame:
Strength to them that else had halted,
Eyes to blind, and feet to lame.
Jesu, we Thy Name adoring
Long to see Thee as Thou art:
Of Thy clemency imploring
So to write it in our heart,
That, hereafter, upward soaring,
We with Angels may have part. Amen.
