This hymn is used for Vespers & Matins on the Feast of the Transfiguration in the Extraordinary Form.
All ye who seek, in hope and love,
For your dear Lord, look up above!
Where, trac’d upon the azure sky,
Faith may a glorious form descry.
Lo! on the trembling verge of light
A something all divinely bright!
Immortal, infinite, sublime!
Older than chaos, space, or time!
Hail, Thou, the Gentiles’ mighty Lord!
All hail, O Israel’s King ador’d!
To Abraham sworn in ages past,
And to his seed while earth shall last.
To Thee the prophets witness bear;
Of Thee the Father doth declare,
That all who would his glory see,
Must hear and must believe in Thee.
To Jesus, from the proud conceal’d,
But evermore to babes reveal’d,
All glory with the Father be,
And Holy Ghost, eternally.
Words: Aurelius Clemens Prudentius, 5th C.; tr. Fr. Edward Caswall, C.O., 1849.
