I am the living Bread which came down from Heaven: if any man eat of this Bread, he shall live forever: and the Bread that I will give is My flesh, which I will give for the life of the world.@John 6:51
James R. Woodford (1820–1885)

Thomas Aquinas (1226–1274) (Adoro Te devote, latens Deitas); translated from Latin to English by James R. Woodford, 1850, & the compilers of Hymns Ancient and Modern.

Adoro Te Devote, traditional melody (🔊 pdf nwc).

Thomas Aquinas (1226–1274)

Thee we adore, O hidden Savior, Thee,
Who in Thy sacrament dost deign to be;
Both flesh and spirit at Thy presence fail,
Yet here Thy presence we devoutly hail.

O blest memorial of our dying Lord,
Who living Bread to men doth here afford!
O may our souls forever feed on Thee,
And Thou, O Christ, forever precious be.

Fountain of gladness, Jesu, Lord and God,
Cleanse us, unclean, with Thy most cleansing blood;
Increase our faith and love, that we may know
The hope and peace which from Thy presence flow.

O Christ, whom now beneath a veil we see,
May what we thirst for soon our portion be,
To gaze on Thee unveiled, and see Thy face,
The vision of Thy glory and Thy grace.
